@Dave Ramirez Curious as to your experience w/ Pipedrive. Seems pretty solid and customizable.
@Chris Price I'm working w/ an agent that uses Firepoint. I would stay away. Not as many features as some more mature systems. Small company 5-10 people so development time is a bit slow. We are having to build a lot of systems/processes around it's failings (i.e. Transaction mgmt, marketing ROI, etc.)
Propertybase looks like an interesting solution. Built on top of Salesforce so it has solid infrastructure. Customizable workflows and automation. Expansive API so if you need to develop some of your own features you can.

A new entrant that I think might be an interesting option could be ProsperWorks. It's built on top of G Suite so if you are using that it is really nice.

G Suite in general has released a new tool called App Maker that allows you to build some really powerful applications on top of it. Abstracts a lot of the programming and design work. Feel like this would be preferential over Podio if I was already using G Suite (I've never used Podio).

Just my 2 cents
