The Quick Read: A refinance is a brand-new underwriting decision. The new lender re-reads your deposits and ignores the income figure behind your old loan. Shifted deposits change your qualifying income, but they rarely end the conversation, because the statement window, the account type, and the program choice give you real levers.
- Your old approval does not carry over. Deposits are totaled, cleaned, and averaged again from scratch.
- A 12-month window locks in recent weakness. A 24-month window blends in stronger months but still shows the trend.
- Transfers, loan proceeds, and refunds come out of the total. Large one-time deposits usually need a written explanation.
- Owner-occupied cash-out on this kind of program tops out at 80% LTV. Investment-property cash-out tops out around 75% LTV.
- If the property is a rental, a DSCR loan tests the property’s income instead of your deposits. It is not always the better path.
Why a Refinance Starts From Scratch
A refinance does not inherit anything from the loan it replaces. The new lender builds its own income number from its own reading of your statements. That is true even if you used the same documentation method the first time.

Many borrowers assume the first approval is a kind of credential. It is not. The old loan proved that one lender, at one moment, accepted one version of your deposits. The new lender only cares what the statements show now.
The lookback is the same on a refinance as on a purchase. The standard documentation window in the wholesale network Lendmire places files with is 12 months of statements, business or personal. Many programs also offer a 24-month option.
Here is the practical consequence. If your deposits dipped, climbed, or moved since the original loan, your qualifying income can land well above or below the old figure. Neither direction is automatic. The next sections show how the number gets built, so you can predict which way yours will move.
Key Terms Defined
Bank statement loan: a mortgage that is reviewed on documented income under the applicable program, subject to lender guidelines, using your deposit history instead of tax-return income.
Expense factor: the percentage of business deposits the lender treats as operating costs, so only the remainder counts as your income.
Lookback window: the number of months of statements the lender averages, most often 12 or 24.
Seasoning: the waiting period a lender wants between two events, such as buying a property and refinancing it.
Rate-and-term refinance: a refinance that changes your loan structure without pulling out extra cash.
Cash-out refinance: a refinance for more than you owe, with the difference paid to you.
LTV (loan-to-value): the loan balance divided by the property’s appraised value.
DSCR (debt service coverage ratio): monthly rent divided by the monthly debt payment on a rental, used to test whether the property covers itself.
Prepayment penalty: a fee some loans charge if you pay them off early.
How Underwriters Turn Deposits Into Income
Underwriters follow a consistent sequence. They total the eligible deposits, strip out anything that is not income, apply an expense factor to business accounts, and divide by the number of months. Docsumo’s income-verification explainer walks through the same sequence, including the removal of transfers from your own savings and loan proceeds.
The result is your qualifying income. It then feeds the debt-to-income calculation, much as a W-2 figure would on a conventional file.
Three things drive that number more than anything else: the account type, the expense factor, and your ownership share.
- Account type. Personal-account deposits typically count at or near full value. Business deposits are discounted by the expense factor.
- Expense factor. Programs differ. Some use a fixed factor, and some accept a ratio prepared by an accountant. A lower factor raises your income on the same deposits.
- Ownership share. If you own 60% of a business, the lender credits you with 60% of the result. The same Docsumo explainer shows that effect.
Because of the account-type rule, moving money between business and personal accounts can change qualifying income even when total revenue is flat. Across the programs Lendmire sees, this is one of the most common surprises on a refinance file.
Here is how deposits typically sort.
| Deposit type | Typical treatment |
|---|---|
| Customer payments, regular revenue | Counts (after any expense factor) |
| Transfers between your own accounts | Excluded |
| Loan proceeds, refunds, reimbursements | Excluded |
| Large one-time or irregular deposits | Needs a written explanation |
| Cash deposits with no paper trail | Often excluded |
What Changes When Deposits Shift
Deposits can shift in four ways, and each one reads differently to an underwriter.
Deposits dropped. The average falls, and so does qualifying income. Underwriters also run trend checks no matter which window you submit. A recent decline can bring a request for a written explanation, a more conservative average, added documentation, or ineligibility under that program. Which one you get depends on the size of the drop, its cause, and the lender’s overlays. An overlay is a lender’s own rule on top of the base program.
Deposits rose. Higher recent deposits do not automatically mean higher income. A short burst of strong months may be averaged down by a longer window. Lenders also tend to be cautious about a jump with no clear source.
Deposits turned lumpy. A few large deposits among many small ones draw scrutiny. Expect questions about each big item. Seasonal businesses are often better served by a 24-month window, because it captures a full cycle.
Deposits moved accounts. Programs generally rely on eligible deposits from the accounts you submit. How a lender treats a mid-window account change is lender-dependent. Mixing business and personal activity in one account is a common reason deposits get excluded.
Think through a scenario. Say you run a consulting practice, and the last four months were slower than the eight before them. A 12-month window averages all twelve and lands below your earlier figure. A 24-month window adds a stronger prior year and may land higher. The decline is still visible in the statements, and the underwriter will see it either way.
Now flip it. Picture an owner whose business account was opened midway through the window, with earlier income flowing through a personal account. The income may still be countable, but the lender will want the account history and a clean explanation. That is a documentation task, not a dealbreaker.
Why deposits fell also matters. A seasonal swing reads very differently from a lost client or a shrinking business. Lendmire’s piece Can You Qualify When Deposits Declined on a Bank Statement Loan? covers that qualification question in more depth.
Choosing Between 12 and 24 Months
The right window is the one that fairly shows your income. Pick it with the trend in mind, and do not expect it to hide anything.
| Situation | 12-month window | 24-month window |
|---|---|---|
| Recent deposits stronger | Often helps | May dilute gains |
| Recent deposits weaker | Locks in the dip | Blends in earlier strength |
| Seasonal business | Can mislead | Captures a full cycle |
| New or changing business | Cleaner history | May expose gaps |
One myth deserves a direct answer. Choosing 12 months does not hide a decline. Trend checks run under either window, so a drop surfaces regardless.
The better question is which window gives the underwriter the most accurate picture. If your best cash-flow period sits inside the shorter window, 12 months may help. If your income is uneven, 24 months usually reads as more credible.
Refinance Now, Wait, or Switch Paths?
Your choice comes down to which documentation test your file passes best. Run through the options before you apply.
| Your situation | Likely best move |
|---|---|
| Deposits steady, goal is better terms | Refinance on bank statements |
| Deposits recently dipped | Consider waiting or a 24-month window |
| Rental property, deposits weak | Look at a DSCR loan |
| Traditional personal-income documentation now shows strong income | Consider a conventional exit |
| Liquid assets large, income lumpy | Ask about asset depletion |
Staying on bank statements. This works when the trend supports your income and the new terms beat the old ones. It is the usual route for a primary residence or second home.
Waiting. If the last few months were weak and the cause is temporary, a few cleaner months can change the average. Waiting makes sense when the refinance is optional.
Moving to a DSCR loan. On a rental, a DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Your personal deposits are not the test. DSCR is not available on your primary residence, and it is not automatically better. Many investors use bank statements for the home and DSCR for rentals. Lendmire’s complete DSCR loans guide explains how that test works.
Going conventional. If your traditional personal-income documentation now shows enough income, a conventional lender at a big bank may work. Agency self-employed underwriting starts from tax-return net profit rather than deposits, so the two methods can reach very different numbers for the same person.
Asset depletion. This path qualifies from liquid assets rather than deposits. It runs up to about 80% LTV on a primary residence, subject to lender guidelines.
A Break-Even Check Without Market Numbers
You do not need current pricing to test whether a refinance makes sense. Ask four questions.
1. How long will you keep the new loan? Closing costs need time to pay for themselves.
2. What does the old loan charge to pay off early? A prepayment penalty, if there is one, belongs in your cost.
3. What is the refinance buying you? Lower monthly cost, a different term, cash for another property, or debt consolidation each have different value.
4. Does the new income number actually support the loan size?
If the savings do not clearly outlast the costs, wait. The calculator on Lendmire’s site gives an illustrative estimate once you have your own figures.
Rate-and-Term or Cash-Out: What Leverage Looks Like
Leverage depends on occupancy and on the type of refinance. Do not mix the ceilings.
- Primary residence, purchase or rate-and-term: up to 90% LTV through select lenders. The strongest files earn the top of that range.
- Owner-occupied cash-out (primary or second home): up to 80% LTV with a fixed expense ratio, and 75% when the file uses an accountant-prepared ratio. The ceiling varies by loan size and credit.
- Investment-property cash-out: tops out around 75% LTV.
- Investment purchase on bank statements: leverage varies by lender, so treat it as a case-by-case question.
Loan sizes generally run from $125,000 to $3,500,000. Reserves are commonly around six months of the housing payment. All of this is typical, not guaranteed, and every file is underwritten individually.
Occupancy also decides the paperwork. An owner-occupied refinance is a consumer mortgage, so the standard consumer disclosure rules, known as TRID, apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is a business-purpose loan and exempt from TRID. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
The Step-by-Step Process
1. Define the goal. Decide whether you want a lower payment, a different term, or cash out. The goal sets the leverage ceiling.
2. Pull your own deposit picture. Total your eligible deposits by month and note any exclusions. This is the same math the underwriter will do.
3. Choose the window. Match 12 or 24 months to the trend, as described above.
4. Check credit and equity. Credit affects pricing and eligibility, and equity decides how much you can refinance.
5. Compare programs. Look at the expense-factor method, reserves, fees, and statement window. A few lenders in the network will accept an accountant-prepared ratio, which can move income meaningfully.
6. Submit the application. Provide full statements, all pages, with explanations for anything unusual.
7. Respond to underwriting requests. Expect follow-up questions on large deposits or trends. Answer fully and in writing.
8. Review the final terms. Confirm the numbers match your goal before you sign.
Lendmire’s role is to arrange the file through lenders in its wholesale network. The lenders review eligibility and make the decisions.
Pre-Application Checklist
Clean statements make cleaner files. Work on these in the months before you apply.
- Keep business and personal activity in separate accounts.
- Avoid moving money between accounts without a record of why.
- Document any large one-time deposits with an invoice, contract, or letter.
- Gather every page of every statement, including blank pages.
- Ask your accountant whether a prepared expense ratio would help your file.
- Check your equity position and confirm any prepayment terms on the existing loan.
- Confirm seasoning requirements if you recently bought or refinanced the property.
- Hold off on big new debts or credit applications.
Many investors skip the prepayment review. It matters more than people expect, because it can change whether waiting a few months saves money.
Where the Rules Bend
A few edge cases deserve a straight answer.
High expense ratios. If your statements show expenses above about half of deposits, a lender may switch methods or point the file toward a different program. Treat that as a signal to ask about alternatives, not as a rejection.
Rental versus home. DSCR is off the table if the property is your home. For a rental, it tests the property instead of your deposits, which helps if your personal income dipped.
Other documentation paths. Profit-and-loss-only, 1099, asset-based, and full-documentation programs exist. Availability varies by lender.
Seasoning on cash-out. Some lenders want a waiting period before they refinance a recently purchased property at a new appraised value.
Prepayment penalties. Many DSCR loans carry one, and the length and cost vary by program. Read the terms before committing.
Earlier-loan quirks. An unusual structure on your current loan, such as an interest-only period, can affect your payoff plan. Extended terms follow each lender’s program sheet, so do not assume a particular term length.
What a Decline Actually Tells You
If a lender declines an owner-occupied refinance, the reason matters. Lenders making consumer mortgages must show a reasonable, good-faith determination that you can repay, under the federal ability-to-repay rule. Bank statement programs are one way to document income under that rule. Non-QM does not mean no documentation. It means a different documentation path.
A decline also triggers a notice. Federal lending rules call for a statement of reasons, and a written request for those reasons must be honored if you make it within the timeframe the rule sets, according to 12 CFR Part 1002.
The reason tells you what to do next. A decline tied to a lender overlay may be fixable with a different lender. A decline tied to the deposit trend means the fix is time, documentation, or a different path. No lender can promise approval either way.

Frequently Asked Questions
Can I refinance a bank statement loan with the same documentation method?
Yes. Most programs let you refinance on bank statements again, as either rate-and-term or cash-out. The new lender builds its own income number from fresh statements. Your old loan’s income does not transfer.
Can I switch lenders when I refinance?
Yes. You are not tied to the lender on your current loan. Overlays and capacity differ across lenders, so a different lender may read the same file more favorably. Nobody can promise that outcome.
Do large deposits count toward my income?
Often not without an explanation. Transfers, loan proceeds, and refunds are excluded. Large or unusual deposits usually need a letter and supporting records. Documented business revenue can count, subject to lender guidelines.
What if my income dropped since the original loan?
Your qualifying income will probably be lower, and the lender will see the trend under either window. You may be asked for an explanation or added documentation. If the property is a rental, a DSCR loan may avoid the issue because it tests the property’s income.
Is there a prepayment issue on my existing loan?
It depends on the loan terms. Many DSCR loans carry a prepayment penalty, and some other loans do too. Check your note before applying, and include any penalty when you test break-even.
