If she went to buy a house and applied for a mortgage, I think the lender would say the same thing aka you don't qualify until you get this removed from the credit report.

I personally think it really depends on how much value will it add to the property and if the town will allow it. 

I absolutely think it was the right investment because of that but not once did anyone guarantee that this would work out.

I think it's very dependent on the property and market. 

I don’t think you’d slide the substitution of credit past the newest of new realtors.

When I really think about it though, I'm so grateful to not be managing my property day-to-day. 

Are there any other key features you think I should be factoring in?

I'm thinking about investing into section 8  housing in STL and I'm new to this game.

Do you think they're worth the investment, or do most buyers still prefer in-person showings? 

There are markets that have built in "gotchas" like the rising cost of insurance in coastal FL, regulations in much of the west coast states and property taxes in Texas; however, the deal itself is the most critical factor.
