I had to leave my apt during the second year of my lease. I called my landlady on the 8th of the month and told her I was leaving. She said that wouldn't be a problem as long as I kept paying the rent until it was rented again. I agreed to do this. On the 20th of the same month she called and told me that it was rented as of the 1st of the month. She also said that she had decided to keep half of the security. There is no damage to the property and she is not out any rent money. Can she do this?
