I have 4 months left on my prepaid lease. Landlord wants to place "For Sale" sign in my front yard. The listing is online, in local papers and ad magazines, and in mailings. I have already had curious people "wander" onto the property. Must I allow the landlord/real estate agent to place sign on property? To clarify, am I REQUIRED by LAW to allow the signage? This is not addressed in lease.
