It looks like we've just bought a flat. The much-vaunted Scottish system is enormously frustrating at the early stages, as each property is essentially sold via blind auction. But now we're in a good position because we can pull out if the survey reveals anything unpleasant, or we can reduce our offer, or whatever, but the seller can't sell to anyone else, or decide they're not selling after all. Whee!

[rab] How exactly does that system work from the seller's point of view, then? Is there something that could stop you from dropping your offer down to £10, for instance?

Yes, they could simply refuse.

...and then the seller has to weigh up the relative pros and cons of accepting a lower offer than the original one, or putting the place back on the market. In our case, I don't anticipate any problems with the survey - but it's nice to know that we can pull out if the surveyor says the place is about to fall down, but they can't suddenly decide they're not selling to us after all.

Actually, I now understand we haven't quite reached that stage yet. The seller now has to agree in writing, so until we get that it could all be orrf.
