The cost to build a new home is soaring due to inflation and labor shortages. This "replacement cost" acts as a price floor for existing homes. This mirrors the 1970s, when home values tripled even as mortgage rates doubled, suggesting that long-term fixed-rate debt on property is a powerful inflation hedge.

As mortgage rates fall, more homeowners will list their properties, increasing inventory. This rise in supply will happen concurrently with the rise in demand from improved affordability. This dynamic will prevent a surge in home prices, keeping annual appreciation capped at a modest 2% for the upcoming year.

The historically low number of home sales isn't just about buyer affordability. A major factor is seller reluctance; existing homeowners are "locked in" by their low-rate mortgages and find it financially unattractive to sell and buy a new property at current higher rates.

While lower mortgage rates typically boost buyer demand, they also reduce the 'lock-in effect' for existing homeowners. This brings more supply to the market, which will likely offset the increased demand and keep home price growth minimal and 'range-bound'.

Jason Oppenheim contends that today's housing debate is misdiagnosed. The core issue is high interest rates impacting purchase power. He argues that when analyzing rents, the percentage of income required for a comparable unit has remained stable for decades.

Fed rate cuts primarily lower short-term yields. If long-term yields remain high or rise, this steepens the curve. Because mortgage rates track these longer yields, they can actually increase, creating a headwind for housing affordability despite an easing monetary policy.

A major driver of today's housing scarcity is that homeowners, particularly Boomers, who refinanced into sub-3% mortgages have no financial incentive to ever sell. This seemingly positive economic condition has had the negative side effect of locking vast amounts of housing inventory in place, worsening the supply crisis.

The gap between existing mortgage rates (under 4.25%) and new rates (over 6.25%) is over 200 basis points. This spread, which disincentivizes homeowners from selling, has persisted for three consecutive years. Historically, the gap only exceeded 100 basis points for a total of eight quarters over the past four decades, making the current situation a major anomaly.

While lower interest rates seem appealing, they often fuel intense market competition and bidding wars. Higher rates can thin the herd of buyers, providing an opportunity for those who can still afford to purchase to secure a deal with less pressure and more negotiating power.
