Buy-to-Let vs Index Funds: Which Makes You Richer?

Key Concepts

• Real Returns: Investment returns adjusted for inflation, reflecting the actual increase in purchasing power.
• Capital Gain: The increase in the value of an asset over time.
• Rental Income/Yield: The income generated from renting out a property, analogous to dividends from stocks.
• Volatility: The degree of variation of a trading price series over time, indicating risk.
• Risk-Adjusted Return: A measure of the return on an investment relative to the amount of risk taken.
• Liquidity: The ease with which an asset can be converted into cash without affecting its price.
• Transaction Costs: Expenses incurred when buying or selling an asset (e.g., stamp duty, legal fees, commissions).
• Holding Costs: Ongoing expenses associated with owning an asset (e.g., maintenance, insurance).
• Leverage: The use of borrowed money to increase the potential return of an investment.
• Equity Risk Premium: The excess return that investing in the stock market provides over a risk-free rate.
• REITs (Real Estate Investment Trusts): Companies that own, operate, or finance income-generating real estate.

Long-Term Historical Returns: Property vs. Stocks

Data Sources and Findings

• Rate of Return on Everything Database: A comprehensive dataset compiled by economists including Yorda, Null, Kushinov, Schillaric, and Taylor, tracking 16 countries over 145 years.
  • Real Returns: Both housing and equities delivered approximately 7% annual real returns (after inflation).
  • Bonds: Managed significantly lower real returns of around 2-3% per year.
• Importance of Rental Income: For housing, rental income constituted more than half of the total return across all countries in the study. This contrasts with equities, where capital gain typically exceeded income.
• Volatility: Housing was found to be half as volatile as stocks, suggesting a smoother ride for property investors over the long term.
• Risk-Adjusted Returns: Considering volatility, housing offered more units of return for every unit of risk compared to stocks.

Specific Indices and Observations

• K Schiller Index (US Housing): Tracks US home prices since 1890 but only considers price changes.
  • Real Return (since 1987): Showed a modest 1.5% based solely on price appreciation.
• UK Nationwide House Price Index: Also focuses on capital gain.
  • Real Terms (recent past): Prices are roughly at the same level as almost 20 years ago.

Differentiating Homeownership and Investment Property

• Homeownership:
  • Benefits from capital gain (house value increase).
  • No income generated while living in the property.
  • Financial payoff is realized only upon sale or downsizing.
• Buy-to-Let Property:
  • Captures both capital gain and rental income.
  • Rental yield acts as the income component, similar to dividends on shares.
  • Transforms property from a static store of value into a true investment asset.
  • When rental income is factored in, total property returns align with equity returns.

Re-examination of Housing Return Data

• Chambers, Dimson, Ilman Manan, and Renter Maki (2024): Conducted a re-examination of the long-term housing data.
  • Critique: Argued that some global housing series might overstate returns due to:
    • Splicing of older price indices.
    • Inconsistent handling of quality improvements.
    • Extrapolation of rental yields backward in time.
  • Comparison: Micro studies with detailed transaction and rent records showed noticeably lower total returns compared to macro datasets.
• Consensus: Despite the re-examination, both camps agree that almost all of property's long-term reward stems from income, not price appreciation.
• Net Rental Yield: Authors suggest that net rental yield (after costs) likely sets a ceiling on expected future housing returns, rather than a floor boosted by perpetual real price growth.

Long-Term Equity Returns

• Dimson Marsh Storton Global Investment Returns Yearbook: Covers 35 global markets since 1900.
  • Global Equities: Averaged approximately 5-6% real return annually.
  • Bonds: Averaged 1-2% real return annually.
• Jeremy Seagull's "Stocks for the Long Run": Confirms similar consistent real returns of roughly 6-7% for US equities over two centuries.
• Property vs. Equities: The surprise historically is that property returns have kept pace with equity markets.

Real-World Investment Considerations: Property vs. Stocks

Liquidity

• Index Funds/ETFs: Can be sold in seconds, with funds typically available within one day.
• Property: Selling can take weeks or months, involving extensive processes and the risk of chain collapse. In a crisis, property markets can freeze, while stock markets offer exit opportunities.

Transaction Costs

• UK Property: Buying or selling can incur 5-10% of the property value (stamp duty, legal fees, estate agents).
• ETFs: Commission-free on many platforms, with bid-offer spreads usually less than 0.1%.
• Magnitude: The difference in transaction costs is an order of magnitude.

Holding Costs

• Property: Annual costs for maintenance, insurance, letting fees, and void periods can be around 1% of property value.
• Index Funds: Management fees are typically around 0.1%.

Tax Implications

• Stocks: Can be held in ISAs or SIPs for tax-free growth.
• Property: Subject to:
  • Stamp duty on purchase.
  • Income tax on rent.
  • Capital gains tax on sale.
  • Restrictions on mortgage interest deductibility (since 2017).
  • Inheritance tax (valued at market price at death, taxed at 40% above nil rate band).
• System Design: The tax system appears more favorable to homeowners than landlords.

Time Commitment

• Fund Portfolio: May require half an hour per month.
• Property Portfolio: Can feel like a second job, involving managing tradespeople, tenants, and safety checks. This "Return on Ass" (ROA) is often overlooked.

Leverage

• Mortgages: Magnify both returns and losses. A 20% fall in house prices can wipe out most equity on a 75% loan-to-value purchase.
• Equities: Leverage is inherent within companies, generally causing fewer sleepless nights.

Current Market Landscape (2025)

UK Property Market

• Mortgage Rates: Hovering around 5%, impacting affordability.
• Real House Prices: Currently flat.
• Gross Rental Yields: Approximately 5-8% (according to Zupller data).
• UK Government Bond Yields: Around 4-5%, with very little risk if held to maturity.
• Risk-Adjusted Appeal: Property's risk-adjusted appeal is weaker than it has been in a decade.

Global Equity Market

• AI Boom: Driving significant growth.
• S&P 500: Up in double digits year-to-date.
• Equity Risk Premium: Remains "alive and well" (UBS, 2024).

Takeaways for Portfolios

Historical Perspective

• Equities and Housing: Both have generated approximately 7% real return over centuries.
• Bonds: Around 2% real return.
• Cash: Around 1% real return.

Investment Strategy

• Diversification: Crucial; avoid being dogmatic about any single asset class.
• Incorporating Property:
  • Directly via buy-to-let.
  • Through Real Estate Investment Trusts (REITs).
  • Via listed infrastructure funds.
• Combining Investments: Low-cost global trackers can capture a broad spectrum of returns.
• Necessity of Property: Not strictly necessary for all portfolios.
• Personal Preference: Some find the comfort of rental income justifies the hassle of physical property ownership, acting as a bond-like component. The speaker personally prefers stocks and bonds.
