I have served the 60-days notice of Non-Renewal of Lease to tenants. Now they haven't paid rent for this month, grace period ended the 5th of March. I sent the non-renewal notice by regular mail & registered mail & also sent them a copy by e-mail. They are not answering my phone calls and txt msgs. regarding of when they will pay the rent for March. What should I do? Is there another Form that I should send them? I worry that they are going to vacate the house at the end of April, without paying rent for the mos. of March and April. Pls. advice. Thanks.
