Mortgage borrowing in the United States is structured around long-term amortizing loans, typically 15 or 30 years, with either fixed or adjustable interest rates. The standard amortization formula M = P[r(1+r)^n] / [(1+r)^n - 1] determines how each monthly payment splits between principal repayment and interest.
The US mortgage market is among the most standardised in the world. Freddie Mac and Fannie Mae set conforming loan limits ($806,500 in most counties for 2025) and purchase most conventional loans. FHA loans (insured by the Federal Housing Administration) require as little as 3.5% down but add mortgage insurance premiums. VA loans (for veterans) allow zero down payment with no PMI.
Property taxes vary dramatically by state and county, ranging from under 0.3% annually in Hawaii to over 2% in New Jersey, and are typically escrowed into the monthly payment alongside homeowners insurance. Private Mortgage Insurance (PMI) is required when the down payment is below 20% and can be cancelled once equity reaches 22%.
The US is one of few countries where 30-year fixed-rate mortgages are widely available and government-backed (via Fannie Mae/Freddie Mac). Most other countries offer fixed rates only for 2–10 year terms before requiring refinancing. This makes US mortgage calculations simpler over the full loan term but means US homeowners carry more long-term interest rate risk on adjustable products.
