Investing in real estate is a reliable way to build equity and financial security. The most common path to homeownership includes taking out a mortgage loan. Some savvy home buyers opt for piggyback loans in order to avoid paying private mortgage insurance (PMI). As appealing as that sounds, there are a few considerations you should weigh before taking out a piggyback loan.

Piggyback Loans, Defined

Before you can understand what a piggyback loan is, you should know what a second mortgage means for a borrower. A second mortgage is a loan with rights that are subordinate to a first mortgage. For instance, if a person has two mortgages on a home that they want to sell, the first mortgage would get paid off before the second mortgage.

Typically, borrowers will opt for a second mortgage later on in the first mortgage loan life to pay off credit card debt or another financial hardship. Piggyback loans, also known as 80/10/10 loans, are different.


Simply defined, a piggyback loan is the term used by mortgage lenders when a borrower takes out a first and second mortgage at the same time. Borrowers often get piggyback loans to avoid paying PMI or higher interest rates, or to avoid taking out a jumbo loan.

The first mortgage will typically cover 80% of the purchase price as a traditional 30-year fixed rate mortgage without the usual private mortgage insurance. The second mortgage, the piggyback, will cover 10% of the home price, usually as a home equity line of credit (HELOC). The remaining 10% of the home price is a cash down payment by the borrower.

Things To Consider Before Taking Out A Piggyback Loan Or 80/10/10 Mortgage

As with most financial decisions, the right choice boils down to your current financial wellness and how to best meet your goals. Let’s take a look at some of the pros and cons of piggyback loans.

Pros Of Piggyback Loans

Avoiding PMI

One of the most common reasons to get a piggyback loan is to avoid paying private mortgage insurance (PMI), which protects the lender from default. It’s cheaper for the homeowner to get two mortgages, and the interest is usually tax deductible. We recommend checking with your tax advisor before making such a big financial decision.

When you have 20% equity or more in the home, you are legally allowed to tell your lender to drop PMI. Otherwise, the lender is required to drop PMI when you’ve reached 22% equity in the home.

Lower Down Payments

A piggyback mortgage can also be a way to finance more than 80% of the home’s purchase price (also referred to as 80% loan-to-value or LTV).

For instance, if a home buyer only has enough for a 5% down payment, they can get what’s known as an 80/15/5. The “80” refers to the first mortgage which finances the first 80% of the home’s purchase price. The “15” refers to the second mortgage which finances another 15% of the purchase price. The “5” is the borrower’s 5% down payment.

There are two basic permutations to this: 80/15/5 or 80/10/10. However, some lenders do allow an 80/20 option in which the second mortgage covers the rest of the purchase price with no down payment.


Getting a piggyback loan can be a nice convenience to home buyers. Because a piggyback mortgage closes at the same time as the first mortgage, you don’t have to go to two closings, sign two separate sets of paperwork or pay two different closing costs. If your primary lender doesn’t offer piggyback loans, they’ll likely recommend another lender that they have an established relationship with.

Sometimes, the second loan can be structured in a way that gives the homeowner practical use. For instance, if the second loan is a home equity line of credit, the homeowner may draw from the loan to use for, say, home improvements.

Piggyback loans may also be structured to allow interest-only payments. This means that for a specified period of time, you only have to pay the interest, though you can add as much principal on top of that as you wish.

This option gives homeowners the added flexibility in what they can do with their money. They may divert it toward their 401(k) or other financial investments, use it to pay off high-interest credit card debt, or save it for a rainy day.

Avoiding Jumbo Loan Interest Rates

If you’re in the market for a more expensive home, you may be able to avoid the lending limits of jumbo loans with a piggyback loan. You’ll benefit from lower interest rates on the first mortgage.

Cons Of Piggyback Loans

On the flip side, piggyback mortgages come with plenty of drawbacks that can turn a borrower off. Here are just a few:

  • Higher interest rates: The second mortgage is usually financed at a higher mortgage rate than the primary mortgage since it’s tied to short-term interest rates. In fact, these rates may outweigh the cost of PMI over time.
  • Higher monthly payments: Second mortgages have a shorter loan term than first mortgages and are usually confined to primary residences. That means higher monthly mortgage payments and residence-type restrictions.
  • Amount limits: Second mortgages are also limited to loan amounts no higher than $100,000. However, some lenders allow more. Other lenders, like Rocket Mortgage®, do not offer piggyback loans.

The Bottom Line

Piggyback loans have several benefits, but whether or not getting one is right for you is ultimately your decision. Taking out a piggyback loan can strain your lines of credit, so you’ll want to be sure that the savings are worth it in the long term.

If you’re buying a home and aren’t sure if you need a piggyback loan, it’s best to talk to your mortgage banker. While we don’t offer piggyback loans, Rocket Mortgage is here to provide you expert advice on your lending needs and to help .
