property management fees & software advice

[Kevin Olson]

hi BP, 

Advice question for property management and what you have found as easy to use, fairly cost effective management software. 

I know property to property it varies, and I'm sure state to state, but I am looking at managing a couple small multis in Mass and growing from there. I've seen fees associated from 5-10% of gross income plus leasing fees etc. Would 7% be a fair number for 2-5 unit properties?

Also any current property management software recommendations would be greatly appreciated. 

Thanks!
