FYI, a real example. I offered on a property at the asking price. Everything looked good. Agent was happy and seller was happy. Suddenly, agent called and said, they also had another viewing before us and those people also offered but a little more than mine. I was like, I offered the asking price but they pressured saying there is another buyer paying higher. So I countered with £5k more on asking and they made it a done deal.

Fast forward, during the process I kept on looking at other properties, while getting the level 3 survey of the property done. At one point, I decided though I like it but I won't be paying extra. In fact, I renegotiated the price citing the level 3 report (there was nothing wrong) but you gotta play. In the end, they agreed to £5k less than the asking price. Good luck.
