Waiving a home inspection is like purchasing a used car on Craigslist without taking a look under the hood — you’re likely to run into issues down the road. A new survey from the online home improvement marketplace, Porch, reveals that 86 percent of home inspections uncover one or more problems that need to be addressed. While hiring a home inspector will set you back about $377 on average, their expertise could save you from buying a lemon or shelling out thousands of dollars in future repairs.

Prospective homebuyers can use the information provided by a home inspector to negotiate a lower sales price, accounting for the cost of repairs or replacing a feature altogether. Of the 1,000 individuals surveyed by Porch who hired a home inspector, 37 percent submitted a revised offer with help from their real estate agent, saving an average of $14,000 off the listing price of their new home. That’s no small chunk of change!

Here we examine the most-flagged home inspection issues buyers can use to negotiate the best sale price.

1. Roof – flagged in 19.7% of reports

Roofs with asphalt or cedar shingles have an average lifespan of 20 years whereas metal roofs only need to be replaced every 50 to 75 years. Your home inspector will look for signs of water damage, mold or algae, and take note of any sagging or missing shingles.

2. Electrical – flagged in 18.7% of reports

If you’re looking to purchase a home built prior to the 1950s, you’ll want to inquire about its electrical wiring. Knob-and-tube wiring, which was popular from the 1880s to the 1940s, can cause electrical shocks and fire. Other issues to take note of include exposed wiring, ungrounded wire receptacles and paint on electrical outlets.

3. Windows – flagged in 18.4% of reports

While broken windows are a pretty obvious spot, your home inspector may conduct a simple test to check for air leaks. However, there’s no guarantee the home owners will agree to repair the window seals — some consider this cosmetic, rather than structural.

4. Gutters – flagged in 16.9% of reports

Your home inspector will want to make sure the gutters are in good working condition, assessing their size, any damage, and how far water is directed away from the house.

5. Plumbing – flagged in 13.6% of reports

Plumbing problems can quickly add up, costing an unsuspecting homeowner thousands of dollars. With a flashlight in hand, your home inspector will scan for potential leaks, polybutylene piping, DIY projects gone wrong, tree root damage, and more.

6. Branches overhanging roof – flagged in 13.3% of reports

Having an old-growth tree in your front yard might seem like a selling point, but it can actually cause a lot of damage if not properly maintained. Branches can rip off roof shingles, leaves can pile up and clog up your gutters, and heavy limbs can come crashing down into your living room.

7. Fencing – flagged in 12.6% of reports

Home inspectors will evaluate the condition of a fence that lines the property. But again, this is one of those “choose your battles” situations. Are you willing to risk losing out on your dream home because a few pickets have gone missing? Probably not.

8. Water heater – flagged in 12.2% of reports

While a rickety fence may be no big deal, a busted up water heater certainly is. Home inspectors check for things like water leaks, sediment buildup, corrosion on the pipes, and low water pressure.

9. Driveways, sidewalks, patios, entrance landing – flagged in 11.9% of reports

Cracks in your driveway or patio are pretty much inevitable. That being said, you’ll want the home inspector to ensure water isn’t seeping into those crevices. If major issues do turn up, you may be able to seek compensation for those repairs.

10. Air conditioning – flagged in 9.9% of reports

According to the Porch survey, most homebuyers negotiate only $500 for AC repairs, but the actual costs are much higher — think thousands of dollars, not hundreds.

11. Exterior paint – flagged in 9.6% of reports

If the house was constructed before 1979, your inspector will likely conduct a lead paint test. Additionally, if the exterior paint is peeling, some lenders (like the Federal Housing Administration and Veterans Affairs) will not approve the loan due to concerns over health and safety.

12. Foundation issues/cracks – flagged in 8.9% of reports

Home inspectors can look for obvious signs of foundation problems like cracks in basement walls, damaged bricks and uneven floors. If you and your home inspector suspect the problems are serious, you may want to bring in an engineer. But consider it money well spent — foundation fixes can cost $10,000 or more. Gulp.
