The Quick Read: Gap money is a second source of capital that fills what a hard money first lien will not fund. It only works if the long-term DSCR loan that replaces the hard money can pay off every lien on the property. Size the stack backward from that exit, and set it up before the hard money loan closes.
- Hard money lenders cap leverage by project cost and by after-repair value (ARV), so a gap usually covers the leftover slice of down payment, closing costs, or carry.
- Gap money is the costliest layer in the stack, and some funders ask for a share of profit on top of fees.
- The DSCR refinance must retire the hard money, the gap loan, and exit costs, so the payoff stack decides your break-even appraisal.
- A bigger payoff stack means a bigger new loan, which lowers your coverage ratio.
- Get the hard money lender’s written consent to a second lien first. Many refuse.
What Gap Money Is (and What It Isn’t)
Gap money covers the difference between what the first-lien lender funds and what the project costs. It can pay for part of the down payment, closing costs, the first rehab draw, or interest carry. It is not a replacement for the hard money loan, and it is not free.

BRRRR stands for buy, rehab, rent, refinance, repeat. The standard path, as AirDNA’s BRRRR explainer describes it, is a short-term loan to buy and renovate, then a refinance into a long-term mortgage. Gap money sits in the middle of that path. It gets you into the deal and has to be gone by the time you come out.
Investors often say 100% financing when they stack hard money and a gap loan. There is no true 100% purchase program behind that phrase. What exists is a first lien at high loan-to-cost plus a second layer of capital, and the exit has to absorb both.
| Layer | Role | Lien position | Repaid from |
|---|---|---|---|
| Hard money loan | Buy and rehab | First | DSCR refinance |
| Gap loan | Fill the remainder | Usually second | DSCR refinance |
| Partner equity | Shared ownership | None | Profit split |
| Your own cash | Skin in the game | None | Not repaid |
Key Terms Defined
ARV (after-repair value): what the property should appraise for once the work is done.
Loan-to-cost: the loan as a percentage of purchase price plus rehab budget, rather than of value.
Seasoning: the waiting period a lender wants between buying a property and refinancing it on a higher value.
Intercreditor agreement: a contract between two lenders fixing who gets paid first and how each acts in a default.
Payoff letter: a lender’s written statement of what it takes to clear its lien on a given date, including interest and fees.
PITIA: principal, interest, taxes, insurance, and any association dues. The monthly payment a DSCR lender tests rent against.
What Does the Hard Money Lender Allow?
Start with the first lien, because it sets the gap. Across a wholesale network, hard money for a fix-and-flip or BRRRR purchase typically runs up to 93% of project cost for borrowers with five or more completed projects, 90% at two or more, and 85% below that. Every tier is capped at 75% of ARV. Rehab funds in draws, up to 100% of the rehab budget against completed work. The top tier goes to experienced investors, and all of it varies by lender, property, and experience.
So the gap is roughly what is left: total cost, minus first-lien proceeds, minus the cash you commit. Closing costs and early interest often add to it.
Now the part that trips people up. Many hard money lenders prohibit a second lien outright. Some sell their notes after closing, and a junior lien makes the note harder to sell. Others allow a second lien but want it disclosed, limited in size, and recorded after theirs.
Ask before you sign anything. If the answer is no, you have three alternatives: bring a partner who owns equity rather than holds a lien, put in more of your own cash, or renegotiate the deal.
Three Ways to Structure the Gap
A second lien behind the hard money. This is the classic version. The gap lender records behind the first lien, usually under an intercreditor agreement. It has the cleanest paper trail and the highest cost. At exit, the gap lender provides its own payoff letter, and any profit share or fee comes out of your refinance proceeds.
Seller carryback in second position. The seller finances part of the price. This can be cheaper, but the first-lien lender has to approve it. Some lenders do not want a second lien recorded the same day as their own.
Unsecured or partner capital. No lien means nothing to release at closing. The DSCR lender may still ask where your down payment came from and whether any repayment obligation exists elsewhere. Disclose it either way. A partner who takes equity also changes who owns the property, so the entity and title have to match what the exit lender will underwrite. Loans to LLC-titled borrowers are subject to lender program eligibility.
One rule holds across all three. Title searches and settlement statements show liens, and an undisclosed second lien is a problem you create for yourself. Put every layer in writing, and tell each lender about the others.
How the DSCR Lender Treats the Stack
Here is the exit step by step, from the underwriting side. A DSCR loan qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It still has value, credit, reserve, and leverage tests.
1. Value sets the ceiling. The new lender orders its own appraisal. Your ARV is a plan, not a number the lender has to accept.
2. The new loan must pay off everything. The hard money principal, accrued interest, extension fees, and any exit fee all get paid. So does the gap lender’s payoff, plus any profit share. Closing costs come on top.
3. Leverage is tested on the new loan. This is a DSCR refinance, so the leverage limits come from the DSCR lender’s program, not from the hard-money loan’s cost-based structure. Those limits depend on whether the refinance is cash-out or rate-and-term, and a rate-and-term refinance with no cash back at closing generally allows more leverage than a cash-out refinance. Both depend on the lender, credit, and property.
4. Rent is tested against the new payment. Coverage is monthly rent divided by PITIA on the new loan. Many select programs start at 1.00. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger coverage opens better pricing and leverage.
5. Credit and reserves apply. A 620 floor exists in parts of the network, most programs want around 660, and 700+ opens the strongest tiers. Reserves commonly run about 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. They vary by lender, leverage, and transaction type.
6. Seasoning applies to cash-out. About 6 months of ownership, measured from title recording, is the common expectation for a cash-out refinance.
7. Any surviving junior lien has to be subordinated or paid. Subordination needs the junior holder’s written consent, and the holder can refuse. In practice, most files pay the gap lender off at closing.
Two clarifications keep expectations honest. Clearing 1.00 does not mean the property produces positive cash flow, since repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. And a bigger down payment on a purchase helps coverage, but it never erases leverage caps, credit floors, or reserve rules. The strongest files clear two tests: enough equity and enough rental coverage.
For more on the hard money side of that handoff, Lendmire’s page on the hard money exit refinance covers how the path works. The complete DSCR loans guide covers the underwriting basics.
Sizing Backward From the Exit
Run this before you make an offer. It takes five lines.
1. Add the hard money principal, the gap principal, and the expected interest through the exit date.
2. Add extension fees, exit fees, and any gap profit share.
3. Add refinance closing costs.
4. Divide that total by the LTV ceiling for your exit loan (75% for a cash-out on an investment property).
5. The result is the appraisal you need just to break even.
If your plan has a 70%-of-ARV cost basis, the stack alone nearly fills the ceiling once gap debt and carry are added. The Motley Fool cites keeping total purchase and rehab costs at or under roughly 70% of ARV as a rule of thumb, so the refinance has room.
Here is a modeled example in index points, where ARV equals 100. These are assumptions for illustration, not market data. All-in cost is 70. The hard money loan funds 90% of that cost. In the gap case, a second lien covers the remaining portion of the cost. Interest, fees, and exit costs add to the stack, bringing it to 74. In the no-gap case, you cover the remaining portion yourself, and carry on the smaller loan is lower, so the stack is 66.
| Appraised value | Max loan at 75% | With gap (stack 74) | No gap (stack 66) |
|---|---|---|---|
| 100 | 75.0 | +1.0 cash back | +9.0 cash back |
| 95 | 71.25 | -2.75 short | +5.25 cash back |
| 90 | 67.5 | -6.5 short | +1.5 cash back |
The break-even appraisal is about 98.7 with gap and 88 without. The gap case leaves you almost no room for a miss. That is what a stacked deal looks like when it works on paper.
Coverage moves too. The larger payoff stack, 74 versus 66, means a principal-and-interest payment roughly 12% bigger. Taxes and insurance stay fixed, so coverage slips a bit less than that. A file that sat near 1.20x on the smaller loan can drift toward the 1.10s on the larger one. Not a disaster, but it matters if the rent is thin.

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.
Where the General Rule Breaks
The hard money lender forbids a second lien. Then gap debt is off the table. Partner equity, more cash, or a smaller deal are the real options.
Same-day recording. First-lien holders often want their lien recorded first, and some will not allow a second lien to record at the same closing. Sequence it with your title company before the hard money closes, not after.
The gap note matures before seasoning ends. This is the quiet killer. If the gap loan comes due before you can cash out, you are stuck. The usual fixes are a payoff-only refinance now followed by a cash-out later, an extension while the loans are performing, or paying the gap down from other funds. Hard money terms run 6 to 18 months, so line the maturities up on paper. Gap loan maturity should match or beat the hard money maturity.
Unsecured gap money. The exit lender won’t see a lien, so nothing needs releasing. It may still ask about borrowed funds, and it can consider the repayment obligation elsewhere. Disclose it.
Delayed financing doesn’t solve it. The agency market has a delayed financing exception for cash purchases. It is an agency rule, not a DSCR feature, and it applies to cash buyers. A purchase funded by a hard money loan generally does not fit it. Whether a DSCR lender offers a similar path is lender-specific, so ask.
Properties the network doesn’t offer. DSCR loans on manufactured homes (single- and double-wide), log homes, and barndominiums are not offered. If your BRRRR target is one of those, the exit has to come from somewhere else.
When Gap Money Is the Wrong Tool
Gap money is the wrong answer when the margin is thin. If the break-even appraisal sits near your ARV, a modest miss turns a no-money-in deal into a cash-to-close deal. Low appraisals are one of the most common stall points on a BRRRR refinance, and a stacked deal has the least room to absorb one.
Skip the gap if any of these apply:
- The break-even appraisal is within a few points of your expected value.
- Your coverage ratio on the larger payoff stack falls under what your target program wants.
- The gap note matures before the exit window opens.
- The hard money lender’s consent is not in writing.
- You cannot cover reserves and exit costs from cash that is not already committed.
Better options exist. You can reduce the purchase price, trim the rehab scope, bring in a partner, or walk. Walking costs you nothing but the time you spent.
Tax treatment varies; consult a qualified professional.
Pre-Offer Checklist
Work through this list before you make an offer, from the exit backward.
1. Pick the DSCR exit program and note its leverage ceiling, coverage floor, credit tier, and seasoning rule.
2. Estimate rent and check coverage on the full payoff stack, not just the hard money loan.
3. Calculate the break-even appraisal and compare it with a conservative ARV.
4. Confirm the hard money lender allows a second lien, in writing.
5. Match the gap maturity to the hard money maturity and the seasoning window.
6. Decide in advance how the gap lender will be paid off, and get a payoff letter in the plan.
7. Hold cash for fees, interest, and reserves. A gap loan rarely covers those.
If the honest answer to any item is no, the deal needs more room. Lendmire’s article Hard Money Loans for BRRRR Rehabbers: Plan the DSCR Exit First walks through the same discipline from the hard money side.
Frequently Asked Questions
Can gap money be used on a BRRRR, or is it only for flips?
Yes, it works on both, but BRRRR adds a second job: the stack must survive a refinance. A flip repays everything from a sale. A BRRRR repays from a new loan, so the leftover value after the stack decides whether you get cash back.
Will a DSCR lender pay off a second lien at closing?
Generally, yes. Most files simply pay the gap lender off through the settlement, using a payoff letter. If the junior lien is meant to stay, it needs written subordination from the junior holder, and it tightens both coverage and combined leverage. Lender guidelines decide.
Can I skip gap money altogether?
Yes, and often you should. Bringing your own cash lowers the payoff stack, widens your appraisal cushion, and avoids a second lender’s fees and consent. The tradeoff is less leverage on the front end and fewer deals at once.
What if the appraisal comes in low?
You have fallback options. Take a payoff-only refinance now and a cash-out later, shrink the loan, add cash at closing, or extend the bridge if the lender allows it. A stacked deal has fewer of these, because the gap loan keeps your payoff high.
How much cash do I still need with a gap loan?
More than people expect. Lender fees, third-party closing costs, interest carry, and exit reserves usually stay with you. Reserves on the DSCR loan commonly run around 6 months of PITIA, varying by lender, leverage, and loan size.
