Writing mail for condo fees?

[Robert McCormick]

I'm co-owner of some condos with my mother where I had to pay condo fees and the majority of the payments were made via check in which I sent out a letter through the post office to the management firm in charge of the condos. Can I write off the payments I made at the post office for my taxes? I'm looking online and so far can't find anything regarding this situation. Answers would be appreciated as I want and need to have my taxes as accurate as possible to avoid losing money. I have an appointment very soon with an accountant for both the rental properties and my W-2 taxes so I'm hoping to have everything needed to minimize errors.

If you are a co-owner and they are rental properties, then you should be able to deduct them as an expense regardless of how the payments are made.
