Gap Funding in Real Estate: How It Works, What It Costs, and the Risks

Gap funding is short-term private money that covers the “gap” between what a hard money lender will lend and the total cash a deal needs, usually the down payment, closing costs, and points. It lets an investor close with little or none of their own money, but it typically costs far more than the first loan, and many hard money lenders prohibit it outright.

Wholesalers run into gap funding in two ways: as a pitch from lenders promising “no money out of pocket” flips, and as a question from buyers who want to take down your contract but are short on cash. This guide walks through how the structure works, current terms, a full deal example, and the specific points where it goes wrong.

Where the gap comes from

Hard money lenders rarely fund 100% of a flip. They lend a percentage of the purchase price (loan-to-cost, or LTC), often 100% of the rehab budget through draws, and cap the whole loan at a percentage of the after-repair value (ARV). Whatever is left over, the investor has to bring.

Published terms from lenders checked in October 2026 show the range:

The best terms go to experienced borrowers with strong credit. RCN’s published tiers, for example, give a first-time flipper 80% of purchase while an investor with 10 or more flips can get up to 95%. A beginner typically faces the biggest gap.

On top of the down payment, the borrower pays origination points, lender fees, title and closing costs, and sometimes prepaid interest. Experian puts typical hard money down payments at 20% to 30%. That cash requirement is the gap.

Three ways gap funding gets structured

1. A second-position loan

The gap lender records a second mortgage or deed of trust behind the hard money lender. FCTD describes standalone gap seconds at 12% to 15% interest with 2 to 3 points and roughly six-month terms. This is the cleanest structure on paper, and the one most often blocked by the first lender.

2. A profit-share or equity partner

Instead of a fixed rate, the gap funder takes a share of the profit when the property sells, sometimes with a minimum return. This looks cheaper upfront and can be far more expensive on a strong deal. It is effectively a joint venture, and it should be papered like one, with a written agreement covering who controls decisions, what happens if the project runs over, and how losses are shared. Our joint venture guide covers the agreement basics.

3. Lender-arranged gap

Some lenders offer gap money only behind their own first loan, so both pieces come from one source. Levine Capital, for example, advertises gap funding behind its own fix-and-flip loans with funder returns of 15% to 25% or more, origination from 2%, a 2% to 5% connector fee on the gap amount, a minimum 680 FICO, and combined loans capped around 70% to 75% of ARV. Because the first lender is in on it, the second-lien conflict goes away, but the stack of fees is real.

The first lender is usually the obstacle

Hard money lenders want the borrower to have their own money at risk. Many sell their loans to investors on the secondary market, and those buyers expect a clean first lien with no junior debt behind it. One lender’s underwriting guide states it bluntly: “All other secondary or subordinate debt financing is not permitted including gap funding/financing from third party investors” (MCM Capital underwriting guide). FCTD likewise notes that institutional lender notes commonly prohibit junior liens and that first lenders look for 10% to 20% of the borrower’s own skin in the game.

The practical rules:

• Disclose the gap to the first lender in writing. Hiding a second lien or a gap investor from the first lender can put you in default and, depending on what you represented on the application, create far more serious problems.
• Read the loan documents for “no secondary financing” language before you sign a gap agreement.
• If the first lender says no, the answer is no. Look for a lender that allows a disclosed second or offers its own gap product.

A full worked example

Hypothetical figures for illustration only. A newer investor buys a wholesale deal at $180,000. The rehab budget is $45,000 and the ARV is $300,000. The hard money lender funds 80% of purchase and 100% of rehab at 11% interest and 2 points, capped at 70% of ARV.

A gap lender provides $44,000 at 15% annual interest plus 3 points. Combined debt is now $233,000, or about 78% of ARV, which is above the 70% to 75% combined cap many lenders use. That alone shows why gap funding on top of a beginner-tier loan is hard to place.

If the flip goes to plan, with a sale at $300,000 in six months:

• Hard money interest, six months on $189,000 at 11%: about $10,395 (less if rehab funds are drawn gradually)
• Gap cost: six months of interest ($3,300) plus 3 points ($1,320) = $4,620
• Selling costs at roughly 8% of the sale price: $24,000
• Taxes, insurance, and utilities: about $3,000
• Estimated profit: about $25,200 on very little of the investor’s own cash

Now change two assumptions. The rehab runs long, the house sells in nine months, and the price comes in at $285,000. Hard money interest rises to about $15,600, gap cost to about $6,270, holding costs to about $4,500, and selling costs land near $22,800. The estimated profit drops to roughly $3,000. Any further slip, such as a foundation surprise or a second price cut, and the investor owes money at closing.

That is the core truth of gap funding: it magnifies outcomes in both directions. Run your own numbers with the fix and flip calculator, and test a slower, lower sale before you commit.

Market data supports the caution. ATTOM’s Q2 2026 flipping report put the typical gross profit at $60,526 and the profit margin at 21.5%, down from 27.6% a year earlier, with a median 161 days from purchase to resale. Note that ATTOM’s gross profit figure does not subtract financing, rehab, or selling costs. When a typical flip takes more than five months and margins are shrinking, expensive layered financing has less room to work.

Why this matters to wholesalers

Most wholesalers never borrow gap money themselves, because an assignment or a double close with transactional funding does not need a rehab loan. Gap funding still shapes your business in three ways:

1. It explains why some buyers fall through. A buyer counting on gap money can lose it when their first lender rejects the second lien days before closing. Ask every new buyer how they are funding the purchase, and favor buyers with their own cash or a confirmed lender.
2. It affects what buyers can pay you. A buyer paying 15% plus points on part of their capital needs a bigger spread. Price your deals with real financing costs in mind, starting from an accurate ARV and repair estimate and checking the result against the MAO calculator.
3. It is a common next step when wholesalers start flipping. If you are weighing that move, read wholesaling vs. fix and flip first. Your first flip is the worst time to have the most expensive capital stack.

Legal points to get right

Securities law. Borrowing from one private lender on one property, secured by a recorded mortgage, is generally treated differently from raising money from several passive investors. Under the Supreme Court’s Reves “family resemblance” test, a note secured by a mortgage on a home is among the categories usually not treated as a security, as this law firm analysis explains. Pooling money from multiple investors is another matter, and that is where federal exemptions such as Rule 506(b) come in, with limits on investors, a ban on general solicitation, and a Form D filing within 15 days of the first sale. If you plan to raise from more than one person or advertise for investors, have a securities attorney structure it before you take a dollar. If you are borrowing from one person on one property instead, start with how to find and work with a private lender.

Usury. Interest rate caps are set state by state, and many states treat business-purpose or larger loans differently from consumer loans. The American Bar Association notes, for example, that Missouri has no rate limits on loans to corporations, partnerships, or LLCs, while Georgia’s 16% cap applies only to loans of $3,000 or less. If you are lending, or borrowing in your own name instead of an entity, check your state’s rules.

Documentation. Every gap arrangement needs a promissory note, a recorded security instrument if it is secured, title insurance for the lender, and a closing handled by a title company or attorney. A handshake gap loan is how friends and family stop speaking to each other.

When gap funding is the wrong tool

• Your projected profit is under about 15% of ARV. The financing costs and any overrun can erase it.
• This is your first flip. Your rehab estimate and timeline are least reliable now. Wholesale or partner on the first one instead.
• The first lender has not approved it in writing. No exceptions.
• You are using it to cover a deal that does not pencil. If you need gap money because the purchase price is too high, the problem is the price.

Used carefully, by an investor with a proven rehab track record and a first lender who has signed off, gap funding can let you take down more deals than your cash allows. Used as a way to skip having any capital at all, it mostly transfers your profit, and sometimes your risk, to the people lending to you.
