Homeless Veteran Families Act This bill updates the Department of Veterans Affairs per diem payment calculation for entities furnishing services to homeless veterans to include funding for a minor dependent. The rate for per diem payments is the daily cost of care as estimated by the grant recipient or eligible entity. This bill would expand the per diem payment amount for a homeless veteran who has care of a minor dependent to the daily cost of care plus, for each minor dependent, an amount that equals 50% of such daily cost of care.
