The Rise of Assumable Mortgages: A Path to Lower Rates Amidst Challenges

Assumable mortgages are emerging as a method for homebuyers to secure lower interest rates by taking over a seller's existing mortgage. This innovative approach allows buyers to acquire homes with rates potentially below 3%, sharply contrasting with current average rates for 30-year fixed mortgages.

Types and Prevalence

While the majority of conventional mortgages are not assumable, government-backed loans, such as VA (Department of Veterans Affairs) and FHA (Federal Housing Administration) loans, are typically eligible for transfer. An estimated 6 million homes in the U.S. currently have assumable mortgages with interest rates under 5%. In 2020, approximately 18% of new mortgages originated were VA and FHA loans, contributing to this pool.

Challenges in the Transfer Process

Despite the attractive potential benefits, several significant challenges currently hinder the widespread adoption and smooth execution of assumable mortgages:

Lack of Awareness

Many homeowners and potential buyers remain unaware that a mortgage can be transferred. Specialized platforms, including Assume List, Assume Loans, and Roam, have been developed to identify and facilitate these unique transactions. These companies often report a substantial disparity between the number of self-reported assumable listings on general real estate sites and their own verified findings.

Servicer Delays

Mortgage servicer companies are legally obligated to evaluate a buyer's credit for transfer approval within 45 days. However, this process frequently extends for several months. Industry observers suggest that servicers may be more inclined to prioritize new loans at higher current rates over facilitating the transfer of older, lower-rate mortgages, despite FHA guidelines allowing up to $1,800 in fees for the transfer process.

Substantial Down Payments

Home prices have seen a significant increase, rising 54% since January 2020. This surge in value creates a substantial gap between the existing mortgage balance and the current market value of the home. Consequently, buyers often need to cover this difference with a large cash down payment, which can amount to hundreds of thousands of dollars. This considerable upfront cost can severely limit accessibility for many, particularly first-time homebuyers.

Impact on the Housing Market

Proponents argue that increasing the availability of assumable mortgages could play a crucial role in alleviating the current housing market gridlock. Many homeowners who currently enjoy low interest rates are reluctant to sell, a factor contributing to a near 25-year low in U.S. housing turnover.

The Groundwork Collaborative suggests that making more conventional mortgages assumable, or allowing "portable" mortgages (where sellers can take their low rate to a new home), could address housing unaffordability in the short term.

Further signaling potential shifts, Federal Home Financing Agency Director Bill Pulte indicated in November that Fannie Mae and Freddie Mac were actively considering assumable or portable mortgage options.

Conversely, some experts, such as Laurie Goodman of the Urban Institute, believe that the requirement for large cash down payments inherently limits the potential impact of assumable mortgages on the broader market. Despite these significant barriers, companies assisting with transfers report continued strong demand from buyers willing to overcome the hurdles to secure a lower interest rate.
