Yes you can put in a higher offer, no law against that. It might work or it might not. Nothing is set in stone until exchange of contracts.

That totally svcks, however if you didn't get it writing it's not legally binding. You could try putting in another bid, but I wouldn't expect a favorable reply. Sorry.
You were not quick enough. Start looking for another property and this time make your mind up faster.
I'm in Edinburgh, Scotland and had my heart set on a country cottage for a long time and was planning on putting an offer in for a house at the fixed price it was asking for.
I received a phone call to say that the seller already accepted an offer this morning at the asking price.
This was just a few hours ago and nothing has been signed. I'm devastated and want to put in an offer above the asking price, but is this allowed due to the fact that there has been verbal acceptance? Nothing has been signed as of yet.
