I have a rental property with a 1 yr lease. The tenants paid 1st monthes rent and a security deposit (same amnt as rent). The lease states that the security deposit will be held until 30 days after move out, then remaining monies will be returned. The current tenants gave notice two months ago (via e-mail). They asked if their secuirty deposit could be used as last months rent. At the time I had no idea of what state the house was in. After agreeing, only by e-mail, I had an inspector look at the house. ( I am out of state.) There were several issues where the tenants had breached the contract and they were very difficult when I brought these up.I do need the security deposit to offset costs that I will incur, therefore need them to pay last monthes rent. My question is: Did the e-mail where I agreed to let them use their security deposit for last months rent override the terms of the signed lease agreement, or does the lease take precedance. Is the fact that I never recieved anything in writing from them other than e-mails matter regarding lease termination have any impact on this? Any advice is much appreciated.
