You can always ask, and more power to you if that works out - just not likely something most would consider. 

If so what do the contractors do about powering their tools on the construction site?

Consider long term costs.Central unit(s) belong to you, are maintained by you, and you need to provide power and pay that bill.Window units, even if you provide them, at least place the operation power usage on the tenant.If you clearly note in the rental agreement that "the window units are a gift to the tenant", then maintenance is off-load too.Frequently, the long term costs have a larger impact to your PnL than the cash outlay for the equipment itself.

But also note the merits and the power of equity.

Just remember talk is cheap and get everything in writing by the correct person who has the power and authority to enter into a contract.

Hello AllI have been hiding in the shadows for some time now, faithfully watching webinars every Wednesday night, downloading podcasts to listen in car, and reading reading reading from forums to Kyosaki to John Schaub to BP Beginners Guide to REI and whatever else I can get my hands on.Huge believer in the power of passive income and the teachings of Tim Ferris.

Currently working in the automotive industry, but I've spent time in the steel and power industries as well.
