A: The best way to buy a house is to get pre-qualified, Ms. Anderson. B: Why is that, Mr. Williams? A: By pre-qualifying, you know beforehand which house you can buy. B: I thought I would look at houses first. A: That's okay too, but you may be wasting your time. B: How so, Mr. Williams? A: You may find a house you really like, but can't afford it. B: Well, that's when I'll negotiate with the seller. A: Yes, that's true, but by pre-qualifying, you'll save time, and effort. B: How is that? A: You will be able to select a home you know you can afford. B: Okay. Then we'll try it your way.
