Frequently Asked Questions

What is a blended mortgage rate?

A blended rate is the weighted average interest rate across two loans (e.g., a first and second mortgage). It helps you understand your true cost of borrowing when using a piggyback loan structure.

Why would I use two mortgages?

A common strategy is an 80/10/10 loan: 80% first mortgage, 10% second mortgage, 10% down. This avoids PMI while keeping a lower blended rate than a single high-LTV loan.

Is a HELOC the same as a second mortgage?

A HELOC (Home Equity Line of Credit) is a type of second mortgage with a variable rate and revolving credit. A traditional second mortgage has a fixed rate and fixed payment schedule.
