What Is a Home Inspection?
Complete Guide to the Home Inspection Process
Buying a home is probably the biggest purchase you’ll ever make. A home inspection protects that investment by uncovering hidden problems before you sign the papers.
But what exactly is a home inspection? Who needs one? What does it cost? And what happens on inspection day? This guide answers all your questions.
What Is a Home Inspection?
A home inspection is a thorough, professional evaluation of a property’s physical condition. A licensed home inspector examines the structure, systems, and components of a house—from the roof to the foundation, and everything in between.
The inspection typically takes 2-4 hours for an average-sized home. The inspector walks through every room, tests systems, opens access panels, and uses specialized tools (like thermal imaging cameras) to spot problems invisible to the naked eye.
At the end, you get a detailed written report documenting the home’s condition, any issues found, and recommendations for repairs or further evaluation.
Why Home Inspections Matter
Protect Your Investment
The average home in Arizona costs $350,000+. A $400 inspection that reveals a $30,000 foundation problem or a failing HVAC system is one of the smartest investments you can make.
Negotiate Better Deals
Inspection reports give you leverage. If major issues surface, you can:
- Negotiate a lower price
- Ask the seller to make repairs
- Request a credit toward repairs after closing
- Walk away if problems are too severe
Plan for Future Repairs
Even if nothing is “wrong,” inspections reveal the age of major systems. Knowing your roof is 18 years old or your water heater has 5 years left lets you budget for replacements before they fail.
Peace of Mind
You’ll know exactly what you’re buying. No surprises after closing.
The Inspection Process: Step by Step
Before the Inspection (24-48 hours prior)
Schedule your inspection contingent on your purchase agreement. Arizona inspections typically happen 7-10 days after your offer is accepted—enough time for underwriting but quick enough to catch problems.
Day of Inspection
Plan to attend. This is your chance to ask questions and learn about your potential home.
Your inspector will:
- Walk the exterior: Check roof, siding, gutters, foundation, drainage
- Test HVAC: Run air conditioning and heating to confirm they work
- Check electrical: Test outlets, inspect the main panel, verify proper grounding
- Inspect plumbing: Test water pressure, run drains, check for leaks
- Evaluate structure: Look for cracks, settle, or water intrusion
- Use thermal imaging: Find hidden moisture, air leaks, and electrical problems
- Document everything: Photos, measurements, condition notes
See the complete checklist of what inspectors examine—and print it to bring along.
After the Inspection (24-48 hours later)
You’ll receive a detailed report. Most Arizona inspectors deliver reports within 24 hours via email. The report includes:
- Photos of problem areas
- Severity ratings (safety hazard, needs repair, monitor condition)
- Detailed descriptions of issues
- Inspector’s recommendations
- Age and condition of major systems

How Much Does a Home Inspection Cost?
In Arizona, typical home inspection costs range from $300-$550.
Price depends on:
- Home size: Larger homes take more time
- Home age: Older homes may need deeper inspection
- Add-ons: Thermal imaging, radon testing, or pool inspection cost extra
- Inspector experience: Licensed, experienced inspectors charge more than new inspectors
- Location: Phoenix urban inspections may be cheaper than outlying areas
How to Prepare for Your Home Inspection
Make the Home Accessible
If you’re the seller:
- Unlock all doors and access points
- Ensure the attic hatch, basement, and crawlspace are accessible
- Make sure utilities are on
- Clear pathways to the main electrical panel and water shut-off
Ask Your Inspector Questions
As a buyer, bring a list of concerns:
- “How old is the roof? When will it need replacement?”
- “Is the A/C original? How long until it fails?”
- “What are the most serious issues here?”
- “Are there signs of termites or water damage?”
Consider Specialized Inspections
Standard inspections have limits. You might want additional evaluations for:
- Pest inspection: Termites, rodents, other pests
- Radon testing: Invisible, dangerous gas common in Arizona
- Mold inspection: If you suspect mold beyond visual assessment
- Pool inspection: If the home has a pool or spa
- Septic inspection: If not on city sewer
What to Do With Your Inspection Report
Review It Carefully
Don’t just skim the summary. Read the full descriptions of issues. Understand severity levels and what they mean for you.
Get a Contractor’s Quote (If Needed)
If major issues surface, get repair estimates from licensed contractors. A $2,000 inspection finding might need a $15,000 fix—or it might be a quick $500 repair.
Decide Your Next Move
Common options:
- Renegotiate: Ask the seller to lower the price or make repairs
- Request credits: Seller gives you money at closing to fix issues yourself
- Proceed as-is: Accept the home’s current condition
- Walk away: Use inspection findings as your exit if problems are severe
Schedule Follow-Up Inspections (If Needed)
For major issues, hire a specialist:
- Structural engineer: For foundation cracks or settling
- HVAC contractor: For air conditioning concerns
- Roofer: For roof damage or end-of-life concerns
