I would make sure whatever you buy the 1st time there are no major concerns i.e roof, septic, furnace, that's pretty much the most expensive things on the list. 

From my standpoint, I want the property & carpets cleaned to my standards - not the departing tenants.  

My husband is a contractor and was able to do a majority of the work.

I have certain school districts that I don't buy in because I think re-sale will be a major problem, and I don't buy in D class areas. 

I also require a higher rent rate (25% - 50% more), the equivalent of three months rent in advance (first/last/deposit), and a mandatory cleaning fee so that I can hire professionals to clean after they depart and still have the deposit available for additional cleaning/repairs.It's a risk but you can make it work if you mitigate the risk to your favor.

Some major capital expenditures were recently done and seems to be in a good area.

I have also tried to get in contact with HR department with local businesses and let them know you have available rental so they can offer/mention to new hires/interns.

I’ve been very happy with my successes, and I’ve been able to accept my failures with calm and been able to limit the damage to where the few loses didn’t have a majority pact on my net worth.

We try to be all into the property for 75% of its value so we can pull out all or at least the vast majority of the money we invested.
