Frequently asked questions

What is PITI in a mortgage?

PITI stands for Principal, Interest, Taxes, and Insurance. These are the four standard components that usually make up a monthly mortgage payment.

How much down payment do I need?

While 20% is ideal to avoid PMI, many programs allow as little as 3% or 3.5%. However, a lower down payment results in a higher loan balance and monthly payment.

What is Private Mortgage Insurance (PMI)?

PMI is a monthly fee required by lenders if your down payment is below 20%. It protects the lender in case of default.

Should I choose 15 or 30 years?

30-year loans offer lower monthly payments but cost more in total interest. 15-year loans have higher payments but save a massive amount of interest and build equity faster.
