Housing Supply Problem Tied to Buyer-Listing Mismatches

The housing market is experiencing a significant supply problem, which is often measured solely by the number of available units and listings. However, a deeper analysis reveals that the revenue generated within the housing industry stems from transaction "movement" – encompassing applications, showings, contracts, loans, inspections, appraisals, title orders, and closings – rather than just the existence of homes. Construction contributes to the physical stock of housing, but it is the effective matching of buyers to properties that drives market activity. This distinction is particularly relevant in the current economic climate, where existing-home sales remain at near three-decade lows, despite some improvement in inventory levels from their pandemic-era nadir.

According to NAR's Housing Mismatch Report, the alignment between available property listings and the financial capacity of households seeking to purchase them is significantly below pre-pandemic benchmarks. This indicates that the market's deficit is not merely a quantitative lack of homes, but a qualitative issue of insufficient homes that match the financial capabilities of potential buyers. A home that is listed for sale may not effectively function as usable supply for a specific household if the associated costs exceed their financial limits. These costs include the monthly mortgage payment, cash required for closing, property taxes, homeowner's insurance, private mortgage insurance (PMI), or homeowner's association (HOA) fees. Furthermore, the availability of suitable financing programs, the need for repairs that the household cannot afford, or even factors like commute times and the number of bedrooms can render a listing unsuitable.

This leads to a more refined definition of housing supply: "payment-qualified inventory." This refers to the set of homes that a household can realistically finance, afford to maintain, close on, and occupy under at least one permissible financing structure. This concept moves beyond a simple price-based search, which can lead to significant inaccuracies. A price-first approach can result in "false positives," where a home appears affordable based on its listed price but becomes unaffordable once all associated payment and cash requirements are factored in. Conversely, it can also lead to "false negatives," where a home is overlooked because its listed price falls outside the buyer's initial search parameters, even though it could have been a viable option due to lower property expenses, potential seller contributions, the availability of an assumable mortgage, down-payment assistance programs, or renovation financing options.

The core issue is that the market is not just short on houses, but short on houses that are financially accessible to a broad range of households. The current system, which heavily relies on transaction volume and revenue from movement, inadvertently creates friction when the financial qualifications of buyers do not align with the costs associated with available listings. Addressing this mismatch requires a more nuanced understanding of supply that prioritizes payment qualification, thereby unlocking more listings as usable supply and facilitating greater market activity.
