The Mortgage ‘Lock-In Effect’ Is Raising Your Rent Prices
The “lock-in” effect is causing many homeowners to stay put instead of moving, leading to an increase in housing costs. This trend stems from the low interest rates prevalent during the pandemic, which allowed homeowners to purchase property at incredibly cheap rates. Now, they are hesitant to sell or buy new homes due to the significant increase in mortgage rates.
According to a recent white paper from the National Bureau of Economic Research, the lock-in effect is impacting housing supply, demand, and prices. Close to 80% of mortgage holders had rates below 6% at the beginning of the year, but current rates are in the mid-6% range, making the jump intimidating for homeowners.
Melissa Cohn, regional vice president of William Raveis Mortgage, explains that it’s much easier for homeowners to adjust from a 4% to 5.5% rate rather than from 4% to 6.5%. As a result, those who are still moving are typically doing so due to life-cycle events like a new job or expanding family.
Another factor holding homeowners back is the capital gains tax they would have to pay on the sale of their homes. The current IRS guidelines allow for a tax exemption of up to $250,000 for a single seller and $500,000 for couples. However, these limits were set in 1997 when the median home price was $129,000, significantly lower than the current median price of $419,300.
The lock-in effect not only impacts homebuyers but also renters. With fewer homes for sale, prospective buyers turn to rental properties, increasing demand and driving up rental prices. Older homeowners and empty nesters who may want to downsize are also affected, as they opt to stay in their current homes due to high rates and potential tax implications.
Solving this issue requires adding more inventory to the market. While new construction can help, it alone cannot make up for the supply deficit. More existing homes need to be available to balance the market. However, as long as homeowners feel locked into their current mortgage rates, housing activity is likely to remain sluggish, especially for first-time and moderate-income buyers.
In conclusion, the lock-in effect is driving up housing costs and impacting both buyers and renters. Increasing inventory is crucial to unlocking the market and providing more options for prospective homeowners.
