how much should I charge for washing /drying?

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. 

Soft and easy washing.

@Tishon Greene every market is a bit different but it might be a wash.

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. 

You may be able to buy Continental Girbau Econo Wash, where the units just relabeled  speedqueens.

So that's a wash, right? 

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.
