Property management/ task management application recommendations.

[Russ Marlborough]

I have recently doubled my rental units from 2 to 4 and am in negotiations for another 6 units. Im trying to be a little proactive and find out what software investors are using for basic property management tools, mostly task management. Are buildium and appfolio my best options? I just dont want to spend a ton of money for software above and beyond what I need. Maybe all I need is a to do list app.

Any Recommendations?
