My question is before I invest or hop in a plane to fly out, what are some of the things you’d look for?

OTOH I also wonder if recent high flying markets like Austin Boise, Vegas, etc., etc. are merely going to “correct” 10-15%, or will they see a 2008-9 GFC correction of 30-40%.

This won’t fly on a long term rental though - you have to intend to occupy the property for at least part of the year.

I've narrowed my list of choices of CPAs/Tax Preparers to these:Basit Sidiqi, CPA (but based in NY, but nationwide service)Lance Lvovsky, CPA (based in FL)Bill Hampton, Tax Strategist and Fee-Only Financial Planner (based in GA, but nationwide service)T Shep Burr, CPA (based in FL)I read what little reviews I could find on the internet for these professionals, but please share the experiences that you've had with them if any.

I would love to be a fly on the wall, if anyone in my local area is willing to allow a “Deal Ride Along”. 

For instance property tax, maintenance, flying to ie.

@Andrew Dincola while you might be able to "get away" with it since you are renting out rooms in your own primary house and thus most likely flying under the radar of any rental permits/inspection requirements (if your local jurisdiction has any) I would strongly suggest not doing it.
