Need Help Figuring out how much to pay for a good CPA

[Jason Bellant]

Hello, Purchased my first three Investment property's last year and I am currently analyzing a few CPA firms to help me setup my tax structures for my LLC's. My question is when you find a good CPA and you want to keep on your master mind team and have them work hard on your portfolio and let's say their office charges x dollars is it common practice to give them a generous tip or am I crazy for thinking about taking that approach ? I just want to make sure I'm educated in this Avenue of a REI.
