Chris and Allison Larthey lucked into a brand new townhouse three years ago in Blackwood, New Jersey, near Philadelphia. It was a perfect situation, until they both landed jobs far from Blackwood. Chris now drives an hour to work and Allison drives almost twice that. So they've begun looking for a single family home with at least three bedrooms, a nice backyard and plenty of living space where long commutes will be a thing of the past.
