Who Prorates Rent Using a Bankers Month

[MARK F.]

There's conflicting information about the "Correct" way to prorate rent.

At least some professional property managers state the correct way to prorate rent is based on a 30 day bankers month, regardless of how many actual days there are in a month.

Doing the math, this arrangement generally works to the favor of the property owner/landlord, albeit slightly.

I have also been told that certain states legally require rents to be prorated based on a bankers month.

I use 30 day months for the purpose of proration at the direction of my CPA.
