I would like to know if I can deduct the lost rent I incurred when my subletter broke the lease agreement and I had to find a new roommate on a moment's notice? It was a month to month agreement and I gave her 30 days notice on July 1st to be out by August 1st. She chose to move out that weekend. I was unable to fill her room until July 14th. She broke the lease by giving her key to the house to a friend that we had never met, never announced him nor approved his stay, and he walked in our home unaccompanied in the middle of the night. She was no where to be found or reached. I almost called the cops because I thought he was an intruder. He was made to leave and leave the key. I gave her notice the very next day. We had an oral agreement about no guests unaccompanied or unannounced, and I have texts that also have this agreement established.
