What is a piggyback loan?

An 80/10/10 structure: first mortgage at 80% LTV (conforming, best rate), second mortgage for 10%, and 10% down. Used to keep the first mortgage below conforming limits and avoid both jumbo pricing and PMI.

When is a piggyback better than a jumbo loan?

When the jumbo rate premium plus blended second mortgage cost is less than the conforming rate. The math shifts frequently — run the numbers with current rates before deciding.

Are jumbo loans harder to qualify for?

Yes. Tighter credit requirements (typically 700+ FICO), larger reserves (12+ months), more conservative DTI limits, and full documentation. Portfolio lenders hold jumbo loans and set their own guidelines.
