I could have washed out like most teenagers..

Preamble - identifies Lessor (property) and Lessee (laundry vendor) - includes date of execution & lessor description and address, A typical lease will include number of apt. units and identifies number of units with connections (if applicable) - keep in mind that if you have in-unit connections for washes and dryers you present competition for the laundry room resulting in possibly reduced usage and reduced revenue.

It took a year of washing to get the color right, and remove the stench!

You can rent it to yourself, but then you would also have to declare that income, so it becomes a wash and not a write-off?  

It's like washing your hands and wiping them off with a dirty towel.

Before buying any long-term, expensive assets such as vehicles or washing machines, we always read reviews, talk to friends and family, and research options before making the purchase decision.

As for the smell, remove floor coverings such as carpets, remaining drapery, wash walls, and paint.

I’m especially thinking of hand soap, body wash, coffee, and then towels and sheets as needed.Have you considered how you plan to manage pricing and messaging?

For example i have a property where PITI is 1607 but rents are 2350, and it shows up as a wash on my DTI. 

Like washing machine overloads or garage door misuse.And if you paid $500 for all those repairs count yourself lucky.
