Mortgage Lock‑In Keeps Homes From Moving
USAThu May 21 2026
The housing market is stuck because most homeowners have cheap loans that they can’t easily replace. About eighty‑five percent of mortgages are under five percent, and many of those were set when rates were below three‑and‑a‑half percent. Today the normal rate is above six‑point‑eight, so selling a house means losing that low cost and buying another at a higher price.
If someone owns a four‑hundred‑thousand dollar loan at three percent, they pay about one thousand six‑hundred and a half dollars each month. Moving to a similar home with a loan at six‑point‑nine would raise that payment to about two thousand six‑hundred, a difference of almost one thousand dollars every month. That extra cost makes most people stay put unless something urgent forces a move, such as a job change or family need.
Because people are not moving, the number of houses for sale is very low. Sales have been near their lowest levels since the mid‑1990s, even though more families are forming and young people want homes. Low supply keeps prices high, and buyers can’t afford the steep price‑to‑income ratios that exist especially on the coasts.
Builders have tried to help by offering rate buy‑downs, where they lower a buyer’s mortgage rate for a few years or pay points at closing. These tricks make buying feel cheaper right away, but they do not change the overall high‑rate environment. New homes are mostly appearing in Sun Belt cities like Phoenix, Dallas, and Austin, where land is cheaper. Coastal areas, which have strict zoning rules and high construction costs, see almost no new supply.
The choice for sellers is simple: wait until rates drop enough that the lock‑in penalty disappears, or sell now and accept a higher cost. Those who need to move for reasons other than money can use the equity they already have as a cushion. Purely rate‑driven sellers find little relief in the near future because central bank policy suggests only a gradual, modest decline in rates.
The summer market will likely repeat the pattern of the last two years: very few homes available, strong prices in most places, and sales below what population growth would normally support. Buyers should plan for this reality instead of hoping the market will fix itself on its own.
