Play it safe since the deduction ends up being fairly minimal.Lastly, talk to a professional. 

Networking in the DC, MD & VA Area?

However, with the 3 private placement sponsors I have invested with in many deals (soon to be 5), there is an air of professionalism that is palpable.What is your experience?

There aren't many investment vehicles in a TSP aside from the funds the few funds they have.Would it be possible or even legal (I know, seek professional legal advice yada yada) to continue contributing 5% (or more) into my TSP to take advantage of the "free money" being matched by the government and then roll the balance every year into a tax deferred SD-IRA so I can invest that money freely? 

Typically they only want long term tenants, 7 months and longer, they may want a background check to make sure they weren't drug dealers in the past. 

I have decided to do short term rentals of my home in baltimore to travel nurses and other traveling professionals.

If you can't get a professional looking job, it will look like the tenants (novices) painted it, and will lower the desirability of the unit for the next occupants.Keep with neutral, off-white colors, keep it simple--it will broaden the appeal to the greatest number of potential renters.

They are simply free lancers, driving for car shared companies, or becoming Task Rabbiters and Thumbtack professionals.  

What you learned about tenant in their background check or due diligence is for your knowledge and decision making.

My background is in Industrial Engineering, so I nerd out any chance i get to analyze data. :)Looking forward to interacting with the BP community!
