The Quick Read: Documenting gap funding means building a paper trail that shows where every purchase dollar came from, what you owe, and who has a claim on the property, so the long-term lender can pay off every lien and verify your cash source at the refinance.
- Classify the gap money first: a secured junior note, an unsecured or other-property loan, partner capital, or a gift. Each needs different paper.
- Save the settlement statement, wire receipts, bank statements, and the signed gap agreement the day the purchase closes.
- Any lien recorded against the property gets paid off from the new loan, with a payoff statement and a release.
- The DSCR refinance caps cash-out at 75% LTV on standard rentals, so the stack must fit under that ceiling.
- Disclose borrowed money. Hiding it is what sinks files. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Why Gap Funding Shows Up in a BRRRR File
Gap funding is money that covers the difference between your down payment and what the first-lien rehab lender advances. Wikipedia’s entry on gap financing describes it as the space between the down payment and the amount lent by the first-lien holder, and notes the gap funder typically takes a second-position lien and often a share of the profit.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
BRRRR stands for buy, rehab, rent, refinance, repeat. The purchase side usually runs on short-term hard money or bridge financing. The exit is a long-term DSCR loan. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. It is a business-purpose investor loan, so the lender cares less about your pay stubs and more about the property and the file.
Here is where gap money bites. The exit lender has to pay off everything attached to the property. It also has to understand where your cash came from. Gap funding touches the exit in three ways: it adds to the payoff stack if it is lien-secured, it needs explaining as a source of funds, and it shrinks your cash-out headroom.
Lendmire is a broker. It arranges these exits through select lenders in a wholesale network across 41 markets, including Washington, D.C. Those lenders do the underwriting. What follows is how files tend to look from the broker’s chair.
Key Terms Defined
Gap funding: Capital that fills the shortfall between your cash down and the first lender’s advance.
Source of funds: The documented origin of the money you put into the deal.
Lien position: Where a lender stands in line to be repaid. A first lien gets paid before a second lien.
Payoff statement: A lender’s written figure for what it takes to clear a loan on a given date, including interest and fees.
Seasoning: The ownership period a lender wants before it will refinance on current value. Many programs in the network look for about 6 months, measured from title recording.
DSCR (debt service coverage ratio): Monthly rent divided by the monthly PITIA, which is principal, interest, taxes, insurance, and any association dues.
Cost basis: What you actually paid for the property plus documented improvements.
Step One: Map the Capital Stack at Purchase
Write down every dollar layer before you close: the first-lien advance, your own cash, and the gap piece. Hard money lenders generally want you to have real money in the deal. Hard money leverage on the Lendmire hard money program varies by lender, property, and experience. Fix-and-flip advances run as a share of project cost, tiered by completed projects, and every tier is capped at 75% of after-repair value. Rehab funds are released in draws against completed work.
That draw structure creates its own gap. You front rehab dollars, then get reimbursed. The money you front needs a documented source too.
Honest note on the economics: gap capital is expensive. A lender in the junior position takes more risk and prices for it. Adding a layer can eat the margin that makes the strategy work. The Motley Fool’s BRRRR explainer describes the common rule of thumb that total purchase and rehab costs should stay at or under 70% of after-repair value. A deal that needs gap money often fails that test by itself. Treat that as a warning light, not a rule that decides your file.
Step Two: Classify the Gap Money
Classification decides the paperwork. Here is how the main types compare.
| Gap money type | Secured on subject? | What goes in the file |
|---|---|---|
| Junior or subordinate note | Yes | Recorded note, payoff statement, lien release |
| Loan secured on another property | No | Loan documents, bank trail |
| Unsecured personal loan | No | Signed note, wire record |
| Partner or private capital | Depends | Note or equity agreement, ownership terms |
| Gift | No | Gift letter, transfer record |
A lien-secured junior note. This is a payoff item at the DSCR closing. The recorded note, a payoff statement, and a lien release all matter. If the gap funder is owed a profit share at refinance, it should appear plainly on the payoff statement and title work. A recorded interest the exit lender did not expect is the sort of surprise that stalls a file.
A loan secured elsewhere, or unsecured. The subject property stays clean. The file still needs the loan agreement and the bank trail showing the funds arriving and leaving.
Partner capital. Put it in writing as a note or an equity agreement. If the partner shares profit or holds an ownership stake, the lender will want to see who owns the property and who is the borrower. Confirm early whether the lender allows the vesting you plan to use. LLC borrowers are accepted subject to lender program eligibility, and entity rules vary across lenders in the network.
Gifts. A gift letter is usually part of the package, along with proof the money moved. Lendmire’s piece How to Season and Document Down Payment Funds for a DSCR Purchase covers that paper trail in depth.
Step Three: Check the First Lender’s Rules Before You Sign
Whether gap funding is possible at all often comes down to the first-position lender. Many hard money lenders restrict additional liens on the property, and some want borrower cash in the deal. Ask in writing whether a junior lien is permitted and what the loan documents say about other debt. Do this before you sign the gap agreement, not after.
Step Four: Build the Paper Trail by Stage
Save documents when events happen, not when the refinance lender asks. Reconstructing a wire from eight months ago is miserable.
| Stage | Documents to save |
|---|---|
| Purchase | Settlement statement, wire receipts, bank statements |
| Gap funding | Signed agreement, note, any recorded lien |
| Rehab | First-lien note, draw history, invoices, receipts |
| Lease-up | Signed lease, proof of deposit and first rent |
| Refinance | Payoff statements, lien releases, entity documents |
The lease items support the rent side of the DSCR calculation, not the gap money itself. Still, a missing signed lease or deposit proof is a common stall point on exit files, so gather them alongside the rest.
The Temptation to Disguise Borrowed Money
Investors sometimes ask whether they can park borrowed funds in an account for a few statements so the money looks like savings. Don’t. An underwriter reviewing statements sees large deposits and asks about them. A loan agreement, a wire record, and a repayment plan answer that question cleanly. Concealment turns an ordinary documentation item into a credibility problem.
Worked Example: The Payoff Waterfall
These are modeled assumptions, not market data. Say you buy a duplex through hard money, and a private lender provides a junior note secured on the property for part of your down payment. You rehab it, lease both units, and apply for a DSCR cash-out refinance.
The new DSCR loan needs to pay off, in order: the first-lien hard money balance, the junior note with accrued interest and any profit share, and closing costs. Cash-out on a standard rental through the network tops out around 75% LTV, so the total payoff must fit under 75% of the appraised value for you to receive anything back. If the appraisal lands short, you bring cash to the table instead of taking cash out. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Now the coverage test. Say the rent supports a coverage ratio of roughly 1.2x on the new payment. That clears the 1.00 floor where many select programs start, and a separate select-lender path exists below 1.00 with leverage and terms adjusted. Notice what the ratio ignores: the old hard money and gap payments are irrelevant once they are paid off. The new loan’s payment is what gets tested.
Clearing 1.00 also does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside it.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
What the Exit Lender Does With All This
Across the network, exit files get reviewed on several gates at once: appraised value against the leverage cap, rent against PITIA, credit, reserves, and seasoning. Credit floors begin around 620 in parts of the network, most programs want about 660, and 700 or higher unlocks stronger tiers. Reserves commonly run around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. Standard programs run up to $3,000,000.
Gap money matters at the first gate and the last. It lowers your equity if the debt stays on the property, and it complicates the source-of-funds story if documentation is thin. A large appraisal does not fix a messy file, because leverage caps, coverage, and seasoning are separate hurdles. Some investors plan the exit through Lendmire’s hard money exit refinance program, where the long-term DSCR loan pays off the bridge once the property is stabilized.
One practitioner pattern worth knowing: files that arrive with a single organized folder, including payoff letters ordered before the application, tend to move through review with fewer follow-up requests. Files that make the underwriter hunt for a junior lien’s release do the opposite.
A Quick Contrast With Agency Rules
Conventional agency guidelines have a delayed financing exception for cash purchases. Fannie Mae’s Selling Guide requires, among other conditions, that the original purchase be an arm’s-length transaction. That rule does not govern DSCR loans, and it fits a cash purchase, not a lien-secured one. Each lender in the DSCR network sets its own seasoning and documentation. The agency rule is useful only as a reminder of what every lender worries about: who paid, with what money, and whether the seller was a stranger.
How Gap Money Breaks an Exit
- Appraisal comes in short. The payoff stack no longer fits under the cash-out ceiling. Fix: size backward from the exit before you borrow the gap.
- Rent is thin. Coverage falls below 1.00. Options include a select-lender path below 1.00 with leverage and terms adjusted, or a different structure, subject to lender review.
- A lien lingers. The release is missing or the payoff figure is stale. Fix: request updated statements before submission.
- Undisclosed money. The statements show deposits nobody explained. Fix: document everything up front.
- Seasoning is incomplete. Many programs look for about 6 months from title recording. Confirm timing before you plan the refinance.
Gap funding is also not a way to avoid putting cash in. Practitioners who write junior loans describe the safest use as a borrower who has the money but wants to preserve it for rehab or reserves. A borrower with no money in the deal is the riskiest case for everyone involved.

Frequently Asked Questions
Can gap money be borrowed?
Yes, but it must be disclosed and documented. A signed loan agreement and a wire record show the lender where the money came from and what you owe. Secured versus unsecured status determines whether the payoff stack grows at the refinance.
Does gap funding have to be secured by the property?
No. It can be a junior lien, a loan secured on another property, or an unsecured note. A lien on the subject becomes a payoff item at the DSCR closing, so it needs a payoff statement and a release.
What if my partner provides the gap money?
Paper it as a note or an equity agreement. If the partner holds ownership, the lender will want to see who is on title and who is the borrower, subject to lender program eligibility.
Is a gift different from a gap loan?
Yes. A gift is not repaid, so it usually needs a gift letter and a transfer record rather than a note. A loan appears as debt and must be accounted for in the payoff or reserves picture.
Does the DSCR lender count my gap payment in the coverage ratio?
Not if the debt is paid off at the refinance. The DSCR test uses the new loan’s PITIA against rent. Debt that stays in place after closing changes the picture, so confirm how a lender treats it before applying.
