RE rentals don't deal with sales tax or SE.  

I se Quicken home and business and make each property a project. 

It's 2018 and I an option to pickup a handful of properties from a retiring landlord with NW addresses and a few SE address that are 4/2 & 3/2's for around $160K/door.

Also see the "Home Buying Process By State" section on this page, which has an entry for each state and discusses related issues that aren't about the closing per-se (such as customs around wells, heating fuel, environmental, pests, etc.)

I'm looking to house hack or Brrrr in either SE/NE DC or somewhere in PG County or Montgomery County.

Being from California, I am exploring the option of using Turnkey providers for properties in the South/ SE region.

There's isn't a right or wrong answer per se, and of course, everyone's situation is different. 

There have been a lot of posts on here about similar situations, not exactly foster care for special needs children per se, but since the children are disabled and bedridden, I'm guessing there will be many similarities to assisted living facilities.
