@Adam Boonzaayer We don't make mistakes, just happy little accidents.

There is nothing wrong with analyzing a property and be cautious about it.Better than making a 10K mistake. 

In the event you make a mistake and someone comes looking, you want to be able to stand in front of the court and list the efforts you took to locate a person who may have an interest.  

Micro answer: Learn from your mistakes fast and don't lose more money than necessary.

From what you have described, I don't think he will stop, but if you begin with that first step, you've at least left open the possibility of him realizing his mistake and correcting it without threats which are going to cause the relationship between you and the tenant to sour, make your living situation miserable, and encourage him to trash his unit or create other problems.

It was amazing how fast they went from "we don't make mistakes" to "how much is it going to take?"

Learn the terms that people use often, listen to mistakes people have made and soak up as much of this great knowledge as you can.Save your money as you start to get jobs and remember, you don't need the latest and greatest of everything just to impress your peers.

In this context, here is one mistake that I see investors make over and over again, they focus on price and don't put it in connection with square footage.

Made a mistake hiring attorney who only deals with closing and not eviction and she is not helping.?

Things you learned, mistakes you made, etc.
