Double check, but it seems like a pretty cut and dry breach of contract case. 

I have conducted a  dry listing to see if I could get interest and was able to 8 applications in 24 hours before I removed the listing at a rate of 700$ per room.

But with that drying up and the glut of buyers and aspiring wholesalers there are way more buyers than deals.  

Buying a duplex as a straight up investment that cash flows 10k in 4-5 years when you are facing 300k in debt is like asking a towel to keep you dry from a fire hose. 

This provides you a clearer line of sight on financing, a little more cut & dry vs commercial with experience being less of a requirement. 

Dry rot possibilities and fire protection systems.

If it was my money only in the deal, and if she pays on time, gets along with the neighbors, doesn't call me to come fix every towel drying bar that comes loose from the wall - and her "hoarding" doesn't cause an insect or rodent problem, I would probably let her stay for $325 because I'm too nice and i like long term tenants even at lower rates.Maybe she would become my first Section 8 renter ever if Section 8 paid more than $325 in that area. 

Like I said, the question stemmed from a conversation in jest I had with another investor, but it got me thinking and I got pretty much zero Google results for "Section 8 in class A areas" (shocker). 

The smaller your market the more it makes sense to have a couple skill sets otherwise you could go through some long dry periods.  

You float the room with it and when it dries you have a level surface to tile.
