What is large?
The "standard" EMD is 3% of the offer price. Less than that the seller is going to have questions about your earnestness. If you are an entry level buyer, and you are encountering multiple offer situations, then you need to strategize with your Realtor on how to get your offers accepted.
I work in PA and our agreement of sale does contain language that allows a buyer to select or to waive contingencies for various inspections and for financing. However the paperwork must be filled in correctly for those contingencies to be in effect.
Good luck with your home purchase!
