Waive Contingencies in PSA?

[Kaleb R.]

I’m taking an online class and learned that when you’re performing your due diligence you should waive any applicable contingencies in the PSA. Does this mean after performing appraisal, inspection, etc… everything checks out you waive the contingencies? The class is self paced and not moderated so I’m unable to ask the instructor.. your help is appreciated

It could mean either that or more likely it means to waive them upfront if applicable. 

For example, if I'm paying cash I don't need a loan contingency so I'd waive it. In that scenario I personally would also waive an appraisal contingency in that case as I'm not worried about what an appraiser says value is...I already decided it was worth $XXX and that's what I'll pay.
