Sometimes Location Is Everything For Unexpected Reasons

Why did THAT new listing have so many offers within just a few days?
Sometimes, it's all about location.
Not in the "location, location, location" sense of it being located in a universally amazingly appealing location... but for unexpected and unique reasons...
1. My sister lives next door.
2. I could walk to my office.
3. The backyard neighbor is my friend from college.
Sometimes a house will have an unexpectedly high positive response from buyers... related to location... but not for predictable reasons.
As a seller, just roll with it. :-)
As a buyer, know that it could happen, and that you might have more competition than you anticipated.
As a neighbor, capitalize on it if you're planning to sell anytime soon. :-)
