I'm exploring the idea of renting out property to Section 8 tenants in St.

There's a market for all that in the area.

The lender wont talk to you without the owners written authorization, and the lender does not own the property to sell it to you. 

Negotiated through the seller.

I think that the tax perks from having a rental make this more attractive than it might initially seem, but I have only done some quick internet searches, so I could very well be overestimating the upside and underestimating the downside??
