I am appraising a duplex, the rear unit of which has a tree which has grown into the wall of the structure. This is a purchase, and the buyer plans to remove the tree and repair any damage upon closing of escrow. It seems the best way to handle this is a cost-to-cure. Any input on that? The buyer already has a contract for removal of the tree and repair of the situation. I think I've got it covered now. Thank you all for your help.
