How can I know when it was the last housing boom?

[Yisroel Kaufman]

Hello Everyone

I'm a newbie here, I hope this doesn't sound stupid. But I really want to know.

I'm reading now J Scott's book, The Book On Flipping Houses (for the second time). He talks in chapter 5 about what kind of houses to buy. Among others, he says you should be looking for houses built after the last housing boom. While I'm not even sure what a housing boom is, (I think it's something like a housing bubble. Isn't it? hay, would anyone help me with that too...?) I would like to know how I can know when it was the last housing boom in my market, which by the way is NJ. Or, to be more specific, Trenton NJ. I tried Google but didn't find anything there.

I know that here on BP we have people that are much smarter than Google and Wikipedia. So I really hope someone here will be able to help me.

Thanks y'all!
