An impressive 50% of prospective homebuyers say their top priority when it comes to neighborhood features is having friendly neighbors, says a recent Berkshire Hathaway HomeServices Homeowner Sentiment Survey.

This feature ranked higher for survey respondents than school district (at 41%), financial considerations (39%), and perceived investment value (37%).

The results reflect well on the common sense of today’s homebuyers. After all, a difficult or hostile neighbor can impact your personal financial considerations (for instance, if you get into a dispute over something like who pays for a damaged fence, and end up bringing or facing a lawsuit).

And a difficult neighbor can impact your home’s investment value, if a major issue makes the house harder to sell (“Pay no attention to that 12-foot spite fence, we’re suing the neighbor to take it down, tempted though we are to take a chainsaw to it.”)

At least neighbor problems don’t typically bring down an entire school district. But they can make life miserable, in the very place where you want to feel safe and relaxed.

But the question remains, why do so few people ask probing questions about a house’s neighbors before they buy? I can only report anecdotally, but as someone who visits open houses regularly, has sold a house that brought in multiple offers, and regularly talks to people about real estate, it seems that the matter of neighbor relations is often left for a post-closing surprise.

Real estate agents certainly know how important the neighbor issue is. I recently visited an open house at the property next to mine, introduced myself and was told by the agent, “Oh good! I can tell people I’ve met the neighbor!” (I guess the subtext was that I looked normal, phew.)

You now know why we included neighbor issues on the “Questions for Seller” worksheet that’s included in Nolo’s Essential Guide to Buying Your First Home. You can certainly get specific in your questioning, too, as in, “We notice the house across the street has five motorcycles parked on the front lawn. Has that led to issues with noise or anything?”

And there’s no need to stop with questions to the home seller. Try asking local friends for information, particularly those who follow any neighborhood listservs. They might tell you who the local “trolls” are, and know about other neighbor issues, disputes, or subjects of tension.

Also, as you go in and out of open houses, ask people on the street how they like living there, and how friendly the neighborhood generally. If you’re lucky enough to spot one of your prospective new home’s neighbors outdoors, perhaps weeding or walking the dog, definitely engage that person in conversation. You may be surprised at what you find out.
