US Housing & Mortgage Markets

The spring housing market is delivering a counterintuitive signal: inventory growth is decelerating even as prices face their first real downward pressure since the pandemic. No crash, no flood — just a slow-motion affordability squeeze with sharp regional edges.

Inventory: The Slowdown Nobody Expected

The headline from Mohtashami and McBride is convergent and striking: inventory growth is losing momentum. McBride's read of the March Realtor.com data shows national active listings at +8.1% year-over-year — actually a tick up from February's +7.9%, but the trend over the past year has been one of deceleration. Nationally, inventory remains 13.8% below typical 2017–19 levels, down from the 16.8% gap last month (meaning supply is slowly normalizing, but still hasn't recovered).

Mohtashami goes further: states like Florida, which some forecasters had pegged for near-2008-level inventory surges, are already running negative year-over-year. The feared wave of Sun Belt distress hasn't materialized. New listings were up only 0.7% YoY in March — barely a pulse heading into what should be peak spring supply season.

McBride's framing is important here: months-of-supply is above pre-pandemic levels nationally, meaning the balance has tilted toward buyers in aggregate — but it's the rate of change that's now reversing. That's a different story than the one many bears were telling six months ago.

Prices Under Pressure — But No Distress Wave

McBride is direct: a year-over-year price decline is possible sometime in 2026. The combination of above-normal months-of-supply and sluggish sales is doing what math says it should. But he's equally direct about the ceiling on the downside: most homeowners are sitting on substantial equity and locked-in low-rate mortgages, so a cascade of forced selling isn't the mechanism here. This is price softness driven by affordability exhaustion, not credit stress.

Regional divergence is pronounced. The Northeast continues to hold, with tighter inventory and prices still rising. Markets with larger inventory buildups — parts of the South and West — are seeing the most price pressure. Builders are caught in the middle: McBride flags that 2026 looks difficult for homebuilders, with too many completed homes sitting unsold, an oversized pipeline of homes under construction, and builders cutting prices to compete with an expanding existing-home supply. (The data picture here is incomplete — the government shutdown has delayed Census housing starts for both February and March, with that release now pushed to April 29.)

Rent vs. Buy: The Gap Is Real, and Shoppers Are Straddling It

Olsen's Zillow research gives the sharpest quantitative framing of the affordability bind. About 8% of for-sale shoppers on Zillow are simultaneously browsing rentals — "dual shoppers" whose behavior reveals the actual household-level trade-off better than any index comparison. For the homes these shoppers are actually considering, owning costs $415/month more than renting on a comparable property (20% down, including taxes, insurance, and maintenance). In San Jose, that gap exceeds $3,400/month.

The geographic concentration is telling: dual shopping peaks in Los Angeles (12%), San Diego (10.8%), and San Francisco (10.1%) — markets where the median household would need to spend roughly two-thirds of income on a mortgage payment, versus about one-third to rent. These aren't marginal hesitations; they're structural barriers. Dual shoppers are consistent in what they want (3-bedroom homes dominate across both search modes) but are being forced to negotiate on size — the rentals they consider average 284 square feet smaller than the for-sale homes they browse.

Erdmann's Structural Argument: The Crisis Is Upstream of All of This

While others focus on current-cycle data, Erdmann is situating the moment in a longer arc. His provocation: total residential real estate value is roughly 50% higher relative to total personal income than it was for most of the 20th century. That's not a cycle; that's a structural deformation. He argues the root cause — supply-constrained urban land markets with inflated rents — has been systematically misdiagnosed by economists who blamed mortgage access, low interest rates, or federal subsidies. The Financial Crisis framing, in his view, sent a generation of analysts looking in the wrong direction.

His sharpest point: the crisis is no longer confined to coastal superstar cities. Phoenix, Atlanta, and Cincinnati are now in the frame. Erdmann's concern is that the pundits who do acknowledge supply constraints still overweight demand-side factors and remain skeptical about inland encroachment — meaning policy and advocacy remain misaligned with the actual problem. The Olsen data on Millennials being priced out of ownership in the $415-to-$3,400/month range is, in Erdmann's framing, exactly what inflated urban land rents look like from the ground level.

Synthesis

The mid-April picture is one of suspended tension. Supply is growing, but slower than expected — and the expected regional blowouts (Florida) haven't arrived. Prices are softening in aggregate but the mechanics are affordability-driven, not distress-driven, which limits the downside. Builders are under real pressure, a dynamic we'll know more about when the delayed Census data lands April 29. And at the household level, the rent-vs-buy math has become so unfavorable in major metros that a measurable share of active buyers are keeping rental options open as a live alternative.

Erdmann's structural argument is the backdrop against which all of this plays out: the affordability crisis isn't a cyclical aberration to be corrected by rate cuts or time. It's a land-supply problem that has been compounding for decades and is now visibly spreading inland.

TL;DR - Inventory growth is decelerating — active listings +8.1% YoY nationally but the trend is slowing, and Florida is already negative YoY, defying crash forecasts. - Prices face downward pressure in 2026 but no distressed-selling cascade is likely; equity buffers and locked-in low rates are holding the floor, with sharp regional divergence favoring the Northeast. - The rent-vs-buy gap is concrete and large — Zillow's dual-shopper data shows owning costs $415/month more than a comparable rental nationally, rising to $3,400+ in San Jose. - Erdmann's structural case: residential real estate is ~50% overvalued relative to historical income norms, and the supply-constraint root cause remains politically and analytically underaddressed even as it spreads beyond coastal metros.
