First, a Clarification
Home inspections do not pass or fail. An inspection is a documentation exercise — the inspector describes the condition of every accessible system, grades severity, and delivers a report. The buyer, seller, agent, and lender then decide whether what is in the report is a deal-breaker, a price adjustment, or a list of things the buyer will own after closing.
That said, certain findings reliably kill deals or force renegotiation. If you are buying in Flint, Genesee County, or the surrounding Mid-Michigan region, here is what to watch for.
1. Major Roof Issues
Active leaks, widespread granule loss, lifted shingles, damaged flashing, and end-of-life roof coverings are among the most common deal-impacting findings in Michigan. Our winters are especially hard on roofs — ice dams, snow load, and freeze-thaw cycles accelerate aging — and a 20-year-old roof that looks fine from the curb is often at the end of its useful life.
Replacement cost in the Flint area runs $8,000–$25,000 depending on material and pitch. That is a number that buyers either negotiate around or walk away from.
Our home inspection in Flint, MI includes full roof and attic evaluation with thermal imaging.
2. Foundation and Basement Issues
Horizontal and stair-step cracking, bowing walls, settlement, active water intrusion, and failed waterproofing systems are consequential findings. Michigan's clay soils and freeze-thaw cycles push foundations around more than most regions; most older Flint-area homes show some movement, and the job of the inspector is to distinguish normal wear from active problems.
3. Electrical Hazards
The electrical findings that reliably force negotiation:
- Federal Pacific Stab-Lok panels (known failure-to-trip defect)
- Zinsco and Sylvania panels with the same reliability concerns
- Knob-and-tube wiring still in active use (common in pre-1940 Flint homes)
- Aluminum branch wiring without proper termination
- Double-tapped breakers, open splices, and missing GFCI protection in required locations
Insurance underwriters increasingly refuse to write policies on homes with Federal Pacific panels or active knob-and-tube, which can make the issue a financing problem, not just a safety problem.
4. Plumbing End-of-Life
Galvanized steel supply lines and lead service lines — still present in a real fraction of pre-1960 Flint homes — are significant findings. So are failed water heaters, active drain leaks, polybutylene supply lines (rare in this area but not zero), and undersized supply piping.
The line from the house to the city main is the hidden expensive one. A sewer scope inspection in Flint, MI is the only way to find cracked clay lines, failing Orangeburg pipe, or root intrusion before closing — and repair costs of $5,000–$15,000 are routine when those issues come up.
5. HVAC Failure or End-of-Life
A cracked heat exchanger is a safety issue that must be addressed before the home can be legally occupied. Aging boilers, gravity furnaces (still present in some older Flint homes), failed air conditioning, and end-of-life water heaters all become negotiation points.
For older homes especially, thermal imaging during the inspection often reveals distribution issues — blocked ductwork, disconnected returns, uninsulated supply runs in unconditioned spaces — that a visual-only inspection would miss.
6. Moisture, Mold, and Crawlspace Problems
Visible mold, water staining, failed vapor barriers, and actively wet crawlspaces are among the most common moisture findings in the Flint area. Michigan humidity plus basement-and-crawlspace construction plus undersized bathroom fans venting into attics add up to a near-universal moisture issue on older homes.
See mold inspection in Flint, MI for how we document and diagnose these — and critically, identify the moisture source so remediation does not come back.
7. Radon
EPA places most of Lower Michigan — including Genesee, Lapeer, Shiawassee, and Oakland Counties — in elevated radon zones. A level above 4.0 pCi/L typically requires mitigation, which runs $1,200–$2,200 in the Flint area. Buyers increasingly make radon a non-negotiable part of the inspection contingency. See radon testing in Flint, MI.
8. Insurance- and Lender-Specific Issues
Some findings do not affect safety directly but affect whether the home is financeable or insurable:
- Roof age over 20 years — some insurers will not write, or will only offer actual-cash-value rather than replacement-cost policies
- Federal Pacific / Zinsco panels — uninsurable with several carriers
- Active knob-and-tube — uninsurable with most carriers
- Manufactured homes without HUD foundation certification — unfinanceable with FHA or VA
- Peeling paint on pre-1978 homes with FHA financing — requires stabilization before closing
A Board Certified Master Inspector report flags all of these clearly so your lender and agent are not surprised at the closing table.
How to Handle "Failing" Findings
When an inspection reveals serious issues, buyers generally have four options:
- Negotiate a price reduction covering the estimated repair cost
- Require seller repairs before closing, documented and re-inspected
- Take a closing credit and make repairs themselves afterward
- Walk away using the inspection contingency
Which path is right depends on the specific finding, the market, and how many other issues are stacked on top. This is where having a good agent and a thorough inspection report matters — the report is the leverage.
The Best Defense for Sellers
Sellers can head off most deal-killing inspection findings by ordering a pre-listing inspection in Flint, MI before the home goes on the market. You find the problems on your timeline, fix what you want to fix, disclose the rest, and price accordingly — rather than reacting to a buyer's inspector under a closing deadline.
That is almost always the cheapest way to handle Michigan's older housing stock.
