The Land Leverage Hypothesis

Property assets (housing) represent composite goods:

Housing = composite good = VLand = component = LBuildings = component = B

V = L + B


Land leverage reflects:the proportion of the total property valueembodied in:the value of the landas distinct from improvements (buildings)as a significant factor for establishing the future path of property prices


It follows that the value of land and value of improvements on that land are likely to evolve differently over time?

As economists we should not find this surprising ???


Intuition and economic theory suggest significant demand/supply asymmetry between land and improvement components

Demand/Supply Asymmetry

Demand side

Improvements = capital input in housing production

Land capitalises the market value of location and infrastructure (schools /shopping/employment centres

Why is this important ???

Housing affordability

A stylized example• Consider two homes, one located in Sydney and

the other in Adelaide, both homes are valued at $450,000

• The Sydney home is a cheaper home in an established area with older depreciated improvements worth $90,000 and land worth $360,000

• The Adelaide home is a higher-end home of new construction with an allocation of $360,000 to improvements and $90,000 to land value

A stylized example• Assume in one year economic fundamentals cause

land prices in both markets to increase by 10% (no depreciation and construction costs remain stable)

• The 10% increase in land prices translates into a $36,000 increase in the Sydney home, and overall appreciation for the home would be 8%

• In contrast, the same 10% increase in land values will only result in a 2% increase in the value of the Adelaide home

• Despite the same magnitude of change in land prices, house prices in Sydney would appreciate four times faster than those in Adelaide

A stylized example• In summary, the property in Sydney is highly

land leveraged, a similar influence to financial leverage

• Higher exposure to factors influencing land prices within markets has a more significant influence with increasing land leverage

• Land value becomes the major source of price appreciation and volatility

• Note if land values dropped by 10% the Sydney home would decline - 8% even though land values changed by the same proportion in both markets

Implications of Land Leverage (for big cities)?

Prices for housing are largely driven by changes in price of the land component

Older housing has higher land leverage than for new housing

Older housing will have higher growth rates than for newer housing

Implications of Land Leverage (for big cities)?

Trend growth rates for the building and land components are different

Land prices increasing = an increasingly important component of aggregate regional/national wealth

Data and Methodology

In order to calculate land leverage for an individual property, the value of the land must be identified separately from the value of the improvements

Some results for Perth 1988-2011

• Average land leverage 63% (63% land, 37% building)

• Average overall total property price change +12.3% p.a.

• Land component +13.9%

• Improvements + 8.7%

Some results for Perth

• Land values have grown at different rates throughout the Perth Metropolitan region (highly significant results)

• There is significant time variation in the influence of land leverage

• Most significant influence for land leverage = vacant lot purchases 1998-2006

What next ??

• How does this work in submarkets with large variations in the age of the housing stock?

• What happens when vacant land is also being sold in submarkets?

• Is there a special value for heritage property?• Do neighbourhoods exhibit specific

depreciation characteristics for housing stock?

Policy considerations1. Housing affordability

2. Measurement of house prices

3. Housing subsidy policy (rental markets)

4. Zoning policy - intensity of land-use
