Queen Elizabeth II is expected to gift grandson Prince Harry and future granddaughter-in-law Meghan Markle one of her estate's as their wedding gift.
When Prince William and Kate Middleton wed in 2013, the Queen gave the newlywed couple Anmer Hall on the Norfolk estate.
The couple moved into their new home two years later, just before Prince George was born.
Royal expert Kelly Lynch said, 'Her Majesty gifted William and Kate Anmer Hall. I'm not certain how many other homes are on the Sandringham Estate but I wouldn't be surprised if one was gifted to Harry and Meghan. Especially given the fact that the royals spend Christmas at Sandringham.'
As Prince Harry and older brother Prince William are very close, Lynch believes the two will choose to live next to each other and have their children grow up together.
Lynch adds Her Majesty may gift the couple a home in Windsor as it's where the pair will tie the knot.
'I wouldn't rule out any available homes in Windsor, as that will be where Harry and Meghan will wed,' she said.
