I am Seattle & Lynnwood located here in Seattle.
Let's look at the property address first. How did you come up with the value? Zillow? Property tax assessment? It is all going to come down to the appraised value. I would be very conservative on this figure as appraisers haven't caught up with recent home sales. Especially in Snoho, as their is a lot of short sale & foreclosure still in the mix. Plus builders have ramped up their building again on all the farm land
Second, we've seen a huge pull back in rates since Sept 24th. Roughly a .375% rate hike. This has stemmed from increasing talk of the economy improving, Eurozone Summit and a drop in oil .
All that being said I would say today you would be at 4.125% on the 30yr. This is based off of the info provided below and no cash out( not paying off a 2nd loan)
