For the office space, one unit of necessity must be converted to office space, and you may also need to give another to the manager.

MH seems to be tenant occupied, not owner occupied, because the assessor's office lists the owner's address as a residential address different from the MH but in same city in Colorado.  

An office secretary of a construction company can do a better PM job than that.

Thank You Mr Harden- So if my office and LLC are located in MD, I can still have properties I am working on and selling in PA?  

Does anyone know if I can finance this as second home since my son will live there and I will actually live there about 4 weeks or so out of the year since I have an office in that town w my W2 job.

I worked in finance for 6 years working along side family offices(billionaire families).

I think a joint limit of say $600k makes more sense and would capture many more households (still a tiny fraction of the population). 

I am renting a gorgeous apartment for $1000 just next to the office and have $30k on my savings account.I am thinking of buying a house for $100k-$130k.

If there is an economic development office where you (want to) invest, they could give you more details!

Once you get to 2 to 3, set up a time to visit their offices and meet the staff.
