Quick help for Short Sale Rider form

[Jeremy M.]

I don't fully understand this part of the short sale rider form, can anyone help me out with which is best for me as the buyer:

4. Contingency time periods in the contract for title, survey and inspections, if applicable, shall (one box must be checked):
1. Begin as set forth in the contract(no change to contract terms intended).
2.Begin at such time that all parties have actual knowledge of lien holders approval or of Seller's waiver of the contingency for lien holders approval.

Im the buyer, and I have 5 day inspection contingency...which is best for me?
