The Quick Read: A bank statement loan is reviewed for a self-employed buyer on documented deposits instead of traditional personal-income documentation, and a waterfront estate adds a second file on top of the income file: appraisal, flood and wind coverage, and shoreline structures. Both files have to hold. Through select wholesale programs, subject to full underwriting, qualifying income is eligible deposits over 12 or 24 months, reduced by an expense ratio, then tested against the full carrying cost of the home.
- Income comes from 12 or 24 consecutive months of personal or business statements.
- A fixed expense ratio of 20%, 40% or 50% applies to business accounts, or an accountant-provided ratio.
- Debt-to-income can run to 50%, and insurance on a coastal estate counts in that test.
- Leverage steps down as the loan grows. Above $4,000,000 every file is reviewed case by case before submission.
- A rental-only waterfront estate may fit a property-income program better than a deposit-based one.
How Does the Loan Work, Step by Step?
The loan turns deposits into a monthly income figure, then compares that figure to every housing obligation. Nothing is skipped. It is a different way of documenting income, not an absence of documentation. Here is the sequence on a typical file through select wholesale programs.
1. Choose the statement set. The borrower supplies 12 or 24 consecutive months of personal or business statements. Business statements need at least 25% ownership. Statements must be consecutive, and a transaction history never substitutes for them.
2. Screen the deposits. Underwriters pull out credits that are not income: transfers between the borrower’s own accounts, loan proceeds, refunds, one-time windfalls. Transfers from the borrower’s own business into a personal account count in full.
3. Apply the expense ratio. On business statements the lender sets it. The fixed options are 20% for a service business with no employees, 40% for one to five employees, and 50% for six or more employees or any product business. An accountant-provided ratio is another route. A profit-and-loss method exists too, capped at 80%.
4. Average over the window. Qualifying income is eligible deposits divided by the months reviewed, after the expense ratio.
5. Test the whole obligation. Debt-to-income can run to 50%. The housing payment includes taxes, insurance and any association dues, and other mortgages count against you.
6. Review the property. Appraisal, flood determination and insurance quotes run alongside the income review.
7. Check credit and reserves. The floor is 660 on the portfolio non-QM program, 680 on the bank portfolio program, and 700 above the super-jumbo line on the portfolio program. Reserves run 3 months to $500,000, 6 months to $1,500,000 and 9 months above, plus 2 months per additional financed property to a 12-month maximum.
The federal consumer-finance regulator’s small-entity compliance guide explains that deposits count as a consumer’s income only if the creditor actually relies on them. That is why screening matters.
Key Terms Defined
Expense ratio. The share of business deposits treated as operating cost, removed before income is counted.
Eligible deposits. Credits the underwriter accepts as real income after screening out transfers, loan proceeds and windfalls.
Debt-to-income (DTI). Monthly obligations divided by qualifying monthly income. Through select programs it can run to 50%.
Super jumbo. A loan large enough to trigger extra overlays, starting above $3,500,000 on a primary residence and $3,000,000 on a second home or investment property.
Special Flood Hazard Area. A mapped zone where flood insurance is mandatory on federally backed mortgages.
A Worked Example: Deposits to Qualifying Income
Run the logic with round, illustrative inputs. Say a founder with a product business shows steady deposits across 12 months. The 50% ratio applies, so half of the monthly average is treated as cost. The remaining half is the qualifying income. A service business with no employees keeps 80% of its average deposits, because its fixed ratio is 20%.
Same deposits, very different income. That gap is why borrowers with a CPA often ask for an accountant-provided ratio instead of a fixed one. Then the waterfront adds its own weight. Tax, wind and flood premiums, and any association dues, sit in the payment. Qualifying income that clears a modest house can fall short once coastal insurance is counted.
Picture a buyer whose deposits support a comfortable DTI on an inland property. Move the same buyer to a bayfront home at the same price and the insurance line alone can push the ratio toward the 50% ceiling. The income did not change. The payment did.
Who This Fits, and Who It Doesn’t
| Profile | Fit | Why |
|---|---|---|
| Founder with strong, steady deposits | Good | Deposits show cash flow traditional personal-income documentation hides |
| Physician or attorney with a practice | Good | Business statements, accountant ratio |
| Lumpy or falling deposits | Weak | Average drops after screening |
| Commingled personal and business funds | Weak | Hard to separate eligible deposits |
| Asset-heavy, low-deposit borrower | Other path | Asset-based options may fit |
| Rental-only waterfront estate | Other path | Property income may be the stronger test |
What a Waterfront Estate Adds to the File
The property file runs on its own track. Strong income does not fix a weak appraisal.
Appraisal and comparable sales
Waterfront estates are thin on comparables. A high price does not establish value, and limited comps can lead to extra review or a second valuation. When the appraisal lands under the contract price, leverage is figured on the lower value, so the buyer brings more cash. Features such as acreage, accessory buildings and private roads can add review. Ten acres is the maximum above the super-jumbo line, and rural property is excluded there.
Flood and wind coverage
Flood insurance is mandatory for federally backed mortgages on buildings in Special Flood Hazard Areas, per FEMA’s flood insurance chapter. Whether a non-federally-backed loan carries the same requirement is the lender’s call, and most lenders require coverage regardless. The National Flood Insurance Program caps building coverage well below the value of a high-end home. On a multi-million-dollar estate that leaves a gap, so excess or private coverage is common. Every premium dollar goes into the payment. Get binders and the flood determination in early. A stale quote that changes mid-review is how a clean file turns into a DTI problem.
Seawalls, docks and bulkheads
Shoreline structures often draw separate inspections. A marine contractor’s look at the seawall, pilings and dock gives the buyer a repair picture before the appraiser raises it. A failing bulkhead can become a condition on the file.
Condos on the water
A waterfront condo adds association reserves, shared insurance and special-assessment questions. Through select programs, warrantable condos go to 85% and non-warrantable to 80%, and condotels are lower. Association paperwork is a common source of delay in the file, so request it at the start.
How Much Leverage Does a Large Waterfront Loan Get?
Leverage steps down as the loan amount rises. The bands apply to the loan amount, not the purchase price, so multiply price by leverage first, then read the band. Every figure below is a ceiling through select wholesale programs, subject to full underwriting.
| Loan band (primary residence) | Purchase | Program |
|---|---|---|
| $300K–$1M | 90% | Portfolio non-QM |
| $1M–$1.5M | 85% | Portfolio non-QM |
| $1.5M–$2M | 85% | Portfolio non-QM |
| $2M–$3M | 80% | Portfolio non-QM |
| $3M–$3.5M | 75% | Portfolio non-QM |
| $3.5M–$4M | 75% | Portfolio non-QM, super-jumbo overlays |
| $4M–$5M | 65% | Bank portfolio, on review |
| $5M–$6M | 60% | Bank portfolio, on review |
| $6M–$10M | 60% | Bank portfolio, on review |
| $10M–$30M | 55% | Bank portfolio, on review |
The portfolio non-QM program runs to $6,000,000. The bank portfolio program carries twelve-month-statement files from $4,000,000 up to $30,000,000, overlapping the first program to $6,000,000 and standing alone above it. Everything above $4,000,000 is reviewed case by case before submission. Credit needs rise with leverage: the top cell in a band asks for more than the program floor, and a lower score takes a lower cell in the same band.
Second homes and investment property use their own ladders. Read the figures from that occupancy’s table, never by subtracting from the primary-residence numbers. Above $3,500,000 on a primary residence, and $3,000,000 on a second home or investment property, super-jumbo overlays apply: a 700 credit floor, 0x30x24 housing history, 48-month seasoning on credit events, U.S. citizens and permanent residents only, no non-occupant co-borrowers, and cash-out proceeds that cannot satisfy reserves. Second homes are one unit only.
Cash-out gets a lower ceiling than purchase. Proceeds are unlimited at or below 60% LTV, and above that the portfolio program caps cash in hand at $1,500,000. Interest-only exists, but it never raises a cash-out ceiling. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Primary, Second Home or Rental: Which Test Applies?
The occupancy decides which test the lender runs. A bank statement loan is mainly built for a primary residence or second home, with some investment use. A pure rental estate generally points toward a property-income program. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, while a bank statement loan is reviewed on the borrower’s deposits.
| Factor | Bank statement | DSCR |
|---|---|---|
| What is tested | Borrower deposits | Property rent vs. debt |
| Typical title | Personal name | Entity-friendly |
| Weak spot on a waterfront | Insurance in DTI | Low rent-to-price ratio |
| Best for | Strong deposits | Strong rental income |
A waterfront estate often rents for little relative to its price, and coastal insurance is heavy. That can leave rental coverage thin. A self-employed borrower with strong deposits may do better on the deposit path, if occupancy fits. Programs below 1.00 coverage exist through select lenders in the network, but leverage and terms adjust. Lendmire’s complete DSCR loans guide walks through that test. 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.
Large and Unusual Deposits
Estate-scale buyers often have big credits on their statements. A business sale, a transfer between accounts, a gift. Each is treated differently. Transfers between your own accounts are screened out. Gifts and business funds do not count as qualifying assets on the asset paths. A sale’s proceeds may support reserves or a down payment, but a one-time credit does not inflate monthly income. Clean up commingled accounts and label unexplained deposits before you apply.
Other Paths When Deposits Aren’t the Right Tool
Not every high-net-worth profile fits a deposit average.
- Asset allowance. Liquid assets are divided by 36, 60 or 84 months to create income. Primary and second homes only, to 80%. The 84-month divisor applies to standalone use or any loan above $3,500,000.
- Assets-only. Qualifies with no DTI when U.S. liquid assets equal the loan plus closing costs plus sixty months of any net loss on other residential property. Retirement accounts count at 70%, or 80% at age 59.5 and over. Business funds, gifts, cryptocurrency and unvested stock never count.
- Profit-and-loss method. Capped at 80% on the expense side and generally needs accountant support.
A self-prepared P&L does not meet the third-party verification standard. A statement prepared or reviewed by a third-party accountant can be used to verify income.
Bank statement loans carry an honest caveat: if you qualify for a conventional or government-backed loan, that is likely the better option. Bank statement files exist for borrowers whose returns understate their income.
Pre-Application Checklist
- Pull 12 or 24 consecutive statements for every account you plan to use. Missing pages stall the file.
- Mark every transfer, loan and one-time deposit.
- Separate personal and business money where you can.
- Ask your CPA whether an accountant-provided expense ratio applies.
- Get insurance quotes for wind and flood, plus the flood determination, before submitting.
- Gather association documents for any condo.
- Order a marine inspection for seawalls and docks if the property has them.
- Confirm reserves in eligible accounts, since cash-out proceeds cannot cover reserves on super-jumbo files.

Frequently Asked Questions
Can I use a bank statement loan if the waterfront estate is a rental?
Sometimes, through select programs that allow investment property, but the leverage ladder is its own and often lower. A rental-only estate usually tests better on property income through a DSCR program. The choice depends on which number is stronger, your deposits or the rent.
Does the expense ratio come out of my deposits or my income?
It comes out of your business deposits. The lender sets it at 20%, 40% or 50% depending on the business, or uses an accountant-provided ratio. You cannot pick a lower figure without third-party support.
Will flood insurance be required?
It is mandatory for federally backed loans in Special Flood Hazard Areas. For a non-federally-backed loan the lender decides, and most ask for coverage on coastal property. Because the National Flood Insurance Program caps building coverage well below the value of many higher-priced homes, an estate often needs excess or private coverage.
What happens if the appraisal comes in low?
Leverage is applied to the appraised value, not the contract price. The buyer then covers the gap with more cash, and reserve needs can change. Appraisal reconsideration with stronger comparables is a normal next step.
Do large deposits from a business sale count as income?
Not as recurring monthly income. One-time credits are generally screened out of the average. They may still help with down payment or reserves, subject to documentation and lender guidelines.
