Click any question below to expand quick answers, formulas, and expert tips.
Do extra mortgage payments always go directly to principal?
You must specify "Principal Only" on your lender’s payment portal to ensure extra funds are not held in escrow or credited toward future interest payments.
Is it better to pay off a mortgage early or invest in the stock market?
If your mortgage interest rate is high (6.5%–7.5%+), paying it down provides a guaranteed, risk-free, tax-free return equal to your mortgage rate.
