East Hill housing market, December 2021

The three-month rolling median sale price was $505,000 in December 2021; there is no comparable figure a year earlier. The rolling figure is used because only 1 home sold in the month.

A seller’s market, by the usual rule: 0.95 months of supply in December 2021 on a three-month rolling basis (under four favors sellers, over six favors buyers). The rolling figure is used because only 1 home sold in the month.

With 1 sale in December 2021, a monthly average would mislead; over the three months to December 2021 homes that sold had averaged 8 days on market, a fast pace.

Every figure is read from RealTracs’ own export for the East Hill 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.
