I agree with Laura, if this is a long term rental it would be hard to convince the tenants that they have cameras on the property that the owner controls even with all the stuff that you mentioned (does not turn, only for surveillance for crimes etc.). 

For Guys the main things that come to mind are: 1) Property damage2) Neighbor complaints3) NOT calling about repairs that need to be made4) Prolonged turnover times For Girls they are:1) Parental involvement/helicopter parents2) Pest control 3) Security issues (i.e. house is broken into)4) Roommate dramaBoth can be incredibly difficult to deal with for sure.

I went into the bedrooms and don't notice the sloping floors so much just by 'feel' and admittedly haven't put any measuring device like a level to it. 

He's a really smart guy when it comes to supply, demand, rent control, and overall investing

Most investors will also take into consideration risk, time invested, control over the asset, the ability to do a cash-out refinance, and other factors.

Sure- Idaho has state laws outlawing rent controls.

It’s flexible and can help you fund deals quickly.Lease Options: Similar to “rent-to-own,” you control a property with minimal upfront costs and can potentially get a cut of the appreciation if you decide to buy it later.Lines of Credit: If you already own a property with equity, a HELOC or business line of credit can give you accessible funds for down payments or renovation costs.House Hacking: This might sound basic, but if you haven’t tried it, it can be a fast track to building up rental income and experience without a ton of cash down.

I never buy condos for this exact reason, having someone else control my investment.

Yes, there are things that are out of your control, but my personal POV is the whole "I need an LLC" is a little overblown.  

You have to understand your rights and maintain control of the situation.
