You’ve finally found a house that checks all the boxes, so now it’s time to make an offer, sign on the dotted line, and book the movers, right? Not so fast. That dream for sale, can turn out to be a real nightmare if the seller failed to disclose a cracked house foundation or pest infestation, and you fail to notice until after closing. Here are five things sellers commonly try to hide during the sales process, and the questions you can ask to suss out the truth.

1. Leaks

Leaky faucets, radiators, ceilings, roofs — you name it, real estate agents, brokers, and sellers might try to temporarily plug that drip to attract offers. But honesty is always the best policy, and admitting your property’s faults can actually work in your favor. An Agent, once showed a home with a ceiling that was falling down; she still got a ton of offers on it and made the sale by being honest that the repairs would be made soon.  Leaks are very common, but they can be fixed very easily before the close.  It doesn’t pay to mask something that isn’t a huge issue and can be fixed. Transparency increases value.

2. Pests

Don’t judge a book by its cover or a house by its pretty wallpaper. A house that looks beautiful could still have termites eating away inside the walls, and disclosure laws about pests vary from state to state. Some states require that sellers tell buyers about potential infestations during the sales process. If you have a sneaking suspicion there are pests taking up residence in your new home, don’t risk it — schedule a pest inspection before closing.

3. Issues with the roof or foundation

Great Neck, NY–based client's fell in love with a house in 2014. Unfortunately, they spotted major cracks in the house foundation that would’ve cost tens of thousands of dollars to repair. “We smelled some mold in the basement and asked the owner if we could cut a small section of sheetrock to check for the source of [the] moisture,” client says. “As we peeled away the sheetrock, we noticed the crack. In the end, we did not buy that house.”

4. Age of home systems

Realty Direct NY agent Amy Kernaghan in Deer Park, NY, sees a lot of sellers who try to hide the ages of water heaters and HVAC systems with two simple words: “Don’t know.” A home inspector can find out that information very quickly, so when in doubt, ask your inspector to look into it. And before you even get to the inspection stage, Amt says, the property disclosure can be telling when it comes to how forthright — and truthful — your seller is. “When it states the bare minimum, we know we are either dealing with a disconnected or un-involved seller who doesn’t really know their home or with a seller who knows there are issues and doesn’t want to disclose them.”

Don’t be fooled

When it comes to buying a new home, don’t limit your questions to just real estate agents. Ask your potential new neighbors about the home as well. “Buyers should first ask the neighbors three sets of key questions, including: ‘Why are the sellers moving?’ ‘Have you seen any repair trucks there lately?’ And ‘Are there any construction problems in the neighborhood?’”

“Being diligent in getting questions answered is an important piece of the puzzle for buyers, who should take every opportunity to get to know as much about the house they are buying from the person who knows it best: the seller.”
