(RECAP: The Arlington County Board today approved a $16.5 million Affordable Housing Investment Fund (AHIF) loan to help AHC Inc. purchase Serrano Apartments. Current rents for 239 of the 280 units are considered affordable. But as the Pike continues to redevelop, there’s no guarantee those market-rate units will remain affordable. As a condition of their loan, AHC has agreed that 196 of the units will become Committed Affordable Units, contractually obligated to remain affordable for 60 years. Fifty-six will be affordable at 60 percent of AMI and 140 will be affordable at 80 percent of AMI. Ten will become supportive housing units for Department of Human Services clients. The remaining 84 units will continue to be rented at market rates.)
