What Is a Piggyback HELOC and Why Should You Consider It?

Aug 25, 2025

For many homebuyers, navigating the world of mortgages can feel overwhelming. Questions about down payments, mortgage insurance, and financing often crop up as you plan one of the largest purchases of your life. One tool that can make the process more manageable—and potentially save you money—is a piggyback HELOC, or Home Equity Line of Credit. 

This flexible financial strategy not only helps you avoid extra costs like private mortgage insurance (PMI), but also provides options to manage your finances more effectively. When you pair this with the personalized service and competitive rates at Leading Edge Credit Union (LECU), you’re setting yourself up for a smoother and financially advantageous home-buying experience. 

Here’s everything you need to know about piggyback HELOCs and how LECU can support you every step of the way. 

What Is a Piggyback HELOC? 

A piggyback HELOC is a second loan taken alongside your primary mortgage. The most common setup is an 80-10-10 structure. This means:

  • 80% of the home’s purchase price is financed with a traditional mortgage. 
  • 10% is covered by a HELOC (the piggyback loan). 
  • 10% comes from your down payment. 

A HELOC functions as a line of credit secured by the equity in your home, allowing you to draw funds as needed during a set borrowing period. Unlike fixed-term loans, HELOCs provide flexibility, as you only pay interest on the amount you actually use. 

Why Use a Piggyback HELOC? 

Piggyback HELOCs are typically used to avoid private mortgage insurance (PMI), which is required when your primary loan covers more than 80% of the home’s value. PMI can add hundreds of dollars to your monthly payments without contributing to your equity. By keeping the primary mortgage at or under 80% of the purchase price, you avoid this additional cost. 

Other common reasons to consider a piggyback HELOC include managing cash flow, covering unexpected expenses, or leveraging financial flexibility early in your homeownership. 

Is a Piggyback HELOC Right For You? 

Piggyback HELOCs aren’t for everyone, but they can offer significant benefits if used strategically. Here are a few scenarios where this type of loan may make sense:

  • Low Available Funds for a Larger Down Payment: If you can’t put 20% down but want to avoid PMI, a piggyback HELOC can bridge the gap. 
  • Anticipated Lump Sum Income: Planning to receive a large sum (e.g., from a bonus or sale of another property)? A HELOC allows flexible repayment without locking money into rigid terms. 
  • Financial Flexibility: Unlike a mortgage, a HELOC line of credit can be accessed again during the borrowing period, making it a valuable tool for emergencies or renovations. 

Benefits of a Piggyback HELOC 

1. PMI Protection

The biggest draw of a piggyback HELOC is the ability to avoid private mortgage insurance. PMI is often required for conventional loans exceeding 80% of the purchase price, yet it provides no added value for the borrower. By leveraging a HELOC to cover part of the purchase, you sidestep PMI entirely, keeping more money in your pocket over the life of the loan. 

2. Lower Monthly Payments

Because PMI doesn’t contribute to equity or principal, skipping this cost means your monthly payments go toward building equity or maintaining cash flow. 

3. Financial Flexibility

HELOCs are revolving lines of credit, meaning you can borrow as much or as little as you need (up to your limit) and repay on flexible terms. This makes them ideal for handling unexpected expenses like emergency repairs or additional purchase-related costs. 

4. Potential Tax Benefits

If the funds from your HELOC are used for home improvements, the interest you pay might be tax-deductible. (Always consult a tax professional for specific advice tailored to your situation.) 

5. Faster Path to Home Equity

With a HELOC, you have more control over how quickly you build equity in your home. By avoiding PMI and strategically managing your repayment, you can accelerate equity growth and reduce your long-term financial burden.
