Do the math to find out what their usage was and bill them based on that.

I had a SEC 179 write off in 2023 that brought my income in 2023 way down (I'm a YouTuber and Blogger - I film a lot so I got a truck over 6K lbs and wrote it off after documenting 65% business usage via my mileage logs.

So you can actually split this proportionately to the usage of your home.

  * Water- if you are not billing it back to the residents most utilities have a base rate then a usage charge over the base usage allowance. 

So, typically a landlord will want to pay those directly and either bake the cost into the rent or bill a tenant back if the bill is based on usage like a water bill.

Talk to the tenants and ask if there have been any problems with the gas as the usage has increased compared to last year.Without separate meters, have each unit pay 50% of the bill assuming the units are similar size. 

Also, you could streamline the agreement, layout usage areas for each person etc.

One of the ways we have been doing that in our multifamily properties is by adding sub-meters to the water lines of each apartment and passing the water usage costs along to the residents.

However, any of us agents worth our salt will vet that for our clients when buying so it won't be much of a problem for you.
