In the College Park/Adelphi/Hyattsville/ Riverdale area I would look for a 5 bedroom with atleast 2 full bathrooms and preferably 3 with 1 of those bathrooms being a master bathroom or a full bathroom in the basement. 

Also if perhaps there is a chance the title company would pay me out, I would much prefer that!

If it is still within the statute then it is likely the HOA attorney would prefer to collect in rem against the property (and new unit owner) rather than in personam against you.

The level of detail you wanted to see is a matter of preference, but that will also entail more effort and time. 

@Rosa Lepore I always prefer to leverage.

Another way to learn is by going to local meetups and interacting with people and asking questions.

As i understand your needs, you're looking for cashflow, C class or better, preferably multifamily, and the property needs to be around $550K to complete the 1031.

I prefer leasehold mobile home parks

Usually my Landlords would much prefer to pay out a TIA and keep the rents high, as this keeps the building value up.

The primary air vent going outside preferred because Highefficent furnaces are sealed combustion.
