A median-priced Lewiston, ME home at 6.75% over 30 years, with Maine property tax of 1.24% and $1,300 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$2,381 a month, all in
Principal and interest are $1,821; escrow and PMI add the rest. Over the full term the loan costs $374,855 in interest. Discounted at 5%, buying here has a net present value of $39,081 ($237,314 in today’s dollars).
Within Maine, Lewiston is 2nd of the 3 Maine markets covered here, between Portland at the top and Bangor at the bottom of a 1.93x spread. A state-level median hides most of that.
Lewiston is cheaper than Maine as a whole — $312,000 against a state median of $390,000, roughly 20% below. On a 20% deposit that is $15,600 less to find up front.
Rents here are high relative to prices — a rent index of 0.90 against a price index of 0.80. That combination favours buying sooner, because the payment you avoid is larger relative to the price you pay.

Where these numbers come from
Maine medians come from editorial and are refreshed weekly. The Lewiston 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.
