We used to pay our rent in 15-20 installments, one every day or two. The office of the apartment building we lived in was on the way to our apartment, so it wasn’t any inconvenience for us to just drop a check in their drop box when we passed by, but I like to think it was mildly irritating for them to have to deal with the book-keeping. They asked us not to on multiple occasions but their only online option had a small “convenience charge” attached, so… No, thank you. I’d be happy to use it if they paid me a “convenience fee” for not making them process 20 checks every month.
