Those asking why people are looking at properties around Bath, OP said upthread that's where she was. I presume it's not exactly there, but a quick look at houses in and around Bath around 700k shows quite a few reductions and other houses that have been on a while. Not many of those marked Sold or Under Offer went on the market after October. It's very obvious the market is not crazy there. It's worth considering too that a lot of the heat in the SW came from people moving there from other parts of the UK, and a lot of those people have now bought somewhere. The exodus from cities has slowed right down.
We have just offered on a house near us - another area which went stratospheric over the last year or two but is now also showing little movement and reductions. We offered asking on a house that had been on since August, and had only had one offer, rejected for being 'too low'. We were prepared to pay that because we adored the house, and still do, but are having some concerns about our sellers. We have started conveyancing, commissioned searches and had a full survey done. Our sellers on the other hand have done nothing. They almost refused our offer as the house was marked 'offers in excess' and, despite having already moved out and living in a rented house in a new location, they insist on finding a house for their adult children to move into before selling, and haven't done much to sort that out. They haven't sent our solicitor the sellers' information pack.
We are chain free buyers living locally in rented accommodation (we are probably similar to your prospective buyers), who have shown commitment and have offered probably over the odds, and they are going to lose us if they don't sort themselves out. They don't get how lucky they've been, although the agents clearly do, and must be really frustrated. If things don't change we'll need to start looking again, but we'll be paying less than we currently are, as prices are falling around us, and the agents know that - but the buyers seem to be living in a bit of a dream world. If they lose us, they won't get the same price for their house again - I think they have a similar attitude to OP.
