Initially they balked, but eventually they relented* We kept our inspection contingency to void (not negotiate), and included a financing contingencyHow did you finance this deal?

NOTE:  there may be some tax on interest or principal on the payments--seek professional advice.Also, stress there will be no inspections or other contingencies--sell the 'peace of mind' side of the equation.You have known each other for 12 years and you established you are a great payer. 

We currently target deals that fall through and then make a no-contingency cash offer to hold their original closing date.

I've offered "as-is" several times but with the only contingency being sewer scope because it was the only remaining unknown.

The agent can also recommend professionals to help you assess your costs before you offer or during an inspection contingency.

Offering a quicker closing timeline or adding contingencies that reassure the seller can also help make a lower EMD more appealing.

The reason is for that amount, that's all the attorneys would do on a contingency basis, and they only charged a fee if they collect on a lawsuit, The customer then asked if I would pay him a few dollars instead.
