For investors looking for investments $20 million and under, Tucson ranked number 4 on the list of small/middle sized markets. A larger driver of the demand for multifamily in Tucson is the attractive year-over-year (YOY) average rent growth of 9.1%. The shortage of affordable and traditional housing in Tucson also fuels apartment rental demand. With construction costs tripling on certain building materials, housing development has slowed down drastically over the past 12 months. In a market with the typical average residential for sale inventory at about 6,000 listings, fewer than 1,000 homes are for sale. This shortage has led to increased demand for multifamily living, which in turn has driven down Tucson’s vacancy rate.
