Rosebank & Porter Heights housing market, September 2021

The median sale price was $575,000 in September 2021; there is no comparable figure a year earlier.

A seller’s market, by the usual rule: 1.1 months of supply in September 2021 (under four favors sellers, over six favors buyers).

Homes that sold in September 2021 had been on the market 4 days on average, a fast pace; from listing to closing took 40 days on average.

Every figure is read from RealTracs’ own export for the Rosebank & Porter Heights map area — the Snapshot report for the month and the five-year Timeline files for all eight data sets, monthly and 3-, 6- and 12-month rolling. Files are kept as downloaded, with a manifest of download names and checksums, so any number here can be traced to its file. The only arithmetic on the page is labelled where it appears: a change worked out from two monthly figures, and the ranges in the “earlier years” sentence. Months with fewer than 10 sales are flagged as small samples and their price figures switch to RealTracs’ rolling medians. The summary and the questions are filled from fixed sentences — no forecasts, no advice. “Favors sellers / balanced / favors buyers” follows the usual rule of thumb for months of supply: under four, four to six, over six. Days on market: under 30 is called a fast pace, over 60 slow.
