Wow.....your best bet is to go to the Section 8 office and see if they keep an inventory of ready to go homes. Second, google property management firms in your area and call them with this question. Lastly, if the rental is from an individual, then ask them the question. Many individual homeowner/landlords do not understand section 8 or gone through the required education.
I have several under section 8 in Memohis through a property management firm. Get on the phone...you'll find somthing.
