Ken Latchers - I have a 4 unit in PA that has separate water meters. My advice is to bite the bullet and pay for the submetering. I've seen [b]individual bills over 100/month - when someone else is paying the bill (you), these tenants will abuse it to no end. They keep sink water running so their beloved cat always has fresh water, etc. Funny though, as soon as they are paying the bill, you'll see it drop by at least half. Guess felix goes back to toilet water...
1k per meter install sounds extremely high - is it possible to do most of the 'grunt work' yourself? Running new feeds, etc - then just having the water co. install the actual meters. I admit, I don't know what it SHOULD cost to do this - but even at 5k, I'd do it in a heartbeat. It will pay back rather quickly - and will certainly alleviate stress immediately.
As for the laundry - if neighboring comps in the area do not have laundry AND are all paying their own water, at roughly the same rent: that kind of answers your question. Take it out. You may have some immediate turnover, but the upside is you now get a chance to put some better tenants in place. Also, if you were to keep laundry - wouldn't that be another sepate meter (you pay)?
