Coin-op Laundry or in-unit laundry??

[Calvin Thomas]

We took over a 15 unit building and have been renovating it ever since.  It's not in the greatest area, however, the people who visit the apts within the building state they like the upgrades that we've done.  Issues that we've been told by perspective tenants are no parking (can't do anything about that) and no laundry in the units or a general laundry room within the building.  I was thinking about taking one of the vacant units and turning it into a coin-up laundry room.  It would sacrifice an apt, but if that is a big issue, we need to find a solution here.  Or, would it be better to just add a washer and dryer combo unit to each apt?  We could put it in the basement, but the basement is a mess.  The stairs need to be reenforced, floor needs to be set, needs a ceiling, etc.  Trying to find the best and most economical way to fix this problem. 

Any advice would be great.  Thank you.
