It does this to the point that I get bothered/annoyed/frustrated with people when they sleep in and waste away their morning.

Our unit turns typically do not exceed two weeks at the very most (major work).You definitely have a right to be frustrated and annoyed!

Some sellers are super annoying about even considering an offer without a preapproval letter, and banks can take forever to give them to you.

That's what's annoying my mother in law.Another point someone raised is if you need a PM license.

There are exceptions of course but in general if some one is annoying you you need to fix the issue.

Oh the annoying part was handwriting the actual envelopes and licking stamps.

I know collecting rent in cash is annoying because my tenants paid me in cash before but now they pay me rent every month via Tellus.

This is both annoying and unsurprising in our newly tenant rights org dominated state legislature. 

The only downside is the annual inspection of the unit which is annoying.

I find it to be annoying when people try to act like they are the world's smartest investors when comparing theses that seem trivial to me i.e. a little more or less interest earned by different products when most people don't bother to analyze investments that have a significant impact on their finances and people are 'penny-wise and pound-foolish'.I will back up any insurance salesman and they are well-worth their commissions considering the knowledge they have to know.
