With 50% down you shouldn't have any problem with financing. We would recommend beginning with the bank you normally do business with. They will be able to refer you to a US bank that might be able to provide the most favorable terms.
One of our customers from London, Onterio actually found a branch of his bank in our location with superior terms. Start with your own bank, it may be able to help more than you can imagine.
