I read that more as "baseline" being minimum acceptable or expected home size/location/amenities/fanciness, and what that equates to in dollars in the market the person is buying into. So the realtor wants to move the client's baseline up the scale so that they will only consider a home with more amenities, space, or fanciness than they originally thought they needed/wanted. Watching House Hunters shows this pretty clearly - oh, we must have dual vanity sinks, granite countertops, real hardwood, and 17 bedrooms with walk-in closes. No, I won't consider this plebian 1,500 square foot house with normal fixtures just because it's in my original price range. Time to stretch the budget! Ratcheting the baseline expectations back results in the same or more happiness for much, much less money.
