> How a bank statement construction loan funds a build for self-employed owners: draw schedules, reserves, builder review and when to wait for completion.
A bank statement construction loan pays for a new home in stages while qualifying a self-employed owner on 12 or 24 months of deposits rather than tax returns. The lender releases money in draws as the builder finishes work, charges interest on what has been drawn, and then converts or refinances the balance into a permanent mortgage.

## What is a bank statement construction loan?

A bank statement construction loan is a non-QM loan that funds land and building costs in stages, using deposit history as the income evidence. A purchase loan pays one seller one price at closing. A construction loan pays a builder many times over several months, so the lender is underwriting a project as well as a borrower.

### Two loans in one file

Most construction financing has two phases. The construction phase lasts while the house is being built, and payments during it are usually interest only on the amount drawn so far. The permanent phase is a regular mortgage that begins once the home is complete.

Lenders package those phases in one of two ways:

- **One-time close.** The borrower signs once. The construction phase rolls into the permanent mortgage when the certificate of occupancy is issued, without a second closing.
- **Two-time close.** The borrower takes a short construction loan, then closes a separate permanent loan at the end. That second loan is underwritten again, with fresh statements and a new rate.

Fewer lenders offer construction financing on bank statements than offer a bank statement purchase loan, and the ones that do often add tighter limits. A broker should expect a short list.

### What the deposit income has to support

The income test looks at the full payment the owner will carry once the home is finished, not the smaller interest payment during the build. The lender averages eligible deposits, applies an expense factor (a percentage taken off to cover business costs) and compares the result with that future payment. The baseline rules on credit, history and ratios match the ones in [the full checklist of bank statement loan requirements](/blog/bank-statement-loan-requirements), with construction overlays on top.

### A federal rule that treats the build differently

Federal ability-to-repay rules under Regulation Z carve out part of the construction phase. The text of [12 CFR 1026.43 at Cornell's Legal Information Institute](https://www.law.cornell.edu/cfr/text/12/1026.43) exempts "a construction phase of 12 months or less of a construction-to-permanent loan" from the paragraphs that set the repayment and qualified mortgage tests. The permanent phase is still covered, so the income work cannot be skipped.

## Draw schedules on a bank statement construction loan

A draw schedule is the list of stages at which the lender releases money to the builder, with a dollar amount or a percentage of the budget tied to each stage. The lender pays a draw only after an inspector confirms the work for that stage is done, so cash follows progress instead of running ahead of it.

### A worked draw schedule

The table below is an example for a home with a $500,000 construction budget. The stages and percentages are illustrative; every lender and builder contract sets its own.

| Draw | Stage confirmed by inspection | Share of budget | Example amount | Cumulative drawn |
| --- | --- | --- | --- | --- |
| 1 | Permits, site work, foundation | 15% | $75,000 | $75,000 |
| 2 | Framing and roof | 25% | $125,000 | $200,000 |
| 3 | Mechanical, electrical, plumbing rough-in | 20% | $100,000 | $300,000 |
| 4 | Drywall, windows, exterior finish | 20% | $100,000 | $400,000 |
| 5 | Interior finish and fixtures | 15% | $75,000 | $475,000 |
| 6 | Final inspection and occupancy | 5% | $25,000 | $500,000 |

### What the interest looks like during the build

Interest accrues only on the cumulative amount drawn. Using an example construction rate of 9 percent, the monthly interest after draw 2 is about $1,500 on $200,000 drawn. After draw 4 it is about $3,000 on $400,000. The owner pays these amounts from personal funds while often also paying rent or a current mortgage. That double housing cost is the main cash strain on a build.

### Retainage and the last draw

Some contracts hold back a part of each draw, called retainage, until the job is finished. The final draw often waits for the occupancy certificate and a lien release from the builder. Delays at this stage are common, because a single failed inspection item holds the payment.

## Reserves and contingency for a self-employed construction borrower

Reserves are cash the borrower must still hold after closing, counted in months of the future housing payment. A contingency is a separate amount set aside inside or beside the budget to cover cost overruns. A construction file usually needs both, and a self-employed owner needs to plan for them before the first draw.

### Why reserves run higher on a build

A finished house can be appraised and sold. A half-built one is harder to value and harder to sell. Lenders cover that risk by asking the borrower to keep more cash on hand than a purchase would need. They also want to see that the owner can pay interest during the build without pulling money out of the business that produces the qualifying deposits.

### Contingency sizing

A contingency is often set as a percentage of hard costs, the money spent on labor and materials. Lumber price swings, a change order the owner requests and a soil problem found during excavation all draw on it. If the contingency runs out, the owner pays the gap in cash before the next draw is released.

### Where the cash comes from

The down payment, the reserves and the contingency all need a documented source. Funds that move from a business account into a personal account need a clear trail, and a large deposit in the last few months will draw a question. The same deposit sourcing a lender applies to a purchase applies here. For an owner trying to keep the cash requirement low, [the comparison of 5 and 10 percent down payment options](/blog/bank-statement-loan-5-down-payment-options) explains which programs allow smaller equity and what that costs. Low down payment options are rarer on construction loans than on purchases.

### A checklist before the first draw

1. Confirm the down payment or land equity is documented and seasoned.
2. Confirm reserves remain after closing, in the months the lender requires.
3. Confirm the contingency is funded and who can approve its use.
4. Budget the interest payments for the full build plus a delay margin.
5. Confirm the business can keep its normal deposit pattern while the owner pays for the build.

## Builder approval and plan review in a construction file

Builder approval is the lender's check that the contractor is licensed, insured, financially sound and experienced with similar homes. Plan review is the check that the plans, specifications and budget add up to the appraised value. A lender can decline a strong borrower because of a weak builder, so this review starts early.

### What lenders usually collect from the builder

- A copy of the state contractor license and proof of liability insurance.
- A signed construction contract with a fixed price or a clear cost-plus structure.
- A line-item budget that ties to the draw schedule.
- References or a list of recent completed homes.
- Lien waiver forms the builder will sign at each draw.

### Owner-builders

A self-employed borrower who works in construction may want to act as their own general contractor. Many lenders do not allow it, and the ones that do apply stricter rules on experience and reserves. If the borrower's own company is the builder, the lender may also look at whether construction draws are flowing back into the same business account used for qualifying income. That is a reason to keep the build funds and the business deposits in separate accounts.

### The as-completed appraisal

The appraiser values the home as if it were finished, using the plans and the budget. If the as-completed value comes in below the total project cost, the loan amount drops or the owner adds cash. Upgrades that do not raise market value, such as a custom feature most buyers would not pay for, are where this gap tends to open.

## Does deposit income get checked again before the construction loan converts?

Deposit income is often checked again before conversion, depending on how the loan is structured. A two-time close always re-underwrites the permanent loan, with new statements. A one-time close may lock the income at the start, though some lenders still ask for updated statements or a verbal check of self-employment before the permanent phase begins.

### Why a long build reopens the income question

A build that runs a year or more means the original statements are old by the end. If the business slowed during the build, perhaps because the owner spent time managing the project, the new average may be lower. A falling trend on a re-underwrite can shrink the permanent loan or force a larger cash payment at the end.

### What to keep ready

Keep every monthly statement for the qualifying accounts as it arrives during the build. Note any large deposit with its source while it is fresh, because explaining a deposit from ten months ago is harder. A broker who tracks the average as the months come in sees a problem before the lender does. TrueBankFlow lines up each month's deposits next to the earlier ones and flags large or out-of-pattern items with the statement line, which makes a mid-build check quicker to run.

### Agency comparisons

A borrower who sees agency guidelines quoted online may expect the same document rules. The agencies set different statement requirements, which [the Fannie Mae bank statement requirements guide](/blog/fannie-mae-bank-statement-requirements) lays out, and an FHA construction loan uses tax-return income. The reasons FHA will not count deposits as income are covered in [why FHA has no bank statement loan](/blog/fha-bank-statement-loan).

## When to finish the build first and use a bank statement purchase loan

Finishing the build with other money and then using a bank statement purchase or refinance loan can beat a construction loan when the owner has enough cash or land equity, when the builder will finance the build, or when the project is small. A finished home is easier to appraise, and the loan menu is much wider.

### Signs a construction loan is the wrong tool

- **The owner can fund the build.** If savings or a line of credit cover construction, a cash-out refinance on the finished home may cost less in fees and interest than a year of construction draws.
- **The builder offers financing.** Some builders carry the construction cost and sell the finished home. The owner then needs only a purchase loan.
- **The business is in a slow period.** A falling deposit trend at application, and a re-underwrite at the end, can stack against the borrower twice.
- **The timeline is uncertain.** Permits, materials and labor delays extend the build, the interest bill and the age of the statements.

### A quick test

Estimate the total construction-phase interest using the draw schedule, add the extra fees and the higher reserves, and compare that with the cost of a short-term personal funding source followed by a standard bank statement loan. If the gap is small, the simpler path has fewer points where the file can fail.
