Funds are comitted at the start of the negociations! Search fees, mortgage advice + decision, survey, this can represent a lots of money already!(£2200 for us),,,, A first offer who has gone throuh (first step of research, survey booked etc...) should have priority of decision making and seller should inform this buyer to any intention concerning the house before to do so. If a seller decide to try to get more money than the original offer, he should contact the first buyer and propose the deal or telling him that if He cannot afford to pay more, the property will go back on the market..
The house market is making lots of people richer than happier. We are dealing with businessman instead of "normal people", \ SN
