So what happens if I have invested in a crowd funding platform and then the worst nightmare happens, they go under and its time to liquidate assets (or do they even liquidate the assets): how do I get paid back and to what amount and how does that whole process work?

I have a lot of personal liquid funds I'm already using but was looking to see if there was a way to use this additional capital towards the business.

Unsecured creditors would also have priority and would be settled from either sales proceeds or other estate cash from other sources.If forced liquidation sale occurs first (that's all a foreclosure is) then that secured creditor's debts get satisfied first. 

(Example: if I find that I'm in the beginnings of learning a hard lesson) I want to be as liquid as possible.

-Liquidity: if they lost their income, do they have reserves they could pay their rent with?

I mean I look at my own personal PG's with my commercial bank I have close to 10 million out with them at any time if it all went bad at once.. do you think they are going to collect.. if I had 10 million liquid I would just build my projects with CASH and take Zero risk with borrowing money.

A good question to ask yourself is if the investment held for 10 years without any possibility for liquidity, would you still make the investment?  

You will need to confirm work complete and be careful on billing ahead.You can have liquidated damages (penalties as you call them).  

Don't need real bead board, use the 4X8 sheets of the faux stuff and liquid nail it to the tile. 

Does the contract say Specific Performance or Liquidated Damages?
