This sounds like a fictitious example.The cities with the largest long term rent increases in absolute and relative terms (i.e., $ per year and % per year) are those with the strongest rent board regulations.  

My question is, shall I also pursue my real estate licence?

So no RE licence needed?

I have his driver’s licence so that’s a start if it’s him.For the deal i need to find the solution so I could at least recup my loss.

Its 120hr I think to later sit for your broker's licence...Anyway, yeah it can be a lot if you aren't familiar with real estate. 

Besides, you have just as much at stake, if not more, than I do.As for your other question, while I don't know AZ specifically, but plan for something like $2k-$3k in annual costs just to maintain your licence is what I've figured is a decent ballpark for around the country...

I could be wrong but it seems to me I have heard either Brandon, Josh or maybe it was a guest say that you had to have your real estate license to use the MLS or maybe they just meant to take full advantage of it. Can...

You are looking for a dream contractor :D))Licenced , fairly priced, will make your project priority etc...I think pandemic did not slow their business, most contractors I know continue working. 

A few weeks ago I got some good advice here about how to get my real estate licence.
