Just be aware of the fact that Quicken is NOT multi-user capable. It's designed to be run on one computer and accessed by one user only. Any attempts to work around this limitation will eventually lead to damage of your Quicken data file.
If you must have shared, simultaneous multi-user access to your data, Quicken is not for you.You'd have to use an appropriate multi-user version of QuickBooks or any other multi-user capable rental management software package instead.
