You really think the people who got a <3.5% interest rate loan will let go of their properties in the next 5 years to purchase a 5%+ mortgage for a more expensive monthly payment? What incentive do they have?
I just let go of my 2.25% mortgage to move out to the boonies at 7%. It's painful but still makes sense given the cost of living difference between here and the insane Bay Area. I am admittedly gambling that rates will come back down to something at least in the middle within a few years, but who knows?
