Offer on a site

I have seen a site with FPP for 60k with a local auctioneer and wonder what kind of an offer to go in with??/

Its orginal price was 160k with this auctioneer. two other auctioneers are selling it one for 90k and another with the price down at 120k.

offer 30 k

tks offered 45k last week and was told not a hope, what should be my next move

Make a time limit on the 45k offer.
