The last place she gave me was her grandparents home.

We have considered renting washers and dryers to our tenants when the owner doesn’t want to provide them.

For a renter you describe including a washer/dryer is probably more appealing to them than having a brand new modern aesthetic as in many markets those are not typically included.

I was here during the 2011 tornado outbreak, which was pure chaos (google "2011 tornado outbreak" if you're curious). 

It recircs the water from the drying back to the washer or a front basin.

OK, with washer/dryer I am maybe closer to $800. 

We also had two washers/dryers so this helped with volume.

Before I answer this question, I think it is important to make sure you know what want and can afford.For me, I wanted a property that was pretty much turn key and required minimal updates (painting or adding washer-dryer) as a buy and hold investment.

For instance, today, walking the project I noticed that we didn't address the washer values. 

I am seeking recommendations for companies or resellers that specialize in App/Card-based Washer/Dryers.
