As a real estate agent and a landlord, I would go to the Shra website / landlord. However, in order to be a "section 8" landlord, you need to attend a 3 hour class which goes over all the information on how to list your home, and the procedure of section 8. It is very informative and they cover all the regulations you need to do in order to be section 8 approved. I met some other landlords and I am actually thinking of attending again to refresh my memory. But what Ed said, can be true. You get the money monthly, but you are other problems with the tenants such as noise disturbance, selling illegal drugs (yes, believe it or not), it is harder to evict them.
By the way, you can post your rental on their website for free. It is a bit tricky to find the housing available section. When I posted there, I actually spoke to many people that were on the waiting list for section 8 who was looking for affordable housing. However, I have a rental currently available and I posted on craigslist, trulia's rental section and rentals.com.
Hope this helps.
