Frequently Asked Questions
How is a mortgage payment calculated?
Monthly payment = P[r(1+r)^n]/[(1+r)^n-1], where P is the loan principal, r is the monthly interest rate, and n is the total number of payments. For a $280,000 loan at 6.5% for 30 years: r=0.065/12, n=360, payment = $1,770.
What is the 28/36 rule?
The 28/36 rule is a guideline for affordable housing. No more than 28% of gross monthly income should go to housing costs, and no more than 36% to total debt (housing + car + student loans + credit cards).
How much should my down payment be?
Traditional advice is 20% to avoid PMI (Private Mortgage Insurance). However, many loans allow 3-10% down. FHA loans require as little as 3.5%. A larger down payment means lower monthly payments and less interest over the life of the loan.
