Chattanooga mortgage calculator
A median-priced Chattanooga, TN home at 6.75% over 30 years, with Tennessee property tax of 0.58% and $2,400 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$2,343 a month, all in
Principal and interest are $1,858; escrow and PMI add the rest. Over the full term the loan costs $382,364 in interest. Discounted at 5%, buying here has a net present value of $104,733 ($333,724 in today’s dollars).
Within Tennessee, Chattanooga is 4th of the 5 Tennessee markets covered here, between Franklin at the top and Memphis at the bottom of a 3.17x spread. A state-level median hides most of that.
Rents here are high relative to prices — a rent index of 1.00 against a price index of 0.95. That combination favours buying sooner, because the payment you avoid is larger relative to the price you pay.
Chattanooga is cheaper than Tennessee as a whole — $318,250 against a state median of $335,000, roughly 5% below. On a 20% deposit that is $3,350 less to find up front.

Where these numbers come from
Tennessee medians come from editorial and are refreshed weekly. The Chattanooga figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
