Transaction Friction and the Break-Even Horizon

Real estate is a high-friction market, engineered to bleed capital on the way in and again on the way out. Buying and later selling a home incurs round-trip transaction costs that typically land near 8% to 10% of the property’s value: agent commissions, closing costs, transfer and recording taxes, title insurance, and assorted fees. Since the 2024 National Association of Realtors antitrust settlement, commissions are more openly negotiable than they once were — but in practice the round trip still lands in that range.

The implication is stark. Buy a $2,000,000 home and you are instantly underwater by roughly $160,000 in pure friction. Before you have earned a cent, the property must appreciate by that margin just to let you exit at break-even. Let V i be the purchase price and ctx the round-trip transaction-cost rate; the sale price V f needed merely to recover the transaction itself is:

V f = V i × (1 + ctx)

and that ignores every carrying cost in Ch accumulating along the way.

This is the real reason for the familiar holding-period guidance. Clearing transaction friction alone takes, at typical appreciation rates, something like five to seven years; clearing friction plus the accumulated unrecoverable carrying costs is what pushes full break-even into the five-to-ten-year range discussed in section “The NPV Framework: A Rigorous Buy-vs-Rent Comparison”. The corollary: if there is genuine uncertainty about your job, your city, or your relationships over that horizon, buying is an asymmetric bet tilted against you. Renting, for all its supposed indignity, buys you a valuable option — the option to leave cheaply.
