In an ideal world there would be charming neighborhoods full of houses so perfect you wouldn’t even need to check the water faucets, much less hire a highly qualified home inspector. You could just comfortably make an offer on the house you liked the best and be done with it. Sweet.
OK, welcome back to reality! In the real world, every house needs an inspection before you buy and almost every inspection report is going to come back with at least one very black mark. That means you’re probably going to end up agonizing over the eternal home buyer question: To bolt or not to bolt? Fish or cut bait? Go for the deal or run for the hills?
The answer depends a lot on your tolerance level, but there are a few issues that Realtors† and home inspectors agree are total deal breakers. If you spot these, proceed with extreme caution.
1. Major foundation issues
Foundation issues are a huge undertaking to repair, and our experts agree it tops the list of home-buying deal breakers—especially if you’re a first-time buyer without the extensive funds needed for a lengthy and costly repair.
“Foundation cracks, bulges, and other irregularities can be extremely expensive to repair, and may even involve excavating the soil around the house to stabilize the walls,” says Welmoed Sisson, a home inspector with Inspections by Bob in central Maryland. “So correcting the problem can also mean extensive landscaping repair.”
The problem is, some foundation issues might be minor. The only way to tell is by hiring a licensed structural engineer to get to the root of the problem.
“It’ll be the best $500 you ever spent,” Sisson says.
2. Aluminum wiring
Aluminum wiring, which was popular during the Vietnam War era, isn’t terribly common these days. But if your potential home has it, it could mean big trouble.
“It was cheaper than copper, and builders used a lot of it,” Sisson says. “Problem is, aluminum expands and contracts in the heat more than copper, which causes the connections to loosen up, and then you get fires.”
If the house does have aluminum wiring, an electrician can add copper near the outlets—but that’s akin to putting a Band-Aid on a bullet wound. Odds are, you’ll need to have all the wiring replaced, and that can cost thousands of dollars.
3. Buried oil tanks
Before electrical heating came along, some homes had oil tanks buried in the backyard to funnel propane to the house during winter. Sound scary? It is! And there’s more: Those tanks might still be under the ground, just waiting to wreak havoc.
“These are environmental time bombs,” Sisson says. “If there is any evidence of leaking, the costs to remove a tank can easily exceed $10,000.”
Buried oil tanks are more common in the Northeast, where winters were harsher, but they can be found anywhere—and finding them can be tricky. If they’re active, you’ll see two pipes coming up from the ground. If they were shut off, there won’t be any outward evidence.
4. Polybutylene plumbing pipes
These pipes had their heyday as a cheap alternative to copper in the ’80s, but it didn’t last long.
“They were found to degrade due to the chlorine in municipal water supplies, and would spontaneously leak and cause terrible flooding,” Sisson says.
So all smart homeowners got rid of those pesky pipes, right? Nope—if the pipes haven’t leaked, homeowners tend not to be so quick to replace them. Sisson sees it all the time.
And while the current owners might have skirted by without waking up to an indoor swimming pool, you might not be so lucky.
“The damage is from the inside out, so it’s not visible until it fails and starts spewing water all over your basement,” Sisson says.
The only fix? Total pipe replacement to the tune of $10,000 and up.
5. Upgrades without permits
If you’re buying an older home, odds are someone did some upgrading before you came along. That’s usually a good thing (hello, granite countertops!), but it can be a very bad thing if the homeowner in charge had a DIY streak and a problem with authority.
Most upgrades require a permit from the local county or city. If the homeowner skirted the permit step and something goes wrong later (say, a fire from shoddy wiring or a flood from a busted pipe), you might run afoul of your homeowners insurance company.
“The insurance company will find out the work was not permitted and will most likely deny the claim and cancel the policy, leaving the homeowner on the hook for all the damages,” Sisson says.
But what about mold?
Most of us are worried about mold. Very, very worried. But mold might not be an automatic deal breaker.
That dark stuff you see around the grout lines in your bathtub? Yes, that’s mold. But there’s no reason to go running scared.
“In general, there’s a horror around mold that is unnecessary,” says Joshua Jarvis, founder of Jarvis Team Realty in Duluth, GA. “The challenge is that there is mold that can kill or at least make you sick, so you never want to downplay it.”
If you do encounter the nasty stuff, the best thing to do is have it identified by a qualified inspector. Many mold problems aren’t reason enough to not buy a home, but then again, some are. Have the experts tell you what category this house falls into.
What about bugs?
No question: Bug infestations are intensely gross. No one is thrilled to see roaches running around their potential new kitchen, but very few bug problems are a big deal—with one notable exception: termites.
“They can literally eat your home,” Jarvis says.
If the problem isn’t termites, plan on hiring a good exterminator before you move in and possibly having to deal with a few follow-up treatments.
Inspections cost money, and no one wants to be out the cash and a new house. But do it anyway—even on brand-new builds. You might spend a few hundred upfront, but you could save yourself thousands down the line.
After reading this article, Melissa Christopher, Ocean County, NJ Realtor has the following insight:
The seller is holding his breath waiting to get the all clear, no issues, no repairs, as is the buyer. Don’t be surprised if a couple things come up on the report. But not all are deal breakers. Depending on the home inspector, they may point out door handles that need adjusting which is minor or they may point out one of the above. Clearly the above are much more money than a door handle. The home inspection is the one area that can kill a deal very fast. The buyer may not have any more cash flow to invest in more repairs, the seller may not either depending on their financial situation. Trust the inspector that is hired and call in professionals in the area in which they recommend. A home inspector is not qualified for certain elements such as electrical repair and what it would entail and costs.
