Recently while working with a client purchasing at the Escala, I ran into some questions about preferred lenders in general and it looks like the Seattle Times did a little blurb on the topic today.
Although preferred lenders often offer incentives like a credit towards the buyers closing costs, it is always best to get a second opinion from an outside source as there could be other financing options that would better suit your needs.
If you are seeking advice or another opinion, let me know and I can put you in touch with someone who can assist you!
