Tri-plex laundry room

[Mark Douglas Hukill Jr.]

I am a new owner of a 3-plex and I am trying to figure out what to do with the basement. There are two points of entry into the basement: one is a door that leads outside, and the other is through a door that leads to the front unit. Currently only the front unit tenant accessing the basement. The basement has the water heater, furnace, and a washing machine (I will be installing a dryer).

I am debating on turning the basement into a community laundry room. I see that there could be some issues with it, but it will allow me to raise the rent a bit for each unit. I believe I will make see more income if I raise the rent on all 3 units instead of just the front one for having access. 

Does anyone have any experience or advice with community laundry rooms?
