Best PM software for new investor, 1 property?

[Matt Jones]

Closing on my first investment property shortly, and will be doing long term rental.  Looking for the best software option to manage tenant screening, invoicing, accepting payments, etc.  

Not a huge a mount of cash flow and since only 1 property, want to minimize the fees as much as possible but also setup a process that can grow with me.  

So many options out there, any applications that clearly fit what I am looking for and if so, why?
