In that letter, I do not make ANY accusations, I enumerate my observations, For example: on Mar 10 between 1-1:20 we saw 8 cars pull up and idle near your apartment, occupants exited the cars and spent 2-4 minutes each inside your apartment, then exited your apartment and drove off.

He might be smoking it, but from what we have observed, it is her.This morning I woke up and went to do my morning potty stuff and my bathroom was reeking of the smell of this stuff.

If you send their support an email explaining why you'd like to do bi-weekly payments, I feel like that helps move it up their list of possible features to provide.Outside of landlording, I have observed that some people have trouble wrapping their head around getting paid 26 times a year. 

My observation is this is a very special niche property, and therefore more difficult to rent.  

I'll believe it when I see it.In short, and this is not legal advice, just an observation from experience.

Don't ask me how I know but the best way to show the tenant what the problem is, is to remove the toilet, take it out into the yard, and proceed to bust it up with a sledge hammer while they observe (wearing safety glasses of course). 

When touring the property, use your scoping skills to observe how well the current owner has maintained the property and how well the tenants take care of their units.

Observe how the person interacts with their dog.

That's neither right nor wrong, just an observation that not everyone has the same debt structure as you. 

Make it clear, section X of the lease states...I have observed XX on this date.
