This bill establishes a pilot program to expand the escrow accounts for families receiving housing assistance. The program allows eligible entities to establish interest-bearing escrow accounts for families, placing amounts equal to increases in rent attributable to increases in earned income. Families can withdraw funds after ceasing to receive welfare assistance or in other specified circumstances. Eligible entities must provide detailed information to families and may opt out. The bill includes provisions for rent calculation, timeline, study, waivers, and termination of the pilot program. It also authorizes appropriations for technical assistance and program evaluation.
