Housing inventory growth is nearing zero — and could turn negative as mortgage rates hover below 6.5%

National housing inventory rose by just 1,517 units in the week of April 3–10, 2026, compared to a 11,263-unit rise the same week in 2025. That gap isn’t noise — it’s momentum shifting toward a likely negative year-over-year inventory reading by mid-2026. The brake on supply isn’t sudden. It’s been tightening since mortgage rates settled below 6.5%, reducing the urgency for homeowners to trade up or cash out. Rates ended the week at 6.39%, down from 6.43%, and have not crossed 7% in months — a level that historically pushes more sellers into the market. But in 2026, even with brief spikes toward 6.64% due to the Iran conflict, the rate curve has been the lowest since 2022. That stability keeps sellers sitting. New listings last week totaled 70,244, down from 76,271 the same week last year. That shortfall follows a trend: despite seasonal expectations of 80,000–100,000 new listings during peak months, the market has not seen a single week in that range. Inventory growth has decelerated from 33% year-over-year in mid-2025 to just 3.21% in early April 2026. The slowdown isn’t isolated. Pending sales fell to 68,864 last week from 71,632 a year earlier. Purchase applications were down 7% year over year, despite a 1% weekly gain. The 10-year yield, which ended the week at 4.32%, has held below levels that would push mortgage spreads wider. And while spreads closed at 2.05% — down from 2.11% — they remain better than 2023–2025 peaks. Had 2023’s worst spreads applied today, mortgage rates would be 7.45%, not 6.39%. But the current environment isn’t punishing borrowing — it’s freezing movement. If trends hold, national housing inventory could post negative year-over-year growth by mid-2026.
