What the dashboard measures
The citywide summary uses all 328 unique qualifying MLS records. Neighborhood results use source-provided coordinates joined to the City of Rochester neighborhood layer. Filter the population to duplexes, triplexes, or four-unit properties, then map sales, median price, median price per square foot, median source-defined days on market, or deduplicated Updegraff Group Realty involvement.
The comparison window is January 1 through September 9 in both years. The latest closing contained in the 2026 export was September 4, so the retrieval date, query end, and latest included record remain separate.
Read movement as a question—not an answer
A higher median does not establish appreciation. Each year contains a different mix of unit counts, locations, conditions, occupancy situations, financing, and property characteristics. A lower closing count does not identify whether supply, demand, seller expectations, credit conditions, or data timing caused the movement.
Annual price and market-time measures require at least five observations. A UGR proportional share requires at least 20. Transaction counts remain visible at smaller sample sizes so readers can see why a result was withheld.
Source and geography controls
The population is limited to Town/City = Rochester, property type Multi-Family Residential (2–4 units), status S-Closed/Rented, and one row per unique MLS Number. Individual listing records and addresses are not republished.
Official City and association polygons can overlap. Each area is calculated independently, so neighborhood totals cannot be added to reproduce the citywide count. MLS property type is not independent proof of legal unit count or current Certificate of Occupancy.
MLS data attribution
Based on data from the New York State Alliance of MLSs for January 1 through September 9 in both 2025 and 2026, using these criteria: Town/City = Rochester; status S-Closed/Rented; property type Multi-Family Residential (2–4 units); one row per unique MLS number; duplex, triplex, and four-unit views use the Total # Apts field; neighborhood views match source coordinates to official City polygons.
The export was retrieved September 10, 2026. The latest included 2026 closing is September 4, 2026. Small-sample price and market-time metrics are withheld below five observations.
