What's the difference between an instant estimate and a consultant estimate?

• Instant estimate: For homes of 20 pyeong or smaller, enter your belongings and conditions to see prices by date right away, and you can book and pay on the spot. The pay-now discount is also only available with the instant estimate.
• Consultant estimate: You go over the conditions with a consultant by phone to get an estimate. It's a good choice when you have unusual items or would rather explain things yourself.

Homes of 21 pyeong or larger submit a short request instead of getting an instant price (Estimates for larger homes).
