VerticalRent, Buildium- Anybody using?

[Dan Kelley]

I've submitted an offer on a 6-plex and currently own a duplex. If I do get the 6-plex, I'd really like to start off on the right foot and have a solid system in place to handle the larger tenant pool. 

Are any of you using VerticalRent or Buildium or similar? I'm on vertical rent now and I have a trial of Buildium, but there are a few things I'm not certain of. 

1. Without actually setting up the online rent payment collection (which involves a setup fee a linking it to my account) I can't tell if the tenants are able to apply partial payments to the rent. Obviously, I don't want any partial payments to be applied. Do you guys know how they handle this?

2. Are tenants able to pay their rent before their due date? I'm sure it's a rarity, but my thought is if I have a tenant who is, let's say, going on vacation for a week and wants to pay their rent before they leave, will either of the programs allow this? Or do they only allow rent to be collected on the 1st?

I'm sure this has been covered but I did a search for VerticalRent on the site and couldn't find much. Thanks.
