Although I'm not sure about that because I know how much they get abused. 

I find/buy the house that meets the needs of the tenants ie. near a bus line, no stairs, etc.

Friends of mine who came from successful parents might build something bigger than their parents or decay into alcohol and drug abuse.

I would suggest to make them put the utilities under their own name (if possible), because even if you put it as included in the rent, unless you charge a good amount, they will abuse it (turn the heater that extra temperature, take those extra 5 minutes in the shower, etc.).

For example: I am not someone who used to abuse substances, I am someone who overcame a great obstacle that few do.

I think there are two issues that seem to concern RE investors:Restrictions in underwriting/loan terms- DF discourages abusive loan terms (neg amortizing, balloon payments, 40 year schedules, etc).

About a month ago after working weeks of 16 hour days and a 2 week trial of trying to put a guy in prison for sexual assault I began thinking about giving up my day job. 

Just like the gross rent multiplier (GRM), however, it gets abused.

IMO, houses like these that are in much need of some love after years of abuse often have many other hidden issues once you begin rehab.  

I also think the program gets abused and can lead to dependency, but that's another story entirely...
