A standard US mortgage payment is commonly referred to as PITI (Principal, Interest, Property Taxes, and Homeowners Insurance), with HOA fees added for condos and planned communities.
Compounding Convention: Standard US fixed-rate mortgages use discrete monthly compounding where periodic interest rate = annual nominal rate / 12. Federal disclosures under Regulation Z govern how APR and repayment terms are communicated to borrowers.
Taxes & Insurance: Property taxes vary widely across states (e.g. Hawaii ~0.3% vs New Jersey ~2.4%). PMI applies if down payment is below 20%.
