You can try to pursue them for a money judgment, but how will you collect?

Quote from @Michael Challenger: I would connect with local people at meetups, that might give you some contacts for private money.

The great thing about living in a high cost of living area is that your salary / wages are hopefully also very high.If you are a new college grad, I would focus the next 1-3 years on increasing your salary as much as possible(gain new skills, new certifications, change employers, etc).Once you make more money, you can easily get in a position to buy a property on a more frequent basis.Best of luck!

If you make good money doing that, do it again a year or two later. 

Sub2 needs to be viewed like Hard Money.

Forget the course and put that money on a quality vacation short-term rental.  

You've only owned it six months, so you probably haven't dealt with vacancies, maintenance, or capex, but you should be setting money aside for those things.Your partnership agreement (if you have one) should address exit options.

If you paid 563k and did not make money yes thats a problem.

I like to make money on real estate not just buy it to say I own it.

As others suggested you could also lend this money out for 10-12% and make your money that way and not put yourself on risk on the asset.
