We just put an offer in on a house, about 12% under asking. We’re in a strong position as buyers and agent came back saying there had been another offer that morning for more money but weaker buyers so they were asking both parties for best and final. 30mins later they say they have best and final off from other party. A day later after much discussion we raise our offer to 9% under asking and get a call within 10mins saying it’s been accepted. House has been on the market since late October with no offers at all - was the agent lying in order to get us to raise our offer due to competition?
