The optimal markets for rental revenue and occupancy rates might fluctuate based on the current economic climate and demand for housing. Strong employment growth, population expansion, and low vacancy rates are typically associated with increased rental revenue and occupancy rates. In cities with several colleges or military posts, rental housing is frequently in great demand. New York City, San Francisco, and Los Angeles are cities with historically robust rental markets in the United States. Seattle, Denver, and Austin are three other cities with thriving rental markets in recent years. However, prior to making investing selections, it is essential to conduct research on current market circumstances and trends.
