Coin Operated Washer.... New vs Refurbished

[Chris Renzi]

Hi BP, I have a duplex that I inherited two sets of washer and dryers. The set that is hooked up to my unit (house hacking), is old and broken. I plan to get a coin operated machine as I'll be moving out next year and renting from here. Few questions: 

1. Speed Queen seems to be the best coin operated washer for this type of rental? Any other's I should consider?

2. What are folks experience with used/refurbished Speed Queen machines? 

3. Have folks purchased refurbished machines from Laundry Solutions: https://www.123laundryshop.com...? If so, what's been the experience? 

4. I'm debating on switching out my current tenant's washing machine with the coin operated one and hooking their machine to my electrical box.. However, I'm hesitant as I don't want to create potential unnecessary friction that may lead to headaches. Note, there's nothing in the lease regarding laundry. Thoughts? 

Appreciate the insights!
