Our electricity is already separate and we designed our ADU to be all electric so no gas. 

Oil and Gas offerings are what I have heard a lot of people move too.What I always caution people who buy vehicles is: Are you buying it because you need a new vehicle or are you buying for a tax deduction.

Mark down all the multis you see by looking for two or more doors in front or multiple air handlers outside or gas meters.

The one we walked away from needed a roof (and more) and was leaking inside the property - bank could not have cared less. 

As for the origination of the leak, it is your responsibility to provide proof that the leak originated in my unit.

Are there separate gas, electric and water meters for each apartment?

The gas line to the stove looks awful and dangerous to someone who has kids.

Are all 4 units metered for gas and electric separately or on master meter? 

Here’s what I do with my rentals:I either have tenants split the utility bills or include a clause in the lease that states if the gas or water bill exceeds a specific amount ($X), the tenant will be responsible for the overage, provided there are no leaks or other infrastructure issues contributing to the high usage.To determine this $X amount:Water: I take the highest water bill I’ve had over the past year (excluding periods where leaks occurred) and add about $15 to account for small fluctuations or potential increases.Gas: For gas, I calculate the median bill during the winter (when usage is highest) and the median bill in the summer (when usage is typically lowest).
