A piggyback loan is essentially a second mortgage on your home and helps you avoid private mortgage insurance (PMI) by covering a portion of your down payment.

Many homebuyers feel so daunted by the idea of saving up for a 20% down payment that they forgo it altogether and end up paying PMI.

If you’re dead set on purchasing a mortgage but don’t have 20% to put down, you may want to consider a piggyback loan.

What is a piggyback mortgage loan?

With a piggyback loan — also referred to as an 80/10/10 loan — you’re essentially getting a smaller second mortgage to cover a portion of your down payment. This smaller mortgage “piggybacks” off the initial mortgage to get you to the amount that you wish to borrow.

This second mortgage is likely to be a home equity line of credit (HELOC) with a draw period of 10 years or a home equity loan, but terms will vary from lender to lender. HELOCs typically have variable interest rates while home equity loans have a fixed rate. Regardless of which second loan type you use, you’ll need to make monthly mortgage payments on your primary and piggyback loans until the balance is paid off.

In some cases, a piggyback loan can also help you purchase a home with a higher value and allow you to avoid getting a jumbo loan.

How does a piggyback loan work?

Piggyback loans are essentially two mortgages plus a down payment.

The first number in the loan represents your initial mortgage, while the second number represents your second “piggyback” mortgage. The third number is your down payment.

How 80/10/10 loans work

While the 80/10/10 structure is the most common way of structuring a piggyback loan, there are alternatives, and those percentages aren’t always the same.

With the 80/10/10 piggyback loan, here’s roughly what you can expect:

How 75/15/10 loans work

Another configuration of the piggyback loan is the 75/15/10 loan. A 75/15/10 loan is often used in condo purchases as it can qualify you for a lower mortgage rate.

In general, condo mortgages with a loan-to-value (LTV) ratio of more than 75% come with higher rates, which can cost more in the long run.

Is a piggyback loan right for you?

A piggyback typically works best for borrowers who:

  • Want a smaller down payment
  • Don’t wish to pay PMI
  • Are buying a condo and looking for a lower interest rate
  • Hope to avoid a jumbo loan

Before getting a piggyback loan, it’s important to crunch the numbers. Make sure the cost of the second loan doesn’t exceed the cost of PMI.

Remember, you can eventually get rid of PMI, so that should figure into your calculations.

Pros and cons of a piggyback loan

The main advantage of a piggyback loan is that it allows you to avoid PMI. While this might seem like a good enough reason to get one, there are also a number of drawbacks to be aware of.

Pros

  • You can put less money down without paying PMI: In general, when you put less than 20% down on a new home, you have to pay mortgage insurance. With the help of a piggyback loan, you can bring less of your own money to the table, but still avoid paying PMI.
  • You can get a condo at a lower rate: Many mortgage lenders charge higher interest rates on condo purchases that have a LTV of 75% or above. If you get a piggyback loan, you might see a lower interest rate by keeping the LTV below 75%. This could potentially save you thousands of dollars in interest over the life of the loan.
  • You can avoid getting a jumbo loan: If you want to buy a higher-value home, you might need a jumbo loan. However, if you don’t want to deal with the requirements that come with qualifying for a jumbo loan, a piggyback loan can help. Since it brings down the amount you have to borrow, it might bring you below the jumbo loan threshold.

Cons

  • They’re harder to qualify for: In many cases, you might have a harder time qualifying for a piggyback loan. Depending on the lender, you’re likely to need a credit score of at least 680, as well as have a lower debt-to-income ratio. This is because you’re qualifying for a HELOC or home equity loan on top of the original home loan — and doing it all at once.
  • They’re more complicated to refinance: You generally need to get permission from your HELOC lender to refinance a first mortgage. As a result, you might need to pay off your piggyback loan before refinancing, or try to work out a situation in which you can refinance both at the same time.
  • You’ll have to pay closing costs on two loans: Remember that a piggyback loan is a separate loan from your primary mortgage. As a result, when you close on your transaction, you need to pay closing costs for both loans. This can increase the cost of your home purchase.

Low-down-payment alternatives to piggyback loans

Borrowers wishing to avoid a 20% down payment but who don’t want to get a piggyback loan have other low-down-payment options.

For example, an FHA loan comes with more relaxed credit requirements and requires as little as 3.5% down. Fannie Mae and Freddie Mac also offer conventional mortgages with low down payment requirements.

Before deciding on a piggyback loan, compare your options and figure out what’s likely to be the best mortgage for your situation. You can also check to see if your state or town has any down payment assistance programs you might qualify for. If you meet eligibility, there are also loan programs such as USDA or VA loans that don’t require a down payment at all.
