Home Walkthrough Checklist: 10 Essential Things to Inspect Before Buying

During a home walkthrough, observing condition, safety, and function helps reduce surprises after purchase. This guide lists the top 10 things to look for during a home walkthrough and explains practical checks that inform decisions and conversations with sellers or a licensed home inspector.

Home walkthrough: 10 key areas to inspect

1. Exterior and roof

Look for missing, cracked, or curling shingles; sagging rooflines; and signs of recent patching. Inspect gutters and downspouts for clogs or improper discharge. Check siding, brickwork, and trim for rot, cracks, or separation from the foundation. These items can indicate roof or water management issues.

2. Foundation and grading

Scan the foundation for visible cracks, bowing, or gaps at the exterior. Verify that landscape grading directs water away from the house and that window wells and patios do not trap water against the foundation. Persistent dampness or pooling near the foundation increases the risk of basement leaks.

3. Windows, doors, and insulation

Open and close windows and doors to test fit and function. Check for broken seals, fogging double panes, and missing weatherstripping. Look in attics and basements for insulation levels and ventilation. Proper sealing and insulation affect comfort and energy costs.

4. Plumbing

Run faucets, flush toilets, and check under sinks for leaks or corrosion. Observe water pressure and temperature consistency at multiple fixtures. Inspect visible pipes for rust or signs of past repairs; note the type of piping (copper, PVC, PEX). Standing water or poor drainage in drains or gutters is a red flag.

5. Electrical system

Test lights, switches, and outlets in each room. Open the electrical panel to confirm labeled breakers and note any double-tapped breakers or missing panel covers. Check for modern GFCI outlets in kitchens, bathrooms, and exterior locations. Exposed wiring or frequent blown fuses should prompt a professional evaluation.

6. Heating, ventilation, and air conditioning (HVAC)

Operate the heating and cooling systems to confirm they start, run smoothly, and produce expected temperatures. Check service records if available and look at the age and condition of units. Inspect visible ductwork for damage and ensure vents are present and unobstructed.

7. Appliances and systems

Test included appliances (stove, oven, dishwasher, washer/dryer) and the water heater. Note unusual noises, leaks, or signs of deferred maintenance. Determine whether appliances stay with the property and whether warranties or manuals are available.

8. Interior condition and finishes

Walk every room checking floors, walls, ceilings, and trim. Look for cracks, uneven floors, stains (which may indicate leaks), or odours suggesting mold or infestations. Check closets, cabinets, and basement or crawlspace access points for hidden issues.

9. Safety and code-related items

Confirm functioning smoke and carbon monoxide detectors. Inspect stair railings, exterior steps, handrails, and pool or deck safety features. Be alert to large-scale modifications that may be unpermitted (added rooms, structural changes). Local building departments or a licensed inspector can verify permits and code compliance.

10. Pest and environmental concerns

Look for signs of termites, rodents, or insects—mud tubes, chewed wood, droppings, or nesting. Check for mold, musty odors, and water stains. For known environmental hazards (lead paint in older homes, radon), consider specialist testing; authoritative guidance is available from federal agencies and local health departments.

Preparing for a walkthrough and documenting findings

Bring tools and take notes

Bring a basic checklist, a flashlight, a notepad or mobile device for photos, and a tape measure. Photograph items of concern and time-stamp images when possible. Record locations, descriptions, and whether the issue is cosmetic or functional.

Follow-up steps

For significant concerns, request repairs, price adjustments, or stipulations in the sales contract. Arrange a professional home inspection performed by a licensed inspector for a detailed evaluation; organizations such as the American Society of Home Inspectors (ASHI) provide directories of certified inspectors. For permit verification or code questions, contact the local building department.

For general homebuying guidance from a government source, see the U.S. Department of Housing and Urban Development's buyer resources (HUD: Buying a Home).

When to call a professional

Structural, electrical, or major system concerns

Items such as foundation settlement, major roof issues, electrical hazards, or significant plumbing or HVAC problems warrant specialist evaluation. Licensed contractors, structural engineers, or certified inspectors can provide estimates and repair scopes to inform negotiations.

Minor issues and cosmetic items

Cosmetic defects—peeling paint, scuffs, or minor trim damage—are typically lower priority in negotiations but should still be noted if they affect habitability or indicate deeper problems.

Frequently asked questions

What should be included in a home walkthrough?

A typical home walkthrough includes a visual inspection of the roof, foundation, exterior, plumbing, electrical, HVAC, appliances, interior finishes, and safety systems. Document issues with photos and notes, and follow up with a licensed home inspector for a detailed report.

How long does a home walkthrough usually take?

Walkthroughs at showings may take 15–45 minutes, while final walk-throughs before closing often take 30–60 minutes depending on property size and observed issues. Allow extra time if testing systems or reviewing repairs.

Is a home walkthrough the same as a home inspection?

No. A walkthrough is a buyer or agent-led visual check, often brief. A home inspection is a formal, paid evaluation by a licensed inspector who performs detailed tests and provides a written report. A professional inspection should complement the walkthrough.

What are common red flags found during walkthroughs?

Common red flags include active water leaks, electrical hazards, unpermitted additions, significant foundation cracks, roof damage, mold, pest infestations, and evidence of deferred maintenance. Any of these should prompt further professional evaluation.

Can repairs always be negotiated after a walkthrough?

Repairs can often be negotiated, but outcomes depend on the contract, market conditions, and seller willingness. Obtain contractor estimates or inspection reports to support repair requests and consider contingency clauses in the purchase agreement.
