There’s often disparity between estate agent valuations for various reasons. Obviously people will only pay what they think a property is worth. What is the difference between lowest and highest valuations you’ve had and what area or type of property. I once considered buying a friend’s 2 bed flat, when I was looking to move, but the disparity was 50k (going back twenty years ago though). I didn’t go for it as didn’t want to either con them or overpay.
