Yes! 23% of homebuyers successfully negotiated lower purchase prices based on survey findings. You can request price reductions to cover repair costs, ask the seller to fix issues, or withdraw from the purchase if problems are too severe.
Do I need a survey for a new-build property?
Absolutely. 95% of new homeowners identified defects after moving in, with a third reporting 16+ issues. New builds can have construction problems, poor workmanship, or snagging issues that an independent survey will identify.
