If they push back, give them the full 90-day notice.

My question is, do I need to send a non-renewal notice as well? 

Until the lease ends and then the legal notice time in your market has passed.

I have sent multiple 14-day possible eviction notices and still nothing.

I’ve never opened a mail drop store, so I can’t speak to that, but I’ve noticed that a lot of investors are turning to pad splits as an alternative strategy.

Quote from @Nicole Laba: I work with investors in Chicago who are actively buying off-market properties, and Ive noticed that everyone has a different approach when it comes to sourcing deals.

It's a 14-day notice in Alberta.

Is that 120 days from the notice of sale?

Are there common red flags you’ve noticed?

Despite this, I have tried to be patient and haven't initiated any eviction proceedings, even though Hawaii Tenant Law allows me to issue a "notice to pay rent" after just 5 days of delinquency.I've heard that if you're having issues with a military tenant, you can contact their commanding officer to help resolve the problem.
