I usually have a problem with the contractors.

Have you looked at new build incentives and renting by the room? 

Purchase price: $1,900,000 Cash invested: $2,450,000 The building, “36 South,” is conveniently located next to the Sea Pines Circle and is now home to 48 employees for the Sea Pines Resort.

I purchased them assembled and shipped (didn't trust the contractor to put them together). 

Now I am leaning towards buying land to build within the inner loop and sell.

I'm planning to build one of the preapproved ADU plans provided by the city of Sacramento in my backyard (using a an owner-build permit).

I have a need for several clients for the nw builds we are doing.

The door in question is the front door which is the only entrance to the building for all the tenants.  

Seeing a rent roll, and T-12 or T-24 would be helpful to understand the true Profit of the building.- Although there is no vacancy now, I'd want to see the leases they currently have, especially the commercial lease. 

I would get 3 contractors off of google to come and give you quotes and then go from there
