Using Survey Findings Strategically

Renegotiate Purchase Price

Survey findings provide evidence-based negotiating power. We've helped clients achieve:

How to negotiate:

  1. Calculate total repair costs from survey
  2. Add 10-20% for contingency and inconvenience
  3. Present findings professionally to seller's agent
  4. Be prepared to walk away if seller won't negotiate

Request Seller Repairs

For urgent issues (leaking roofs, failed drainage), request sellers complete repairs before completion. Ensure:

Budget and Proceed

For desirable properties with manageable issues, budget appropriately and proceed. Survey findings help you:

Walk Away

Sometimes survey findings reveal problems too severe or costly. Walking away is legitimate - better to lose survey fees than buy a problem property.

Timing Your Survey

Common Pre-Purchase Questions

Can I rely on the seller's survey?

No. Seller surveys are commissioned by them, potentially outdated, and don't create duty of care to you. Always commission your own survey.

What if I'm buying at auction?

Survey BEFORE the auction - you exchange immediately when hammer falls. No survey, no protection.

Should I attend the survey?

We don't encourage attendance during inspection, but we're happy to call immediately after to discuss initial findings.

What if the property seems perfect?

Appearances deceive. We regularly find significant defects in "immaculate" properties hidden by cosmetic improvements.
