Kent, if it takes 3 additional months, would it be worth the extra $25 to you? Of course, if it sells in one week for the extra money, you'll wish you had held on to it
Good luck with the decision.
Full disclosure: I was selling a car once and I thought it was worth $14K, someone offered me $13.5 and I turned them down. Then I could not find another buyer over $13K and ended up trading it in, for less (kept holding out for more money). I regret not taking the $13.5K when I had the chance.
