PITI
Also called: Principal, interest, taxes, and insurance
Principal, interest, taxes, and insurance — the four parts of a typical monthly mortgage payment, and the number lenders use to measure affordability.
Principal and interest repay the loan. Property taxes and homeowners insurance are usually collected through an escrow account. Mortgage insurance and HOA dues aren't in the acronym, but lenders include them in your housing cost, and so should your budget.
When comparing homes, compare full PITI, not just the loan payment. Two houses at the same price can have very different tax bills and insurance costs.
