Thanks for the Rent Manager shout out everyone! @keithme, there are quite a few of us in the software realm that offer a wide variety of features - it really just depends on what you are looking to use. I would determine if you’d like to have all of the bells and whistles from the get-go or just a few features to start utilizing with your first park. Most importantly - go with software that can change and evolve around your business model as your business grows, not the other way around. And that goes for any software, not just property management.
To answer some of the feedback on this post, we do offer a standalone version where you purchase the software outright instead of having a monthly fee. The online version does offer many more features and the safety of our data center for backups. As for training, we offer Rent Manager University (free version available), which holds a vast library of training videos, free weekly training webinars, and a help file built into the software to walk you through each feature.
Good luck with your first park!
