Frequently asked questions.
How is a monthly mortgage payment calculated?
Monthly mortgage payments are calculated using the standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n – 1], where P is the principal loan amount, r is the monthly interest rate, and n is the total number of monthly payments.
What is a good down payment percentage for a home?
A common recommendation is 20% of the home value to avoid private mortgage insurance (PMI). However, many programs allow as low as 3-5% down payment.
How does interest rate affect total mortgage cost?
Even a small change in interest rate significantly impacts total cost. For example, on a $300,000 loan over 30 years, a 1% rate increase can add over $60,000 in total interest paid.
