“The Housing Choice Voucher Program provides "tenant-based" rental assistance, so a tenant can move from one unit of at least minimum housing quality to another. It also allows individuals to apply their monthly voucher towards the purchase of a home, with over $17 billion going towards such purchases each year (from ncsha.org analysis). The maximum allowed voucher is $2200 a month.”
