Mortgage Guides for Homebuyers
The short version of things buyers ask about.
📚 Educational Content: These guides explain mortgage concepts for informational purposes. They are not financial advice, not a substitute for consulting your lender, and not an offer to lend. Always verify terms with your actual lender or financial advisor before making borrowing decisions.
Down payment assistance programs
Many states and some lenders offer grants or low-interest second loans to cover part of your down payment or closing costs. FHA, USDA, and Fannie Mae's HomeReady program are the most common entry points for home loans. Use a mortgage calculator to see how different down payment amounts affect your monthly payment and PMI.
How to remove PMI from your home loan
On a conventional mortgage, PMI drops off automatically once your loan balance hits 78% of the home's original value, and you can request removal at 80%. FHA loans work differently — mortgage insurance usually lasts the life of the loan unless you refinance out of FHA entirely. Check your amortization schedule to see when PMI will drop.
Extra payments explained: reduce your interest
Every extra dollar goes straight to principal, which reduces the total interest you're charged on all future payments. Use our mortgage calculator to see how even modest extra monthly payments can cut years off your 30-year loan and lower your total interest paid.
Biweekly mortgage payments
Paying half your monthly payment every two weeks works out to 26 half-payments a year — equivalent to one extra full monthly payment. This strategy reduces your total interest paid and shortens your loan term. See the impact on your amortization schedule with a mortgage calculator.
Should you buy mortgage points?
A discount point costs 1% of your home loan amount upfront in exchange for a lower interest rate—usually about 0.25% lower. Calculate the break-even point: if you'll hold the mortgage long enough for monthly savings to recoup the upfront cost, points make sense. Use a mortgage calculator to compare interest rates with and without points.
Fixed vs. adjustable interest rates
A fixed interest rate never changes for the life of your home loan, keeping your monthly payment predictable. An adjustable-rate mortgage (ARM) starts lower but can rise after an initial period. Fixed rates are the safer default. Use a mortgage calculator to see how different interest rates impact your monthly payment and total loan cost.
