I've a couple questions:1) Is this how the process works for correcting existing addition to the house?

The college park area houses college students from all over the nation in addition to a significant military presence.

Depending on where I buy the unit, I may be planning to occupy the unit for the shortest time possible then rent out all of the units.Any additional advice is greatly appreciated regarding best places to find listings for what I’m looking for, a good real estate agent that’s investor friendly, good markets to choose from to generate cash flow, cash on cash return, etc.Any information is welcome and I‘d love to hear what you all have to say.

Some of them have property owners who are retiring or some are motivated to sell due to life situations like divorce or death in the family or a critical illness.

My investment thesis is here: https://www.biggerpockets.com/blogs/10553/79631-se...I've begun selling off my portfolio due to the headaches and hassles of management, in addition to getting a little older and wanting to press hard into passive vs. active investing.

It has been my experience and observation that the relationship between the Landlord (LL) and the Property Manager (PM) is critical and cannot be overstated...but it is also extremely precarious.  

I'm happy to answer your questions or provide additional information.
