I realize Drafts are not the same as Negotiable Orders of Withdrawal... thank you Dave for presenting a scenario as to why the OP is having difficulty.
It's been decades since I've had an Insurance Settlement... I just send them money.
My last insurance claim was for a minor fender ding that the insured's agent wrote me a check on the spot for $92 and change. I walked across the street from the agents office to a Wells Fargo and cashed it.
I'm still concerned as to why the OP would need to have a large amount of cash at the open house in order to proceed with a possible home purchase?
Maybe it's a local custom???
A third option might be to have the Title Company Process the funds???
