PITI (Principal, Interest, Taxes, and Insurance)The four components that make up a typical monthly mortgage payment. Principal reduces the loan balance, interest is the cost of borrowing, taxes are property taxes (often collected through escrow), and insurance includes homeowners insurance and any mortgage insurance. PITI is the figure lenders use when calculating debt-to-income ratios.Points (Discount Points)Upfront fees paid to the lender at closing in exchange for a reduced interest rate. One point equals 1% of the loan amount. Paying points (also called buying down the rate) can lower your monthly payment and save money over the life of the loan, but it increases your upfront costs. Points make the most sense for borrowers who plan to stay in the home for a long time.Pre-ApprovalA lender's conditional commitment to lend a specific amount based on a thorough review of the borrower's financial information, including credit history, income, assets, and debts. Pre-approval involves a hard credit inquiry and carries more weight than pre-qualification. A pre-approval letter shows sellers that the buyer is a serious, qualified candidate. Learn more in our pre-approval guide. Pre-QualificationAn informal estimate of how much a borrower may be able to borrow, based on self-reported financial information. Pre-qualification typically does not involve a hard credit check and is less rigorous than pre-approval. It provides a general idea of buying power but does not carry the same weight with sellers.PrincipalThe original amount of money borrowed in a mortgage, not including interest or other charges. Each monthly payment reduces the principal balance. The principal, combined with the interest rate and loan term, determines the total cost of the mortgage.Private Mortgage Insurance (PMI)Insurance required by lenders on conventional loans when the borrower's down payment is less than 20% of the home's value. PMI protects the lender if the borrower defaults. It can be cancelled once the borrower reaches 20% equity in the home, either through payments or property appreciation.
