One of the most common moving frauds, unrealistically low price estimates can be a sign that something is not quite right. As you can guess, the final price will have nothing to do with the initial "low-ball" estimate you received.
Fraudulent moving companies often use this move to hook unsuspected customers with promises that are never delivered. Rogue moving companies tend to give estimates over the phone and more often than not are simply too good to be true.
If a moving company performs a quick walk-through of the rooms and quotes you a low price without asking you any essential questions, then that suspicious behavior should tell you that you need to find yourself another moving company.
Never be fooled into paying hidden fees.
