Buy vs. Rent

The conventional wisdom that buying is always better than renting is one of the most persistent and consequential misconceptions in personal finance. The actual math depends on price-to-rent ratios, expected holding period, investment return assumptions, transaction costs, and local market dynamics — and in many high-cost markets at various points in the cycle, renting is the financially superior choice for buyers with a holding period under five to seven years.

The price-to-rent ratio is the starting point. Divide a home’s purchase price by its annual rental equivalent — if a $2 million home would rent for $8,000 per month ($96,000 annually), the price-to-rent ratio is approximately 21. Ratios below 15 generally favor buying; ratios above 20 generally favor renting for shorter holding periods. In San Francisco, New York, and Los Angeles, price-to-rent ratios regularly exceed 25–35, which shifts the math meaningfully toward renting even after tax benefits are factored in.

Transaction costs are the buy-side variable that most calculations underweight. Buying costs — agent commissions, title insurance, mortgage origination, closing costs — typically run 3–5% of the purchase price. Selling costs add another 5–6%. Together, round-trip transaction costs on a $2 million home can exceed $200,000. Recovering that cost in appreciation requires either significant price appreciation or a long enough holding period to amortize it — typically five to seven years at normal appreciation rates.

For households who have settled on buying, the next questions live in first home for primary residence decisions, or second homes for vacation property analysis. The opportunity cost logic here also applies to luxury rentals, where the premium rental market sometimes offers flexibility that justifies the premium.
