I'm not interested in becoming a "slumlord" so I believe that a mobile home or two wouldn't be optimal for me. 

To achieve that, tenant is expected to do due diligence and exhaust all available resources, e.g. internet research for DIYs videos and articles, to try to diagnose and fix the problem.b.

That is not so easy as they make it sound on late night tv.Most people will tell you if your primary goal is simply being wealthy, you are much less likely to achieve it.

Defining your goal allows you to concentrate your education on what will help you achieve that goal.

That is when investments can get dangerous.I don't have exact statistics because have been out of MF for awhile but over decades of time annual 1 to 2% rent growth, 50 to 60% opex, and 10% vacancy is more reasonable underwriting. 35% opex can be usually achievable when the property is built brand new for years 1 to 5 or an older property where everything was replaced.

@John Woodrich I love the optimism!

Has anyone been able to achieve this? 

Additional concessions achieved following due diligence and inspections.

In this case, it seems like buying two Vegas homes with the proceeds from the Hawaii sale is the most optimal option.

Of course the riskier the investments the greater the return, which may allow you to achieve your financial goals much quicker.
