Then you need to account for soft expenses like Vacancy/turnover, maintenance, and capital expenses.

Further, running a very quick and simple valuation based on $900 rents, 8% vacancy, 25% op exp margin, and a 9% cap rate, I'm coming up with an ARV of around $83k, so I'd pass if I were you unless you can get a much lower purchase price.

My suggestion would be to buy a place to be a mid term rental and experiment with short term during the vacancy gaps. 

A family needs a washer and dryer in the house, if you don't add I think you'll take a hit on rent and take longer when there's a vacancy. 

Are you reserving for cap ex, maintenance & vacancy?

Vacancy and maintenance factors should be higher than for Class A or B.

You've only owned it six months, so you probably haven't dealt with vacancies, maintenance, or capex, but you should be setting money aside for those things.Your partnership agreement (if you have one) should address exit options.

For example, I stay 99% occupied with my MTRs - the only vacancies are planned vacancies when I need a couple of days for a turnover.

Regarding all the calls you are getting: wholesalers know this is the worst time of year for vacancies.

You'll find much greater difference in $$$$$ by refining your location/rehab/vacancy strategies instead of worrying about "how much it costs to borrow money" in this environment.Nearly all of my clients are more concerned with a simple and headache-free funding process, than the "lowest rate."
