"Convinced"?
The mere fact that, by mid-2010's the region (Boring's area) started being flooded with leftardoid "immigrant" scum from Portland and other neighboring places, mostly chink and spic in origin, absolute majority of which were criminals. QoL situation worsened, because arrogant litterers, heavy druggies, prostitutes and whores, arsoners, and straight up just rapists and murderers, gang members, thugs, started coming in. This was not a thing before 2010, the place was safe, clean, and absolutely fine.
We, as a family, already started packing things slowly by late 2010, but decided to "wait it out" and observe the situation, yet were essentially forced to leave, in 2011. At first, we tried to settle in other States, specifically so our most favorite/beloved ones - Vermont and Tennessee, but we found out that we weren't able to afford to purchase property/real estate there that would've at least equaled what we had in Boring/Oregon, even with extra savings me and other family members had, prices for house space per sqm were exorbitant in Tennessee and Vermont, especially so the latter, which almost doesn't have any decent enough offerings without obligatory pushing of "free" additional land lots in the same package, which we never needed, and we knew how inane the "free land" taxation is.
Basically, after moving about for a bit, not finding anything suitable enough, we left the country outright, by late 2011. My relatives and I still have full citizenship technically, and we still own that house in Boring, but since 2012 we've been only strictly renting it out to others remotely. We also still pay for all the expenses, bills and taxes remotely, as well. The renters only pay the rental fees.
