Call expired/FSBOs (if you have the stomach for it). 

Getting things working in the Poconos can be a bit like eating a bowl of broken glass for breakfast, if you can't stomach that I'd recommend just buying somewhere else.

A stomach issue I had for several months turned to a burst gallbladder that had gangrene going into my blood stream.

Putting aside the challenges in the new consumer loan regs, I don't have the stomach for working with such buyers/borrowers.  

Another thing I would look at is your risk profile and how much you can reasonably stomach.

It's hard to stomach the thought of doing a beautiful remodel, only to have a bunch of short term tenants go in there and slowly trash the place. 

You can also invest in Assisted Living Facilities if you have the stomach for it (Very stressful, high staff turnover, liability magnet) and it will be a fairly profitable investment for a while yet with the aging population we have and while 500K won't get you up and running in most parts of California for the ALF business, you could quite possibly operate a 16 bed facility in Arizona without any debt with that money and usually net yourself six figures annually in returns as long as you are able to keep the property occupied.

As for the debt, with STR it is a bit limiting. but if you can stomach a long-term rental for a time first, the rules for "departing residence" will let you use 75% of the lease to offset the PITIA of THIS property on your DTI for the new primary purchase.

If not, do you have the stomach for repositioning?

I agree with the previous statements... the only reason I could stomach the hours of analyzing and visiting "no-good-deals" was the perspective provided on BP.
