> How the ability to repay rule applies to bank statement mortgages: the eight factors, reasonable income verification and the records lenders keep.
The ability to repay rule requires a mortgage creditor to make a reasonable, good faith determination, at or before closing, that the borrower can repay. For a bank statement mortgage, that means weighing eight factors, verifying income with third-party records such as the bank statements themselves, and keeping the evidence for three years after consummation.

## Which mortgages fall under the ability to repay rule?

The ability to repay rule covers consumer credit secured by a dwelling. It sits in Regulation Z at section 1026.43 and reaches most closed-end home loans for self-employed borrowers, bank statement programs included. It does not apply to home equity lines of credit, loans secured by a timeshare, or credit made mainly for a business purpose.

The [Cornell LII text of 12 CFR 1026.43](https://www.law.cornell.edu/cfr/text/12/1026.43) lists further exemptions from the core repayment duties. They include reverse mortgages, a temporary or bridge loan with a term of 12 months or less, and the construction phase of 12 months or less of a construction-to-permanent loan. Certain housing finance agency programs and some nonprofit and community development lenders are also carved out.

Business purpose is the exemption that matters most on deposit-based files. A self-employed owner buying a home to live in is taking consumer credit, even when the income comes from a business account. An investor buying a rental through an LLC is usually taking business credit, which Regulation Z does not reach. That second file follows different rules. For business lenders and merchant cash advance funders, the closest equivalent duty is often a state disclosure law, which the guide to [commercial financing disclosure laws for MCA funders](/blog/commercial-financing-disclosure-laws) covers.

The rule also sets a timing point. The determination must be made at or before consummation. An underwriter who approves a file on statements that end four months before closing has to consider whether anything changed in between.

## The eight ability to repay factors on a self-employed borrower's file

The ability to repay rule names eight factors the creditor must consider, unless a safe harbor or special provision says otherwise. Each factor needs a source in the file. On a bank statement mortgage, the statements answer the income factor, the credit report answers several others, and the loan terms answer the payment factors.

The table below lists the factors in the order section 1026.43(c)(2) gives them, with the record that usually answers each on a self-employed borrower's file. The record column is an example of common practice, not a rule.

| Factor in 1026.43(c)(2) | Where it usually comes from on a bank statement file |
| --- | --- |
| (i) Current or reasonably expected income or assets, other than the home's value | 12 or 24 months of business or personal statements, an expense factor, any asset statements |
| (ii) Current employment status, if employment income is relied on | Business license, CPA letter or a check that the business still operates |
| (iii) Monthly payment on the loan | The note terms, calculated as the rule requires |
| (iv) Monthly payment on any simultaneous loan | A second lien or HELOC closing at the same time |
| (v) Monthly payment for mortgage-related obligations | Property tax, homeowners insurance, HOA dues |
| (vi) Current debt obligations, alimony and child support | Credit report, divorce decree, statements showing recurring payments |
| (vii) Debt-to-income ratio or residual income | Calculated from the figures above |
| (viii) Credit history | Credit report |

Two factors deserve extra attention on statement files. On a self-employed file, lenders usually treat the employment factor as a check that the business exists and continues, since there is no employer to call. And the debt factor can pick up obligations the credit report misses. A recurring transfer to a private lender, visible every month on the statement, is a debt even if no bureau reports it. Section 1026.43(c)(3) does let a creditor skip separate verification of a debt the borrower lists on the application that the credit report does not show.

## Can bank statements verify income under the ability to repay rule?

Bank statements can verify income under the ability to repay rule. Section 1026.43(c)(4) lists "financial institution records" among the third-party records a creditor may use, alongside tax returns, W-2s and payroll statements. What the rule then asks is whether the income figure drawn from those records is reasonable.

The rule is written about records, not about loan programs. It does not name bank statement mortgages, and it does not set an expense factor or a lookback length. Those come from investor guidelines and the lender's own policy. The rule only requires that the creditor verify the income or assets it relies on, using reasonably reliable third-party records, and that the overall determination be reasonable and made in good faith.

Reasonable is where the work sits. A year of deposits into a business account is gross receipts. It includes sales tax collected, owner transfers, loan proceeds and refunds. An income figure built on that total, with no adjustment, is hard to call reasonable. The usual adjustments are to remove deposits that are not business revenue, then apply an expense factor or a third-party prepared profit and loss figure to reach net income.

Statements also have to be the borrower's own records. A creditor should check that the account holder name matches the borrower or the borrower's business, and that the pages are complete for each month. A missing page is a gap in the verification.

The source of the statements is changing too. Consumer-permissioned account data, pulled directly from a bank with the borrower's consent, is another form of financial institution record. The guide to the [section 1033 rule on open banking data](/blog/section-1033-rule) explains how that data reaches lenders and what limits apply.

## Ability to repay worksheet for a 12-month bank statement file

An ability to repay worksheet shows each factor, the figure used and the record behind it, so a reviewer can follow the determination without redoing it. The example below is for a self-employed borrower qualifying on 12 months of business account statements. Every number is an example for illustration only.

### Income, from the statements

| Line | Example figure | Record |
| --- | --- | --- |
| Total deposits, 12 months | $480,000 | Business checking statements, months 1 to 12 |
| Less transfers from the borrower's own savings | $28,000 | Matching debits on the savings statements |
| Less one SBA loan disbursement | $8,000 | Loan agreement and the deposit line |
| Eligible deposits | $444,000 | Calculated |
| Expense factor applied (example: 50%) | $222,000 | Lender program guide |
| Monthly qualifying income | $18,500 | $222,000 divided by 12 |

### Payments and debts

| Line | Example monthly figure | Record |
| --- | --- | --- |
| Principal and interest on the new loan | $3,800 | Note terms |
| Property tax, insurance and HOA | $1,100 | Tax bill, insurance quote, HOA statement |
| Simultaneous second lien | $0 | None closing |
| Auto loan and credit cards | $950 | Credit report |
| Total monthly obligations | $5,850 | Calculated |

### Result

Debt-to-income is $5,850 divided by $18,500, about 31.6%. Residual income is $12,650 a month. The underwriter adds two notes: the deposit trend across the 12 months is flat to rising, and the business license was confirmed active within the last 30 days.

The worksheet is short, but every row points to a page. That traceability is the point. When a figure in the income table links back to the statement lines behind it, as TrueBankFlow's totals do, the reviewer can check the transfer exclusions in seconds instead of rebuilding them.

Brokers can prepare most of this before the file goes in. The [broker loan submission checklist](/blog/broker-loan-submission-checklist) lists the documents a lender expects in the package, so the worksheet's record column fills in without a second request.

## How long do ability to repay records stay in the loan file?

Ability to repay records stay in the file for three years after consummation. That is longer than Regulation Z's general two-year retention period, and the clock starts at closing rather than at the date a disclosure was due. The records to keep are the evidence of compliance: the income verification, the debt records and the determination itself.

The [CFPB's text of Regulation Z section 1026.25](https://www.consumerfinance.gov/rules-policy/regulations/1026/25/) sets both periods. The general rule in 1026.25(a) runs two years from the date disclosures were required or action was required. Section 1026.25(c)(3) sets three years from consummation for evidence of compliance with section 1026.43. An enforcing agency can require longer.

For a bank statement file, evidence of compliance means more than the final income number. Keep the statements relied on, the list of excluded deposits with the reason for each, the expense factor and its source, and the worksheet. A determination that shows only "income: $18,500" proves little three years later, when the underwriter who wrote it may have left.

Other rules can push the period longer. A file that is also subject to investor repurchase terms, or that becomes part of a dispute, should follow the longest period that applies.

## Ability to repay gaps that weaken a deposit-based income figure

Ability to repay gaps on deposit-based files usually come from treating gross deposits as income. The rule does not prescribe a method, so a creditor that skips adjustments has no formula to blame. The determination is judged on whether it was reasonable, and an income figure inflated by transfers or loan proceeds is not.

### Counting every credit as revenue

Transfers between the borrower's own accounts show up as deposits on each statement. So do loan disbursements, insurance refunds and cash from selling equipment. None of them is income from the business. Each needs a decision and a note, and the notes belong in the file.

### Ignoring the trend

A 12-month average can hide a business in decline. If the last three months run 40% below the first nine, the average overstates what the borrower brings in now. The rule asks about current or reasonably expected income, so the trend is part of the factor, not a side detail.

### Relying on a borrower-prepared summary alone

A profit and loss statement the borrower wrote is not a third-party record. It can explain the statements, but it cannot replace them.

### Letting the file go stale

Statements that end months before closing leave a gap between the determination and consummation. A short refresh, such as the latest month's statement, closes it.

### Skipping debts that live only on the statements

Recurring payments to a private lender, an equipment lease or a support order that never reached a bureau still count under factor (vi). Reading the debit side of the statements, not just the deposits, is how they surface.
