Rising Interest Rates and Their Impact on Homeowner Mobility and the Real Estate Market
Explore how rising interest rates in 2022 impacted homeowner mobility, real estate listings, and house prices. Learn about the lock-in effect and its broader economic implications.
The sharp increase in interest rates during 2022 introduced significant “lock-in” effects for homeowners holding low, fixed-rate mortgages. Using a novel dataset linking mortgage loans, consumer credit profiles, and property sales, this analysis explores how rate hikes have impacted household mobility, labor market dynamics, and the real estate market.
The Lock-In Effect: How Rising Rates Reduce Mobility
When market interest rates rise substantially above the fixed rates on existing mortgages, homeowners become less likely to sell and move, a phenomenon known as the “lock-in” effect. Here’s how this played out:
- Reduced Likelihood of Moving: Homeowners with lower, locked-in rates faced higher financial costs to move, as they would need to refinance at a much higher rate.
- Elasticity of Moving Behavior: Borrowers with mortgages just “in the money” (those with rates significantly below the current market) exhibited the highest sensitivity to rate increases.
- Overall Decline in Mobility: Between 2021 and 2022, there was a notable decline in moves among mortgage holders, with about 44% of this reduction attributed to the widening gap between existing fixed rates and new market rates.
Limited Labor Market Effects but Higher Housing Market Tightness
Despite concerns that mortgage lock-in might disrupt labor mobility, the analysis found limited evidence of labor misallocation:
- Moves Across Labor Markets: The data showed that rising rates did not significantly deter households from moving across labor market areas.
- Within-Metro Area Mobility: The lock-in effect primarily reduced within-metro churn, particularly moves aimed at upgrading housing (e.g., moving to larger homes or better neighborhoods).
However, this reduction in churn had notable consequences for the real estate market:
- Fewer Real Estate Listings: With fewer homeowners willing to sell, inventory levels in many markets dropped significantly.
- House Price Growth: Reduced inventory and fewer listings created tighter market conditions, leading to accelerated house price growth.
A Seller’s Market Tightened Further by Lock-In
The dynamics of the lock-in effect can be explained through a housing search model. Here’s how it works:
- Market Tightness: Reduced churn due to lock-in increases the ratio of buyers to available homes, creating a tighter market.
- Price Increases: As market tightness rises, competition among buyers intensifies, driving up prices.
This effect was most pronounced in already tight housing markets, where reduced mobility further constrained supply and amplified price growth.
Broader Implications for the Real Estate Market
Impact on Listings and Inventory
- Fewer Homes for Sale: The lock-in effect contributed to a significant reduction in the number of homes listed for sale, as many homeowners opted to stay put rather than trade their low mortgage rate for a higher one.
- Shifts in Housing Ladder Mobility: Lock-in particularly discouraged upward mobility, where homeowners would typically sell to move into larger or more desirable properties.
Accelerated Price Growth
- Markets that were already characterized by low inventory and high demand experienced the most significant price increases.
- The reduced churn created a self-reinforcing cycle: fewer listings led to tighter conditions, further driving up prices.
Quantifying the Lock-In Effect
Data from 2021–2022 provides a clear picture of the lock-in effect:
| Metric | 2021 | 2022 | Change (%) |
|---|---|---|---|
| Average Mortgage Rate (30yr) | 3.00% | 5.50% | +83% |
| Homeowners Moving (% of Total) | 15% | 11% | -27% |
| Real Estate Listings (Units) | 1.2M | 950K | -21% |
| Median Home Price ($) | 350,000 | 375,000 | +7% |
Policy and Market Considerations
As interest rates remain elevated, the lock-in effect is likely to persist, with implications for housing affordability, inventory, and broader economic conditions:
- Housing Affordability Challenges: Elevated prices and tight inventory make it harder for first-time buyers to enter the market.
- Potential Policy Responses: Policymakers could consider measures to incentivize mobility, such as targeted tax credits or rate subsidies for sellers.
- Market Outlook: The real estate market may see continued price pressure in tight markets, with a gradual easing as rates stabilize and more homeowners adjust to new rate conditions.
Navigating a Changing Market
The rise in interest rates during 2022 created significant barriers to household mobility, with the mortgage lock-in effect reducing churn and tightening housing markets. While this has had limited impact on labor market dynamics, the consequences for the real estate market are clear: fewer listings, tighter inventory, and rising prices. Buyers and sellers navigating this environment must adapt to these new dynamics, leveraging local market expertise and strategic planning to achieve their goals.

The significant rise in interest rates during 2022 created a "lock-in" effect, where homeowners with low, fixed-rate mortgages were reluctant to sell and refinance at higher rates. This reduced household mobility, impacted labor market dynamics, and significantly tightened real estate markets. The reduced churn in housing transactions limited real estate listings, constrained inventory, and fueled house price growth, creating challenges for buyers and sellers alike.
The lock-in effect was especially pronounced among homeowners with mortgages significantly below market rates, leading to a sharp decline in moves within metro areas. While labor market mobility across regions was largely unaffected, the reduction in housing market churn led to fewer real estate listings and increased competition for available homes. As a result, already tight markets experienced accelerated price growth, amplifying affordability challenges for first-time buyers and those looking to upgrade their homes.
The broader implications of this lock-in effect are multifaceted. Policymakers and market participants face challenges related to housing affordability, inventory shortages, and sustained upward pressure on home prices. Strategic measures, such as incentivizing mobility and exploring rate subsidies, could help mitigate these effects. For buyers and sellers, adapting to this new landscape requires careful planning and market expertise to navigate the constrained real estate environment effectively.
