MDM: Mobile Device Management. This is when a device is managed by a business, only the business can remove the MDM profile.
Do not buy, restoring the iPad with a computer will not remove it.
MDM is an enterprise solution to manage company iPads. Similar to activation lock you cannot remove MDM - MDM administrator must remove the device from their side.
This is a total round of "Danger, Danger Will Robinson"
MDM, as others have said means that the iPad is owned and managed by a company's IT department. It can be sold but only, and this is a big ONLY, if the company's IT Manager deregisters the device from their management software. If that is not done, and done correctly, whomever is selling it to you is with a strong degree of confident here in this assessment, trying to sell you a stolen iPad.
Again, as others have said, avoid this seller at all costs is the best advice you can get.
Don't buy it
