Negotiation Tips
Tip
Why
Focus on health/safety and structural issues
Sellers most likely to agree
Ask for credits (not repairs)
You control the contractor and quality
Don’t nickel-and-dime on cosmetic items
Annoys seller, risks entire deal
Get contractor estimates for major issues
Stronger negotiation position
Prioritize: pick your top 3-5 concerns
More effective than a 30-item list
Know your market: in seller’s markets, expect less
More leverage in buyer’s markets
When to Skip or Waive Inspection
Situation
Skip Inspection?
Risk Level
Highly competitive market (multiple offers)
Some buyers waive
HIGH — could miss $10K-$50K issues
New construction (builder warranty)
Sometimes skipped
MEDIUM — still recommended
Investment/flip property (priced for condition)
Sometimes skipped
MEDIUM — factor repairs into offer
Any home you’ll live in
Never skip
—
Our advice: Never waive a home inspection. Even in competitive markets, consider an “informational” inspection (you pay for it but won’t ask for repairs) that lets you discover major issues before committing.
