Tenant did not pay the rent due on the 1st of the month nor did he call or explain.Tenant said he didnt have the rent owed,would pay 300.00 on the 10th of the month and asked if I would use his Security Deposit towards the balance as he will be out by the end of the month. I agreed. Tenant still hasnt paid nor called to explain. I had to leave a message stating that he didnt stick to his part of the agreement so Im not using his Security Deposit as partial rent. I told him I will be giving him a 3 day pay or vacate notice if I dont receive the rent soon.He has no mail coming to this residence as it is a Rural area and recieves his mail elsewhere.Is it mandatory for me to have to mail a copy if I hand delivered it to him? Im in WA State
