Real Estate Commissions and Homebuying

Abstract

We construct a model of home search and buying in the U.S. housing market and evaluate the commission paid to homebuyers' agents. In the model, as in reality, homebuyers enjoy free house showings without having to pay their agents out of pocket. Buyers'agents receive a commission equal to 3% of the house price only after a home is purchased. We show this compensation structure deviates from cost basis and may lead to elevated home prices, overused agent services, and prolonged home searches. Based on the model, we discuss policy interventions that may improve housing search e¢ ciency and social welfare.
