Home Tour Checklist: 40 Things to Look for Before Making an Offer

A home tour is not just looking.

Most first-time buyers walk through a property thinking about furniture placement and paint colors. Buyers who've been through the process before — or who've been burned once — walk through doing something entirely different: a preliminary inspection.

You won't catch everything a licensed home inspector catches. That's not the goal. The goal is to gather enough information to decide whether a property is worth spending $500–$700 on a full inspection — and to flag anything serious before you get emotionally attached.

Here are 40 things to check before you make an offer.

Before You Walk In: The Exterior

You learn a lot about a home before you open the front door.

1. Roofline. From the driveway, look at the roofline. Is it straight, or does it sag in the middle? Sagging indicates structural issues. Check visible shingles — missing, curling, or granule loss signals the roof is nearing end of life. A new roof costs $8,000–$20,000+ depending on size and material. 2. Gutters. Are they firmly attached, or pulling away from the fascia? Clogged or damaged gutters send water toward the foundation — one of the most expensive repair categories in residential real estate. 3. Foundation. Walk the full perimeter. Horizontal cracks in the foundation wall are serious (lateral pressure, potential structural failure). Stair-step cracks in brick veneer indicate settlement. Small hairline vertical cracks are usually normal. Note anything wider than a credit card for the inspector. 4. Grading. Does the land slope away from the house, or toward it? Water that drains toward the foundation causes moisture intrusion and long-term structural problems. 5. Driveway and walkways. Severe cracking or heaving indicates shifting soil. Also note as a safety and liability consideration. 6. Siding condition. Look for rot, peeling paint, gaps at seams, or pest damage around window frames and trim. Wood rot spreads behind surfaces — visible damage is often the tip of a larger problem. 7. Windows from the exterior. Are frames square, or racked? Racked window frames indicate uneven settling. Look for rot or peeling paint around the frames.

Kitchen

The kitchen is the most expensive room to renovate — and the most common place for hidden plumbing problems.

8. Cabinet quality. Open and close every cabinet door. Solid wood construction vs. stapled particleboard. Doors that don't hang straight can signal moisture damage or poor construction. 9. Under-sink cabinet. Open it and look at the floor of the cabinet. Water stains, rust, soft spots, or active drips indicate a past or present plumbing leak. 10. Appliance age. Check the stickers on the back or inside of the refrigerator, oven, and dishwasher. Most appliances last 10–15 years. A full kitchen appliance replacement runs $3,000–$8,000. 11. Water pressure. Turn on the kitchen faucet fully. Strong, consistent flow is normal. Weak or irregular pressure can indicate pipe corrosion, pressure regulator issues, or a broader plumbing problem. 12. Counter and tile grout. Cracked or missing grout at the counter-to-backsplash joint allows water to penetrate into the substrate below — leading to mold and structural damage.

Bathrooms

Bathrooms have the highest concentration of water-related issues in any home.

13. Grout and caulk. Run your finger along grout lines and caulk seams in the shower and around the tub. Pink or black discoloration is mold. Missing grout allows water intrusion behind tile — leading to substrate rot that can require a full bathroom demo to fix properly. 14. Flush test. Flush every toilet. It should empty completely and refill without running continuously. A running toilet wastes water and signals a worn flapper or fill valve. 15. Shower and tub drainage. Run the shower or tub and watch the drain. Slow drainage indicates a partial blockage or pipe issue. 16. Ventilation. Bathrooms without proper exhaust ventilation trap moisture and breed mold. Turn on the exhaust fan and hold a piece of toilet paper near the intake — it should hold against the airflow. If the fan is weak or absent, moisture damage is likely. 17. Under-sink inspection. Same check as the kitchen — look for staining, rust, soft flooring inside the cabinet.

Bedrooms

18. Closet depth and layout. Walk into every closet. Are they functional? Closet size is one of the most common post-purchase regrets among first-time buyers. 19. Natural light and window operation. Note which direction each bedroom faces. Check that every window opens, locks, and has a functioning screen. North-facing rooms receive significantly less natural light. 20. Outlet count. Modern bedrooms should have multiple outlets per wall. Older homes often have 1–2 outlets per room — adding more requires electrical work and is often a surprise cost. 21. Noise level. While standing in the bedroom, listen. Highway noise, a busy road, a neighbor's HVAC unit directly outside — these are essentially impossible to fix after purchase. 22. Closet moisture check. Inside ground-floor closets, look for water stains on walls, soft spots on the floor, or a musty smell. These indicate a moisture problem from outside or from below.

Living Areas and Common Spaces

23. Floors. Walk every room slowly and deliberately. Feel for soft spots in hardwood (water damage to the subfloor), bounce or flex in the subfloor (rot or inadequate support), or significant gaps between planks. 24. Wall cracks. Small hairline cracks near door and window corners are typically normal settling. Wide cracks, diagonal cracks across a corner, or horizontal cracks across a wall indicate movement that needs professional evaluation. 25. Ceiling stains. Yellow or brown staining on any ceiling is a water damage signal — from a leaking roof, bathroom above, or ice dam. Even if it looks dry, it means water has been there. 26. Door alignment. Open and close every interior door. Doors that stick, swing open on their own, or won't latch indicate uneven settlement. Normal in very old homes; serious when severe or recent.

Basement and Crawlspace

27. Moisture and water staining. Walk the full basement perimeter. White chalky deposits (efflorescence) on concrete walls indicate water migration. Water stains at floor level indicate past flooding. 28. Smell. Trust your nose. A musty basement smell almost always means moisture, and moisture usually means mold — even if it isn't visible. Mold hidden in walls, insulation, or under flooring can cost $5,000–$30,000+ to remediate properly. 29. Structural cracks in foundation walls. Horizontal cracks in block or poured concrete walls are a red flag — they indicate lateral soil pressure and potential wall failure. Stair-step cracks in block walls indicate differential settling. Have any crack wider than a credit card evaluated by a structural engineer before making an offer.

HVAC and Utilities

30. Furnace age. Find the furnace and look for the manufacture date sticker (usually on the inside panel or near the burner). Furnaces last 15–20 years. An aging furnace is a near-term replacement cost of $3,000–$8,000+. 31. Air conditioning unit. Locate the outdoor condenser unit and check for corrosion on the refrigerant lines, visible damage, and the manufacture date. AC replacement runs $3,000–$7,000+. 32. Water heater. Find the manufacture date on the label. Standard tank water heaters last 8–12 years. Replacement costs $600–$2,000 for conventional tank models. If it's over 10 years old, it's a near-term expense. 33. Electrical panel. Open the panel door. Look for double-tapping (two wires on one breaker — a code violation), aluminum branch circuit wiring (silver-colored wires — fire risk in older homes), or Federal Pacific/Zinsco brand panels (well-documented safety issues, typically flagged by inspectors for replacement). 34. Plumbing type. Ask the listing agent what the visible plumbing is made of. Copper and PEX are both excellent. Galvanized steel (dull gray, pre-1960) corrodes from the inside, reduces water pressure over time, and will need replacement.

Attic

35. Insulation depth. Proper attic insulation is critical for energy efficiency and moisture control. In most US climates, you want R-38 to R-60 (roughly 10–16 inches of blown insulation). Less means elevated heating and cooling costs year-round. 36. Ventilation. Improper attic ventilation causes heat and moisture buildup, which shortens roof life and encourages mold. Confirm that ridge vents and soffit vents are present and unobstructed. 37. Water intrusion signs. Look at the underside of the roof decking for dark staining, soft spots, or visible daylight. Any of these indicates a leak that has been there long enough to matter. 38. Pest evidence. Look for rodent droppings, nesting material, or gnaw marks on wood framing or insulation. Squirrels, bats, and mice cause expensive damage that often goes undetected for years.

The 5 Questions to Ask the Listing Agent on Every Tour

39. How long has this home been on the market, and have there been any previous contracts that fell through?

Homes that sat or had deals fall through usually have a reason. Understanding why gives you negotiating leverage and important due diligence information.

40. What are you aware of that I should know?

Listing agents have disclosure obligations. Asking this directly — and in front of a witness — can surface information not captured in the listing or seller disclosure form.

And three more you should always ask:

• When was the roof last replaced?
• Has there ever been any water intrusion or flooding in the basement or crawlspace?
• Are there any pending or planned HOA special assessments?

What to Photograph on Every Tour

Before you leave, photograph:

• Any ceiling stains, wall cracks, or visible damage you want the inspector to evaluate
• The electrical panel (front and inside — capture the breaker labels)
• Water heater and furnace (manufacture date labels)
• Under-sink areas with any staining or damage
• Foundation exterior where you noticed cracks
• The roof from the driveway

A thorough photo record from the tour makes it much easier to brief your home inspector — and to compare your impressions clearly when you're deciding between two properties on the same day.
