Every 4+ unit residential building sale in Rockland County on the OneKey MLS from October 2025 to September 2026, plus what is for sale as of October 15, 2026. Prices per unit, taxes per unit, and a rent-based yield estimate built from what apartments actually rented for last month.
Rockland County's five townships. The rent column is the median rent signed last month for 1- and 2-bedroom apartments in that township, the rent that drives the yield estimate.

"—" means no sales, or too few leases in that area to measure. Where an area had fewer than 3 leases, the county median of $2,488 is used for the estimate.
Each bar is one building sold in the last 12 months, colored by township. The dashed line is the county median.

About the yield estimate. The gross rent multiplier (GRM) is the price divided by one year of rent, assuming every unit rents at the township's typical 1–2 bedroom apartment rent. It is a quick screening number, not an appraisal: actual rent rolls, vacancies, unit sizes and expenses (taxes, insurance, heat, repairs) decide the real return. A lower GRM means more rent per dollar paid.

How we made this report. Rockland County listings on the OneKey MLS with 4 or more residential units: quadruplexes (Residential Income) and multi-family buildings of 5+ units (Commercial). Sold means a closing from October 2025 to September 2026; for sale means active on October 15, 2026. Buildings listed as multi-family with fewer than 4 units are excluded, and mixed-use buildings are included only when listed as multi-family. Taxes are the annual taxes on the listing.
