David and Victoria Beckham are selling their English home known as Beckingham Palace.

They're asking $15 million, with some serious strings attached.

They want to sell only to a private buyer instead of a developer who might cash in on their name and split the estate into luxury apartments, a source told the Daily Mail.

"They know there aren't lots of individuals looking for houses of this size, and developers would jump at the chance to turn it into smaller flats, which would have added value because of the Beckham connection," the source said.
