Quote from @Dan Grove: Some combination of cash to seller, closing costs, repairs, construction, paying off arrears, assignment fees, commissions.   

I guess it's just too many factors to consider and it easy to get overwhelmed and cannot get accurate info and estimation when I conduct analysis (ex. property tax rate, insurance, maintenance fee, rent, repair, closing cost, etc.) 

That aside, If it were me I'd get a professional estimate of what repairs would cost, and make the decision to keep or sell based on that. 

Quote from @Alecia Loveless: @Natalia Perlova Absolutly no to the Sunday repair.

And that’s with zero vacancy, zero repairs, zero capex.

Zoning says that it is a repair service shop, excluding automobiles, any idea if leasing out storage space would be permitted?

Look at the contractor company doing the repairs.

Stuff that may be a head scratcher as to "well why did they not mention this at all, I mean, holly-cow this changes everything". 

I like new construction since there isn't any deferred maintenance and the properties should be relatively maintenance free for the first couple years (although it's good to include maintenance/repairs in your pro forma and maintain reserves just in case). 

I thought I could solve the vagrant problem by buying and repairing the buildings.
