Cash flow for a commercial building:
Occupancy times rental rate, minus expences ... right?
Of course, capital asset value is different.
So adding charging spots will cost more, but might bring in more tenants.
For a one-tenant building, built by or for the tenant, the charge spots are an additional expence, but might attract better employees, and even customers.
