The challenge with the FHA guidelines is the self sufficiency test.

then you take the state test and the federal test to get your NMLS registration..

The way to find it starts with testing and challenging yourself and your system.  100% during hot time is one thing.

You need to always be changing with the market, testing and poking to see what marketing works better and what does not work at all. 

I tend to do a quick dirty look at a building like JW with price per door, but after that sniff test, I quickly like to understand $Cost/SF and $rent/SF.The way I look at a single family, 2-4 units, or a 20 unit is all different, but the end result is still ROI or IRR (over time). 

If you want more cash flow deals you may want to look outside of Boston and test out some new markets where you're hitting closer to the range of returns you're looking for. 

Quote from @Joseph Bushnell: I'm testing out the idea of building a data center and I was wondering if anybody has heard of owning the building and having a third party operate the data center itself.  

Ultimately it will depend on the property (banks perform stress test-debt ratio)-but I think 5 year term is what I found so far.

For example, if the area is rural you might wish to have the house inspected, the well tested, and the septic system inspected by separate services.

Either way, I wouldn't put the AirBNB terms of service to the test.
