New Delhi, Aug. 20 -- Prince Harry and Meghan Markle have said they intend to keep their Montecito mansion as they prepare to move their family back to Britain. However, speculation is growing in California's luxury real estate market that the couple could eventually sell the property.

A source in the Santa Barbara luxury property market told the New York Post there have "been rumblings" about a possible sale, adding that interest among brokers would be intense if the estate enters the market.

The potential sale could also be influenced by the substantial cost of maintaining the property. The New York Post reported that the former royal couple spends more than $600,000 a year on mortgage payments and property taxes alone.
