How the 80-10-10 Piggyback Works — Step by Step
Apply to TWO lenders simultaneously
You need a primary mortgage lender (for the 80% first loan) AND a HELOC lender (for the 10% second loan). Often the same lender offers both — but shop separately for best rates.
First mortgage: 80% of purchase price at conventional rates
At exactly 80% LTV, you qualify for standard conventional rates with NO PMI. Rate: roughly the same as any conventional 30-year rate. No PMI surcharge.
Second mortgage: 10% HELOC at close (simultaneously)
The HELOC funds simultaneously with the first mortgage at closing. This HELOC is immediately drawn to 10% of purchase price to cover the gap.
You bring 10% cash to closing
You contribute 10% down payment as normal. Total funded: 80% (first mortgage) + 10% (HELOC) + 10% (your cash) = 100% of purchase price.
Pay down the HELOC aggressively
The second mortgage has no prepayment penalty. Many buyers pay off the 10% second loan within 3–5 years. Once it's paid, your combined payment drops significantly.

Piggyback Loan FAQ
What is an 80-10-10 piggyback loan?
An 80-10-10 piggyback loan is a home financing strategy using two simultaneous loans to avoid PMI with only 10% down. Structure: First mortgage: 80% of home price (conventional, no PMI). Second mortgage (piggyback): 10% of home price — typically a HELOC or home equity loan. Down payment: 10% cash. Total: 80% + 10% + 10% = 100% of purchase price. The key benefit: By keeping your first mortgage at exactly 80% LTV, you avoid Private Mortgage Insurance (PMI) entirely. On a $400K home, PMI typically costs $100–$300/month. The second mortgage (10%) does have its own interest cost — usually variable at Prime + 1–2%. The math question is: does the second mortgage cost less than PMI? Often yes — especially in the first years when your loan balance is high.
What are the different piggyback loan structures?
Three main piggyback loan structures: 80-10-10 (most common): First mortgage 80% + Second mortgage 10% + Down payment 10%. Best for: buyers with exactly 10% down who want to avoid PMI. 80-15-5: First mortgage 80% + Second mortgage 15% + Down payment 5%. Best for: buyers with only 5% down who want to avoid PMI. Second mortgage cost higher (15% vs 10%). 80-20 (rare today): First mortgage 80% + Second mortgage 20% + 0% down. Was common pre-2008. Very limited availability today — requires excellent credit and income. Which structure is right for you depends on: How much cash you have. The cost of PMI on your first loan. The HELOC/second mortgage rates you qualify for. How quickly you plan to pay off the second mortgage.
When does piggyback loan beat paying PMI?
Piggyback loan wins over PMI when the second mortgage cost is lower than PMI cost. Example — $400,000 home, 10% down: Option 1 — One 90% LTV loan: Loan: $360,000 at 7.0% = $2,394/month P&I. PMI: $180/month (0.6% of loan). Total: $2,574/month. Option 2 — 80-10-10 piggyback: First mortgage: $320,000 at 7.0% = $2,129/month. Second mortgage (HELOC): $40,000 at 8.5% = $283/month. No PMI. Total: $2,412/month. Monthly savings: $162/month with piggyback. Annual savings: $1,944. The piggyback wins until the second mortgage is paid off OR until you'd hit 80% LTV on the single loan (when PMI would drop off). Key: Compare the second mortgage rate to your PMI rate. If HELOC is 8.5% and PMI is 0.6% of $360K = $180/month, the HELOC costs $283/month for the $40K — higher monthly BUT you build equity in the second mortgage, whereas PMI is pure insurance premium.
What are the risks of a piggyback loan?
Piggyback loan risks to understand: Variable rate second mortgage: Most piggybacks use a HELOC (Prime-based variable rate). If Prime rises, your second mortgage payment rises. In 2022–2023, this increased HELOC rates by 4%+ rapidly. Two loan qualifications: You must qualify with both lenders simultaneously. DTI calculations include both payments. Complexity: Two closings, two servicers, two payments. Less flexibility if you need to refinance later. Home value decline risk: If home values drop and you're at 100% LTV, selling is difficult. Closing costs on two loans: You pay closing costs on both loans simultaneously. Risk mitigation: Pay down the second mortgage aggressively (no prepayment penalties on most HELOCs). Set up auto-pay for both. Consider a fixed-rate second mortgage instead of a HELOC if you want rate certainty. Have a plan for when to pay off the second mortgage entirely.
