London sales vary street by street. A Victorian terrace in Hackney, a mansion-block flat in Maida Vale and a semi in Bromley attract different buyers and need different advice, and vendors know it.
Most buyer searching happens on Rightmove, Zoopla and OnTheMarket, so an agent's own site earns its keep on the vendor side: valuations, market commentary and proof of recent sales.
Estate agents must belong to an approved redress scheme, and listings are now expected to carry material information (facts a buyer needs, such as tenure and costs) up front.
Stamp duty changes and mortgage rates move sentiment quickly, so the wording on a valuation page needs updating whenever the market shifts.
