Not certainly - it's very common for a neighborhood to shoot up in value (because of something that individual homeowners don't do, like a major employer moving in or getting successful, or a train station being built, or a nearby neighborhood getting full), and so the market value of the same home at the same condition can increase dramatically just because the neighborhood has more demand.
40% in 2-3 years is pretty unlikely, even in the hottest markets. But even still, does that mean you discontinue shopping in the neighborhood altogether? Because all the surrounding homes would have seen the same increase?
Sorry, I mean yes it's uncommon, however it's also predictable. Iif you know where a new factory is going ahead of time that drastically alters the probabilities.
