Tenant moved in and a month later is giving me 30 days notice to move out. I normally let people break a lease after a certain amount of time but not a month after they moved in and signed a year lease. There have been situations where people are transferred get sick, etc. my fault I said verbally 30 days notice you can break the lease never dreamed it would be one month after moving in and the excuses that she found out she has to do something else with school. I paid a realtor to rent it and now I need to pay Realtor again. Do I have the right to keep that out of her security even though it is not clearly mentioned in my lease.
