Alternatively, my more specific is Malden and Everett which has direct access to trains and buses and you can find 2 families for the same price range and an occasional three family with work needed.

Suggest you go the electric route--less or  no maintenance costs, and when repair is needed, inexpensive compared to most gas fired boilers or furnaces.I would also have a small natural gas wall space heater installed somewhere on the main living floor (not in bedrooms) just in case of power outage and / or for supplemental heating.  

I have access to capital and a strong knowledge of residential (as well as other types) construction.I'm from Mechanicsburg, Pennsylvania (which is just south of the capitol city of Harrisburg).Would welcome any suggestions for finding deals. 

I’ll have easy access to new listings, market reports, email alerts that I can customize.

(although I personally could never share such a small space.)Not sure how any different law in your area (if there is one)  could be allowed since it would violate federal law.

I have a tenant from hell who will go to any length to prevent access to the property. 

Again thank you for the feedback I bought a 16 space park in Oregon for 80k  it was run down old single wides  a house etc..

I own a commercial space (business condo)I used to operate a business in the space, but several years ago sold the business and leased the space back to the new business owner (about 3 years ago). 

Just depends on access with a concrete truck.

Make sure the lightning is spot on, and make sure you have some curtains for your space for some added color.
