I am buying a new house and there is a Japanese Maple in the backyard. The current owner told me that her "tree guy" yelled at them for the way the were pruning it years ago and has been taking care of it ever since. He told them that it is worth $10,000. I am not sure of the exact type, but it is about 6-7 ft high. My question is, is that even possible for any type of japanese maple to be worth that much and how would I go about trying to sell it?
