Frequently Asked Questions

Understanding Mortgage Payments

What's Included in Your Monthly Payment?

Your monthly mortgage payment typically includes four components (commonly called PITI):

  • Principal & Interest: The main loan amount and interest charged by the lender
  • Property Taxes: Annual taxes divided by 12 months
  • Insurance: Homeowners insurance protection
  • PMI: Private Mortgage Insurance (when down payment is less than 20%)

How We Calculate Your Payment

We use the standard amortization formula used by lenders worldwide:

M = P × [r(1+r)^n] / [(1+r)^n - 1]

Where M is monthly payment, P is principal, r is monthly interest rate, and n is total number of payments. This ensures our calculations match what you'll see from your lender.

Tips for Getting the Best Rate

  • Improve your credit score to 740+ for the best rates
  • Save for at least 20% down payment to avoid PMI
  • Compare quotes from at least 3 lenders
  • Consider paying points to lower your rate if staying long-term
  • Lock your rate when you're comfortable with it
