While Craigslist is wonderful to search for rental properties, you can also contact local real estate agencies for assistance. Many agencies and property managers have numerous properties that they may not post on Craigslist. No property owner may discriminate based on Section 8 status. Most landlords, management companies, and agencies have an application process that will look at references, credit history, and employment. With a voucher, oftentimes the voucher can weigh more than employment as the rent will be subsidized. Provided you meet the landlord's specifications in these basic areas, you'll have a home in no time!
Best of luck in your search for a new home!
