We still offer our student tenants the convenience of having a single payee for rent and utilities, but use a separate utilities agreement whereby the tenants prepay an amount into a Utilities Budget each month and are given copies of all utility bills so they can monitor their consumption.  

If the panel has the breakers labeled, you might be able to turn it off and curb the power consumption right away.

The term “transient accommodation uses” includes but is not limited to hotels, motels, recreationalvehicle parks, tourist lodging facilities, resort condominiums, resort dwellings, vacation resorts, and dwelling units occupied or available foroccupancy on an interval ownership or “time share” basis, when any of the above are made available for occupancy more than three times in anyconsecutive 365‐day period and the right of occupancy is for a term less than monthly.The term “transient accommodation uses” does not include any of the following uses if such use otherwise complies with the applicablerequirements of the City and is licensed by the State of Florida, if such licensing is required by law: bed and breakfast homes, community residentialhomes, nursing homes, rehabilitation facilities for persons with drug, alcohol, or physical impairments, respite care facilities for persons withterminal illnesses and their families, short‐term/emergency housing or long term housing where allowed by this chapter, and child foster homes.The term “transient accommodation uses” does not include a guest house dwelling, when one or both of the sleeping rooms are located as apermitted accessory use within and incidental to the primary residential structure and the primary residential structure is owned by a naturalperson and occupied by the owner.

This device monitors usage, so it would (should) recognize the large spike in consumption that a main break would create. 

More people cooking/sharing a kitchen, more showers being taken affecting hot water consumption, more persons to occupy one of the couches or tvs, more personalities to adapt with and keep consideration for, etc., plus the utilities you mentioned- water, Wi-Fi, shared amenities such as paper towels and soap etc.I’m not trying to be combative, as your point makes sense.

How about someone under 21 having a credit card or drinking alcohol?

Since Fannie Mae guidelines are published for public consumption, there's no secrets with this stuff.

If there are a lot of neglected yards, the area is full of either renters or alcoholics.

Not to scare you, but I did share a post here of a tenant that literally hacked his landlord when she went to address something with him after she had already indicated eviction proceedings.The landlord ended up in ICU and I did not follow the story enough to know if she lived.The article indicated that even if she lived, she would be left with major brain damage.Once eviction papers are served or termination of tenancy communicated, I would be very careful about going around said tenant as emotions are high and worse where drugs/alcohol is involved.I would for the most part keep away and handle this per the advise of your attorney.Did an eviction once of inherited tenants that a year and a half later, continued to challenge my policies and damage the unit, and it was tough, but seems that eviction (at least once especially with inherited tenants) is just the rite of passage most landlords have to go through.Not saying you will, but as @Marcia Maynard says, please be safe.
