A piggyback loan—often called an 80/10/10 or combination mortgage—is a clever way to buy a home with less cash up front. Instead of a single mortgage plus private mortgage insurance (PMI), you take out two loans at closing: one for 80 percent of the home’s value and a second for 10 percent. You then cover the remaining 10 percent with your own down payment. This structure lets you sidestep PMI, which can add hundreds to your monthly payment, and keeps your main mortgage under the conforming loan limit so you avoid the stricter requirements of a jumbo loan.
Beyond skipping PMI and jumbo-loan hurdles, piggyback loans let you stretch your cash reserves. In a standard 80/10/10 setup, you’re only putting 10 percent down instead of 20. Some lenders even offer an 80/15/5 arrangement, where you contribute just 5 percent and borrow 15 percent as your second mortgage. You can use either a fixed‐rate home equity loan or a home equity line of credit (HELOC) for that second piece, giving you flexibility in how you tap into additional funds without dipping into savings for closing costs or renovation projects.
Of course, there are trade-offs. Your second mortgage usually comes with a higher, sometimes variable interest rate, so your payment could rise if rates climb. You’ll also pay closing costs on both loans, which can eat into the savings you’d hoped to gain from avoiding PMI. And if you need to refinance down the road, juggling two separate lenders and loan products can complicate the process. It’s important to run the numbers carefully—compare combined payments and fees side by side with a single conventional or jumbo loan scenario.
If you’re intrigued by the piggyback strategy, start by shopping around for both primary and second-mortgage lenders. Look at interest rates, loan terms, and qualification standards, and be prepared to supply documentation for both applications at once. As you gather quotes, don’t forget to weigh low-down-payment alternatives, too: FHA programs require as little as 3.5 percent down, Fannie Mae and Freddie Mac’s Conventional 97 loan needs only 3 percent, and VA loans offer zero-down financing for qualifying veterans. With a clear understanding of your options, you’ll be ready to choose the path that lets you move in sooner—without overextending your budget.
