If you want to advertise your property for rent as a Section 8 housing, for Sacramento County, go to http://www.shra.org.
This is only good for Sacramento County. Each county has their own website and procedures. When you advertise there, the ad is good for about 14 days. You need to renew it to keep it active. Also, if you find a tenant for Section 8, you need to check their qualifications that they match your home. For example if they are qualified for a two bedroom,they cannot rent your 3 bedroom home. I suggest you do not try to work a deal outside the regulations as there can be fines....
Once you have a tenant that you have qualified through your normal standards, and that has qualifications in Section 8, you need to have an inspection prior to them authorizing funding for Section 8. That can take a month or so to get you in the system.
For more information on the process, you can contact me directly. I have properties that I rent to Section 8 tenants and love it.
