Rochester Investment

Market methodology

A closing, a side, and a dollar of volume are not the same thing.

Brokerage production is frequently overstated because reports count dual-sided transactions, duplicate cross-listings, lease records, or list prices inconsistently. Our Rochester research separates the measures.

Updated: Working methodology — September 9, 2026

Unique property-sale closing

A deduplicated property sale identified by its address, closing date, and final sale price. A dual-sided closing is still one property sale.

Represented transaction side

One listing-side or buyer-side representation. When the same brokerage represents both sides, the methodology may count two sides—but must say so explicitly.

Dollar measures

  • Unique-closing property value: each final sale price counted once
  • Side-based represented volume: a dual-sided final sale price may be counted once for each represented side
  • List price is never added to sold price to create sales volume

Current review

The available office MLS history is being reconciled for lease-like records and apparent duplicate cross-listings. Final public totals will follow that classification review. Off-market closings will remain a separately documented dataset.
