.) - There's an unfinished second floor that is currently considered "attic" space.

I would speak to the Sewage Enforcement Officer to determine if the drain field needs to be moved and if there is space for an alternate location and if the new location would pass a perc test. 

Small park 22 spaces (16 owner occupied-3 park owned-3 vacant lots) with a 30 space mini storage also. $415k asking price. 

I mean the space is crazy!  

Bedrooms and bathroom upstairs, and living room, dining room, kitchen and laundry on first floor, and access to basement.Building needs some repair since its old, but being that its fully rented I assume there aren't any major problems or it would not have passed inspection.Mortgage on it was taken out for 118k back in Dec. 2011.City taxes are $7273 annually and school taxes are $5510 annually.For the attached building:a mortgage was taken out for $27700 back in April 2010.City taxes are $3602 annually and school taxes are $3322 annually.So I was thinking of buying both to have 6 units and a commercial space to rent out for a convenience store or something of the sort.

He is loud and has a hard time with personal space.

One of my wife's uncles was in charge of one of the properties which is zoned for commercial/residential, it is a 1708 Sqf office space/small warehouse on .36 acre lot.Which with some research it can be split into 2 lots.He let the property go to the dump, needs a new metal roof, and gutted, replace plumbing/bathroom, replace electrical etc...Now my wife’s Aunt is in charge of the estate and she was the one who approached me.She said they will "sell" me the property for $30K (estimates from Real estate agent say property is worth $43-$53K in current condition) Which then I could clean the property up and try to resell with the improvements.Now if I did replace the roof make the inside look nice and clean the overgrown landscaping I was told (real estate agent) it could get about $60K, but there are back taxes and liens on the property as well.Plus closing cost for when I sell it, I have run the numbers and it seems that I would MAYBE make $3000-$9000 conservatively.But I am real concerned over the fact that it is used as an office/commercial, and wouldn't this limit buyers?

Also has so many start ups that now they can rent space from me in my downtown buildings.Some of the things I see posted on BP just kill me. 

(Gross) or is it the actual floor space of the living unit (Net)If its the net area- is there any way to clarify the gross area ?

This seems to be a disconnect - there are high income residences surrounding underutilized retail and office spaces.
