As a broker owner, I encountered neighbor issues while trying to sell an investment property. Neighbors were not keeping up thier lawn and trees were growing onto the walkway to our front door. Had to cut them back weekly. Conversations with them were pointless because they were seasonal; only coming to south Florida in November. We got lucky when a storm took the trees up. They missed our roof, managing to fall on the fence and walkway. Thank goodness for Mother Nature!
