Keep or remove washer/dryer in unit

[John Warren]

Hello everyone!

When my wife and I closed on our new fourplex we knew there were several issues we had to take care of with the township. One of them is that the plumbing for the in unit washers may not be vented properly. I am getting this checked out by a plumber friend this week, but I still am debating pulling the washers out and replacing them with a coin-op to offset the water bill (paid by me). I also could just use this as an excuse and remove them altogether and not have laundry in the building. 

The building is located in a solid C+ working class area where many comparable units don't have laundry in unit. The rents are all extremely low, but I may be able to raise them to top of market if I do keep the laundry. Current rents range from 550-695, and the market appears to be between 750-800/ What do you all think?Should I keep them in unit, replace with one coin-op, or remove them completely?
