5-day notice

[Atul Mohlajee]

What has been an acceptable way to serve a 5-day notice while the tenant is still living at the property? I understand delivering to tenant is the best way. However, if tenant does not come to the door, there have to be other methods. Has any one sent a 5-day notice via certified mail that tenant does not accept even if post office tries multiple times, and you get a notice of non acceptance of mail from the post office. Does this non acceptance notice hold in court? Also, has anyone posted the notice to the door if tenant still lives there but does not come out or is not home and has that worked. Please state your experiences with the 5-day notices which were accepted and which were not? Location or State you are in does not matter, just want to get the feel of law on this topic.
