Overpaying usually starts with skipping research, not with a single bad decision at the negotiating table. Before you make an offer, build a clear picture of recent comparable sales so you know the realistic range for that property, rather than relying on the price guide alone.
Decide on your maximum figure in advance and write it down somewhere you will actually look at it during negotiations. Buyers who set a ceiling before they fall in love with a property are far less likely to get caught up bidding against themselves when an agent reports interest from another party.
Factor in the cost of any work the property needs before you compare it to other homes on price alone. A property that looks cheaper on paper can end up costing more once you add a new roof, rewiring or an outdated kitchen into the equation.
Avoid the trap of assuming every counter-offer must be met. A seller countering your offer is simply testing where you sit, and a firm, well-reasoned response often brings the price back down closer to fair value than an immediate concession would.
If the numbers no longer make sense once all the costs are in, be willing to walk away. There will always be another property, but there is no way to undo paying too much once settlement has happened.
Happy to talk it through — no pressure, no sales pitch.
