Red flag No. 1: Too much scent
Don’t let those freshly baked cookies or potpourri simmering on the stove fool you. The more aggressive the scent, the greater the likelihood the seller is taking precautions to mask a more offensive odor. When there is too much going on in the scent deparment, you might wonder what they are trying to hide.
Take a deep whiff in every room you enter, and look closely at walls, ceilings, and flooring for signs of pet accidents, mildew, or smoke.
Red flag No. 2: Poor tiling
Inspect the tile in kitchens and bathrooms. If the gaps or tiles are slightly uneven, it may indicate a DIY job, which could make you think twice, especially if you the house was flipped. Lazy tiling could indicate that multiple fixes might have been done on the fly, which can add up to big bucks in potential repair costs.
Red flag No. 3: Foundation issues
Most houses have hairline cracks, which just indicate the house is settling into its position, but large gaps signal a bigger issue with the foundation.. Other tipoffs: sticking doors or windows, visible cracks above window frames, and uneven floors. How do you know if the floors are uneven? Roll a marble from one side to the other.
Red flag No. 4: Signs of deferred maintenance
Look for signs that the owner might have neglected routine home maintenance, such as burned-out light bulbs, long grass, leaky faucets, or faded paint. These signs indicate the seller may have ignored other ongoing home maintenance tasks that can cause real problems down the road.
An attentive homeowner is going to flush the water heater annually, change air filters monthly, clean the chimney, inspect the roof for leaks, and regularly recaulk around windows and doors, for example, which will keep all those systems in good working order.
Red flag No. 5: Nearby water
That creek might look picturesque now, but it won’t when it comes cascading through your back door. The increasing unpredictability of weather means that it’s vital to consider the possibility of flooding. We've seen people unable to ensure their house against flood risk, which can create giant damage bills on a regular basis.
Red flag No. 6: Wonky windows
Take a second to pull back the curtains to check for lopsided frames, and then give the windows a tug to make sure they slide easily. If they stick, it could be a sign of foundation issues, as noted above, or just poor installation.
The only fix for that—and it’s an expensive one—is new windows.
Red flag No. 7: Mold
To detect possible signs of mold while wandering through an open house, discreetly open bathroom and sink cabinets to take a look around water pipes or drains. Even small black or gray spots indicate that more serious issues may be lurking. You can also check the caulking around faucets and tubs for black spots, and look for patches on the ceiling.
Red flag No. 8: Water damage
A musty odor can indicate water damage, even if you don’t see standing water. Check walls and ceilings for water lines; they likely indicate flooding from a leak or a burst pipe that may have caused internal damage. Also, take a peek at exposed piping in basements or laundry rooms, and check for rust, water stains, or leaking.
Red flag No. 9: Cosmetic enhancements
That one freshly painted wall could be an accent wall, or it could be hiding something like a patch of mold.
Red flag No. 10: Improper ventilation
Without adequate interior ventilation, moisture sticks around, which can create mold and increase allergies. The tipoff: Look for condensation on windows or slightly bubbled or peeling paint around windows, doors, or vents. This can indicate moisture in the walls and ceiling drywall.
The bottom line: Don’t walk through an open house the way you walk through a museum. Even though your home inspector is likely to detect many of these problems down the line, being attentive to these red flags in an open house ensures that you’re not wasting your time on a home that isn’t the one for you.
