What software is the best for large apartment rental companies?

I am part of a company with limited staff, but we operate around 450 rental units in different areas. I need a good software to handle all of these properties. I have been using tenant pro 5.0, but I feel like there are probably a lot of advances that have been made, and am looking to upgrade, either to the new tenant pro, or something better.What software is the best for large apartment rental companies?
I've only heard of property management using Yardi or Skyline.What software is the best for large apartment rental companies?
Most of the property management companies that I've worked for use Yardi which is put out by CTI. for your purposes you'll want Yardi Voyager Residential. We printed monthly cash flow statements, printed monthly tenant statements, paid bills out of it etc.



It's really a great management software.What software is the best for large apartment rental companies?
If you have a programmer on hand the could look at scripts.
