Dp and I haven't sold a house lately but have done so a few times in the past, and last time we did (5 years ago) you signed up with an estate agent but if you were fed up with them you could switch to another, no problem, or take your house off the market. This year Dp and his siblings are trying to sell their mother's house, and his brother has signed a contract agreeing that if we take the house off the market, or change agents, we have to pay all sorts of fees adding up to about £1000. (£350 for photos, more for the agent's time, more for each viewing, etc). Is this actually normal now?
