Upstate NY - storefront, residential, and....what else?

[Brandon Cohen]

Hey All - an off-market deal was just put in front of me and I'm looking for options/ideas that could make it work.  

Mixed use building.  small commercial space on ground floor, 2 vacant apartments upstairs, crumbling barn in the back.  

The owner wants $60k for it, the two apartments are move in condition and rent for $600 & $750/month, taxes are $4k/yr.  The rentals would cover any loan however I would pay cash up front and look to re-fi.  My thought would be to knock the barn down and put in self storage.  My question, is there pre-fab self storage companies that can come in and plunk down a set up, and what sort of cost would I be looking at if so?  Secondly, what to do with the commercial space up front?  

Open to any and all suggestions, thank you!
