Cooperative/Condominium Comparables

Department of Finance


Cooperative and condominium comparables

You may think of the market value of your co-op or condo as the price you could sell it for on the open market. However, state law requires the Department of Finance to value residential cooperative and condominium buildings as if they were rental apartment buildings. This means that we look at the income and expense statements of rental buildings that have similar characteristics to determine your condo or co-op building’s market value.

Comparable properties are chosen based on the number of units, size, age, distance, and number of stories. There is never a perfect match. To account for any differences, adjustments are made to the income and expense of the rental buildings used as comparables for your property. For example, if your co-op is older than the rental building that is the best comparable match in your neighborhood, we use a computer model to adjust the rental comparable to produce a more accurate value for your building. You can view the comparable properties that were used to value your co-op or condo below.
