The Home Inspection You Really Need: 5 Overlooked Issues That Could Cost Tens of Thousands
When you’re buying a home, you hope everything is cherry-picked: perfect floors, fresh paint, no worries. But as a certified home inspector, I see a different story behind the scenes. At Interiano Home Inspections, I help clients in Frederick and surrounding MD areas uncover hidden issues before they become costly headaches.
In this blog I’ll walk you through five inspection items that many buyers (and even sellers) overlook — and explain how knowing about them early gives you leverage, peace of mind, and a stronger hand in negotiations.
1. Foundation & Drainage — The Silent Destroyers
One of the biggest mistakes I see is homeowners ignoring how water and soil movement affect a home’s foundation. Features to watch for:
- Cracks in the foundation wall (especially horizontal or stepped cracks) or visible separation between wall and floor. These often signal structural movement. Raleigh Realty+1
- Sloping floors or doors/windows that no longer close easily — signs the structure may be shifting.
- Poor lot grading or downspouts that dump water toward the foundation instead of away from it.
- Crawlspaces with standing water, high humidity, or signs of wood rot.
Why it matters: Foundation issues can cost thousands — in some markets the range runs from a few thousand to tens of thousands. Raleigh Realty
What to do: Before you finalize a purchase, request clearance (or at least an evaluation) of these conditions. At your inspection I’ll point out how the home is draining, what to ask the seller to fix, and whether you may want a structural engineer.
2. Roof, Flashing & Attic Venting — “Out of Sight” Doesn’t Mean “Out of Risk”
When we walk around a home, the roof is often assumed to be “fine,” until we climb the ladder or peer into the attic.
Key angles:
- Age of the roof: If the shingles are nearing end of life (15-20+ years in Maryland depending on material), you may be looking at replacement soon.
- Flashing around chimneys, dormers, skylights: Poor flashing = water intrusion.
- Venting & insulation in the attic: Poor ventilation can lead to heat buildup, which shortens roof life or causes mold growth.
- Signs inside: Water stains, blistered paint, musty smell — don’t assume just because it “looks okay” that it is okay.
Why it matters: Unexpected roof replacement or repairs can derail budgets.
What to do: I’ll inspect the roof and attic, show you any weak spots, and explain what might need attention now vs what can wait.
3. Electrical & Safety Hazards — Don’t Get Shocked by the Numbers
Often under-appreciated during a home inspection: how the electrical system holds up to modern demands and safety standards.
Things I check:
- Service panel age and condition: Are breakers functioning properly? Are there double taps or exposed wiring?
- Proper grounding and bonding: Essential for safety and insurance.
- GFCI outlets where required (kitchens, baths, exterior) and AFCI where mandated.
- Overloaded circuits or DIY wiring changes that may not be permitted.
Why it matters: Beyond safety, if an electrician has to redo major wiring after purchase, that’s a shock financially.
What to do: I’ll walk you through any electrical issues I find, show you how serious (or not) they are, and help you decide whether to ask for repairs or budget for future upgrades.
4. HVAC, Plumbing & Moisture — The Systems We Live and Breathe With
It’s not just the structure — the systems inside the home matter a lot. Something like a furnace or duct problem can turn a cozy home into a money pit.
Key systems I evaluate:
- HVAC age, maintenance history, visible leaks or rust.
- Ductwork condition: Leaks, poor sealing, inadequate insulation.
- Water damage or signs of moisture intrusion: in basements, bathrooms, around windows.
- Plumbing: Corrosion, outdated materials (like lead, older galvanised steel), proper pipe slopes, visible leaks.
Why it matters: A neglected HVAC or moisture problem can impact comfort, health (mold), energy bills — and resale value.
What to do: I’ll point out any system that is near the end of its lifespan or showing tell-tale signs. Then you and your real estate agent can negotiate accordingly (repairs, credits, or maybe walk away).
5. Permits, DIY “Upgrades” & Disclosure Gaps — The Hidden Negotiation Levers
Sometimes it’s not what you see but what you can’t see in a house that matters. That includes whether renovations were done legally and whether disclosures are accurate.
Consider this:
- Was a room added, or was a basement finished, without proper permits? It may not meet code or be insurable.
- Does the seller know (or disclose) prior water flooding, mold, termite damage?
- Are there obvious DIY fixes that look ok on the surface but were done poorly (e.g., electrical, structural modifications)?
Why it matters: These items can affect insurance, liability, safety — and lead to renegotiation or deal collapse.
What to do: I’ll document anything that raises a red flag on these fronts and you’ll walk away with a full report. With that, you can ask questions:
- “Has this been permitted and inspected?”
- “What warranties apply?”
- “Would my insurer accept this condition as is?”
