That would be the logical option.
...but remember, this is DSP.
Also just keep in mind that when the price of a house goes from $150k to $350k in 7 years its not guaranteed to keep going up. More than possible is that the Seattle real estate market either plateaus or crashes.
"it'll never happen" is what makes it happen. People who have been living/working for 2-3 decades and own their houses fully or have minimal debt. When they see that extra half a million dollars that lets them sell and move somewhere more affordable they do it.
Seattle has similarities to places like San Francisco where a lot of the software people are ditching at the moment:

There's a full website dedicated to just talking about the Seattle real-estate bubble:

It's very easy to pick and choose evidence and its impossible to say if it'll change quickly, but we all know that one of Phil's weakest points is his resistance to change, so by the time he knows about it it would've already happened.
He's made a nice profit on the house and should sell it, cover as much of his debts as possible, get rid of that stupid fucking CT condo and move somewhere cheaper and be happy leading a simpler life and being able to pay off his debts in 5-10 years instead of 100 years.
But he won't. It's the true & authentic way of Philipo Burnelli, passed down through generations, the secrets of which will never be understood by the common man. When his PS4 stops working and he finally takes time out of his pasta-making schedule and stretches his bad back that little bit extra to dust off his videogiochi collection will be when the dust, compounded by years of neglect, has formed on the internal circuits of the console to cause a short leading to a surge of current jolting through his body. The sustained electrocution will intensely vibrate his mammary glands and various folds of excess causing a historic calorific burn off and forming Philipo into the peak physical specimen. The crusted juices of the numerous ladies that have had the pleasure of experiencing the Burnelli love machine combine under the pressure of the electrical forces granting him immortality.
After this event he continues his kind and selfless acts of playing day 1 videogiochi releases and making batches of authentic pasta sauce from the blood of his detrattori who he tracks during the night and hunts during the day. For eternity.
