We have sold our house via a high st estate agent. We are now at the point where we want to put an offer in on a property with a rival agent. Our estate agent has offered to do the bidding for us. We didn't even realise they offered this service. I can't see the hartm if the property we want to buy isn't with them. Anyone else done this? What are the advantages/ Any hints and tips (we probably won't let them know our top figure if we do take them up on the offer).
