Thanks for being the voices of reason, everyone. I was totally baffled as to why anyone would automatically sign up for a 30+ minute commute when there are other, saner options. We looked around a bit and found plenty of 3+ bedroom rental properties for around $1500-1800/month, which doesn't seem particularly expensive to me.
And thanks for the heads up about the tax nightmares. We were already sort of aware of the hassles, but yeah, we're going to be in for a wild ride the next few years.
Unfortunately, the job will be nowhere near a SEPTA station, though it looks like there's company-provided shuttle from Norristown.
