Unfortunately, the timing of the move wasn't perfect. Right now I'm paying rent for my current apartment and the apartment in New Haven. It's only for a few months, but it definitely sucks to pay $600 a month (each) for an empty place. It's the price to pay for the great opportunity, I suppose.
Our landlords in New Haven were pretty cool about us leaving. Why wouldn't they be? We're still paying rent. They did put the place on the market as soon as we told them back in late February, but haven't had much luck. One of the more interesting tid bits, explained to me by one of the landlords, is that the apartment is a little too far away from the Yale shuttle bus route to attract many Yale students (not to say Yale students would be searching for a new apartment in March anyway).
The point he was really trying to make is that he can't charge as much rent as landlords with similar, if not inferior in quality, apartments located on the Yale shuttle route. Even being one block away from the end of the route can be a problem. The value placed upon convenience and location by Yale students is higher than the value they place on the living standards within their physical domicile. Good for those lucky landlords, bad for my landlord (and therefore me, the absentee tenant).
On the flip side, I now live just far enough away from Tufts University that it's inconvenient for students who wish to live within walking distance of campus. My rent is therefore fairly reasonable for the location. Tufts doesn't have the same sort of shuttle service that Yale has, so I'd imagine the drop off in rent pricing isn't as drastic here in Medford. I have no data to back that up. Just a guess.
