A guide price is the seller or estate agent’s indication of what a property may sell for, rather than a guaranteed price or formal valuation. The final price is the amount agreed after offers and negotiation, and it may be above or below the guide price depending on demand, the property’s condition and the buyer’s circumstances. Even when a bid is accepted and the property is marked sale agreed, the sale is generally not binding until the contracts are signed and exchanged. Check the process with your solicitor and review comparable properties before deciding what to offer.
