I have zero experience in real estate, but I can honestly say nothing has gotten and held my attention more than this subject.I am a management & program analyst with the federal government right now.

I have worked in Fl. as a government and private contractor so I know the prices there.

My sister does not declare depreciation on her rental because she is "as good or better at filling out the taxes as most CPAs" and "the government always gets paid."

After that's paid, I'd do the same with the government student loan.  4.  

The information you need should be available on line, All state/city landlord tenant regulations and codes should be readily available with a simple search.You need to know all the codes governing your business so you may as well start studying now.

Dover seems to be a good opportunity with colleges, Delaware government offices and an Air Force base. 

Mobiles in a community are subject to lot lease rates and community rules that you are responsible for similar to a condo except governed by the community owner.

Zillow and other sites will have some too of varying quality.Municipal governments may have properties tagged as rentals or owner-occupied if they conduct regular inspections, but that is inconsistent in Pennsylvania.  

For example here in San Antonio we have a strong government backing with all the different military bases and also lets not forget about the greatest championship team in the world, The San Antonio spurs lol.

There is a low income government housing neighborhood 1/2 mile from there.
