How to add contingencies in offer?

[Travis Andres]

Just about to start out with our first investment and may have found a property to BRRRR, but want to make sure that it's in good enough condition for what we are looking to do.

I know I’m supposed to add some sort of contingency in the offer that will enable us to adjust/back out of the deal if we see something really wrong with the property, just not sure how and what language to include. 

Any help would be greatly appreciated!
