I m not saying 'starting price' is wrong, but if, as I suspect the plot was up for an Auction Sale, then I suggest that, in this case, 'bid' is the preferred terminology for the procedure. To start the Auction, the Auctioneer offers a starting bid (price). If that 'bid' is accepted by a punter, then that becomes the 'initial bid price', of the item on Auction and the Auction either stops there, if there is no more bids, or it carries on until bids stop. The 'final bid' brings the hammer(gavel) down, and that bidder is the winner.
