These are things you can give in detail to the buyer:Cash flow on businesses, condition of equipment, payroll, more info on liquor license transfer, are there existing liabilities, is the seller willing to sign a non-compete clause in case they want to open another similar establishment or invest in one,  ask about current manager...staff experience, are they willing to stay. 

I was referring to starting a property mgmt company to be able to expense things such as travelling to and from properties, equipment purchases, etc etc.

Home Depot or equipment rental places rent them as well. 

I am a huge advocate for people respecting the business we are in (this means taking the time beforehand to mentally prep and equip yourself for the great real estate journey you are about to embark on).  

If the car wash is automated, you have capital equipment, service, consumables, maintenance, etc. all to deal with.

A space that has all the office equipment an people pay for a membership versus lease.

Tank less water heaters are more expensive to install and way more expensive to repair.A rental with tenant paying utilities should only have the most basic equipment supplied.

However, I don't do it on mine because its very questionable to me whether the total cost to total benefit calculus really makes it worth while for individual SFR properties that are not cookie cutter duplicates of one another, equipped very differently, bought at different times, in different locations, etc.

I was thinking along the lines of vehicle or equipment storage?  

You'll make far more in maintaining good units and giving appropriate yearly rent increases.Some multi-units own the equipment others rent.
