I want to start fresh with an app that will track customers, vendors, personal, colleagues, contractors, teams, etc.  

This will be my first purchase of many and I want to start off in the right track.

There are several ways to track these down.  

All of those areas are interesting to me, but I am also tracking properties of interest in Dublin and Hilliard since that's where we live and work currently. 

This reminds me of the early days of dual agency, in the 1980s when it wasn't clear which side a broker was representing.

Make sure that they have a real track record as investors and mentors.

They have a pretty decent track record actually.

Make each property its own "Class", and QuickBooks will work really well for tracking everything by property.If you're using Excel and giving each property it's own column, using "Class" will accomplish the same thing in Quickbooks.

This is a great way to get the guidance you need and put you on the right track.
