Oh BTW make sure your new electrical panel has extra spaces for the future, is equipped with breakers that trip on both thermal and magnetic overloads and is permitted. 

Just vending machines? 

Traffic flow-does the traffic flow and the businesses right near the wash support these incomes and any potential growth.State of the equipment-is the equipment newer or older, is it well maintained?

Expected cash flow should be your best projection of the cash flow and should have a vacancy estimate, PM costs, Cap expense estimate, maintenance estimate, any utility costs, and misc fees that often are calculated over the sum of RE investments such as LLC, umbrella coverage, office expenses (space/help/equipment), car mileage, etc. 

No storage leads to a lot of outdoor clutter i.e. bikes, BBQs, Lawn maintenance equipment etc.

What is everyones general opinion on equipping or not equipping their rentals with a washer and dryer.I'm sure some landlords are all for it, some the complete opposite.

It's tough to get new equipment.
