The Quick Read: It depends on three inputs: the file’s total monthly obligations, the program’s debt-to-income cap of up to 50%, and the share of deposits that survives the expense ratio, which means a business-statement borrower typically needs monthly deposits of roughly 2.5 to 4 times those obligations. No published standard sets one dollar income figure for a $4 million loan. The number comes from your own file. Through select wholesale programs, subject to full underwriting, any loan above $4,000,000 is reviewed case by case before submission.
- Required qualifying income equals total monthly obligations divided by the debt-to-income cap.
- Required monthly deposits equal qualifying income divided by what the expense ratio leaves.
- Transfers from your business into a personal account count in full, so they need the least deposit volume.
- Reserves, credit, and leverage often bind before income does at this size.
- A $4 million loan and a $4 million home are different inputs.
What Is the Math Behind the Income Number?
The math is two divisions. First, divide your total monthly obligations by the debt-to-income cap. Second, divide that qualifying income by the share of deposits the lender counts.
Debt-to-income (DTI) compares your monthly debts to your qualifying monthly income. On this loan, the monthly obligations include the new housing payment, taxes, insurance, and any HOA dues. They also include every other debt on your credit report. Across the wholesale network Lendmire places files with, the DTI ceiling runs up to 50%.
At a 50% ceiling, you need qualifying income of twice your obligations. If the expense ratio keeps only half of your business deposits, you need deposits of four times your obligations. Put plainly, for every dollar of monthly obligations, the file needs about four dollars of monthly business deposits.
This article prints no payment dollars. The payment depends on the loan size and the terms of the program, and your own obligations are what drive the answer. The multiples below hold at any loan size, so you can run them on your own figures.
Is the $4 Million a Loan Amount or a Home Price?
Income scales with the loan amount, not the price. When people say $4 million, they often mean the purchase price, and that is a different input.
On a purchase, the loan is the price times the leverage ceiling. Through select wholesale programs, subject to full underwriting, the ceiling steps down as size rises. A primary residence in the $3,500,000 to $4,000,000 band tops out at 75% on a purchase, and only at the top credit tier of 760 or better. Rate-and-term refinances in that band run to 70%, and cash-out refinances to 65%.
So a $4 million price produces a loan well under $4 million, and the income target falls with it. A $4 million loan amount means a much larger property or a very large refinance. Taxes and insurance on the bigger property also raise the obligations side of the formula.
How Do Deposits Become Qualifying Income?
The lender totals your eligible deposits, removes what is not income, applies an expense ratio, and divides by the number of months. That is the whole conversion. The steps run in this order:
1. Pick the window. Lendmire’s programs use 12 or 24 consecutive months of personal or business statements. The bank portfolio program uses 12. Transaction histories never substitute for statements.
2. Total the deposits. Market explainers such as Docsumo’s bank statement income guide describe stripping out transfers between your own accounts, loan proceeds, and large deposits you cannot source. Underwriters on these files do the same.
3. Apply the expense ratio to business deposits. Fixed ratios in this network scale with business size and type, running lower for a service business with no employees and higher for businesses with more employees or any product business. An accountant-provided ratio can replace the fixed one.
4. Apply your ownership share. Business statements need at least 25% ownership. Counted income falls in proportion if you own less than 100%.
5. Divide by the months to get qualifying monthly income.
6. Run DTI against that figure, alongside credit, assets, and reserves.
HousingWire’s non-QM guide notes that the factor reflects business type, employee count, contractor use, and operating structure. That matches how the fixed ratios above are built. Bank statement underwriting changes how income is established. It does not change whether the loan is underwritten.
Personal Versus Business Statements
Personal statements need the least deposit volume when the money traces back to your business. Transfers from your own business into your personal account count at 100%, with no expense ratio on top. Business statements run through the ratio, so the same qualifying income takes more deposits.
This table shows monthly deposits needed per dollar of monthly obligations at a 50% DTI cap. The multiples are the writer’s own arithmetic on the program ratios, rounded.
| Statement path | Share of deposits counted | Deposits needed |
|---|---|---|
| Personal, business transfers | 100% | about 2.0x |
| Business, 20% ratio | 80% | about 2.5x |
| Business, 40% ratio | 60% | about 3.3x |
| Business, 50% ratio | 50% | about 4.0x |
Ownership scales every row. At 50% ownership of the business, the business rows double. A 40% ratio then needs about 6.7x.
Personal accounts also get a tighter proof test. The deposits must visibly come from the business. A founder who pays herself through a clean, regular transfer has the strongest file. A founder who lets business revenue land in a personal account without a clear trail invites questions.
What Moves the Number Most?
The expense ratio moves it most, followed by the DTI cap. The next table holds the structure constant and varies those two inputs. Cells show deposits needed per dollar of monthly obligations on a business-statement file.
| Expense ratio | At 50% DTI | At 43% DTI |
|---|---|---|
| 20% | about 2.5x | about 2.9x |
| 40% | about 3.3x | about 3.9x |
| 50% | about 4.0x | about 4.7x |
Programs in the network allow DTI up to 50%, and some files are held lower on other factors. A lower cap is how the multiple climbs. These rows are illustrations of the formula, not promises of what any file will receive.
Read the table the way an underwriter would. Moving from the 50% ratio to a documented 20% ratio cuts the deposit requirement by nearly 40%. A CPA letter that supports a lower ratio can matter more than a higher credit score. A different account mix can also matter more than another year of growth.
Lumpy deposits deserve a note. A seasonal business or a business that books a few very large invoices produces a monthly average that hides big swings. A 24-month window smooths seasonality. A 12-month window helps when the latest year was your strongest, and how to use this year’s higher income on a bank statement mortgage covers that choice. Deposits you cannot source are excluded either way.
Why Income Is Not the Only Gate at This Size
At $4 million, leverage, credit, and reserves often bind before income does. A file can clear the DTI test and still fail on any of them.
Leverage. Through select wholesale programs, subject to full underwriting, these are the ceilings around a $4 million loan. They apply to the $3,500,000 to $4,000,000 band, then to the next band, which is reviewed case by case before submission.
| Occupancy | Purchase | Cash-out |
|---|---|---|
| Primary residence, to $4M | 75% (760+ credit) | 65% |
| Primary residence, above $4M | 65% on review | 60% on review |
| Second home, to $4M | 65% (760+ credit) | 55% |
| Investment property, to $4M | 60% | 55% |
Second homes run below a primary residence, and investment property lower still at this size. A cash-out above 60% is capped at $1,500,000 cash in hand on the portfolio program. Cash-out proceeds cannot satisfy reserves.
Credit. The floor is 660 on the portfolio program and 680 on the bank program. Above the super-jumbo line, which is $3,500,000 on a primary residence and $3,000,000 on a second home or investment property, the floor is 700. Those files also want a 0x30x24 housing history and 48 months of seasoning after any credit event. They are limited to U.S. citizens and permanent residents.
Reserves. Reserves are the liquid funds left after closing. Files above $1,500,000 typically need 9 months. Each additional financed property adds 2 months, up to a 12-month maximum, and first-time investors need 12.
Program split. A portfolio non-QM program carries bank statement files to $6,000,000. A bank portfolio program takes twelve-month-statement files to $30,000,000 on its own ladder, starting above $4,000,000 and overlapping the first program to $6,000,000. A broker can see both. Lendmire’s role is to compare them for your deposits and property.
(Market color, briefly: HousingWire reports bank statement loans at 34% of non-QM volume, with DSCR loans at 29%.)
What If Your Deposits Fall Short?
You have several honest options, and most of them change the formula rather than the file.
- Document a lower expense ratio. An accountant-provided ratio can replace the fixed 40% or 50%.
- Choose the right window. Use 12 months if the latest year is stronger, or 24 months if it smooths a spike. Lendmire’s comparison of four statement combinations shows how the choice shifts counted income.
- Reroute income through personal statements. Regular transfers from your business count in full.
- Try a profit-and-loss method. It carries its own 80% cap.
- Lower the loan. Less leverage shrinks the payment, which shrinks the obligations side. It also moves the file into a more favorable row of the ladder.
- Pay down other debts. Every dollar of monthly debt removed lowers the deposits you need.
- Use assets. An asset allowance divides your liquid assets by 36, 60, or 84 months. It is limited to primary and second homes, with an 80% maximum. Any loan above $3,500,000 uses the 84-month version, so each dollar of needed monthly income calls for 84 dollars of liquid assets. Retirement accounts count at 70% (80% at age 59.5 or older). Assets-only qualification skips DTI when U.S. liquid assets equal the loan plus closing costs, plus sixty months of any net loss on other residential property. Business funds, gifts, and cryptocurrency never count.
Rentals are a separate lane. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so your deposits matter less. Sub-1.00 coverage is available through select lenders in the network, but leverage and terms adjust. The complete DSCR loans guide covers that path. Many investors use bank statements for a primary home and DSCR for rentals, because each bank statement loan adds its payment to your DTI and uses up room for the next purchase.
Common Misconceptions
No traditional personal-income documentation does not mean no income test. Bank statement files still run DTI, credit, assets, and reserves. The lender must still make a good-faith determination that you can repay, and the CFPB’s rule text says so for non-QM loans too.
Every deposit counts. Transfers, loan proceeds, and unsourced deposits come out.
The 50% expense ratio is a federal rule. It is a common default in the market and the top ratio on Lendmire’s network ladder. A documented ratio can replace it.
Bank statement loans ignore DTI. They do not. The CFPB sets no non-QM cap, so each program sets its own. The CFPB’s small-entity guide says lenders must consider DTI or residual income without naming a threshold, and it allows bank statements as verification.
Rent helps a bank statement file qualify. On a bank statement file, the property’s rent is secondary. Rent drives DSCR files.
Key Terms Defined
Qualifying income: the monthly income a lender counts after removing non-income deposits and applying the expense ratio and your ownership share.
Eligible deposits: the deposits left after transfers between your own accounts, loan proceeds, and unsourced large deposits are removed.
Expense ratio: the share of business deposits the lender treats as operating cost and does not count as income.
DTI (debt-to-income): your total monthly obligations divided by your qualifying monthly income.
PITIA: the monthly housing payment of principal, interest, taxes, insurance, and association dues.
LTV (loan-to-value): the loan amount divided by the property’s value or price.
Reserves: liquid funds you hold after closing, counted in months of the payment.
Frequently Asked Questions
Is a bank statement loan a way of hiding income?
No. Traditional personal-income documentation shows income after deductions, while statements show cash that actually moved. The file is still underwritten for DTI, credit, assets, and reserves. The expense ratio also removes part of your deposits, so the lender counts less than the gross total.
Can I mix personal and business accounts?
Yes, when the deposits trace cleanly. Business statements run through the expense ratio. Personal statements count transfers from your business in full. Underwriters will not count the same dollar twice, so a business-to-personal transfer cannot also sit in the business total.
Does 12 versus 24 months change the answer?
Yes, it can. A 24-month window averages out seasonality and a weak stretch. A 12-month window helps when your most recent year was your strongest. The bank portfolio program uses 12 months only.
What if my accountant can document lower expenses?
That is often the biggest lever you have. An accountant-provided ratio can replace the fixed 40% or 50%, and each step down cuts the deposits you need. The lender reviews the support, so the letter has to match your statements.
Do I need traditional personal-income documentation?
Not on a bank statement file. Qualification runs on documented income under the applicable program, subject to lender guidelines. Tax treatment varies; consult a qualified professional.
