Personally, I cannot afford to waste time on low ballers when there are so many other intelligent, qualified, legitimate and rational investors to work with.  

What they look at is called the debt service coverage ration, which basically is an analysis of the mortgage payments versus the property's income (measures as net income from the property divided by the loan payment).

They provide MLS listings where the turnover to the REI is as expensive or even more expensive than the MLS listing2 - Charge so much for their wholesale fee, they make more money than the REI3 - Are terrible at analysis...as in no idea how, or would use anything as a comp or rational to make their poor deal sound good.

So this fear that he would "move in and demand money back" does not seem a rational one, at least where I am (that's not to say I'd rent to someone unqualified, but prepayment certainly does not seem to me a negative).  

Staying where you are is neither rational or logical.As for flipping long distance there are probably more horror stories associated with that scenario than any other aspect of real estate investing.

I'll keep the good, long term tenants who appreciate the fact that S-8 provides good housing for rational tenants.

People are sheep, thinking of them as all logical, rational, and educated investors is foolish.Thankfully, when they crash, it makes for good deals for the sharks, condors, vultures, or whatever predatorial term you want to assign to the rest of us :)

Take a look at debt to income ration.

Could be, but I don't think so, and I believe my desire to buy large-scale assets is rational.

Just as in the '40's when capital had to attract new labor with "benefits" because of price and wage rations.
