I used to use Buildium and switched to rentvine a few years ago. I have much to say about this topic, but here are some key points.
- The support is great. It'll be mostly via email. Recently they added a feature where you can text or chat.
- You can create custom fields, which is great. You can create furnace filter size, when XYZ got installed, lockbox number, etc. You can also create custom reports.
- The accounting feature is rock solid. Please know that it's not really meant for your company expenses, such as paying BiggerPockets, seminar fees, software subscriptions, etc.
The negative is it doesn't have a mobile app (yet.) The problem with that is it'll be harder for the residents and the vendors to use the rentvine features as fewer people want to log in to a website from a smartphone.
Also, it requires a lot of clicks/scrolling/opening new pages/tabs to get to where you want.
Overall, I'm very happy I'm with rentvine, and I have no regret switching from Buildium.
