Gap Financing Explained: Closing the Gap Between Loan and Cost

Most deals I see fall apart don't fall apart over bad numbers. They fall apart because the investor can't cover the gap between what the lender will fund and what the deal actually costs.

Here's the thing nobody explains clearly: gap financing isn't one product. It's a category, and the pieces inside it behave very differently.

A gap loan plugs a specific, smaller shortfall, something like a down payment or a rehab overage. These usually run 6% to 12% interest, smaller amounts, shorter terms.

A bridge loan is a different animal. It finances an entire interim purchase, like buying your next property before you've sold the current one. First position, secured by real estate, typically 8% to 15% interest, and can run up to 12 months.

Here's a scenario to make it concrete. Say you're buying a fix and flip at $320,000, with $60,000 in rehab and $25,000 in closing and holding costs. Total cost is $405,000. Your hard money lender covers 75% of purchase plus some rehab draws. That leaves you short around $80,000 for the down payment, remaining rehab, closing costs, and reserves.

A lot of investors default to finding a private lender to fill that with a second lien on the property. Worth knowing before you go that route: most serious hard money and DSCR lenders won't allow an unapproved second position on their loan, and it can blow up your closing if the lender finds out late. A private lender's own finances can also change days before closing, and now your deal is dead.

The other approach is stacking non property secured tools instead. Think an unsecured term loan, 0% business credit cards during the promo window, maybe a HELOC on an existing asset. All of it sits outside the deal property's collateral, gets repaid at sale or refinance, and doesn't touch the first lien your hard money lender is holding.

Some things to actually think through before you use any of this:

Do you have two realistic exit paths, not just one?

Can the deal absorb these payments if the timeline slips or costs run over?

Are you disciplined enough to track multiple payment schedules at once without losing track?

Gap financing costs more than a bank loan, full stop. The question that actually matters is whether the deal's spread between all in cost and ARV still supports a solid profit after those costs. On a thin margin deal it's probably not worth it. On a deal with real room, it can be what gets you to the closing table instead of watching it get outbid.

I work with these structures daily through Gap Funded, happy to answer questions on how the stacking side works if anyone's running the numbers on a deal right now.
