I understand your pain and frustration. I too owned property of where my neighbors OWNED, but they continually harrassed me about every little thing in the book so to speak. It did not start until after my husband of 21 years decided he wanted a divorce. He left me with 2 teenage boys, a mortgage and car payment and a yard over 1 full acre to fend for myself. The men on each side of my property planted TREES on my land to put a buffer between the homes, which was ok at first...because it saved me from having to do extra landscaping...but then they called the Sheriff about us shooting fireworks on New Years Eve, my dog barking too loud, because another neighbors cat was in the yard...or the deer, that one neighbor liked to shoot out his back door with bow and arrows.....they would tell me to TELL my dog to Shut up....It was always something. I moved out of my house in October and was still making a mortgage payment AND now rent as well for as much as my house payment....and I am a REALTOR that makes NO money unless I sell a house and close. This is what YOU need to do.....I do not know if you live inside the city limits, but I am assuming the COUNTY because you said the SHERIFF came out.
Have someone you know or you call the county zoning commission and ask them to send someone out to your house so you can show them face to face what is going on. Show them anything you have to prove the property line. It really doesn't even matter about the property line. If your neighbors are becoming a nuisance, there are laws against that. Also, if these folks are RENTERS, call the COUNTY courthouse department that handles tax notices. Tell them you need to know who owns the house at "such and such " address regarding an issue with their property. It is public information. Call this person that owns the house and nicely tell them that you have a problem and there are records of where calls have been made against you unjustly by HIS/HER tenants. If it continues, you will take matters to an attorney for violation of your rights to LIVE PEACEABLY on YOUR OWN PROPERTY. After you talk to this person on the phone, write them a letter , date it and mail it "certified mail". Then the next time this mess happens, get YOUR copy of the letter out and show it to the Sheriff's deputy to prove that you have complained and you want to file a complaint against the tenants for "Disturbing the Peace", "Zoning laws" or whatever ELSE the county may find when they come out to visit.
If NONE of that works, call the COUNTY AGAIN. Tell them you need the number to your COUNTY REPRESENTATIVE....you know, COUNTY COUNCIL BOARD.... ask for the HEAD PERSON OR CHAIRMAN.....They are voted in office by the public in my town....maybe they are where you live too. Tell them that you are on SSI, Sr. citizen and you need help. If the county zoning, the sheriff's dept, the owner of the property next door and the COUNTY COUNCIL do not give you any satisfaction, look in the phone book for any SENIOR CITIZEN ADVOCATE GROUP or NON-PROFIT ORGANIZATION that helps people on low or fixed income...AND CALL YOUR LOCAL NEWSPAPER to come and talk to you.
note: I am NOT an Attorney, I am just telling you from my OWN experience...and like I said, I am a Realtor!!!! I know the laws....but the law gets called on me unjustly....don't you think thats gotta make a person wonder????
These are just the things that my local government officials have told me to do and I did.....
Best of luck, please let me know what happens....
