I tell every buyer I work with the same thing before their home inspection.
A home inspection is not a pass or fail test. It is information. Every home — new or old — will have an inspection report with findings. The question is not whether there are findings. The question is which ones matter, which ones are negotiable, and which ones are reasons to walk away.
That distinction is everything.
I have walked through hundreds of inspection reports with buyers in Gilbert, Chandler, Queen Creek, Mesa, and across the East Valley. Here is what I have learned about which findings are worth fighting for and which ones should give you pause.
Findings That Are Normal — Do Not Panic
Before I get to the red flags, let me tell you what is normal in an Arizona home inspection so you do not spend your energy worried about the wrong things.
Minor grading and drainage issues near the foundation — common in desert homes. Small hairline cracks in drywall or exterior stucco — typical settling in the Arizona climate. GFCI outlets that need updating in bathrooms and kitchens — a simple fix, very common in older homes. Minor roof flashing issues — often inexpensive to repair. Window screens with small tears — expected. Aging water heater still functioning within its expected lifespan — note it for your planning but not a crisis. Smoke and carbon monoxide detectors that need updating — easy fix.
These findings appear on nearly every inspection report. They are negotiating points not deal breakers.
The Real Red Flags — Know These Before Your Inspection
Red Flag 1 — Foundation and Structural Issues
This is the most serious category in any home inspection. The foundation is what everything else sits on. If it fails, the cost to repair is extraordinary.
What to watch for: Horizontal cracks in foundation walls — these indicate lateral pressure and are far more serious than vertical cracks. Stair-step cracks in brick or block. Walls that are bowing or leaning. Floors that are noticeably uneven. Doors and windows that stick or will not close properly — this can indicate foundation movement. Gaps between walls and the ceiling.
Cost reality: Foundation repairs can range from $10,000 to $50,000 for moderate issues. Severe structural failures can exceed $100,000. This is a category where I strongly recommend bringing in a structural engineer if the inspector flags anything concerning.
Arizona-specific consideration: Desert soil conditions and expansive clay in some areas can contribute to settling or movement. This makes foundation inspection particularly important here.
When to walk away: Active foundation movement with significant cracking and displacement. Unless the price is dramatically reduced to account for repairs and you are prepared to manage a major project — this is a legitimate reason to walk away.
Red Flag 2 — Roof Condition
In Arizona, the roof takes an extraordinary beating. Extreme heat, monsoon storms, UV radiation, and hail all take their toll. A failing roof can allow water intrusion that cascades into mold, structural damage, and insulation failure.
What to watch for: Missing or damaged shingles. Active leaks or water staining on ceilings inside the home. Deteriorated or missing flashing around chimneys, vents, and skylights. Improper installation that allows water intrusion during monsoon season. Tile roofs — very common in Arizona — with cracked or missing tiles and damaged underlayment.
Cost reality: A full roof replacement on an East Valley home can run $8,000-$25,000+ depending on size, material, and access difficulty.
What to negotiate: Request the seller repair specific deficiencies or provide a credit at closing. If the roof is near end of life but still functional, a credit toward future replacement is a reasonable ask.
When to walk away: Active leaks that have caused water damage. A roof that needs immediate full replacement and the seller refuses any concession.
Red Flag 3 — Water Damage and Moisture Issues
Water is the enemy of a home. In Arizona we may be in a desert, but moisture damage is absolutely a reality — from roof leaks, plumbing failures, poor window sealing, and monsoon season water intrusion.
What to watch for: Water stains on ceilings or walls — especially brown rings or discoloration. Musty odors anywhere in the home. Visible mold growth on walls, ceilings, or around windows. Soft or spongy flooring — especially in bathrooms and kitchens. Efflorescence — white powdery deposits on concrete or block walls — indicates moisture movement.
Watch for: Sellers who use excessive air fresheners or have freshly painted basement walls or bathroom areas — these can mask moisture issues that they know about. Large pieces of furniture placed against walls in unusual positions. Drapes that cover windows in rooms where you would not expect them.
Cost reality: Mold remediation alone can run $3,000-$15,000+. If moisture has caused structural rot the costs escalate dramatically.
When to walk away: Extensive mold that has penetrated walls, floors, or structural elements. Active water intrusion with no clear solution.
Red Flag 4 — Electrical System Problems
Outdated or faulty electrical systems are both a safety hazard and a significant renovation cost. In Arizona’s extreme heat, electrical systems are under constant stress from heavy air conditioning loads.
What to watch for: Federal Pacific Electric panels (Stab-Lok) or Zinsco panels — these brands are notorious for failing to trip during overloads and are considered fire hazards. Many insurers refuse to cover homes with these panels. Aluminum wiring in the branch circuits — common in homes built in the late 1960s and 1970s, can create fire hazard without proper connectors. Knob-and-tube wiring in older homes. Signs of DIY electrical work — exposed wiring, mismatched wire gauge, ungrounded outlets in areas that require grounding. Burn marks or rust inside the electrical panel.
Cost reality: Replacing an electrical panel runs $2,000-$5,000. Full rewiring of a home can run $8,000-$20,000+. Insurance implications can be significant.
Arizona-specific consideration: Many older Arizona homes built in the 1970s-1990s may have original panels that are approaching end of life under heavy AC load. Ask specifically about the age and brand of the electrical panel before the inspection.
When to walk away: Multiple electrical hazards combined, particularly a failed panel brand plus aluminum wiring plus unpermitted work. This is a category where you can quickly be looking at $15,000-$30,000 in repairs.
Red Flag 5 — HVAC — Especially Critical in Arizona
I want to emphasize this more strongly for Arizona buyers than for buyers anywhere else in the country.
Your air conditioning system is not optional here. In July and August in the East Valley, temperatures regularly exceed 110 degrees. An AC failure in summer is a genuine emergency. A failing or undersized AC unit should be taken very seriously in Arizona in a way that buyers from cooler climates may not fully appreciate.
What to watch for: An HVAC system that is 15+ years old — average lifespan is 12-15 years in Arizona’s extreme heat climate. Inadequate cooling for the home’s square footage. Poor airflow from vents. Refrigerant leaks. Unusual noises during operation. Units that are running but not adequately cooling.
Cost reality: An AC replacement in Arizona can run $5,000-$15,000+ depending on system size, brand, and efficiency rating.
What to negotiate: If the unit is aging but functional, request a credit or a home warranty that specifically covers AC replacement. This is one of the most common and reasonable negotiation points I see in East Valley transactions.
When to walk away: A unit that has already failed and the seller will not repair or provide credit for replacement. This is not a situation to inherit.
Red Flag 6 — Termites and Pests
Arizona is termite country. The state has several termite species including some of the most aggressive in North America — the desert subterranean termite can cause significant structural damage before homeowners even notice.
What to watch for: Mud tubes on foundation walls or in crawl spaces. Hollow-sounding wood when tapped. Damaged wood that appears eaten from the inside. Discarded wings near windows and doors. Evidence of prior treatment without current warranties.
Recommendation: Always get a separate termite/pest inspection in addition to the general home inspection. Many lenders require it. In Arizona, it is non-negotiable.
Cost reality: Termite treatment can run $1,000-$4,000 depending on infestation severity. Structural repairs from termite damage can run into the tens of thousands.
What to negotiate: If active termites are found, require the seller to treat before closing. If prior damage exists, get a repair credit.
Red Flag 7 — Unpermitted Work
Work done without permits is a significant issue because it can create safety risks, complicate resale, and become your financial responsibility the moment you take ownership.
What to watch for: Room additions, garage conversions, or structural modifications that do not appear on the property’s permit history. Electrical or plumbing work that does not meet current code. Pool or spa additions without permits.
How to check: Your realtor can pull the permit history for any property through the city or county records.
Cost reality: Bringing unpermitted work up to code or removing it can be expensive. Lenders sometimes refuse to finance homes with significant unpermitted additions. And when you go to sell — a future buyer’s inspector will find the same issues you found.
How to Use Inspection Findings to Negotiate
Finding a red flag is not the end of the deal — it is the beginning of a negotiation. Here are your options when a significant issue is found:
Request the seller repair the issue before closing — get written confirmation and verify the repair is completed during your final walkthrough.
Request a credit at closing — you take the money and manage the repair yourself after closing. This is often the cleaner option.
Request a price reduction — if the repair is significant, a lower purchase price reflects the true condition of the home.
Walk away — within your inspection contingency period, you can cancel the contract and receive your earnest money back in full if you cannot reach a resolution.
The right strategy depends on the severity of the issue, the seller’s motivation, and the market conditions. I negotiate these situations for my buyers every single week.
One Final Thought on Home Inspections
Never skip a home inspection. I have never — not once — had a buyer regret getting an inspection. I have had buyers regret not getting one.
In today’s East Valley market where homes are averaging 55-90 days on market, there is no situation that justifies waiving this protection. The $300-$600 you spend on an inspection is the best money in the entire transaction.
Let me help you find a great inspector and navigate whatever the report reveals.
