Methodology
Every market figure is Redfin’s, for homes that sold (all home types), exactly as Redfin publishes it. Towns use the Redfin Data Center series for the municipality itself, three months combined (each figure shows its period), so small towns have enough sales to mean something. Counties use the latest single month. Change vs. last year is Redfin’s own figure. Charts show 24 months of median sale prices.
Redfin publishes some townships only on their own Redfin page, as a recent snapshot: those towns are labeled with the date we read the page, prices are rounded as Redfin shows them and days on market is an average. Where Redfin publishes no figure for a town, the page says “Not published”. We never estimate, borrow a neighbor’s numbers or use ZIP code figures for a town.
Effective tax rates, general tax rates, average assessments and average residential tax bills are published by the NJ Division of Taxation for each municipality. Payment estimates use the 30-year fixed rate from Freddie Mac’s Primary Mortgage Market Survey.
Towns with fewer than 10 sales in the period are marked “few sales”: one sale can move their medians a lot.
Every module shows when its data is from. Market data is marked out of date 60 days after its month ends, the 24-month history after 60 days, mortgage rates 10 days after their survey date, and tax data after April 30 two years after its tax year, when the next year's figures are overdue. Estimates are for planning only, not legal, tax or lending advice.
