As utility costs rise, commercial real estate (CRE) investors are increasingly turning to smarter, more equitable ways to manage shared expenses—especially in multi-unit properties without individual utility meters.

That was cleaned up promptly, and (2) this recent drain blockage there was water in the tub and some water seep out from the base of the toilet.I am thinking may be this is a situation that may escalate if not dealt with properly.I could use a moisture meter to test for moisture behind drywalls and baseboards.I could also do some mold tests at different parts of the house especially the bathrooms and send out to have samples tested.I could take additional steps to try to prove there there is no problem, but I have a feeling either the tenant is already made up his mind that there is a problem, or this is an opportunity to make me jump through hoops.Would like some advice on how to proceed from my end. 

A water meter and an electric meter will let you know the usage 

The inspector used a moisture meter and found exceptionally high moisture in every wall (10th floor unit) of 18-25%.

In RI, if there's only one meter, the landlord is responsible for paying for the water.

Here is a real example of replacing the electric service wire from the electric company to the meter.- $110 For 5 minute rental inspection that results in issue to replace the electric service line.- Electrician quotes $900.- Municipality permit is $75.

It has a newer roof, new meters, new appliances, new hot water heater, separately metered (I WOULD ONLY BE RESPONSIBLE FOR LAWN CARE AND SNOW REMOVAL) Property has been well kept maintained and will accept FHA financing which is my best option to buy given my credit score and DTI.  

I'm acquiring this two family property with only one gas meter.

It differs county by county, but yeah they pat their utilities…If its a multfam one water meter could get difficult, i have in my lease 3 beds pay 66% and the one beds pays 33% , but that’s adjustable…

Your case is very different because you'll need to install outside disconnects and separate meters, plus all the apartment's wiring and breakers need to be inspected and possibly updated.
