The Quick Read: How much you can borrow depends on your deposits, debts, credit and the property, not on the boat. Through select wholesale programs, loan sizes run from $300,000 up to $30,000,000, subject to full underwriting. A bank statement loan is for real estate, not for the boat, and the boat is never the collateral on this kind of mortgage. It only shows up on the file as a debt, a deposit source, or an asset that rarely helps.
- Loan size is set by qualifying income from 12 or 24 months of deposits, plus debt-to-income, credit, loan-to-value and reserves.
- A financed boat adds a monthly debt to your file, which can lower what you can borrow.
- Boat-sale proceeds and money moved in from your own savings or brokerage accounts are not income, and underwriters strip them out. Transfers from your own business into your personal account are the exception and count in full.
- Boats are typically financed through separate marine loans, not mortgages.
- Rental investors can skip the income math entirely with a DSCR loan, which qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
Three Readings of the Question
The phrase “boat owners” hides three different borrowers, and the answer is different for each one. Sort yourself into one of these before you look at any numbers.
| Scenario | Bank statement loan relevant? | What secures it | What the lender tests |
|---|---|---|---|
| Buying or refinancing a home or rental | Yes | The real estate | Deposits, DTI, credit, LTV |
| Buying or refinancing the boat | Not a standard fit | The boat | Marine lender’s own rules |
| Owning a boat while borrowing on property | Yes, boat is a side factor | The real estate | Boat payment in DTI, boat deposits |
Most of this article covers the first and third rows, because that is where a bank statement loan lives. A bank statement loan is a mortgage. It is a non-QM loan, meaning it falls outside the standard rules that agency-style mortgages follow, and it exists for self-employed borrowers whose traditional personal-income documentation understates what they really earn.
If you own a charter company, a marine repair shop, a dealership or a fishing operation, write-offs shrink your taxable income. Bank statements show the cash that actually moved. That is the whole idea.
How Much Can a Boat Owner Borrow?
Through select wholesale programs, loan amounts run from $300,000 to $30,000,000, subject to full underwriting. Two programs cover that span. A portfolio non-QM bank statement program carries files up to $6,000,000. A bank portfolio jumbo program takes twelve-month-statement files up to $30,000,000 on its own size ladder.
That ladder begins above $4,000,000, overlaps the first program up to $6,000,000, and stands alone above that. Every loan above $4,000,000 is reviewed case by case before submission, so treat any figure at that size as a starting point for review, not a promise.
Size is only half the answer. Leverage steps down as the loan grows. On a primary residence, through select wholesale programs, typical ceilings look like this:
- Purchase up to about 90% LTV through $1,000,000.
- Purchase up to about 85% from $1,000,000 to $2,000,000.
- Purchase up to about 80% from $2,000,000 to $3,000,000.
- Purchase up to about 75% from $3,000,000 to $4,000,000, which takes the strongest credit tier.
- Case-by-case review from $4,000,000 to $6,000,000, then the bank program’s own ladder: 65% to $5,000,000, 60% to $10,000,000 and 55% to $30,000,000, all on review. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Loan-to-value, or LTV, is the loan amount divided by the property value. Second homes and investment properties take their own ladders, so read each figure from the ladder for that occupancy rather than adjusting the primary-residence numbers. Cash-out refinances on a primary residence top out around 80% at the smaller sizes and come down from there. Above 60% LTV, the portfolio program caps cash-in-hand at $1,500,000. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Now the boat. Your boat does not raise or lower any of those ceilings.
- Credit: a 660 floor on the portfolio program, 680 on the bank program, and 700 above the super-jumbo line, on most files.
- Debt-to-income: up to 50% on most files.
- Reserves: typically 3 months of payments up to $500,000, 6 months up to $1,500,000, and 9 months above that, with more required for extra financed properties.
- Super-jumbo overlays: above $3,500,000 on a primary residence, and above $3,000,000 on a second home or investment property, expect a 700 credit floor, a clean housing history, and several other tighter rules.
These are typical ranges across the wholesale network, not a commitment to lend. Every file is underwritten individually, and programs change.
How Your Deposits Become Income
Underwriters add up eligible deposits over 12 or 24 consecutive months, apply an expense ratio if the account is a business account, and divide by the number of months. The result is your monthly qualifying income. Scotsman Guide describes the same basic approach, with a standard expense factor applied to the deposits. Statements must be consecutive. A transaction history printout never substitutes for them.
Business statements generally require at least 25% ownership. The expense ratio backs out the cost of running the business. On many programs it is set by business type, with a lower ratio for a service business with no employees, a higher one for a business with a handful of employees, and the highest for a larger staff or any business that sells a product. A marina or boat dealer typically lands in that last bucket because it sells product. An accountant-provided ratio, or a profit-and-loss method, may be available instead.
Personal accounts work differently. Money you move from your own business into your personal account counts in full, at 100%, because the cost of running the business was already paid before the money reached you. That is different from money you shift out of your own savings or brokerage accounts, which is not business revenue and gets stripped out.
Here is an illustrative walk-through, not a quote. Say you run a charter operation with a few employees and an assumed expense ratio of 40%, a hypothetical figure chosen for this example rather than a market statistic. Roughly 60 cents of every eligible business deposit dollar survives as qualifying income, averaged across the lookback months. Strip out anything that is not true revenue first, and the number gets smaller before the ratio even applies.
That stripping step matters to boat owners in particular. Underwriters remove:
- Proceeds from selling a boat, since a one-time sale is not recurring income.
- Disbursements from a marine loan, which are borrowed money.
- Transfers from a brokerage or savings account, which move your own funds rather than earn new income.
- Large unexplained deposits with no paper trail.
Charter, rental, guide and dealer deposits do count when they are steady revenue in the business account. Seasonal income is the tricky part. A summer-heavy charter business shows lumpy months, but a 12 or 24 month average smooths that out. If your best years are behind you, the 24-month view can help because it includes the stronger year. If the last year was a record, the 12-month view may show a higher number, so ask which period fits your file.
Where the Boat Sits in the File
The boat is a liability, a minor asset, or a side note, depending on how you bought it. The most common effect is the payment.
A financed boat is a monthly debt. If you carry a marine loan, that payment sits on your credit report and counts toward your debt-to-income ratio, or DTI, which divides your monthly debts by qualifying income. Picture a borrower whose new housing payment eats 38% of qualifying income. A boat payment worth another 10% pushes DTI to 48%, close to the 50% ceiling. Pay the boat loan off before you apply, and DTI drops back to 38%. Paying down or retiring a boat loan before applying can be one of the more affordable ways to widen your borrowing room, though lenders review the whole file.
A boat is rarely a reserve. Reserves are the months of mortgage payments a lender wants you to hold in liquid funds. Equity in a boat is hard to turn into cash, so it typically does not count. The asset-based paths work the same way. An asset allowance divides liquid assets by 36, 60 or 84 months to create qualifying income, and an assets-only path wants liquidity equal to the loan plus closing costs. Retirement accounts count at 70%, or 80% at age 59½ and older. Business funds, gifts, unvested stock and cryptocurrency never count.
Large boat purchases shrink your cash. Money spent on a vessel is money that cannot become a down payment or reserves. That logic needs no formula.
A liveaboard is still personal property for lending. The IRS says a boat with sleeping, cooking and toilet facilities can qualify as a main or second home for the mortgage interest deduction, per IRS Publication 936. That is a tax definition. Lenders generally treat boats as personal property, and a boat does not become real estate on your application. Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
Bank Statement, Marine Loan, Home Equity or DSCR?
Pick the loan that matches what you are actually financing. The wrong match wastes weeks of paperwork.
| Loan type | What it finances | Collateral | Income test |
|---|---|---|---|
| Bank statement loan | Home, second home, rental | The real estate | Deposits after expense ratio |
| Marine loan | The boat | The boat | Lender’s own rules |
| Home equity | Anything, borrowed against a home you own | Your existing home | Varies by product and lender |
| DSCR loan | Rental property | The rental property | Property rent vs. payment |
A marine loan is the usual route for the boat itself. A home equity product borrows against a home you already own, and it carries its own limits and income rules. A bank statement cash-out refinance is another way for a self-employed owner to pull equity from a property, with leverage per the ladder above and on a primary residence typically up to 80% at smaller sizes. How you spend the proceeds is a separate question from what secures the loan.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, so the file tests the property’s rent rather than a deposit-based income figure.
For a boat-business owner buying a rental, that is the clean split. The DSCR path looks at whether the rent covers the payment. Your boat loan is generally weighed through credit and reserves rather than through personal income ratios, though how a lender treats it can vary by program. Programs below 1.00 coverage are available through select lenders in the network, but LTV and terms adjust. Lendmire’s complete DSCR loans guide walks through the property-level math.
In short, use bank statement income when you need your own earnings to support the loan. Use DSCR when the property carries itself.
Documents to Gather
Non-QM does not mean skipping paperwork. Lenders still document the income or assets they rely on, and bank statements are that documentation. A typical boat-owner file includes:
- 12 or 24 consecutive months of personal or business statements.
- Proof of ownership of the business, at least 25% for business statements.
- An accountant letter, if you want an expense ratio other than the fixed ones.
- Statements and payoff terms for any marine loan.
- Documentation explaining large one-time deposits, such as a boat sale.
- Assets paperwork if you use an asset path.
The boat’s survey, title and lien paperwork belong to a marine lender. A mortgage lender will mainly want to see the loan balance and payment if you owe on it.
When a Bank Statement Loan Is the Wrong Tool
It fits poorly in four situations. First, if you want money to buy the boat itself, a marine lender is the typical route. Second, if your deposits are mostly transfers and one-time sale proceeds, the qualifying income may be too thin. Third, if your traditional personal-income documentation already shows strong income, a conventional loan may price better. Fourth, if the property is a rental that rents well, DSCR often needs less documentation of your personal finances.
There is also a ceiling to respect. Above $4,000,000 every file is reviewed case by case, and credit, seasoning and citizenship overlays tighten. A big number on a pre-approval chat is not a loan.
Key Terms Defined
Bank statement loan: a mortgage that measures a self-employed borrower’s income from deposit history instead of traditional personal-income documentation.
Non-QM: a loan that does not follow standard agency-style mortgage rules, which lets lenders use alternative documentation.
Expense ratio: the percentage of business deposits removed to cover operating costs before income is calculated.
DTI: your monthly debts, including the new housing payment, divided by your qualifying monthly income.
LTV: the loan amount divided by the property’s value.
Reserves: liquid funds you keep after closing, measured in months of payments.
DSCR: the property’s monthly rent divided by its monthly debt obligation, used to qualify rental loans.
Frequently Asked Questions
Can I use a bank statement loan to buy a boat?
Not as a standard product. A bank statement loan is a mortgage secured by real estate, and boats are typically financed through marine lenders with the boat as collateral. If you own property with equity, a cash-out refinance is a separate transaction secured by that property, subject to the leverage ladder above.
Does owning a boat reduce how much I can borrow?
Owning one outright does not. Owing on one does, because the monthly payment counts in your debt-to-income ratio, which tops out around 50% on most files. Retiring the loan before you apply can restore borrowing room.
Does boat-sale money count as income?
No. A one-time boat sale is a non-recurring deposit, so underwriters strip it out. It may still help as liquid cash for a down payment or reserves, provided the funds are sourced and documented.
How are charter or marine-business deposits treated?
Steady revenue deposited into a business account counts, after an expense ratio of typically 20% to 50% depending on the business type or an accountant-provided ratio. Seasonal swings are averaged across the 12 or 24 month lookback, subject to lender guidelines.
Can a liveaboard boat count as my home on a mortgage application?
Generally no. The IRS tax definition of a home can include a boat, but lenders typically treat a vessel as personal property, so the mortgage is secured by real estate instead.
