My tenants just called to tell me they will be moving out at the end of September. They have been living in the house for 15 and 1/2 months. They originally signed a 12 month lease. I did not have them sign a new lease when the original one expired on May 31st 2009. In that lease, I have that they must provide a 45 day notice to terminate lease. With 9 days notice, I will not be able to rent the place by October 1st to cover the next months rent.. I thought that is was a common Law? knowledge that you should provide 30 days notice prior to moving out of any place. I would like to keep a portion of the deposit at least to cover the cost of lost income until I can get it re-rented. Is this legal?
