Do you really think he is going to magically give up and leave? 

(I live in Magic Valley, Idaho, which is about 130 miles east of Boise.)

Between 2004 and 2014 I owned a half dozen duplexes in Rochester NY following the model that most now refer to as "out of state" investing (odd phrase as there is nothing especially magical about a state line). 

(I've got my own opinions on the notion of an infinite supply of magical turn-key investment properties that somehow have better-than-market cap rates, but I'll keep that to myself as it is off-topic.)

Usually hard headed tenants like this (in my limited experience) somehow feel they are magically destined to stay in the place with rules that only apply to them that they dreamed up in their heads...so trying to negotiate or level with them, doesn't work.

This cult of the bidding war nonsense, the idea that your home will magically sell for way more money if you list it low. 

Most claim, once they learn how to design – or create a convincing hook – they work like magic!

Bureaucrats think that if they write things on paper and give it their blessing then it will magically fix real-world problems, but vaguely enforceable laws like this won't cure bad landlords. 

Run the numbers and read all you can on the financial side and make sure the numbers work for you...Also, keep in mind:The rents can creep up over time Your property generally appreciates over timeYour debt decreases (as the tenant pays off the mortgage)And if you get a decent property and manage it well, you can keep costs in check.So you see the slow motion magic formula at work--rents going up, property value going up and debt going down....Maybe let's get in the DeLorean and time travel--set the dial for ten years ahead Doc!

When you do those two things in real estate, magical things will start to happen.
