# Bank Statement Lenders: How Brokers Compare Them - Author: TrueBankFlow (https://truebankflow.com) - Published: 2026-10-16 - Category: Bank statement loan programs - Canonical: https://truebankflow.com/blog/bank-statement-lenders-compared > Compare bank statement lenders on lookback months, expense factors, account rules and overlays, with a matrix brokers can fill in for each lender. Bank statement lenders differ on the guidelines that set a borrower's income and eligibility: months of statements accepted, the expense factor, accepted account types, minimum score, maximum LTV, reserves and overlays. Compare lenders on those terms, file by file, and send the borrower to the one whose rules return the most income at an acceptable price. ## Which guidelines separate one bank statement lender from another? Seven guidelines do most of the separating: lookback months, expense factor, minimum credit score, maximum loan-to-value, reserves, accepted account types and tolerance for NSF activity. Two lenders can share a program name and still return different incomes and prices for the same borrower, so these seven are what a broker should record. ### Lookback months Lenders accept 12 months, 24 months, or both. A 12 month lookback uses the most recent year, which helps a growing business. A 24 month lookback smooths out a bad quarter but drags in older, lower months. Some lenders let the borrower choose; others set the lookback by loan size or score. The tradeoffs are covered in [12 versus 24 month lookbacks](/blog/12-month-bank-statement-loan-vs-24-months#what-changes-between-a-12-month-bank-statement-loan-and-24-months). ### Expense factor The expense factor is the percentage lenders subtract from eligible deposits to estimate business costs. It may be a fixed number, a number tied to business type, or a lower figure supported by a tax professional's letter. A ten-point difference in the factor moves qualifying income by ten percent of eligible deposits: on $20,000 a month, that is $2,000 of income. How the factor is set is explained in [how an expense factor is set](/blog/bank-statement-loan-expense-factor#what-is-a-bank-statement-loan-expense-factor). ### Credit score, LTV and reserves These three decide whether the file is eligible at all. Minimum scores, maximum LTV by loan purpose and occupancy, and reserve months all come from the lender's matrix. A borrower with a strong score and a large down payment can pass at several lenders. A borrower near a limit passes at few, and the broker should find out which before any statements are collected. The common ranges are laid out in [the full bank statement loan requirements checklist](/blog/bank-statement-loan-requirements). ### Account types and NSF tolerance Some lenders take only business accounts, some only personal, and some allow either. Each also sets a limit for NSF fees and overdrafts in the lookback. A lender that accepts two NSF events in twelve months declines a file with three that another lender approves. ## Lookback and expense factor terms across bank statement lenders Lookback and expense factor terms vary most between lenders, and together they decide the qualifying income. The same deposit history can produce several incomes depending on the months used and the percentage removed. Compare both terms side by side, not one at a time, because a lender strong on one may be weak on the other. ### How the two terms interact A lender with a 12 month lookback and a 50 percent expense factor can return less income than a lender with a 24 month lookback and a 35 percent factor, depending on the deposit trend. When deposits are rising, the shorter lookback adds income. When they are falling, it may subtract. ### Example comparison These lenders are fictional and the numbers are examples only. A borrower has $20,000 a month in eligible deposits over 12 months. | Example lender | Lookback | Expense factor | Qualifying income | | --- | --- | --- | --- | | Lender A | 12 months | 50 percent | $10,000 a month | | Lender B | 24 months | 40 percent | $12,000 a month, if the 24 month average is also $20,000 | | Lender C | 12 months | 30 percent with a tax professional letter | $14,000 a month | The table shows why the factor matters. Lender C returns 40 percent more income than Lender A on the same deposits. If the 24 month average at Lender B is lower, say $17,000, its income falls to $10,200 a month. A broker who checked only the headline factor would have missed that. ### Reading a lender's matrix Lender guidelines come as a rate sheet and a matrix of limits. Read the matrix for the borrower's exact scenario: purchase or refinance, owner-occupied or investment, loan amount, and score tier. A limit stated for one scenario often does not apply to another. When a number is unclear, ask the lender's account executive and write down the answer with the date, because guidelines change. ## How do bank statement lenders treat business versus personal accounts? Bank statement lenders treat the two account types differently: personal statements count nearly all eligible deposits, while business statements carry an expense factor and ownership rules. Some accept only one type, and a few let a borrower use either. Knowing which a lender accepts decides whether the file can go there at all. ### Personal account programs With personal statements, the borrower's deposits are treated as income earned by the borrower. Many lenders count eligible personal deposits at or near 100 percent with no expense factor, but the underwriter must separate business deposits from non-business ones, such as a spouse's pay or a gift. Mixed use makes this review long. Reading mixed accounts is covered in [reading mixed personal and business accounts](/blog/self-employed-bank-statements#why-are-self-employed-bank-statements-harder-to-read). ### Business account programs With business statements, the lender wants to see that the borrower owns the business, usually through an ownership percentage rule, and often asks for a tax professional's letter confirming it. The deposits are company revenue, so the expense factor carries more weight. The borrower's pay from the company may also be checked against what the borrower claims. Details on ownership rules and company-account use are in [using business accounts for a bank statement loan](/blog/business-bank-statement-loan). ### Combining accounts Borrowers with more than one account raise the same questions at every lender: do transfers between the accounts count, and does every account need the full lookback? A lender that allows several accounts usually requires the borrower to list all of them, and to document transfers so that money is not counted twice. Check that rule early when the borrower runs revenue through multiple channels. ## Lender overlays that decline a clean bank statement file An overlay is a lender rule stricter than the published guideline, and overlays decline files that look clean on paper. They tend to concern NSF counts, large deposits, property types, loan sizes and recent credit events. A broker should ask about overlays before submission, since a file that meets the matrix can still fail one. ### Common overlays to ask about - **NSF and overdraft limits.** A set count per lookback, sometimes only for recent months. - **Large deposit rules.** Any deposit over a stated share of monthly income needs a source. - **Property restrictions.** Rural, condo or non-warrantable properties may be capped or excluded. - **Loan size and score pairings.** A high balance may demand a higher score and more reserves. - **Recent credit events.** Seasoning periods after a foreclosure or bankruptcy vary by lender. - **Self-employment history.** Some lenders ask for two full years, even when the guideline text suggests less. ### How to find them Overlays rarely appear on a rate sheet. They come from account executives, lender portals, prior declines and other brokers. Record each one in your matrix the first time it comes up. A decline reason from a past file is worth a line in the notes, because the same overlay will return on the next borrower. ### Reading a decline When a file is declined, ask whether the reason was the borrower's profile or a lender overlay. A profile decline means the borrower may not fit any lender yet. An overlay decline means another lender may take the file as-is, which is why the matrix is worth building. ## Building a bank statement lender matrix for your brokerage A lender matrix is a table with one row per lender and one column per guideline, kept current by the brokerage and checked before each submission. It turns lender knowledge from one broker's memory into a shared tool, and it shortens the choice for every new file. ### The template Copy the columns below into a spreadsheet. The values are examples of how to fill them in. Use the lender's own words and note the date. | Column | What to record | Example entry | | --- | --- | --- | | Lender | Name and account executive | Lender A, J. Rivera | | Months accepted | 12, 24 or both | 12 or 24, borrower's choice | | Expense factor | Fixed percent, by business type, or with a tax professional letter | 40 percent fixed; lower with letter | | Minimum score | By loan purpose and tier | Varies by lender and LTV | | Max LTV | By purpose and occupancy | Varies by lender | | Reserves | Months of full payment | Varies by lender | | Account types | Personal, business or both | Both; business needs ownership proof | | NSF tolerance | Count and window | Example: limit stated per 12 months | | Overlays | Anything stricter than the guideline | Example: source for deposits over a set share | | Last confirmed | Date and who confirmed | Date entered by the broker | ### Keeping it current Review each row on a schedule, and whenever a lender sends a guideline update. A matrix that is six months old is a guess. Assign one person to own it, and have brokers add notes after every submission and decline. ### Using it on a file Take the borrower's numbers first: months of history, deposit average, score and down payment. Filter the matrix for lenders who accept those, then compare the qualifying income each would return. The profile needed for the first step is in [bank statement loans for self employed borrowers](/blog/bank-statement-loans-for-self-employed). TrueBankFlow reads 12 or 24 months of statements and recalculates total and qualifying averages as you include or exclude deposits, which helps when you compare lenders on the same file.
