The Real Reason You Can't Afford a House

SUMMARY

Patrick Boyle examines the underlying reasons for skyrocketing house prices and the resulting affordability crisis, using New Zealand as a case study to illustrate global trends. He explores the roles of political incentives, interest rates, land value, and restrictive housing policies in shaping property markets and their broader economic impact.

MAIN POINTS

• A dilapidated Auckland home sold for 1.81 million NZD, illustrating extreme housing unaffordability and the onset of a sharp market decline. [1:00]
• Land value, not the physical house, drives property price increases, as highlighted by Henry George's 19th-century economic theories. [6:01]
• Falling interest rates over four decades enabled buyers to borrow more, inflating home prices, while recent rate hikes have sharply reduced affordability. [12:00]
• Restrictive planning laws and political reluctance to allow new development have exacerbated housing shortages in countries like the UK and US. [18:02]
• Young professionals are emigrating from high-cost countries such as New Zealand and the UK, undermining the future workforce and economic growth. [21:01]
• Housing busts force policymakers to choose between slow, painful declines or rapid corrections, with both approaches carrying significant economic consequences. [26:00]

DETAILED ANALYSIS

Housing affordability has reached crisis levels in many developed countries, exemplified by the sale of a severely dilapidated property in Auckland for nearly two million New Zealand dollars at the peak of the market. This extreme pricing, at 35 times the median income, was unsustainable and led to a sharp correction, with real home values dropping by about a third in some regions and many recent buyers facing negative equity. The situation in New Zealand serves as a microcosm for broader global trends, where housing markets have been shaped by the political imperative to maintain rising property values.

Politicians, incentivized by the voting power of homeowners—who are typically older and more likely to vote—have consistently supported policies that inflate home prices. These include mortgage subsidies, tax breaks for landlords, first-time buyer grants, and restrictive zoning laws that limit new construction. While these measures are often presented as ways to improve affordability, they generally have the opposite effect, making homes more expensive and entrenching wealth among existing owners.

The economic distinction between productive assets and residential property is crucial. Unlike investments in businesses, which generate new wealth through innovation and employment, rising land values simply transfer wealth from new buyers to existing owners without increasing overall economic productivity. This dynamic was articulated by Henry George in the 19th century, who advocated for a land value tax to capture unearned increases in land value for public benefit.

Although his proposal remains debated, the core observation endures: land appreciates due to community development, not individual effort.

The long-term rise in home prices has been heavily influenced by declining interest rates. As mortgage rates fell from around 20% in 1981 to historic lows near 2.65% in 2021, the same monthly payment allowed buyers to borrow much larger sums, driving up prices. However, when interest rates began to rise again, affordability plummeted.

For example, a buyer able to spend $1,500 per month could borrow $370,000 at 2.65% but only $236,000 at 6.5%. This rapid shift has frozen housing markets, particularly in the United States, where 30-year fixed-rate mortgages allow homeowners to stay put and avoid higher rates, while countries with floating or short-term fixed rates, like New Zealand, have seen immediate increases in mortgage payments and a quicker market downturn.

Restrictive planning and zoning laws further exacerbate the crisis by limiting new housing supply. In the UK, for instance, planning legislation dating back to 1947 has constrained development, resulting in persistent shortages and a broken 'property ladder.' Similar regulatory hurdles exist in the US, where even disaster recovery efforts often require rebuilding the same types of homes rather than adapting to current needs. The political focus on protecting existing homeowners' wealth discourages reforms that would increase supply or lower prices.

The consequences extend beyond housing markets. As affordability declines, young professionals increasingly emigrate in search of better opportunities, as seen in the significant outflow from New Zealand to Australia and similar trends in the UK and US. This demographic shift undermines the future workforce and economic growth, as productive cities become prohibitively expensive for new talent.

The inefficiency of property markets raises business costs, drives capital elsewhere, and ultimately weakens national economies.

When housing bubbles burst, policymakers face difficult choices. The Japanese approach after 1991 involved a slow, managed decline, resulting in decades of stagnation, while the US and Ireland experienced rapid, painful corrections after 2008 but eventually saw markets reset and capital redirected to more productive uses. The underlying issue remains the widespread treatment of homes as investment vehicles rather than places to live, a strategy that is unsustainable in the long run and requires fundamental changes to restore affordability and economic vitality.
