I would not personally ever invest in a property that did not have all separate utilities in light of the potential misuse/abuse  and non payment issues that will definatly arise.

Has anyone heard of bank stacking (I may be misusing the term)?  

Another tenant mis used the dryer last time and I had my handyman fix it on the same day.

The reason I ask is that in the last 10 years the term investing in real estate, and real estate investor has commonly been misused for people who are in a real estate BUSINESS, not real estate INVESTING.Examples of a real estate business are wholesaling, fix and flip, hard money lending, etc.

It’s simply misusing/ mistreating the property.

You could state that pumpout for issues/misuse or above a certain frequency is on them. 

But above comment is probably right about tragedy of the commons effect on "everyone's laundry area" which can be a cleaning and utility cost issue and even vagrant or misuse issues..

Response rate is often misused as blanket term, really meaningless as far as non-vanity analytics is concerned, here is why; - Response rate is only relevant when derived from a specific segment or target.

@David HodgeWhile the CAP appears simple and consistent on the surface, it is one of the most misused and deceptive ratios in investing.  

It is no different than any other utility - are you liable if your tenants misuse the water or electricity (i.e. grow op, unlicensed home brewer, etc)?
