Given the dollar position, I strongly believe what we have heard a few senators murmur of let states and various gov agencies default on their bonds, that their must be a bankruptcy as the math is clear that capital is running out to service their debts.

Experienced investors aren't better at math than anyone else, and they don't have a crystal ball. 

@Matt Camilliere  Double check your math.

Just make sure you do your homework and there is no evidence of having or had a sinkhole. 

So by that math I’m in it for $270k which subtracted from my $600k potential sale then it would leave me with $330k.

While some are truly unfortunate, a lot of the time, it's because they just didn't do their homework.

I’ve done a lot of homework on these duplexes and now HOA fees are thrown out there.

Doing the math we see that the land under my little house should be approximately 12.5%-16.25% of the total purchase. 

Run the math but this seems like a high risk plan for not much gain.

Do your homework.
