Rent vs. Buy: The Math of Homeownership, Part 2

Rents rise with inflation — typically 3% to 5% a year — while a fixed-rate mortgage locks your principal and interest for the full 30-year term. Opendoor's 2026 comparison puts it plainly: a fixed-rate mortgage locks your principal and interest payment for 30 years, while rents rise with inflation, and over a decade that gap becomes significant.

This matters more in a state like North Carolina, where the economy is growing fast enough to keep pushing housing demand up. Novo Nordisk is midway through a $4.1 billion expansion that will add roughly 1,000 jobs, and Johnston County is among the fastest-growing counties in the state. That kind of job growth is a demand tailwind for both rents and home values — which is precisely why locking your housing cost while it's affordable is the defensive financial play.

Mini-verdict: A fixed-rate mortgage is an inflation hedge that your rent check never is, and it's most valuable in a market where wages and housing demand are climbing together.
