When we first rent our house in 05 we had a 1 year lease that we signed. It stated we must give 30 days notice prior to moving out. After the first year we have never signed another lease, this was three years ago. They sent us one once but we did not sign it because of yard issues that my husband wanted fixed. Since we have signed no lease does this mean we are on a month to month lease? My husband received a transfer and must be in the new state in a couple of weeks, do we still need to give 30 in order to receive the deposit back? Also if we give 30 today does that mean we just need to pay a pro-rated amount for August?
