Can my landlord go off our old lease if he didn’t bring us a new one to sign?

This is the second time our landlord has failed to bring us a lease in time to renew. This time we didn’t say anything because we are in the middle of purchasing a home. It is coming to about a month until our closing date so we thought it would be a good time to let our landlord know we are moving. He said that he would be keeping our security deposit because we are breaking the lease. He further said that he could essentially take us to court and get the money for the rest of the lease that we are leaving early on. We said you never brought us the lease so we aren’t in one. He tried to stop our home purchase by refusing to talk to our mortgage lender until we signed a brand new full one year lease backdated to the day he forgot to bring it. We told the mortgage lender who advised us not to sign it. We told him we would rather sign a month to month. He is saying that we are refusing to sign the lease so it automatically defers to the last lease we signed back in 2019. Is this true?
