In 1970, there were 6.5 million low-cost rental units in the US and 6.2 million low-income renter households with 300,000 units available to households. By 1985, the number of low-cost units had fallen to 5.6 million and the number of low-income renter households had grown to 8.9 million, a disparity of 3.3 million units.
In 2022, the National Low Income Housing Coalition reported that the State of Florida has a shortage of 435,879 rental units available and affordable to low income renters. 82% of renters at extremely low income (30% AMI) are extremely cost burdened, paying more than 50% of their income on housing costs; 57% of households within the 30-50% AMI range are extremely cost burdened. Even some of the middle income (80-120% AMI) households are extremely cost burdened (7%).
