Construction loan monitoring, explained.

A loan against a building that does not exist yet, and its two weak points: cost and time

The life of one construction loan, in five steps

1. The loan closes on a budget and a scheduleHarrow Yard closes on April 14, 2025: a $71.8 million budget, $19.4 million of the developer's equity in first, completion planned for January 15, 2027.
2. Draws pay for the work each monthAn inspector checks the work; the bank tests the draw against the approved budget and pays. Draw 16 funds on September 18, 2026.
3. The loan is watched between drawsSite reports, schedule updates, change orders, letters and leasing reports are read against the budget, the reserve and the dates. This is where the $613,000 shortfall is found in October, or found at the February draw.
4. The building is finished and leasedConstruction ends, retainage is paid out, tenants move in, and the reserve hands the interest over to the rent.
5. The loan is repaid or extendedA permanent lender or a sale pays it off at maturity, April 14, 2028, or the bank tests whether the loan qualifies for an extension.

Step 3 is the subject of this guide. Processing one draw (step 2) has its own guide. The people, companies and figures in this example are fictional.

Four surprises in a construction loan that passes its draws

In balance, cost to complete, interest reserve, stabilization

Thirteen terms are defined in the one-page summary.

The six measures a construction lender watches between draws

In shortEvery construction loan can be read on six measures: progress against plan, cost to complete, contingency left, the in-balance position at completion, the interest reserve's runway, and the lease-up against plan. Each document that arrives moves one or more of them. Monitoring is keeping all six current for every loan, so that the loans needing a decision rise to the top.

The OCC's handbook names all six: costs-to-complete and loan funds remaining, construction deadlines, change orders "tracked and reflected in the project's budget", monthly leasing reports with rent rolls, and interest reserves that should last "through the project's anticipated completion and lease-up, sale, or occupancy".1

Which document moves which measure

The grid shows why monitoring is hard to do by hand. A single schedule update touches five measures, and the effect on the reserve depends on the lease-up, which depends on the market. A spreadsheet that holds the six measures for one loan is manageable. Thirty loans, each with five or six documents a month, is a stream of 150 to 180 documents, and the one that matters can sit in an inbox for weeks.

What examiners expect of construction loan administration, as of October 2026

In shortNo regulation prescribes a monitoring method. The examiners' handbooks describe what sound administration looks like, and the 2023 interagency workout statement explains how examiners classify a loan whose reserve keeps it current while the project stalls. In 2026 the model-risk guidance was replaced and the third-party guidance was proposed for replacement; the construction texts themselves did not change.

How to tell whether a construction loan is in balance, today and at completion

In shortA loan is in balance when the money still to come covers the cost still to pay. The usual draw test measures that against the approved budget. A forecast test adds what the budget does not hold yet: pending change orders, claims, interest past the reserve, and anything else the documents say is coming. The difference between the two tests is the warning.

Most construction loan agreements carry a balancing clause. If the bank decides the loan is out of balance, the borrower must deposit the difference, usually within a set number of days, before the bank funds more. The clause is only as useful as the bank's view of the cost to complete. If that view is the approved budget, the clause can fire only after a change order is approved or a claim is settled, which may be months after the document that announced it.

The Harrow Yard test, two ways

Two choices sit inside that arithmetic, and a bank's credit policy should make them once for every loan. The first is whether to count a change order or claim before it is approved, and at what amount. Counting it at the claimed amount is conservative; a claim may settle for less.

The second choice is the finish line for interest: substantial completion, completion plus a fixed number of months, or a leasing level. The interest that matters is the interest until the rent can pay it, which is why the forecast above runs to 90% occupancy.

Contingency and retainage: the two cushions inside a construction budget

In shortContingency is money in the budget for the costs nobody priced; retainage is money held back from each payment until the work is finished. Contingency gets spent as change orders arrive, so a report that ignores pending changes overstates what is left. Retainage is money already earned and still owed, so the cost to complete must carry it to the end.

How big a contingency should be, and how fast it goes

The OCC says contingency allowances "vary based on the project's size or complexity but usually range between 5 and 10 percent of the overall budget".1 Common uses are rising material prices or a redesign. The handbook also says who pays for a bad estimate: cost overruns that come from "poor projections or management" would "ordinarily be covered by the borrower rather than by a draw-down on the loan amount budgeted for contingencies".1

Judge a contingency as a share of the work still to build, because the risk sits in what is left. A cushion that looked ample against the original budget can be thin against the remaining work after a year of change orders.

At $1,026,000, Harrow Yard's contingency is 4.9% of the hard cost still to build, just under the bank's 5% minimum, and three pending change orders total more than all of it. Contingency absorbs each surprise quietly until it runs out, so a report that shows only what "remains" hides the pending column that will use it.

Retainage: earned, held back, still owed

On a commercial progress-payment plan the bank "normally retains, or holds back, 10 to 20 percent of each payment to cover project cost overruns or outstanding bills from suppliers or subcontractors", and pays the holdback with the final draw after lien releases, a final inspection and a certificate of occupancy.1 Contracts between owner and contractor usually hold back a share of each payment too.

For monitoring, retainage matters in two ways. It is part of the cost to complete even when the work is done, so a budget line that looks finished can still owe money. And it comes due in a lump at the end, when the interest reserve is lowest. The Harrow Yard forecast pays 90% of the remaining contract cost as work goes in and the last 10% in the month after completion.

Reading a construction S-curve: planned progress against inspected progress

In shortAn S-curve plots the share of work in place, month by month, against the share the schedule planned. It starts slow, climbs steeply through the structure and services, and flattens during finishes, which gives it its S shape. The gap between the two lines is late work, and its dollar value is the money the schedule expected to spend by now and did not. The critical path tells you which late work moves the finish date.

Read the gap three ways. Its size says how much work is late. Its trend says whether the job is catching up or falling further behind. Its make-up says why, and whether more crews can recover it.

The critical path and the outside date

The critical path is the chain of tasks in which any delay moves the finish. At Harrow Yard it runs through the switchgear (the main electrical equipment), then permanent power, then the elevator inspection, then the temporary certificate of occupancy. The consultant's note on site report 17 says the revised March 26, 2027 completion "is achievable only if the switchgear date holds".

Most loan agreements also set an outside completion date, after which failure to finish is a default. Harrow Yard's is June 30, 2027, which leaves 96 days of margin after the revised date.

Long lead times turn a procurement date into a completion date. A schedule update that shows switchgear "not released for fabrication" in October tells a reader with these numbers in mind more than the percent complete does.

KPMG's 2015 survey also found that 31% of projects came within 10% of budget.4 The survey covers large capital projects worldwide, including energy and public-sector projects. Cost estimates show the same lean: in a study of 258 transport projects worth $90 billion, costs were underestimated in almost 9 out of 10, and actual costs averaged 28% above the estimate.11 Use both as a reminder that delay and overrun are the base case, and measure your own book: how many of your construction loans finished on their baseline date and budget?

How an interest reserve runs out, and how to project the month it hits zero

In shortAn interest reserve pays the loan's interest from the loan itself until the property can. Its runway depends on four things that all move during construction: the outstanding balance, the interest rate, the completion date and the lease-up pace. Project it month by month to the date the property must stabilize, and the month it hits zero, and the interest left unpaid after that, become numbers you can act on.

The OCC's handbook describes the reserve plainly: "An appropriate interest reserve provides sufficient funds to pay interest through the project's anticipated completion and lease-up, sale, or occupancy." It then warns that "The presence of an interest reserve may not accurately reflect a borrower's ability to pay", that badly run reserves "can mask a poorly performing project", and that they "have been a major contributor to banks' losses in ADC lending".1

The outstanding balance grows with every draw, so interest rises month by month through construction and peaks when the loan is fully drawn, which is usually just when the building opens and earns least. Net operating income then starts to pay part of the interest as units lease. During lease-up, the OCC says, "any cash flow from the project is ordinarily applied to pay interest before interest reserves are applied".1

What moves the zero

Because the reserve's runway is a product of several assumptions, a single forecast is less useful than the forecast with its sensitivities beside it. In the Harrow Yard example, each assumption moves the run-out date and the shortfall:

The middle case is the forecast because three comparable buildings nearby are leasing at an average of 22 a month; the closing plan assumed 26. Choosing the assumption is the credit judgment. Showing what happens under the others is what makes the judgment reviewable.

Lease-up, stabilization and the extension test: where the loan's dates collide

In shortA construction loan is usually repaid by a permanent loan or a sale once the property stabilizes. That gives every loan three dates to keep apart: completion, stabilization and maturity. Slow leasing pushes stabilization toward maturity, and an extension then depends on tests the property may not pass. In 2026 the apartment supply wave of 2022 to 2024 is still leasing up.

Why lease-up is slower in 2026

Units under construction in buildings of five or more peaked at 1,001,000 in July 2023 and stood at 677,000 in September 2026.14 The OCC's Spring 2026 risk report notes "continuing rental rate declines in the Sun Belt, driven by the substantial supply wave of 2022-24", while describing demand as steady.15 For a lender, the practical effect is longer lease-ups and larger concessions, both of which draw on the reserve.

Three dates, kept apart

Harrow Yard's dates, side by side

The extension test, worked

Harrow Yard's first extension needs, among other things, a debt yield of at least 8.0%: net operating income divided by the loan amount. At 95% occupancy the forecast debt yield is 7.3%, so the test is already "close" fifteen months before it would be run. That is a separate warning from the in-balance shortfall, and it points at the exit: a permanent lender will run a similar test.

MBA reports that $875 billion, 17% of the $5.0 trillion of commercial and multifamily mortgages outstanding, was scheduled to mature in 2026, including $396 billion serviced by depositories.16 Construction loans finishing into that market compete for the same take-out capital.

Ten ways a construction loan slips between draws without anyone seeing it

In shortMost construction losses start as a document that arrived and was not read against the loan: a change order left out of the budget, a schedule update filed without a reserve projection, a leasing report nobody compared with the pro forma. The examiners' handbooks list the same warning signs; the hard part is noticing them while they are still small.

The examiners' own warning lists

The OCC lists warning indicators that include "slower absorption of space than anticipated", "construction budget overruns, changes to construction plans", "draw requests ahead of schedule for work yet to be completed", "construction delays or other unanticipated events that could lead to cost overruns" and "interest reserves that have been repacked".1 The FDIC's manual adds "Rent concessions or sales discounts resulting in cash flow below the level projected in the original appraisal" and "Changes in concept or plan".2 Each is something a document says before a payment shows it.

When a construction loan should move to the watch list, and what failed banks show

In shortConstruction delays and slower leasing are, in the OCC's words, potential weaknesses that fit Special Mention. When they start to threaten repayment, the loan becomes substandard. The banks that failed after 2008 often let interest reserves keep troubled construction loans current until the reserve was gone. Construction loan delinquency is low in 2026 but has doubled since 2022.

Special Mention, in the handbook's words

The handbook also says a troubled loan can be masked "when interest reserves continue to be applied to interest payments, keeping the loan current even though expected leases or sales have not occurred".1 In the Harrow Yard example, the loan moves from rating 4 to 5, Special Mention, ten months before its reserve would run dry, with the forecast, its sources and the actions recorded with the change.

What the failed banks showed

The FDIC's inspector general reviewed the bank failures of 2008 to 2010, when failures rose from 25 in 2008 to 140 in 2009. Concentrations in commercial real estate and construction loans with weak risk management "played a role in practically every failure that was the subject of" a material loss review.

Banks "frequently relied heavily on interest reserves, which can mask loans that would otherwise be reported as delinquent", some replenished reserves "when payment was in doubt", and some "did not always track, monitor, and report on the use of interest reserves".3 At one group of six failed banks in Georgia, examiners found that from November 2007 borrowers kept using interest reserves "despite problems with the project being financed (e.g., a delay or total cessation of the project)", so loans were not reported as delinquent "until all interest reserves were depleted".17

Read these rates with the masking problem in mind. A construction loan with a funded reserve is current by construction. The delinquency rate measures the loans whose reserves have already run out; the loans whose reserves will run out next year are in the "current" column today.

Construction lending in 2026: banks ease standards while input prices climb 11.2%

In shortUS banks hold about $455 billion of construction and land development loans, down from a 2024 peak. By July 2026 slightly more banks were easing construction standards than tightening them, after a sharp tightening in 2023. Input prices rose 11.2% in the year to September 2026, so budgets written in 2024 and 2025 carry contingencies under strain.

The FDIC counts $453.5 billion of construction and development loans at insured institutions on June 30, 2026, down 3.4% in a year, of which community banks hold $152.8 billion. Community banks also report $83.1 billion of unfunded commitments for commercial and other construction: money promised that will be drawn, and monitored, as the buildings go up.21

The Associated Builders and Contractors' chief economist called the September 2026 figure "the largest year-over-year increase in nearly four years", driven partly by fuel, and said "prices for tariffed materials like iron, copper and other metal products continue to rise rapidly".25 A budget's contingency was sized for the prices of the year it was written.

Rates moved the other way: SOFR, the overnight rate behind the Term SOFR benchmark that floating construction loans often use, was 4.40% on January 2, 2025 and 3.94% on October 29, 2026,26 which slows the burn of reserves on loans that closed at higher rates.

What software can forecast on a construction loan, and what stays with people

In shortSoftware can read the monthly documents as they land, restate progress against plan, add pending items to the cost to complete, project the reserve month by month, run the tests and draft the notice and the report. It cannot see the site, judge a change order or decide a rating. Supervisors expect AI in banking to be used with guardrails and human accountability, and the 2026 model guidance leaves generative AI to each bank's own governance.

The OCC and SR 26-2 on AI for a construction book

NIST's AI Risk Management Framework, published January 26, 2023 with a generative AI profile on July 26, 2024, organizes the work into four functions: govern, map, measure and manage; NIST says version 1.0 is being revised in 2026.27 For a monitoring tool, "measure" has a concrete meaning: replay last year's loans and count how many months earlier the tool would have flagged each problem, and how many false alarms it raised on loans that finished fine.

Percent complete, change orders and ratings stay with people

• The consultant's percent complete stays the consultant's. Software compares it with plan; it should never adjust it.
• A change order is approved or rejected by people under the loan agreement. A forecast that counts it pending makes no decision about it.
• Ratings, notices and conversations with the sponsor stay with named people. A shortfall forecast is a reason to talk to the borrower, made by the person who owns the relationship.
• The forecast is only as good as its assumptions. The lease-up pace and the rate path are credit judgments that someone should own and sign.

Who monitors a construction book today, and where each loan's hours go

In shortAn administrator runs the draws and keeps the budget, a consultant inspects, a portfolio manager or credit officer keeps the forecast and recommends ratings, a lending officer talks to the sponsor, and the chief credit officer takes the book to committee. Most of the monthly hours go into re-keying documents into spreadsheets and rebuilding projections, which is why many banks re-forecast a loan only at the draw.

The monthly cycle and its hand-offs

Where a loan's monthly hours go

At that estimate, a 31-loan book takes about 350 hours a month, roughly two people's working time. Schedules themselves arrive late: in a 2025 survey by a scheduling software vendor, only one in four teams reported updating their schedules on time.28 Banks without those people re-forecast at the draw, and the draw is when the budget is least likely to hold the bad news.

Harrow Yard after Draw 16: a reserve that runs dry four months early, and the balancing notice it leads to

In shortThis is the example from the top of the page, inside the product. Six agents read the five documents that arrived after Draw 16, re-forecast the loan in a little over a minute, and draft four actions. Owen Pryce, the portfolio manager, reviews the forecast and its sources, approves the actions and signs the notice. Lydia Fernsby, the chief credit officer, approves the rating change. Nothing reaches the borrower until the lending officer sends it.

1

Thirty-one loans, ranked by how far each reserve falls short

Monday morning, October 12. Owen opens the S-curves. Across the top, his 31 construction loans are ranked by how far the interest reserve falls short of each project's finish, and Harrow Yard is first: "Reserve $0 Aug '27 · 4 mo before the finish". Its S-curve shows the certified line bent below the plan, 61.4% against 68.0%, the gap shaded in red.

Below the curve, on the same time axis, the reserve and the contingency burn down to the finish, solid to today and dotted after. On the right, the gap is broken into trades: drywall on Levels 3 to 5 is $1.50 million behind, the main switchgear $0.74 million.

Re-forecast from the five documents, step by step

The loan monitor lists the signals since Draw 16, each with a link to its page: site report 17, schedule update rev 9, pending change orders 11 to 13, the contractor's letter of October 8 and the week 10 leasing report. The forecast run shows what each agent read and found, and how long it took: 1 minute 12 seconds in all.

Four numbers sit above it: in balance today at $25.7 million, forecast $613,000 short at completion, the reserve dry in August 2027, and 61.4% complete against 68.0%.

3

The money, burning down to the finish

The lower panel of the S-curve is the warning in one picture. The interest reserve, $1,835,000 today, hits zero in August 2027. The finish line, 90% leased, is December 2027. The four months between are hatched: $210,000 of interest with nothing to pay it. The contingency runs out in March 2027 and ends $403,000 over once the delay claim is counted.

"Short $613,000 at the finish" sits on the finish line, while today's draw test still passes.

Why the draw test cannot see it

The cost-to-complete screen lays the budget out line by line: budget, disbursed, remaining, change and forecast. The bridge on the right walks from the $25.7 million left in the loan to the $26.3 million forecast cost to complete: pending change orders up $1,148,000, the contingency that absorbs them down $1,026,000, the delay claim up $281,000, interest to 90% occupancy up $210,000.

The panel below shows each pending item against the contingency. The largest, $612,000 for switchgear and copper feeders, follows a supplier letter citing metals tariffs.

Four actions approved, the notice signed, the rating changed

The risk and action drafter recommends four actions: a balancing notice to the sponsor for $613,000 under section 7.3 of the loan agreement; a recovery schedule from the contractor by October 23, with the delay claim held; the watch list at risk rating 5, Special Mention; and an extension test set for January 14, 2028. Owen approves and signs, with the meaning of his signature recorded. Lydia Fernsby approves the rating.

The decision panel records the context: 24 days before Draw 17 on November 5, ten months before the reserve would run dry. The signed notice waits for Marcus Delaney, the lending officer, to send it.

The loan, the bank and every person are fictional. The ten months and 24 days are this example's figures. The solution's design target is every construction loan re-forecast within an hour of a new signal, to be measured on your own book.

A slower lease-up tried, the schedule against its baseline, the risk board and the monthly committee report

In shortOne loan is the story. These screens show the rest: trying a slower lease-up on the forecast, the schedule against its baseline, the gap by trade with the consultant's notes, the reserve month by month, the risk board for the whole book, the tests, the signature, the monthly committee report and the settings that hold the bank's credit policy.

Agents re-forecast; the portfolio manager signs notices and the chief credit officer changes ratings

In shortEach agent has one job and limits it does not cross. None of them changes a loan term, a rate, a rating or a consultant's percentage, approves a change order, declares a default or contacts the borrower. The portfolio manager approves actions and signs notices; a rating change needs the chief credit officer; only the lending officer talks to the sponsor.

Every agent step, upload and approval is on the loan's activity trail with who, what and when. The 0 to 100 risk score ranks loans for attention; the bank's risk rating (here 4 to 5, Special Mention) is a separate grade that only the chief credit officer changes.

From consultant site reports and draw history to an S-curve, a reserve runway and a monthly portfolio report

In shortThe solution reads the documents your loans already produce, applies your credit policy as settings, and leaves behind, for every loan, an S-curve to the finish, a cost to complete with pending items, a reserve projection with every assumption, tests with their figures, drafted actions and notices, and the monthly portfolio report. Your loan system stays the system of record.

What a shortfall found at the draw costs you, compared with one found months earlier

In shortThe cost of late monitoring is mostly the cost of options lost. A shortfall found ten months out is a deposit request; the same shortfall found at the last draws is a negotiation with a sponsor who has fewer reasons to pay, a reserve top-up the examiners will question, or an extension. No public study measures the difference, so your own loans are the evidence.

What earlier warnings and released hours could return for your construction book

In shortPut in your own numbers. The calculator values two things: the hours your team spends re-keying and re-forecasting each loan each month, and the problem loans you would catch a quarter or more earlier. Every default is an assumption marked illustrative; replace each with your own.

Monitoring hours, months of runway and reserves that never surprise

Your hours and earlier warnings across your construction loans

A bank with 30 construction loans and a few problem loans a year sits well above these lines. A bank with eight small, pre-leased loans and one administrator probably does not, and should say so before buying anything.

What to ask a construction loan monitoring software vendor: seventeen questions on forecasts, reserves and evidence

In shortAsk every vendor the same questions, us included. The answers show whether the tool reports what has been drawn or forecasts what is coming, whether its numbers can be traced to documents, whose policy it applies, and how you would test it on your own loans.

We found no published independent test of any construction monitoring vendor's forecasts, as of October 2026. A replay of your own past loans is the fairest comparison, and the same replay measures your current process.

A twelve-week pilot that replays last year's construction loans before you commit

In shortMeasure your history first, replay it, then run in parallel on the live book and decide with three numbers. None of these steps commits you to a vendor.

1. List last year's problems: balancing notices, reserve top-ups, extensions and downgrades on construction loans, with the date each problem first appeared in a document.
2. Write the forecast rules down: what counts in the cost to complete, the date the reserve must reach, the contingency minimum, the thresholds.
3. Replay 15 to 25 loans with their documents in the order they arrived, including loans that finished well.
4. Run in parallel on the live book for six weeks, with your people approving every action.
5. Decide with three numbers: months of earlier warning, false alarms, and staff hours per loan per month.
