Understanding the Piggyback Loan Strategy
In the complex world of mortgage financing, the piggyback loan strategy stands out as a unique option that can offer significant advantages. But what exactly is a piggyback loan? Simply put, it involves taking out two loans simultaneously to purchase a home. This strategy is often used to avoid paying Private Mortgage Insurance (PMI) when the down payment is less than 20%.

How Piggyback Loans Work: A Closer Look
The piggyback loan typically follows an 80/10/10 structure: 80% of the home’s price is financed by the primary mortgage, 10% by a second mortgage, and the remaining 10% by your down payment. This structure helps borrowers skirt PMI, which can add 0.5% to 1% of the loan amount annually. For a $400,000 home, that’s an additional $2,000 to $4,000 per year.
Primary Loan
The primary loan is your standard mortgage, typically a 30-year fixed-rate loan. As of May 2026, the average rate for such loans is around 6.75%, according to Freddie Mac PMMS.
Secondary Loan
The second loan can be a home equity loan or a HELOC. Unlike the fixed-rate primary loan, the second loan often has a variable rate, which might be higher. For instance, a HELOC might start at 6.20%, but it can fluctuate based on the market.
When to Consider a Piggyback Loan
Choosing a piggyback loan depends largely on your financial situation and home buying goals. Here are some scenarios where they might be beneficial:
- Avoiding PMI: If you can’t put down 20% but want to avoid PMI, a piggyback loan can be a smart choice.
- High-cost Areas: In regions with high home prices, like Washington D.C., this strategy can help keep monthly payments manageable without resorting to jumbo loans.
- Leveraging Lower Rates: If the second mortgage offers a lower rate than PMI would cost, it’s worth considering.
Cost Analysis: Real Numbers Matter
Let’s break down the costs using a hypothetical example. Suppose you’re buying a $500,000 home:
- Primary Loan: $400,000 at 6.75% over 30 years. Monthly payment: approximately $2,594.
- Secondary Loan: $50,000 at 6.20% over 10 years. Monthly payment: approximately $560.
- Total Monthly Payment: $3,154.
Comparatively, a single mortgage with PMI would cost more. Assuming a PMI rate of 0.8%, the PMI alone adds $333 monthly, totaling $3,427. Over 10 years, a piggyback loan saves you nearly $32,760 in PMI costs.

| Flexibility | High | Low |
| Refinancing Complexity | Higher | Lower |
Frequently Asked Questions
What exactly is a piggyback loan?
A piggyback loan is a second mortgage taken alongside your primary mortgage, commonly structured as an 80/10/10. This means 80% of the home price is covered by the primary mortgage, 10% by the piggyback loan, and the remaining 10% by your down payment. This setup helps avoid PMI (Private Mortgage Insurance).
How does a piggyback loan affect refinancing?
When refinancing, a piggyback loan can complicate the process as both the first and second loans need to be addressed. It's crucial to consider the interest rates of both loans compared to current market rates, which are around 6.75% for a 30-year fixed mortgage as of May 2026.
Are piggyback loans only for avoiding PMI?
While avoiding PMI is a primary benefit, piggyback loans can also help if you lack a full 20% down payment. They can be advantageous in high-cost areas where home prices exceed conforming loan limits, allowing you to borrow without paying jumbo loan rates.
What are the risks of a piggyback loan?
The main risks include variable interest rates for the second loan, which are often higher, and the complexity of managing two simultaneous loans. If the home value decreases, you might owe more than the home is worth on the combined loans, which can affect refinancing options.
Can first-time buyers use piggyback loans?
Yes, first-time buyers can use piggyback loans, especially in states like Connecticut and Nevada with specific programs. However, they should weigh the pros and cons, considering local grants and assistance programs that may offer more straightforward financing options.
