Obviously we consult with structural engineers on bigger or unknown issues, but we would really like to have a better idea of what we're looking at before it gets to that point.

As an engineer, I believe in processes and data.

My father is an Electrical Engineer and has a side business for Home Improvement.

During this inspection, you'll bring as many team members as might be needed (a property manager at minimum and a contractor and/or engineer as needed).

We had multiple walls taken out and had hired a structural engineer to draw plans. 

Potential issues that you might want to look into are zoning, the structural stability of the building if it is multi-story (flooring, people, appliance add a lot of weight per sqft).Depending on what type of construction the warehouse is (Pre-engineered metal building, block, bar joist, or structural) you might have good luck partitioning areas off for contractors, light manufacturing, etc.

Lots of us engineers in here by the way you will notice (M.E. degree for me but I.T. most of my career)

I was thinking I’d be looking at roughly $175k/unit just for the actual direct construction costs, and deconstructing/removing the old buildings, site work, utility connection, holding costs, financing costs, architect/engineer fees, etc. all those ancillary soft costs would be in addition to that $175k/unit but like you I’m in the beginning stages of researching this idea.
