I have been in the buying land position. Last lot of land was sealed bids, which I hate. At least auction you know what you are up against. we did not even have a guide price.. To help. Only reason we git it, was we bid at both lots, whereas horsey people only bud at one paddock
What you bid at would attract a lot of interest......all after the same thing. which does not cone up very often. Some one will now get planning for a house on that land, making its value even higher.
Paddock near us, 2.5 acres went for £14,000 per acre.
I have a 1.5 acre paddock and if I get outline planning on it, a builder will happily have a static on it, and give me £,150,00.
Keep looking, and good luck. We got very down, as we missed out numerous times when buying extra land and its not easy.
