Do I put in Washer/Dryer hook ups?

[Joe Frey]

I just purchased a duplex that was built in 1899. The washer/dryer hook up is currently located in the "Cave" like basement. The upstairs tenant will be my brother and I had planned on getting him set up with a stackable washer/dryer because the upstairs unit does not have a hookup. 

So I was considering moving the washer/dryer hookup in the downstairs unit to a closet off of a hallway near the living room. 

I was thinking that it would make the property more appealing for potential renters. I will also be rolling utilities into the rent, if that makes a difference. 

What are your thoughts?
