Housing Market Dynamics and Demand

Michigan's housing market, however, remains constrained by a persistent supply-demand imbalance. From 2012 to 2022, the state permitted only 494 homes per 1,000 jobs created, lagging behind national trendsHome | Michigan Housing Data Portal^[6]. By 2021, the statewide vacancy rate had plummeted to 1.9%, far below the 5% threshold considered healthy, signaling acute competition for housing.
