As you're scanning the real estate ads and listings, be wary of the phrase "Oak Brook area."
That's advertiser-speak for "a location that's perceived as so undesirable we'd prefer not to name it."
Be wary, but don't abruptly pass on the ad. Perhaps you're looking for a low-priced alternative to Oak Brook with easy access to its employment corridors, shopping and dining. If that's the case, Oak Brook area might suit you well.
