As home buyers purchase under intense competition, they may be prone to some regrets afterward. About 43% of all home buyers have at least one regret about their purchase, according to a recent Bankrate poll of about 1,400 homeowners. The most common regret is feeling unprepared for home maintenance and other costs associated with homeownership.

Young adults seem to have the most regrets about their recent home purchase. Broken out by age, nearly two-thirds — or 64% — of millennials, ages 25 to 40, say they have at least one regret about purchasing their current home. About 45% of Gen X, ages 41 to 56, have reported buyer’s remorse with their current home, while only 33% of baby boomers, 57 to 75, have housing regrets.

The most common regret is not factoring in unexpected maintenance or hidden costs, such as repair or replacement of roof, air conditioning, water heater or appliances. The question is not whether these expenses will come up, but when and how much they will cost. Other home buyer regrets include high monthly mortgage payment, mortgage rate, size of house (too big or too small), location of house and overpaying for the house. Nearly all these regrets can be prevented ahead of time with a little bit of forethought, due diligence and the advise of a professional real estate agent.

With sight-unseen offers growing or purchases being made during bidding wars and waived contingencies, many important factors can get overlooked when buying a home — only to be pain points in the future. Working with an experienced and reputable agent is now more important than ever.

Real estate professionals are experts at navigating all aspects of the buying, including negotiating on your behalf and overseeing the inspection of the home. they can also explain today’s market and break down what it means for you.
