Frequently asked questions
What is the 28/36 rule for home affordability?

What does PITI stand for in mortgage payments?
PITI represents the four components of a monthly mortgage payment: Principal, Interest, Property Taxes, and Homeowners Insurance (plus Private Mortgage Insurance if down payment is under 20%).
