Novogradac published updated unit financing estimates of enacting a minimum four percent LIHTC , which estimates more than 126,000 additional affordable rental homes would be created or preserved from 2020 to 2029.  The estimate is far higher than previous Novogradac research suggested—just 66,000 units over an earlier ten-year period—because Novogradac updated the baseline it uses for this research to account for the increased use of private activity bond authority for multifamily housing bonds. The record-low floating rate for bond-financed Housing Credit properties also contributes to the large difference between the current and previous estimates of the impact of a minimum rate.
