To add I recently sold the same for $10,250 but paid all closing and included a prime 2012 summer week for free.
So what value did they pay? They could estimate closing is $500 and the MF for the 2012 week was $1065, so in essence they paid me $8685.
You paid $7450 which I assume doesn't include first year MF($1065) and closing, ($500 or so). So comparing to my sale you paid $1235 less thann my buyer, but did you get a good week to use? To me it would appear you got a good deal.
