Frequently Asked Questions

How is my monthly mortgage payment calculated?

Your monthly payment is calculated using the 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 number of payments.

Should I choose a 15-year or 30-year mortgage?

A 15-year mortgage has higher monthly payments but you'll pay significantly less interest over time. A 30-year mortgage has lower monthly payments but costs more in total interest. Choose based on your budget and financial goals.

How much should I put down on a house?

Putting down 20% avoids PMI (Private Mortgage Insurance) and typically gets you better interest rates. However, 5-10% down payments are common for first-time buyers. The right amount depends on your savings and financial situation.
