Using 2017 ACS 1-year microdata, Enterprise Community Partners estimated the total number of unsubsidized affordable units that were in SMMF properties. First, the total number of units affordable at different income levels was calculated. Income levels were calculated as percentages of the local median renter income across the country. The median renter income was calculated based on all renter households in the metro area or state (for households living in non-metro areas). Units were considered “affordable” if they were offered at gross rents at or below 30% the specified income level. Table 1 depicts the total number of affordable units available at each income level, broken down by the number of units in the structure:

Among the estimated 189,428 rented units in SMMF (2-49 unit) buildings in Miami, 23% (43,364) are affordable at 80% of renter median income, 40% (75,070) are affordable at the renter median income, and 59% (111,062) are affordable at 120% of renter median income.
These totals include subsidized SMMF units. The National Housing Preservation Database (NHPD) was used to determine how many of those units were not receiving any subsidy and were still affordable to lower-income households, nationally and in Atlanta and Miami (again using the Atlanta 5-county region and Miami-Dade County as geographic boundaries).
