It would be foolish that any syndication would not assume worst case scenario of rents coming in and be able to cover their debt for a fairly long period.

In the worst-case scenario, I might have to deal with negative cash flow and stay in the property longer than planned, delaying my second investment until I find a good solution.

That looks like common surface mold due to lack of ventilation.

You really have a couple routes to go with the scenario.

My $10k example was admittedly unrealistic.However, by way of further background, @Dustin Heiner wrote an excellent article on this topic on his website masterpassiveincome.com titled "What to Do When A Buyer Backs Out From An Assignment Of Contract".In it he suggests a scenario where the assignee decides not to proceed, perhaps after discovering a big ticket repair item that would cost significantly more than the portion of the assignment fee held in escrow. 

Be sure to be conservative on your projections and stress test the property to see what worst case scenario would look like. 

It is very common that they will subcontract out some of the more specialized work. 

Even in the best scenario you would have spent $1,500-$2,000 to update the smoke detectors and C02 testers, cleaned the carpet, re-glaze the bathtub, update any leaks and light paint and wall repairs.  

Is this a common phenomenon?
