Buying
Home inspection checklist
This page explains what a home inspection can and cannot tell you, and how to direct it at the systems that carry real cost.
An inspector is a generalist working visually for a few hours. The value is in knowing which of the dozens of noted items are five-figure problems and which are ordinary maintenance.
- What this is
- A buyer's guide to getting real value from an inspection.
- Who it is for
- Buyers under contract, and anyone deciding whether to waive an inspection.
- The problem
- Inspection reports are long and undifferentiated. Buyers finish them without knowing which findings matter financially.
- What happens next
- Price the significant findings into your offer, or request the maintenance and service records before renegotiating.
The five systems that carry the cost
Roof, heating and cooling, electrical service and panel, plumbing supply and drainage, and structure or foundation. Nearly all expensive surprises live in these five.
For each, you want approximate age, evidence of past repair, and remaining useful life. A twenty-two-year-old roof is not a defect; it is a budget item with a date on it.
What a standard inspection excludes
Inside walls, under the slab, buried tanks, most chimneys beyond a visual check, and anything obstructed by storage or snow. Sewer lines, wells, septic systems, radon, mold, pests and pools are usually separate specialists.
On rural or older property, budget for the specialists rather than assuming the general inspection covered them.
Recently renovated homes need different attention
A cosmetic renovation can conceal deferred maintenance behind new finishes. Ask which work was permitted, request the permit history and final inspections, and pay attention to whether mechanical systems were updated alongside the kitchen.
New paint over an old electrical panel is a common pattern, and one an inspector will note flatly rather than emphatically.
Turning findings into a number
Sort every finding into three buckets: safety, near-term replacement within five years, and ordinary maintenance. Negotiate on the first two, and expect to absorb the third.
Ask for costs from a contractor rather than from the inspector. Sellers respond to quotes, not to adjectives.

Should I ever waive a home inspection?
Waiving the contingency in a competitive market is a financial decision, not a formality. If you do, get a pre-offer walkthrough with a contractor and set aside a reserve for what you could not see.
How much does a home inspection cost?
Commonly $400 to $800 for a single-family home, more for large or rural properties, with sewer scope, radon and septic inspections priced separately.
What are the most expensive inspection findings?
Foundation movement, full roof replacement, sewer line failure, knob-and-tube or aluminum branch wiring, and failed septic systems. These are the findings that justify renegotiating.
Can I renegotiate after inspection?
Usually yes, if your contract includes an inspection contingency. The strongest requests are specific, supported by contractor quotes, and limited to safety and near-term replacement items.
How long is an inspection report valid?
It describes the property on one day. Findings do not expire quickly, but if months pass or a season changes, conditions like drainage and roof performance may have changed.
Should I attend the inspection?
Yes, at least for the final walkthrough of findings. Ten minutes with the inspector in the basement is worth more than the written report.
