The first residents of a seniors housing development, let’s call them the “Founders”, may reveal unique characteristics of the building itself. Typically, initial rents for a new building would be based on rents per square foot of similar buildings in the market and cost. But “Founders” have a first choice of units and may reveal preferences as to particular units within the building. These choices or preferences become lost as the development fills and trends toward sustaining occupancy. Capturing initial data on the preferences revealed by Founders may provide a guide to setting prices as various units turn over in subsequent years.
