The Property Walkthrough Checklist

Professional home inspectors evaluate 50–100 distinct systems and components in 3–4 hours. A casual walk misses 90% of them. The walkthrough checklist is the difference between spotting a foundation crack and discovering it after you've already closed.

Key takeaways

• A professional inspection costs $400–$800 but routinely uncovers $2,000–$10,000 in hidden repairs that casual buyers miss. Never skip it.
• Structural systems (foundation, roof, HVAC, plumbing, electrical) dominate the cost of repairs. They are your first priority; cosmetics are last.
• Wear proper clothes to inspections: old shoes, long pants, gloves. You will be in crawl spaces, attics, and basements.
• The inspector's report is not a pass/fail; it's a priority list. Your job is to understand what's critical (safety, structural) vs. cosmetic (paint, flooring).
• Hire your own inspector, not the seller's or the lender's inspector. You need an advocate, not a checkbox.

The systematic walk

Professional inspectors follow a sequence. You should too.

Exterior and site

1. Roof condition and age. Walk around the property and look up. Shingles should be flat and uniformly colored. Curled, missing, or buckling shingles mean replacement is near. A roof typically lasts 15–20 years. If it's 18+ years old, budget for replacement in 2–3 years ($8,000–$12,000 for a standard single-family). If you see blue tarps or recent patches, ask when and what was repaired.

2. Gutters and downspouts. Standing water in gutters, sagging sections, or missing downspouts are minor fixes ($500–$1,500) but indicate whether the owner has maintained the property.

3. Chimney condition. Cracks in mortar, missing bricks, or a leaning chimney are red flags. Chimney repair is $1,500–$3,000 per section.

4. Grading and drainage. Walk the perimeter. Water should slope away from the house. If water pools near the foundation or the ground slopes toward the house, you have drainage issues that can lead to foundation cracks and basement water intrusion.

5. Visible foundation cracks. Small hairline cracks (<1/8 inch) are normal in concrete and masonry. Wider cracks, cracks that follow mortar lines unevenly, or cracks combined with wall bowing suggest settlement or structural issues. Budget $3,000–$8,000 for foundation repair if it's serious.

6. Deck or porch condition. Check for rotted wood, loose boards, or missing railings. Deck replacement is $3,000–$5,000 per 12x12 ft. If the deck is soft underfoot, wood rot is advanced.

7. Exterior paint and siding. Peeling paint suggests old paint (possibly lead in homes built before 1978—get a lead test for $300–$500 if you have tenants with kids). Rotted siding requires replacement. Vinyl or fiber cement siding lasts 20–40 years; wood lasts 5–15.

8. Gravel, fencing, and landscaping. These are cosmetic in the inspection sense but matter to tenants. A fence in disrepair is a $2,000–$4,000 fix.

Entry and doors

9. Exterior doors and hardware. Are doors level? Do they open smoothly? Warped or stuck doors suggest settling or moisture. Broken locks or hinges are cheap fixes.

10. Entryway flooring. Look for water stains, soft spots, or signs of previous water intrusion.

Interior structural and systems

11. Attic condition. Walk the attic (if accessible). Look for:

    • Roof leaks (dark stains on decking or rafters).
    • Proper ventilation (no moisture or mold).
    • Insulation depth and type (older homes often have inadequate insulation).
    • Sagging roof decking (suggests structural issues or excessive snow load history).

12. Basement or crawl space. This is where water damage and structural problems hide:

    • Water stains on walls or beams (previous or ongoing flooding).
    • Cracks in concrete floor or foundation walls.
    • Mold or musty smell (indicates moisture, not necessarily active).
    • Sagging or soft floor joists (structural concern).
    • Efflorescence (white powder on concrete—indicates water movement through masonry).
    • Proper grading around the perimeter (water should slope away from house).

13. HVAC system (furnace/boiler). Check the age from the nameplate. Furnaces typically last 15–20 years, heat pumps 10–15. A unit over 15 years is worth budgeting replacement for ($4,000–$6,000 installed). Ask for maintenance records; well-maintained systems last longer.

14. Air conditioning condensing unit (if present). Is it accessible? Is the fin coil bent (reduces efficiency)? Age it from the nameplate. Replace at 15–20 years ($3,000–$5,000 for a basic unit).

15. Water heater. Check the nameplate for age. Water heaters typically last 10–15 years. If it's 12+ years old, expect replacement soon ($1,200–$2,000 installed). Look for rust or leaks around the base.

16. Electrical panel. Is it a breaker panel or an older fuse panel? Fuse panels should be upgraded ($2,000–$4,000). Are the breakers labeled? Do they trip easily when reset, or do they stick? A sticky breaker or burning smell near the panel is a red flag.

17. Electrical outlets and switches. Are there two-prong (ungrounded) outlets in bedrooms or living areas? Old two-prong outlets suggest older wiring that may not be safe for modern appliance loads. Upgrading a full circuit is $1,500–$2,500. Check that outlets work (bring a tester). Missing outlet covers are cosmetic.

18. Plumbing entry point. Where do water lines enter the house? Are they copper, PEX, galvanized steel, or PVC? Galvanized steel corrodes over time; if you see greenish corrosion on fittings, water pressure may be reduced and leaks may be coming. Replacing galvanized plumbing costs $3,000–$8,000 depending on the extent.

19. Visible plumbing. Check under sinks for leaks. Are pipes corroded, dripping, or soft (indicating pinhole leaks)? Small leaks are cheap; systemic pinhole leaks in copper are expensive.

Rooms and spaces

20. Ceilings for water stains. Yellow or dark brown stains indicate roof leaks or water intrusion from above. Check the attic directly above any stain.

21. Walls for cracks. Small settlement cracks (diagonal, especially at corners or near doors) are common and cosmetic. Horizontal cracks or cracks wider than 1/4 inch suggest structural or moisture issues.

22. Flooring condition. Walk on hardwood, tile, and carpet. Soft spots in hardwood indicate rot (water damage). Cracked tile suggests movement underneath. Worn carpet is cosmetic but may hide damage below.

23. Window operation and seals. Open and close every window. Do they stick? Is the glass fogged (broken seal, condensation trapped between panes—$300–$500 to replace the sash or unit)? Are frames rotting or painted shut?

24. Bathroom plumbing fixtures. Do faucets run (even a slow drip wastes water)? Do toilets have a slow leak (add food coloring to the tank; if it shows in the bowl without flushing, there's a leak)? Does the shower drain properly or is there standing water?

25. Bathroom exhaust ventilation. Is there a bathroom fan? Does it pull (test by holding tissue near the vent cover)? Improper ventilation leads to mold.

26. Kitchen appliances. Are they original to the home (age indicator)? Do they work? If the home is being sold as furnished with appliances, confirm age and condition. Appliance replacement is $300–$1,000 each.

27. Counters and cabinets. Water damage under sinks? Soft or warped cabinet bottoms? These are cheap fixes but indicate moisture issues.

Exterior final checks

28. Grading and standing water. Walk the full perimeter after checking the interior. Water puddling near the foundation is a chronic issue.

29. Downspout discharge. Do downspouts run water away from the house or into the foundation? They should extend 5–10 feet away or into a proper drainage system.

30. Neighbor properties. Walk by the neighboring homes. Are they well-maintained? Occupied? Abandoned homes nearby suggest a neighborhood decline risk.

The cost-priority matrix

After the inspection, categorize findings:

Critical (deal-breaking):

• Foundation failure or active settling (homes sliding, cracks widening).
• Roof leaks ongoing.
• Electrical hazards (burning smell, live exposed wires).
• Plumbing failures (no water pressure, sewage backups).
• Mold in HVAC system or structural wood.

Important (budget now):

• Furnace/boiler over 15 years old.
• Roof over 18 years (replace within 2–3 years).
• Water heater over 12 years.
• Major structural cracks (foundation, walls, floor joists).
• Galvanized or corroded plumbing.
• Fuse panel (upgrade to breaker).

Nice-to-have (budget in future years):

• Worn carpet or flooring.
• Exterior paint or minor siding damage.
• Window seals (fogged glass).
• Cosmetic kitchen or bathroom updates.

Critical issues are deal-killers. Important issues get negotiated off the price or into repair allowances. Nice-to-haves are part of your 5-year capital plan.

The negotiation play

Once you have the inspection report, you have three options:

1. Ask the seller to repair. Works only if the repair is straightforward (replace water heater, repair gutter) and the seller is motivated. For structural or costly items, sellers usually say no.

2. Ask for a price reduction. Request $100–$200 per $1,000 of estimated repair cost (conservative). If the roof needs $10,000 in replacement, ask for a $10,000–$15,000 price reduction. Sellers often negotiate here because it reduces their liability.

3. Proceed as-is but budget conservatively. You account for repairs in your cash-flow model and factor them into your offer price before negotiating. This is the safest approach for rentals.

Seasonal considerations

• Winter inspections miss roof leaks that show when snow melts or ice dams form. If you inspect in winter, plan for a spring re-inspection or budget $2,000 for potential roof repairs.

• Summer inspections don't reveal heating system problems. Request the heating system be turned on briefly so you can verify it works.

• Dry season inspection hides drainage issues. Ask how the property handles heavy rain and look for any water damage in the basement.

What you'll actually find

On a typical 1970–1990s single-family home in a B-market, expect:

• Minor cosmetic issues (paint, flooring, fixtures)—not a deal concern.
• One major item (roof, furnace, or water heater nearing end of life)—budget $4,000–$8,000.
• Multiple small issues (a leaky faucet, a loose shingle, a stuck window)—$500–$2,000 total.

If the home is well-maintained (original owner, renovation in the past 10 years), the inspection is cleaner. If the home is a flip or a bank-owned property, expect more surprises and budget accordingly.

Process

Next

The property has passed inspection. Now you need to understand the neighborhood itself—not just the house. Some of the most important factors affecting rent and long-term value have nothing to do with the building and everything to do with where it sits: the school district, the crime rate, the employer base. That's the neighborhood grading system.
