How much will you spend in repairs on a 1920's house with renters ? 

The $100-$300/month amount is just a generalization - but the point is, on a monthly basis you don't see a huge income per property - and you also have to absorb repair expenses and such as well.   

Each of the 5 warehouses on this campus will require updates (construction of offices/bathrooms, roof repairs, paint, siding repairs, new penetrations for doors, updates to electrical, insulation, and extension of water and sewer). 

I’ll also amortize large items like roof over 20 yrs, and then add $100/mo/unit for general repairs.

Well even if the rent is equal to the mortgage, you'll still be in the negative after repairs, CapEx, vacancy, etc.Why would you specifically be thinking of investing at a negative cash flow?

Cash Partnership 50/50 on both the purchase and repairs.

I would just not move forward with scheduling a showing until/unless they comply with the procedure to do so (providing ID, pre-screening, etc).

Since you just starting to rent it out I would include the down payment and any major repairs you have done.
