Your best bet is going to be first finding a Realtor where you are looking to buy in Washington state and try the lender(s) they recommend first. A good Realtor always has at least one, if not three, lenders they work with all the time that they would recommend to buyers for both great loans and good personal customer service - both are equally important when buying a home.
