I own two houses that are on adjacent parcels. I want to sell one house (House A), but before I do so, I want to change the property line to provide more land to House A. It seems like I should be able to do this inexpensively and without a lawyer, and I am trying to figure out the steps that I need to take. Do I have to change the property line before selling House A, or can I change the property line in the deed when I sell House A? I would greatly appreciate your help in knowing the proper steps.
