Youre banking 3k+/month into your asset now instead of paying someone elses off. You are making money every month instead of losing it. That alone should make you grin at the price difference.
The deep level of stability and control you get with home ownership should keep that grin going.
The fact, the utter fact, that Seattle rents will return to outpacing your mortgage shortly is something that should make you don clown makeup to begin a Harlequin dance of joy that you own a home in such a high COL area.
