suggestion: buy it for $1 take out a loan for 40k pay off you sister have your mother hold a second for the remainder and become a first after the 40 is paid off.suggestion: take equity out on 1 of your other properties for the 40k and have your mother reassign the 300k loan to you!

So analyzing MHP and other large scale multifamily is different than commercial retail spaces.

With an inflexible full time job, i am not sure how to pull this off..Any suggestion? 

These are great suggestions!

Any suggestions?

Should I just randomly pick a few cities in the midwest and work with a realtor, or are there some suggestions on specific cities and resources to help hone in?

I would suggest going to the planning and zoning department, and pulling the building permits to see who is building and where.

Also what would you suggest is the best list provider?

Also appraisals or BPOs would be requested by a buyer when they are making an offer, so I would suggest not doing it ahead of time, unless Maryland law requires it (again something any Maryland Realtor should know).

I would suggest that you read the full regulations and anticipate that they city will be enforcing everything.
