Introduction: The HELOC Strategy That Saves You Big
If you’re an investor or homebuyer trying to minimize out-of-pocket costs and boost long-term ROI, there’s a savvy strategy you should know about: the piggyback HELOC. This lesser-known method can help you avoid private mortgage insurance (PMI) and reduce your monthly payments—all while preserving flexibility and liquidity.
What Is a Piggyback HELOC?
A piggyback loan—often called an 80/10/10 loan—involves using a traditional first mortgage for 80% of the purchase price, a HELOC for 10%, and then contributing 10% as a down payment.
- 80%: First mortgage (conventional loan)
- 10%: HELOC (second loan)
- 10%: Your down payment
This structure keeps your primary loan at or below the 80% loan-to-value (LTV) threshold—avoiding PMI—while allowing you to put down less than 20%.
The Real Cost of PMI—and Why You Should Avoid It
PMI is required on most conventional loans when your down payment is below 20%. While PMI rates vary, they typically range from 0.5% to 1.5% of your loan amount annually. For example:
- $400,000 loan × 1% PMI = $4,000 per year, or $333/month
That’s a significant drag on your cash flow—especially for real estate investors focused on maximizing returns.
How Piggyback Loans Lower Your Monthly Payments
By eliminating PMI through a piggyback structure, you cut unnecessary monthly expenses. Even though the HELOC comes with its own payment, it’s often interest-only for the first 5–10 years and has a smaller principal. The result?
- Lower monthly payment
- Greater tax-deductible interest (consult your CPA)
- Faster equity building
If you choose a lender like Figure, known for fast digital HELOC approvals and competitive rates, you could close in as little as 5 days, giving you an edge in competitive markets.
Piggyback HELOC Example: Investor Scenario
Let’s say you’re buying a $500,000 duplex:
- First Mortgage (80%): $400,000 @ 6.75%
- HELOC (10%): $50,000 @ 9.5% (interest-only)
- Down Payment: $50,000 (10%)
Without PMI, your monthly costs could be $300–$500 lower compared to a 90% LTV loan with mortgage insurance. Over 5 years, that’s $18,000–$30,000 saved—money you can reinvest into your next deal.
Pros and Cons of Piggyback HELOCs
✅ Pros:
- Avoid PMI (save $300+ monthly)
- Lower upfront capital requirement
- Preserve liquidity for renovations or reserves
- Interest may be tax-deductible
⚠️ Cons:
- HELOCs often have variable interest rates
- Two monthly payments (more complex management)
- Requires strong credit (typically 680+ FICO)
- Closing costs can be higher due to two loans
Who Should Use This Strategy?
A piggyback HELOC is ideal for:
- Real estate investors preserving cash for renovations or reserves
- House hackers who want to reduce upfront costs
- Buyers in high-PMI markets where insurance premiums are especially steep
- Move-up buyers who don’t want to drain equity from their current home
This strategy is especially powerful when used in hot markets where speed and cost efficiency matter.
How to Set Up a Piggyback HELOC
- Check your credit: Aim for 680+ FICO (720+ preferred).
- Compare lenders: Look for those offering 80/10/10 structures—Figure and select credit unions are great starting points.
- Run the numbers: Use our HELOC Calculator to compare monthly payments with and without PMI.
- Get pre-qualified: Ensure your first mortgage and HELOC lenders can close together.
Tip: Some lenders will coordinate the piggyback setup, streamlining the process.
Final Thoughts: Leverage Smarter, Invest Bigger
Piggyback HELOCs give investors and buyers a tactical advantage: lower monthly costs, faster equity growth, and the freedom to invest elsewhere. It’s a smart workaround to an often frustrating requirement—PMI—without the steep down payment hurdle.
