Buying a home has become a stubborn problem for American households, and a growing risk for the companies that build and finance homes. Since January 2020, estimated monthly mortgage payments on a median-priced resale home have surged 97%, according to John Burns Research & Consulting, while income rose 33% and home prices climbed 48%.

With affordability emerging as a campaign issue ahead of the November midterms, the pressure extends to Wall Street's housing stocks.

Mortgage Costs Outrun Income

The chart, posted by Rick Palacios Jr., Director of Research at JohnBurns, estimates payments on a median-priced resale home with a 5% down payment and a 30-year fixed-rate mortgage, including mortgage insurance. It captures the squeeze created by higher home prices and borrowing costs that remain elevated compared with 2020.

Buyers do not pay home prices in isolation; they finance them month after month. A home that looks moderately more expensive can require a dramatically larger payment when mortgage rates rise. Harvard's Joint Center for Housing Studies has likewise found that high prices and interest rates are keeping ownership costs near record levels and depressing demand.

Homebuilders Feel the Squeeze

The strain is showing up in builder sentiment. In October, the National Association of Home Builders' confidence index fell to 29, its lowest since June 2012, as mortgage rates, material costs and labor constraints weighed on the outlook. Reuters reported that 43% of builders cut prices and 65% offered sales incentives. The report highlights the trade-off for D.R. Horton, Inc. (DHI), Lennar Corp (LEN) and PulteGroup, Inc. (PHM): defend margins or make homes more affordable to keep sales moving.

Incentives can support demand, but they raise questions about profitability if discounts become a lasting feature of the market. Builder earnings may offer investors a read on whether buyers are returning, or responding to bigger concessions.

An Election-Year Pressure Point

Housing affordability is becoming a campaign issue ahead of the Nov. 3 midterm elections. Candidates are pitching responses including building more homes, reducing construction barriers and expanding buyer assistance. HousingWire's review shows the debate spans supply-focused proposals and measures targeting investors or helping buyers financially.

For investors, political attention matters because housing policy can affect construction costs, supply, financing and demand, though the timing and direction of changes remain uncertain. The chart alone does not predict election outcomes or identify which stock will outperform.

Lower mortgage rates could help, but may not erase the gap between incomes and homeownership costs. Until monthly payments become more manageable, builders must balance sales against margins, while investors watch for evidence that affordability is improving rather than simply being subsidized.
