Check with them, they are very experienced with foreign buyers and also are an "upfront" lender who will offer you the best interest rates and lowest "lender related" fees. Unfortunately some mortgage brokers who do not actually lend money many intentionally offer more than they can deliver, only to spring the surpirse on you a day or two before you're required to close. http://www.mtgprofessor.com is a valuable site, too.
p.s The guy posting that you should contact reputable banks will have you on a wild goose chase. That is the job of a broker. Thats like me saying "go look for a house from a reputable seller" just like a realtor, mortgage brokers help find you the best deal.
