I don't think they're paying closing costs, just maintenance fees, so that puts us at $134/ppt.  Closing costs are estimated at just short of $700, so I'm still pretty thrilled about the deal that we're getting.
I was also curious how much it cost the previous owners to turn around and sell it so quickly at such a low price.  I made this spreadsheet to try and estimate how the purchase panned out for them.  Turns out they spent approximately $17.53/point, which is above the current rental market price (and well above for where it was a few years ago).
