Questions people ask
What's included in a monthly mortgage payment?+
Usually PITI: principal, interest, property taxes and homeowners insurance, plus PMI if you put down less than 20% and HOA fees if you have them.
When does PMI go away?+
Under the Homeowners Protection Act, PMI on a conventional loan ends automatically when your balance is scheduled to reach 78% of the home's original value. You can ask your lender to cancel it once you reach 80%.
Is a 15-year or 30-year mortgage better?+
A 15-year loan has a higher monthly payment but usually a lower rate and far less total interest. A 30-year loan keeps payments lower; you can still pay extra to finish early.
