Taxes use NookLocal's estimate at current millage rates, not the stale figure on the MLS. The default rate is the average 30-year rate as of July 2026; insurance is estimated at 0.35% of the price per year. Below 20% down, lenders usually add mortgage insurance, which this estimate doesn't include. Estimate only; verify before relying on it.
