It can be a perplexing journey to your first Patek given your research regarding the variables you've encountered thus far.
Since you are in the US, I would encourage you to pursue obtaining your watch from an AD here in the US and one nearby if possible. I say this because of your age and interest. You would be the ideal client, meaning there is an opportunity to develop a long term relationship for you both. As a former dealer, I encountered many folks in the same position you've described, who recognized and appreciated the quality Patek offered but like most starting out in life, it was a financial struggle. I made every effort to help those to get to the watch they wanted and was successful in most cases. It wasn't easy because Patek expects their check promptly, certainly sooner than the purchase price would be paid.
Don't underestimate the value of the relationship with an AD. It can be something in the future which you would look back and be thankful for. It can be that important. Of course money is an issue, but there is much more to buying a Patek than just writing a check and getting the lowest price. That low price generally comes with baggage. An AD 12,000 miles from you makes most things an AD can and should do for you more difficult and more importantly, inconvenient for you.
I hope you find an AD who is willing to work with you to get your dream watch and ... more in the future.
I don't know if this is of any help but hope so.
