Short followup...
Called - left message.
Got called back this morning - middle man... he screwed up my name and also kept referring to my FIL as my "uncle" (OK - whatever).
Said "I don't know what transpired on the phone conversation you had with her [the sister]".
I gave him the short version - told him that I was comfortable with my valuation... He jumped in (with attitude) and said "really - because I asked around too - and it's worth more - where did you get your information?"
I replied "Three independent dealers, multiple web sites and the Iron Orange Book from 2006 - all agreeing within $500-$1000 of my offer."
His response (with heavy attitude and inflection) : "Ohh (pause) well (pause then voice turns aggressive) we have someone who's interested and has offered more - so are you gonna offer more?"
My response - "NO, no I'm fine with my offer in cash - can pay you today - no financing issues like your last buyer. I wish you the best of luck - with your other offer - which I would have taken as soon as it was made if I were you." (maybe you can tell from my response - I was past having any interest in dancing anymore)
"Yeah - well I think it's worth more (click)"... so apparently my offer was so offensive he felt compelled to hang up on me.
Given that my FIL told me this clown wanted to talk to me this weekend - I didn't get around to calling him until Monday night - and he didn't call me back until this morning... I gotta really believe the other phantom offer is a piss poor attempt at pulling the used car salesman tactic. Ohh well - there are lots of other tractors in the world...
