“Whereas renters are continuously vulnerable to cost increases, rising home prices do not affect homeowners. Nobody rebuys the same home every year. For the homeowner with a fixed-rate mortgage, monthly payments increase only if property taxes, and property insurance costs increase. The principal and interest portion of the payment, the largest portion, is fixed. Meanwhile, the renter’s entire payment is subject to inflation.
Consequently, over time, the homeowner’s and renter’s differing trajectories produce starkly different economic outcomes.
Homeownership’s major affordability benefit is that it stabilizes what is likely the homeowner’s biggest monthly expense, assuming a buyer has a fixed-rate mortgage, which most American homeowners do. The only portion of the homeowner’s housing expenses that can increase is taxes and insurance. The principal and interest portion stays the same for 30 years.”
