I looked into this as well since I'm getting terribly bent over on my w-2 taxes. 

You can probably beat $2000/year insurance, but the management fee should be 10%, you need to factor in turnover too and 5% is probably not enough for both maintenance and turnover and I assume you added it, but you didn't mention property taxes (which have been terrible in Jackson County lately since Frank White decided to jack them through the roof).

I own all my toys, never seriously worry about money (I suspect everyone with any money always at least pays attention to it), spend my winters in Florida and rarely work in any sense (I do some consulting and side teaching) more than 10 hours a week.

They might double the 50k or better or lose it all but can just get tax write off and then make it back in one month or less.
