A prominent property broker is selling a property neighboring mine, and advertising that it has two driveways. Problem in, one of the driveways is mine. I have viewed it in the public records, and the whole driveway is on my property. Every time they are showing the house or working inside it and I am away, my driveway is full of cars. The property owner has even left hand written notes on my vehicles threatening to tow them if I don't park where he pleases in my driveway, and threatening to revoke the agreement with my landlord that I can park on "his" property. No such agreement exists; 10 years ago, a previous owner of my home had a verbal agreement to allow the last owner of that home to park in it. My landlord will not take action until that property is sold. What can I do?
