Pricing a co-op without an exact measure of square footage then boils down to pricing the number of rooms that are being sold. It is like using an abacus to do your taxes. Really, it is.You should look at pricing strategy like this: our jobs as brokers is to create the market for your home. Price is just one part of this process. We want to simply price your home at the number that is going to attract the most buyers (ideally, in the shortest period to create competition and scarcity). Where most sellers go wrong is by trying to dictate to the market where their home should sell at. Telling the market your home is worth a premium is usually the worst way to get a premium. Price your property at the number that is going to bring you the most qualified buyers and they will offer you what it is worth.
