The honest truth: most home inspection findings are negotiable, not deal-breakers. But some findings really are reasons to walk away. Here's exactly what an InterNACHI Master Certified inspector considers a true deal-breaker on Apple Valley and Dakota County homes — and what's just expensive but workable.

1. Active foundation movement
Static foundation cracks from past settlement are negotiable. Active movement — cracks that are growing, walls that have visibly bowed in the last few years, doors and windows that won't close properly because the home is shifting — is a different problem entirely. Repair can run $30K-$100K+ and even after fix, resale is permanently impacted.
2. Severe roof failure with sheathing damage
A worn-out roof needing replacement: $12K-$25K. Negotiable. A roof that's leaked for years and rotted the sheathing underneath: $25K-$60K, plus interior repairs, plus potential mold remediation. The compounding makes this dangerous.
3. Multiple major systems near end-of-life simultaneously
One failing system is negotiable. Three at once is a different equation:
- Roof = $15K replacement
- HVAC = $10K replacement
- Water heater = $1.5K replacement
- Electrical panel = $4K replacement
- Cedar siding rot = $25K re-side
That's $55K of immediate post-closing capital. Even with full seller credit, you're managing 5 contractors in your first 6 months. Walk unless the home is exceptional.
4. Hidden water damage with mold potential you can't quantify
Visible localized water damage = negotiable. Hidden water damage where the inspector finds moisture but can't determine extent (behind walls, under floors, in concealed cavities) = unknowable cost. Mold remediation alone can be $5K-$30K+, and that's before structural repairs.
5. Buried oil tanks (1970s-and-earlier homes)
Older homes occasionally heated with oil. The buried tanks were often abandoned in place when homes converted to gas. If those tanks leaked, soil contamination becomes the new owner's liability — potentially $20K-$200K+ in remediation. Always investigate suspicious fill pipes or vent stubs.
6. Seller refuses ANY negotiation on legitimate safety items
This is more about the seller than the home. If active gas leaks, exposed electrical, or imminent structural risk are present and the seller won't credit or repair them, that's a red flag about who you're dealing with. Walk and don't look back.
7. Undisclosed material defects you can prove
Minnesota requires sellers to disclose known material defects. If your inspector finds something the seller obviously knew about (fresh paint covering active leaks, repair receipts in the basement, neighbor confirming past issues) and the seller stayed silent, you have legal grounds to walk AND potentially recover damages. Document everything; consult a real estate attorney.

Free Instant Estimate →What's NOT a deal-breaker (just expensive)
Old furnace and A/C
End-of-life HVAC is annoying but predictable. $8K-$15K to replace both. Negotiate a credit and budget the replacement.
Single-system roof needing replacement
Old roof is a known cost: $12K-$25K. Negotiate it. Move on.
Aluminum branch wiring
Sounds scary; fix is $3K-$6K with COPALUM connectors. Common in 1970s Burnsville/Eagan. Just negotiate. Full guide.
Cedar siding rot (cosmetic to moderate)
Spot repair: $1K-$5K. Section replacement: $5K-$15K. Full re-side: $25K-$45K but recoverable in resale. Full guide.
Failed window seals
Foggy double-pane windows. $300-$600 per window. Negotiate or replace gradually.
Radon over EPA action level
Mitigation system: $1,200-$2,000. Standard negotiation point in Dakota County. Almost expected. Full guide.
Knob-and-tube wiring (in older homes)
Insurance issue but not necessarily a deal-killer. Get an electrician's estimate for partial or full replacement. Negotiate or factor into your budget.
The math: when does the cost make it a bad deal?
Rough rule of thumb: add up immediate repair costs + 5-year capital expenses. If that total exceeds 8-10% of the contract price AND the seller won't negotiate, the math probably doesn't work.
On a $400,000 Apple Valley home, that's $32K-$40K in projected repairs. If you're seeing more than that and seller won't credit/repair, walk.
The 4-step deal-breaker decision framework
- Categorize — separate true safety/structural items from "expensive but workable"
- Quantify — get contractor estimates on the major items
- Negotiate — submit a focused inspection objection letter
- Decide — if final post-negotiation cost is acceptable, proceed; if not, walk while you're still in inspection contingency
What "walking" actually looks like
If you decide to walk during the inspection contingency window:
- Notify the seller in writing through your agent
- Cite the inspection contingency clause in the purchase agreement
- Your earnest money returns to you (not forfeited)
- You're done — find a new home
Walking is not a failure. The home will still exist. Other homes exist. Your earnest money is intact. Your sanity is intact.
