Mortgage Calculator — Estimate Your Payment in Jackson, TN

Your monthly payment is made up of four components, often called PITI: Principal (the portion reducing your loan balance), Interest (the lender's cost for the loan), Taxes (your annual property tax divided by 12 and held in escrow), and Insurance (homeowner's insurance, also escrowed). If your down payment is less than 20%, a fifth line item — PMI — is added until you reach 20% equity. The calculator above breaks all five out individually so you can see exactly where your payment goes.

Twenty percent is the benchmark that eliminates PMI and gives you the best rate options, but it's not required. FHA loans allow as little as 3.5% down, and conventional loans can go as low as 3% for qualifying buyers. With Jackson's median home around $270,000, a 20% down payment works out to roughly $54,000 — a meaningful number. Many buyers in this market put down 5–10% and plan to eliminate PMI once they've built equity. A Prosper agent can connect you with local lenders to explore what makes sense for your situation.

Private Mortgage Insurance is required on conventional loans when your down payment is less than 20% of the purchase price — meaning your loan-to-value ratio exceeds 80%. It protects the lender, not you, and typically costs between 0.3% and 1.5% of your loan amount annually. The good news: PMI isn't permanent. Under the Homeowners Protection Act, lenders must automatically cancel it once your balance drops to 78% of the original purchase price. You can also request cancellation at 80% if you can demonstrate the value through a new appraisal.

A 30-year mortgage spreads your payments over twice the time, resulting in a lower monthly payment but significantly more interest paid over the life of the loan. A 15-year term carries a higher monthly payment but typically a lower interest rate, and you'll build equity much faster. On a $216,000 loan (20% down on a $270K home) at current rates, the difference in total interest paid between a 15- and 30-year term can exceed $100,000. Use the term toggle in the calculator above to compare the monthly payment difference side by side.

Your credit score is one of the most significant factors a lender uses to set your interest rate. Borrowers with scores above 740 typically qualify for the best available rates. Dropping from a 760 to a 680 can increase your rate by 0.5% to 1% or more — which on a 30-year loan translates to tens of thousands of dollars in additional interest. If your score needs work, it's often worth taking 6–12 months to pay down balances and resolve any errors before applying. Even a modest improvement can move you into a better rate tier.

Yes. The Tennessee Housing Development Agency (THDA) offers the Great Choice Home Loan program, which provides 30-year fixed-rate mortgages at below-market rates for eligible first-time buyers. The program also includes down payment assistance of up to 6% of the loan amount through the Great Choice Plus option. Income and purchase price limits apply and vary by county. Madison County buyers should check current THDA limits directly, as they're updated periodically. A local lender or Prosper agent can walk you through the qualification criteria and help you determine if you're eligible.
