Home Inspection Checklist: What to Check Before Buying Any Property

Introduction

Every property looks good during a broker-guided visit. But hidden defects—structural issues, water damage, electrical problems—can cost lakhs to fix. This inspection guide helps you look beyond the fresh paint and staged furniture.

When to Inspect

Multiple Visits Required

Best Conditions for Inspection

• Daylight (for natural light assessment)
• After rain (reveals waterproofing issues)
• Peak traffic time (for noise assessment)
• Weekend (for neighbor/parking check)

Exterior Inspection

Building Facade

Check for:

• Cracks in external walls
• Paint peeling or discoloration
• Water stains on external walls
• Balcony slab condition
• Window frame condition
• Drainage pipe condition

Red flags:

• Horizontal cracks (structural concern)
• Rust stains from reinforcement bars
• Bulging walls
• Multiple patch-up repairs

Common Areas

Check:

• Lift condition and age
• Staircase lighting and ventilation
• Fire safety equipment
• Parking area drainage
• Compound wall condition
• Security arrangements

Terrace (if accessible)

Check:

• Waterproofing condition
• Slope toward drains
• Parapet wall condition
• Water tank condition
• No stagnation signs

Interior Inspection

Walls

Visual check:

• Vertical alignment (use plumb bob or level app)
• Surface smoothness
• Paint quality and finish
• No dampness or water marks
• No efflorescence (white powder deposits)

Tap test:

• Tap walls with knuckles
• Hollow sound = plaster not bonded properly
• Solid sound = good bonding

Moisture check:

• No hollow sounds (tap test)
• Pattern matching at joints

Tap test method:

1. Use wooden stick or coin
2. Tap every 4-5 tiles
3. Note hollow-sounding tiles
4. More than 5% hollow = problem

Water test (if permitted):

• Pour water in bathroom
• Check if it flows to drain
• No accumulation should remain

Doors

Each door check:

• Opens and closes smoothly
• No rubbing on floor or frame
• Lock operates properly
• Hinges tight and aligned
• No warping
• Door stopper present
• Weatherstrip on main door

Common problems:

• Swelling in monsoon (wood quality issue)
• Lock misalignment
• Hollow core doors used instead of solid

Windows

Each window check:

• Opens and closes easily
• Locking mechanism works
• No gaps when closed
• Glass intact, no cracks
• Mosquito mesh frame works
• Sealant around frame intact
• No water marks below window

Sliding window specific:

• Rollers move smoothly
• Tracks clean and aligned
• No gaps at meeting point

Plumbing Inspection

Water Supply

Test all taps:

• Hot and cold water flow
• Adequate pressure (especially higher floors)
• No rust in water
• Mixer valves work
• Showerhead flow adequate

Pressure test:

• Open multiple taps simultaneously
• Check if pressure drops significantly
• Morning (7-9 AM) is peak usage time

Drainage

Test all drains:

• Kitchen sink drains quickly
• Bathroom floor drains work
• Toilet flushes completely
• No gurgling sounds
• No bad odors from drains

Bucket test:

• Fill bucket with water
• Pour quickly into floor drain
• Should drain in under 30 seconds
• No backflow from other drains

Leakage Signs

Check:

• Under all sinks (open cabinet)
• Around toilet base
• Behind washing machine area
• Water heater connections
• AC drain pipe area

Electrical Inspection

Basic Checks

Every room:

• All switches work (flip each one)
• All sockets have power (use phone charger)
• No sparks when plugging devices
• No burning smell
• Switch plates not hot

Distribution Box

Check:

• All MCBs labeled
• ELCB/RCCB present
• No exposed wiring
• Proper earthing (green wire)
• No rust or burn marks

Power Load

Test high-power points:

• AC points have separate MCB
• Geyser points adequate (15A)
• Kitchen has sufficient points
• Microwave/oven points rated correctly

Safety Features

Must have:

• Earthing for all sockets
• ELCB for safety cutoff
• MCB for each circuit
• No exposed wiring anywhere

Structural Assessment

Crack Analysis

Types of cracks:

Measure cracks:

• Use credit card (0.75mm thick) as reference
• If card fits in crack, it needs professional evaluation

Foundation Issues

Signs:

• Doors/windows don't close properly
• Visible cracks in floor
• Uneven floors (use marble test)
• Cracks in external walls at foundation level

When to Hire Structural Engineer

• Wide cracks (>1mm)
• Multiple diagonal cracks
• Building over 15 years old
• Any concern about structural integrity
• Cost: ₹10,000-25,000 for inspection report

Ventilation and Light

Natural Light

Each room:

• Adequate window size
• Light reaches all corners
• No permanent shadows from adjacent buildings
• Balcony doesn't block light

Test:

• Visit at different times of day
• Check if you can read without artificial light

Ventilation

Check:

• Cross-ventilation possible
• Bathroom has exhaust provision
• Kitchen has chimney outlet
• No stale smell in any room

Smoke test:

• Light incense stick
• See smoke movement toward windows
• If smoke stagnates = poor ventilation

Environment Assessment

Noise

Check:

• Traffic noise (visit during rush hour)
• Noise from neighbors (thin walls?)
• Noise from common areas
• Airport/railway/industrial noise

Acceptable levels:

• Bedroom: <40 dB (library quiet)
• Living room: <50 dB (normal conversation)

Privacy

Check:

• Views from neighboring buildings
• Overlooking by higher floors

• Transformer/substation proximity
• Mobile tower distance
• Water body/nala nearby
• Construction sites impact

Resale Property Special Checks

Age-Related Issues

5-10 years old:

• First signs of waterproofing failure
• Plumbing joint wear
• Electrical load adequacy

10-20 years old:

• Significant waterproofing issues
• Pipe replacement may be needed
• Rewiring possibly required
• Lift modernization needed

20+ years old:

• Major repairs likely imminent
• Structural assessment essential
• All systems need evaluation
• Redevelopment potential

Previous Owner Questions

Ask:

• Any major repairs done?
• Any recurring problems?
• Reason for selling?
• Maintenance history?
• Neighbor disputes?

Inspection Tools

Basic Kit

Professional Inspection

When to hire:

• Building over 10 years old
• Property above ₹1 crore
• Any structural concerns
• Under-construction building

Cost: ₹5,000-20,000 depending on property size

What they check:

• Structural integrity
• Electrical safety
• Plumbing systems
• Fire safety
• Provide detailed report

After Inspection

Documenting Issues

1. Photograph each issue
2. Note location precisely
3. Categorize: Minor/Major/Deal-breaker
4. Estimate repair cost
5. Use for negotiation

Using Findings in Negotiation

Minor issues (₹50,000-2 lakh repairs):

• Negotiate equivalent price reduction
• Or get seller to fix before purchase

Major issues (₹2-5 lakh repairs):

• Significant price negotiation
• Get repair guarantee in writing
• Consider walking away

Deal-breakers:

• Structural issues
• Title problems
• Illegal construction
• Walk away, no negotiation

Conclusion

A thorough inspection takes 2-3 hours per property. It's tedious but essential. The cost of missing a major issue far exceeds the time spent inspecting. When in doubt, spend ₹10,000-20,000 on professional inspection—it can save lakhs in future repairs and give you negotiation leverage.
