Lease Agreement Is Valid Even Without

We signed a rental agreement and then gave our deposit to the owner on 10/9; We met on 14.10. to check loose ends to approach and maintain before moving in on 15.10. It was clear that several violations of the building rules were not concluded, as well as the basic cleaning of carpets and the house. The landlord became very defensive, called her husband (who is not on the lease), and then said she wanted to terminate the lease. She asked me for the key and I told her she would get it if I received my money ($2300 she was paying). My husband told me that I was rude and that I gave him the key. She also listed the property at the same price literally right after on Zillow. Our mobile capsule is there since we delivered it for the move of the day that did not happen. (You save it).
