As a Realtor® who also Invests, I appreciate where you are coming from... and you will!  

While I am no attorney, I am a Realtor® and Licensed Broker in the State of Arizona who does wholesale, and helps people across the country with the sales skills to do the same.  

One of my tenants called and said  that their washing machine was not working, was leaking water, and that there was a burning smell.

You are merely buying an investment machine that can only be expected to throw off a limited amount of cash that you will (hopefully) collect and you are now the one responsible to do that.Use and escrow company and get title insurance.

Apartment dwellers are less likely to own their own machines though.

If there is a possibility that they want to install their own washer and take it with them when they go that would work for me, less wear and tear on my appliances but you have to have the storage space to sideline your machine.
