rare / unusual Contract Contingencies

[Ben Kappel]

As a newer agent, one thing I found difficult to find online is the various different contingencies contract can have depending on different situations. (outside of the very standard one's)

I've learned a few new one's in the forums search that have helped, but thought I would ask experienced agents if they have any more sophisticated or rare/unusual contingency wording they have used in the past.   

I look forward to making a word doc to use as a reference for my hopefully long career.
