Welcome back to The Brokerbabble Glossary, where Curbed takes a word or phrase that shows up repeatedly in listings and deciphers its true meaning. Ideas? Hit up the tipline.
One way of looking at this is that every listing is a "once in a lifetime" opportunity to live in that particular house. If somebody else buys it, they'll probably stay there for years and years. Sure, they might decide to upgrade after a little while and the house could go back on the market. And then maybe the next owner will die in some sort of freak accident. And the lady after that could lose it in a card game, but this is a four or five times in a lifetime opportunity at most. Six, maybe. Of course, if you're not that particular about which bland two-bedroom house in Louisville you want to buy, the options start to open up. But owning this particular type of place is really only a thousands-of-times- in-a-lifetime opportunity. At most.
The notable things about this house seem to be that it has a sloping roof, lots of windows, and it was built in 1964, so it's possible they might be using the expression lightly.
This listing tries rather admirably to actually make the "once in a lifetime" case, but it ends up pretending that this is the only renovated old house with a yard in Chicago.
