Thanks for all the feedback. To give you the outcome, I followed up on the company and they actually do exist. They are registered with the Oregon Secretary of State. Called and talked with someone at the company ( as far as I know). Also verified with my attorney contact that this a legitimate way to transact business, but as he said for every honest deal there are 99 scams.
Ultimately I offered to use an irrevocable letter of credit through my bank which guaranteed the bank would obligated to pay if the terms of the agreement were met. When the seller declined that offer we walked away.
Again, appreciate the feedback.
