Hi, As a self managing landlord if I send termination notice(or inspection notice) by email, will it be considered legal? Is it possible to put a clause in rental agreement to have them accept notices via email instead of post? below is excerpt from Tenant's Union of NSW website: "You must properly send or deliver the notice to the landlord/agent: in person, by post, by fax, or by hand in an addressed envelope to a mailbox at their home or business address. Keep a copy of the notice and record how and when you sent or delivered it." Another question: if I hand deliver envelop to their home (rental property) and put it in mail box, what proof do I have that I really did deliver the letter. Can I knock their door and have them sign the receipt? What if they are gone holiday or refuse to open door or sign receipt? I can registered post the letter but have to consider the postal delay etc. Please advise.
