Greek life opens you up to more opportunities than you would get otherwise. With that in mind, you pretty much get out of it what you put into it. If you're going to join IFC greeks, which is what it looks like you're doing, then prepare to spend $300-$500 AT LEAST in dues per term.
If you live in house, sometimes it's a lot more.
But if mommy/daddy pay for all of your expenses, you're good to go.
I am Omega Delta Phi at Oregon State, we were only founded in 1987 nationally and locally in 1999. We're in UGC (United Greek Council), which is a different umbrella organization than IFC (Inter-Fraternal Council). My dues are minimal, as in less than $300 a YEAR for both local, national, and UGC dues.
With that being said, I've gotten more out of this brotherhood than I would have in any other facet of life. And this is just my opinion, but IFC fraternities aren't all that they're cracked up to be for everyone.
