Coin-Operated Washer & Dryer?

[Stetson T. Stallworth]

Hello #BPFamily!

I'm considering buying a coin-operated washer & dryer for our newly acquired fourplex. I have no experience with this, so my question for all you more experienced landlords is this...

1) We only have four units... Will it be worth it? The goal is to offset our water bill each month.

2) Are used machines usually reputable? Or should we just bite the bullet and buy new?

3) Are there any brands that you all have had good/bad experiences with?

Thank you all in advance! Y'all are awesome!
