Rental software

[Mahonri Bussey]

I'm going to be renting out my first town home and was wondering what are some of the methods people are using to retrieve rent? I dont want them to send me it in the mail or drop it off at my home. I would prefer an online service if there is something that is cost effective and will automate the process and also maybe send out notices for rent and late rent.. if such a thing exists. Thank you ahead of time.
