Well that's large enough to attract a wide variety of people IMO.

This entire 10 wide strip is physically owned by the City of San Diego...the dimensions can vary (the example below is an 18' dimension), and the conditions may not be exact, but if the meter is within this area then it isn't encroaching on your lot at all.

Also, I would like to know generally for contracts, legal advise etc. can i use a lawyer nation wide?

Smaller lots, land, tough condition houses, junked single wides... etc...almost never. 

Also, to move our machines from the front yard to backyard, the door entry must be at least 7-foot wide.

I want to go into this eyes wide open, and be as well informed as possible. 

You'd be in a better position to view properties and could focus on developing one strong team instead of sprinkling your efforts over a wide area.

However, in looking on Airbnb and Vrbo in Bay St.Louis for example most calendars are wide open.

However trying to find local banks, credit unions even nation wide lenders that arent stuck at 30% 35% ltv whether it is a refi or loan. ( and will loan in the llc name) is there anyone out there in a similar situation that could recommend what and where to be connecting with more investor focused lending.

Closing costs include a wide range of items such as an appraisal fee, survey fee, attorney fees, title search fee, escrow fee, mortgage insurance depending on the loan, HOA fees, title insurance, property tax, recording fee, etc.
