When to walk away after a home inspection
Walk when a finding's cost is both large and unknown before your deadline, or the seller won't move on a known cost you can't absorb.

What makes a finding a reason to walk away?
A finding is a reason to walk when two things are both true: the cost is large, and no one can put a real number on it before your deadline. It is also a reason to walk when the cost is known and large, and the seller won't move on it. A finding that is neither is priceable, and once priced, negotiable: see what to ask for after a home inspection for what a priced, negotiable finding turns into.
What are the two questions to ask about every finding?
Run every finding, not just the scary-sounding ones, through two questions.
How big? Would the fix cost more than you can absorb on top of what you've already spent on the down payment and moving. A cracked slab tile is not big. A foundation that has moved is.
How knowable? Can a specific professional name a real number before your window closes, or does it require weeks of monitoring, opening walls, or a scope no one can complete in time. A structural engineer can inspect the foundation and give you a written opinion and a repair scope.
A finding only earns a walk-away conversation when it scores high on both. High cost with a knowable number is a negotiation. Low cost with total uncertainty is a nothing burger with an asterisk, not a deal breaker.
What is the biggest red flag in a home inspection?
There isn't one fixed answer, and that's deliberate. "Biggest red flag" is really shorthand for "fails both questions": large cost, no fast way to know the number. Foundation movement gets called this when it fails both. A foundation crack a structural engineer confirms is old, stable, and cosmetic stops being a red flag: it becomes a documented, priced line item. See a foundation crack on your inspection report. A fixed list of scary-sounding findings just moves the guesswork one step earlier. The two questions are the actual test.
Which findings are deal-breakers and which are negotiable?
Here is how seven common finding types score on uncertainty, who can resolve that uncertainty, and whether a desk estimate (a number built from the report alone, no site visit) is enough to act on.
| Finding type | What makes it uncertain | Who can remove the uncertainty | Is a desk estimate enough? |
|---|---|---|---|
| Foundation movement (new cracks, doors that stick, out-of-level floors) | Whether movement is active or historic, and what's causing it | A structural engineer. InterNACHI's own Standards of Practice say inspectors are "not required to... report on the adequacy of any structural system or component" | No. Scope depends on the engineer's finding, not the crack's appearance |
| Roof at or near the end of its rated life | Whether the covering has years left or needs full replacement, and whether the decking underneath is sound | A roofer's on-roof inspection | Sometimes. A stated, limited repair can be desk-priced; a full tear-off can't, because decking condition isn't visible in report photos |
| Old electrical panel brands the report flags | Whether your specific panel is the flagged model and how it's performing today, not its reputation | A licensed electrician who opens the panel | Often yes for the swap itself, once the electrician confirms the model and condition |
| Sewer line defects (root intrusion, a bellied or collapsed pipe) | Whether the fix is a spot repair or a full trenchless replacement, which a report can't show from the surface | A licensed plumber running a camera sewer scope | No. The camera scope sets the actual scope of the fix |
| Moisture and mold | Whether moisture is active or past, and what's causing it: grading, a leak, or ventilation | Moisture meter readings and fixing the source; a certified mold assessor if testing is warranted | No, not until the source is identified. Pricing "remove mold" with no known cause prices a guess |
| Aged HVAC systems | Whether the system has useful life left, or needs replacement this season | An HVAC contractor's system inspection and load calculation | Sometimes. A repair (a capacitor, a refrigerant top-off) is desk-priceable; a full system swap isn't |
| A long list of small items (a loose handrail, a missing GFCI, worn caulking) | Nothing, individually. The only uncertainty is the total | No single professional; add up the list | Yes. This is exactly the case a desk estimate is built for |
On old panel brands specifically: the Consumer Product Safety Commission investigated Federal Pacific Electric Stab-Lok breakers for two years and closed the case saying the data available "does not establish that the circuit breakers pose a serious risk of injury," and did not order a recall (CPSC, originally issued 1983, revised 2011). That is the actual government finding, not "these panels are illegal" or "these will burn your house down." What matters for your decision is what an electrician finds when they open your panel, not the brand's reputation online.
What if the cost is known and the seller won't move?
Walking is also on the table when the cost is priced, confirmed, and too big for you to absorb, and the seller offers no credit, no fix, and no price drop to cover it. Here is what a priced, known cost actually looks like, so "priced" isn't an abstraction:
These are Kept's modeled estimates from public wage and materials data, not quotes.
| Example finding | Cost | Source |
|---|---|---|
| Replace about 140 sq ft of cracked, lifted asphalt shingles on one roof slope | $1,439 | usekept.com sample memo |
At that point you're choosing between paying it yourself, walking, or renegotiating the price, the same choice you'd face with a known cost from any source. A priced, itemized ask is what gets a response; a round number with no backup is easy for a seller to wave off as a wish list.
Why should I price the whole report before deciding?
A long report lists everything the inspector saw, not just what's expensive. Price every line first, then look at the total: a report with many findings and a modest total isn't the same decision as a report with few findings and the same total, but they read identically until priced. Pricing the whole list is what turns "should we walk" from a feeling into a number you can weigh against the house. Every way to get that number before your window closes is covered in how to get repair estimates during the inspection period.
How do I know which words in the report actually matter?
Before you can run the two-question test, you need to know which words in the report mean "serious" and which mean "normal for a house this age." That section-by-section triage is covered in how to read a home inspection report.
What about my deadline to walk away?
Your contract sets this. Ask your agent or attorney for the date and the rule in your state.
If you're inside your window and want the whole report priced before you decide, Kept turns your inspection report into an itemized repair-cost memo, usually under 4 hours.
