I think this is an old post but I'll put in my two cents since I'll be house hunting out there soon and have the same dilemna.
I was able to defer my admission to Rutgers-C one year in order to get my life back together and buy a house. I figured NJ for the great tuition break...then I saw the tax rates in NJ. They are insane!
Anyway, if you're looking to buy, Pennsylvania would be a better option. We're still flip-flopping with the idea b/c of the in-state tuition. Currently, the tax rates would be about 6-9K for a 250k home (per year). The tuition diff is abt. 7k out of state. However, from living in California and knowing that Jersey is just as fiscally messed up, I know that the first thing they raise is the tuition for the out-of-staters. Decisions, decisions.
