I have a lot of experience in renting to Section 8 voucher holders. There is not a specific place where all section 8 rentals are listed however, these are your best bets:
– Local newspaper classifieds. The ad will usually start with “Section 8 Welcome”
– Usually your local Section 8 office will have a listing of properties in their office. Most housing authorities provide a book or website where landlords can post their listing.
