It may not make sense to purchase a coin operated machine as they are soo much pricier than regular machines.

I rent the adjacent townhome on Airbnb, and only allow 2 vehicles there.All the huge vehicles on the street make it difficult to maneuver, and the optics look trashy on an otherwise upscale(ish) street.... ie one truck has had an old washing machine in it for 5 months. 

Depending on the setup I might shut off water to say a washing machine in the basement. 

For those that are interested, it took me almost a month to book a contractor (that I'd never used before) and the bid came in at $3400 for:interior paint (~1000 sq ft)patch drywall holesreplace outlet coverswashing machine and dryer hookup So, that's what $3400 will get you here in San Diego.

The ozone machine on Amazon for $80 is what I used in my very heavily smoked in house before we moved in. 

@Mike A.I too have coin operated machines and it is a bit of a hassle for tenants and me with all those coins!

I'm looking to take some of the profit and begin building the BRRRR machine out of state, but I also want to save a portion for a rainy day.

You can charge higher rent (~$50/mth); the tenant pays some - or perhaps all - the operating costs (electricity/gas, water, DHW); and you can use residential machines (A high-efficienty front-load laundry can be found for $1000.00 or less).   

Those machines are much more expensive than residential ones.
