Common mistakes about real estate

The common belief: Property is a one-way market that climbs regardless of the interest-rate environment.

What the data shows: Housing is a long-duration asset and historically tracks real-rate cycles with a lag. When the average 30-year fixed mortgage moved from a record low near 2.65% in January 2021 to above 7% in 2023 (Freddie Mac), borrowing capacity compressed sharply and existing-home sales fell. Prices and transaction volumes do not move together, and prices can stay elevated even as activity collapses.

The common belief: What a home costs is the sticker price, or at most the monthly payment.

What the data shows: The real cost includes interest, property taxes, insurance, maintenance (roughly 1-2% of value per year) and the opportunity cost of capital tied up in equity. In a high-rate environment, interest dominates the early years of a loan: at 7% versus 3%, a far larger share of each payment services debt rather than equity.

The common belief: Clearing mortgage debt as fast as possible is always the optimal financial move.

What the data shows: The guaranteed return from prepaying equals the loan rate. A borrower who locked in around 3% during 2020-2021 faces a very different trade-off from one borrowing above 7% in 2023, because the bar a competing investment must clear differs by several percentage points. The arithmetic depends on the rate, the horizon and the tax treatment, not on a universal rule.

The common belief: Housing becomes affordable when prices fall and unaffordable when they rise.

What the data shows: Affordability is a function of prices, mortgage rates and incomes together. Between 2021 and 2023, the monthly payment on a given loan amount rose far more than prices, because higher rates inflated financing costs. Mortgage capacity contracts mechanically as rates climb, so affordability can deteriorate even when prices are flat.

The common belief: A mortgage is a mortgage; the 30-year fixed is a normal product like any other.

What the data shows: The 30-year fixed-rate mortgage is a near-unique U.S. feature, made possible by agency guarantees (Fannie Mae, Freddie Mac) and mortgage-backed securitisation. It transmits monetary policy differently: existing borrowers are insulated from rate increases, unlike variable-rate markets such as the United Kingdom, Australia and parts of Europe, where higher rates pass quickly into household budgets.

The common belief: Housing is a lagging sector that confirms a downturn only once it has already begun.

What the data shows: Housing starts are among the most leading indicators of the cycle. Edward Leamer (2007) documented that residential investment turns down ahead of most U.S. recessions, because the decision to build is highly sensitive to financing costs. When rates rise, construction reacts quickly – well before consumption or employment register the shift.

The common belief: When mortgage rates rise, home prices fall mechanically as buyers can afford less.

What the data shows: The 2022-2023 increase froze supply before it deflated prices. At the mid-2022 peak, around 93% of U.S. mortgage holders had a rate below 6% (Redfin analysis of FHFA data); locked in, they stopped listing. The FHFA estimated the lock-in effect prevented roughly 1.72 million home sales between 2022 and 2024, and existing-home sales fell about 25% versus 2019. Scarcer supply supported nominal prices even as transactions collapsed – the clearest example of why price intuition fails for housing.

The common belief: Wall Street firms bought up the housing stock and drove the surge in prices.

What the data shows: Institutional investors own roughly 2-3% of the U.S. single-family rental stock and less than 0.5% of the total single-family housing stock (GAO 2024; Urban Institute). Their presence is concentrated in a few southeastern metros – about 25% of single-family rentals in Atlanta, 21% in Jacksonville – but nationally marginal. The price surge owes far more to a structural shortage of supply than to institutional buying.

The common belief: Renting is throwing money away; buying always wins financially.

What the data shows: The price-to-rent ratio is a valuation metric: when it stretches well above its historical average, buying is expensive relative to renting. Robert Shiller popularised it as a signal of over- or under-valuation. The buy-versus-rent decision depends on that ratio, the holding period and transaction costs – not on the assumption that ownership is unconditionally superior.

The common belief: Commercial property is a niche that poses no systemic risk to the broader economy.

What the data shows: U.S. banks hold around $2.7 trillion in commercial real estate (CRE) loans, close to a quarter of the average bank’s assets (Federal Reserve, 2024). Exposure is highly asymmetric: CRE makes up roughly 38% of the loan book at small regional banks (under $10bn in assets) versus about 12-13% at the largest banks (S&P Global, 2024). A wall of refinancings at higher rates concentrates the risk on regional lenders.

The common belief: Listed real estate trusts mechanically protect against inflation.

What the data shows: REIT behaviour depends on the sub-sector (offices versus logistics, residential or data centres) and on the real-rate regime. Over short horizons, listed REITs trade more like equities and are sensitive to rising real yields; only over long horizons do they behave like physical property. In 2022, higher real rates weighed on most listed REITs despite elevated inflation – the hedge is conditional, not automatic.

The common belief: Office vacancies are a problem for landlords alone.

What the data shows: The U.S. office vacancy rate reached a record near 20% in 2024-2025 (Moody’s Analytics), surpassing the prior peaks of 1986 and 1991. The consequences spill beyond owners: lower municipal property-tax receipts, pressure on exposed regional banks, and weaker downtown retail. The value of obsolete buildings can fall sharply at refinancing, transmitting stress into the local economy and the banking system.
