Where the numbers come from
Every number on ctbre.com comes from these sources. Each is checked once a day and the site shows new data on the next page view after a source publishes; most publish monthly. The market dashboard shows when each was last checked and updated:
- StreetEasy Data Dashboard — monthly median asking and sale prices, days on market, inventory, sale-to-list ratio, share of listings with a price cut, and asking rents, by neighborhood. We show a three-month average of the monthly medians, because a single month in a small neighborhood can swing on a handful of sales.
- NYC Department of Finance rolling sales on NYC Open Data — closed sales from deeds recorded with the city (ACRIS). We include co-ops, condos and one- to three-family homes sold for more than $150,000, and omit unit numbers.
- Zillow Home Value Index by neighborhood — the typical home value, smoothed and seasonally adjusted. Zillow names differ in two places: Midtown East uses Zillow’s Turtle Bay index and Midtown West its Hell’s Kitchen index.
- Botensten Properties International’s own listings and closings come from its StreetEasy listing feed through the Bridge Data Output API.
Neighborhood boundaries follow StreetEasy’s definitions for market data and the city’s 2020 Neighborhood Tabulation Areas for the map, so edges are approximate. Finance Department neighborhood names are mapped to ours (for example, Greenwich Village–West is the West Village).
The “market” label compares three signals to Manhattan overall — sale-to-list ratio, days on market and the share of listings with a price cut — and calls a market tilted only when at least two agree.
Guides are drafted from these numbers with AI assistance, checked automatically against their sources, and approved by Charles Botensten; the editorial policy explains how. Nothing here is legal or tax advice.
