Maintaining high occupancy levels in apartment complexes can be an ongoing challenge, especially in highly competitive markets. This is why affordable, government-subsidized housing can be a great option for investors. If the properties are in the right location, occupancy can consistently run at 100%, with waiting lists for new tenants. Not only are these properties full, but delinquencies are a non-issue because most of the rents are paid by the government. Ira Fishman of North Loop Investments owns over 400 units of affordable housing, mostly in Chicago and the surrounding areas.
