The housing market has an unusual anchor: millions of homeowners who refuse to trade their legacy loan terms. A national survey from Best Interest Financial and Clever real estate found that 35% of mortgage holders with rates under 6% would not sell for any price, and that number rises to 52% for those sitting on sub-3% loans. Nearly 47% of respondents said they could not afford a mortgage at today’s rates if they had to start over.
This phenomenon — often called the lock-in effect — is shrinking turnover, tightening supply, and changing the calculus for anyone looking to buy or rent properties.

Why homeowners prefer to stay put
Several data points explain why many owners are reluctant to move. According to the Intercontinental Exchange, roughly 54% of primary homeowners carry rates at or below 4%, a deeply advantageous position compared with current market pricing. Since 2026, annual existing home sales have dipped to about 4.1 million, the lowest level in decades, reflecting a market with far fewer listings. At the same time, older generations — especially baby boomers — are driving a disproportionate share of transactions: they account for a sizable portion of buyers and sellers, and often use accumulated equity to finance moves that are optional rather than necessary. That dynamic leaves younger buyers squeezed between high prices and limited inventory.
Mortgage rates and the stalled market
Higher borrowing costs are a central reason turnover is muted. The 30-year fixed mortgage rate has hovered near the mid-6% range — a level that keeps many would-be buyers renting or postponing purchases. The Mortgage Bankers Association has signaled a range between 6% and 6.5% this cycle, and some market snapshots cited a national 30-year average near 6.37%. Those rates, combined with falling monthly sales — a roughly 3.6% drop in one recent monthly reading that pushed activity to a multi-month low — have frozen some sellers in place. Conversely, builders of new homes have been able to incent buyers: new-construction sales recently rose more than 7% month-to-month, with developers offering discounts that can lower effective costs.
What this means for landlords and renters
With fewer homes changing hands, many households priced out of purchase wind up in the rental market, making rental property a coveted asset. The combination of constrained supply and steady population needs supports continued interest in rental holdings. Recent rental tracking shows mixed short-term movement: rents ticked higher month over month in one April report, while year-over-year figures were modestly lower by about 1.7%. Sentiment among landlords has softened slightly in some surveys, but structurally the case for owning rental property remains strong because housing is an essential good and inventory is tight.
Investor views and risk management
Industry analysts emphasize that in this environment real estate often behaves more like an income asset than a pure growth play. Research leaders suggest focusing on steady cash flow and fundamentals over speculative price gains. Observers note that higher rates are only one part of the investment equation; macroeconomic context, occupier demand, and regional resilience matter too. Financial planners and researchers recommend treating property as a diversifier and potential inflation hedge, but they also urge careful underwriting: factor in vacancy risk, maintenance, and local demand drivers before acquiring assets.
Where to look and practical takeaways
Location selection is key. Analyses from national platforms point to stronger opportunities in the Midwest and Sunbelt, where affordability remains comparatively favorable and entry prices are lower than on high-cost coasts. Many investors are advised to avoid the most expensive metros — such as San Jose, San Francisco, and the New York tristate area — unless they have an edge. Policymakers and private estimates differ on the scale of the shortfall: some put the housing shortage near ten million units, while other assessments are more conservative. Regardless of the precise number, the underlying theme is consistent: limited inventory plus healthy demand creates a tailwind for well-managed rental investments.
Bottom line: the mortgage lock-in has created a supply-side constraint that benefits landlords but complicates homebuying for many. For investors able to acquire and operate rental properties with disciplined underwriting, the current market offers durable income potential. Still, prudent investors will prioritize markets with strong job bases, affordable entry prices, and realistic stress-testing of cash flows. In short, this is not a moment for scattershot purchases but for targeted buys backed by conservative assumptions and a long-term view of rental income.
