Mortgage rates have risen for five consecutive weeks, reaching their highest level in seven months. The Iran war, which began just over a month ago, is rewriting housing mathematics in the United States, creating a paradox that defies traditional market expectations. While home prices show signs of moderation and inventory increases, financing costs have spiked, partially neutralizing the affordability improvements that should be driving sales activity in what is typically the busiest season for housing.

The Big Picture

American housing faces an unexpected paradox in spring 2026. On one hand, March data shows conditions that should favor buyers: more inventory, lower prices, less time pressure. On the other, sales remain muted because the cost of money has spiked just as affordability appeared to be improving. This divergence creates a strangely bifurcated market where both buyers and sellers face unique challenges that complicate traditional spring selling season dynamics.

The conflict in Iran has reversed a key trend that had been developing since late 2025. Before the war, the 30-year fixed mortgage rate had been on a long, smooth decline, even dipping below 6% for the first time in 3.5 years. This decline had generated optimism among buyers and had begun to reactivate a market that had been stagnant due to 2024's high rates. Now, inflation fears stoked by the conflict have pushed rates steadily upward, adding a layer of geopolitical uncertainty to home purchase decisions at a critical seasonal juncture.

This turn comes just as the market showed signs of equilibrium after years of extreme scarcity. The COVID-19 pandemic and its aftermath had created extraordinary market conditions, with prices soaring more than 40% in some markets between 2020 and 2023. The normalization that began in 2024 is now complicated by external factors that are rewriting the rules of engagement. Buyers who expected to capitalize on lower prices are finding that monthly payments remain elevated due to the rate increase, creating a mathematical barrier to entry even as listing prices decline.
