The Flattering Valuation Trap

Glendale & Cheviot · July 2026 · 3-minute read

Three agents value your home. One says a number £25,000 higher than the others. Guess who usually gets the instruction — and guess what happens next.

Overvaluing to win instructions is one of the oldest plays in the book, and "you can always come down" is its accomplice. The problem: your listing's most valuable weeks are its first ones. Portal algorithms and buyers' alerts light up for new stock; an overpriced launch burns that attention on a price that was never going to sell. By the time the "planned" reduction arrives, the listing is stale, buyers wonder what's wrong with it, and the eventual sale price is frequently lower than an honest launch would have achieved.

Why the incentive exists

For a commission-based agent, an instruction on the books is worth winning even if it sells late and low — the commission difference on £10,000 of sale price is small change to them but not to you. A fixed fee removes that game entirely: we earn the same either way, so the only sensible thing left to do is tell you the truth.

How to protect yourself

• Ask every valuing agent for the comparable sold prices behind their number — not asking prices, sold prices.
• Be suspicious of an outlier that comes bundled with a long tie-in period.
• Watch the first three weeks' data like a hawk — and work with an agent who shows it to you weekly.
