9 issues that fail a house inspection
Whether or not shopping for a house in Austin, TX or promoting a home in Portland, OR, these are the issues many patrons may think about “failing” the house inspection — and sellers ought to anticipate negotiations round these repairs.
1. Structural or basis repairs
“Once we flag structural points—cracks within the basis, shifting partitions, or sloping flooring—it usually sends patrons operating, particularly if it’s the primary house they’ve thought-about critically,” shares Curt Kloc, founding father of nationwide inspection franchise Inspections Over Espresso.
However what is taken into account “regular” or “regarding” can fluctuate by area, Kloc says.
“In locations like Texas, expansive clay soils could cause seasonal shifting, and minor motion may be frequent—however in areas like Colorado or the Pacific Northwest, even small indicators of settling increase massive purple flags.”
Widespread structural purple flags
- Basis cracks or settling: Small hairline cracks are frequent, however vast, horizontal or stair-step cracks can imply shifting or instability

“Regardless that it’s not included throughout the scope of a standard house inspection, most sensible house inspection firms supply sewer scopes as an add-on service, even on model new houses, the place we’ve discovered the sewer line results in a lifeless finish.”
Plumbing issues can vary from minor annoyances to main hazards. Leaks, outdated piping supplies, and poor water strain might not at all times be seen, however they’ll trigger important hidden harm like mildew, wooden rot, and even structural points.

The largest expense in re-plumbing isn’t simply the pipes themselves, Kloc mentions. “Roughly half the associated fee is plumbing work, however the different half comes from repairing all the things you needed to open up—drywall, paint, tile, and different finishes. So a $10,000 re-plumb can simply flip right into a $20,000 undertaking.”

However remediating electrical points isn’t only a matter of changing the panel. “In lots of instances, your entire system must be evaluated,” Kloc says. “Some houses nonetheless have aluminum department wiring, and relying on the area and the insurer, remediation choices fluctuate.”

“Most cheap sellers will comply with deal with smaller, safety-related fixes: issues like a leaking faucet, a lacking handrail, or a GFCI outlet improve,” says Kloc. “These are the sorts of points that don’t value a lot however convey peace of thoughts to the client.”
The place negotiations usually get difficult, says Kloc, is that if big-ticket gadgets are previous or outdated however nonetheless technically working—“like a 20-year-old roof, a 15-year-old AC unit, or a water heater effectively previous its anticipated lifespan. Consumers see these as near-term bills, however sellers argue, ‘It really works right now, why ought to I substitute it?’”
