Lease or buy a commercial washer/dryer? Pros and cons?

[Trevor Levine]

I own and live in a triplex with 6-7 residents. My plumber just installed laundry plumbing and a gas line in our utility room. There will only be one stackable washer/dryer for all residents. So if something breaks, I'll need it fixed right away. On this basis, do you recommend leasing or buying? 

Leasing a Maytag laundry center from Wash.com would cost me $100/mo, but reviewers say they can take weeks to come out for repairs.

A local place called Mission Laundry Equipment can lease me a Speed Queen laundry center for $110/mo, or sell it to me for $4,299 (actually $5,450 with all taxes and fees for delivery, installation, and setting up the credit card system). They have almost no reviews.

With 6-7 residents, how often should I expect to need repairs? And do you recommend leasing or buying?
