Property management software and book keeping

[Dallin D. Hutchinson]

So I couldn't really find any specific forum for this.  I am looking for some good, inexpensive software, or even a spreadsheet I can use to manage my rental property incomes and expenses.  I am looking for something that could also be easily deciphered come tax time.  My accountant is giving me hell for the way I manage things right now.  And with additional properties now on the books, I am afraid he's going to shoot me if I don't find something good.  Thoughts?
