Freehold
The legal right to hold land/property as the absolute outright owner, free of payment or any other duty owed to another party.
As a freeholder, you can then offer to rent your land/property to parties with whom you'll have a legal agreement. In other words, you may create leaseholders.
Most houses are sold as freehold properties but most flats are sold on a leasehold basis.
Get professional help from a qualified independent mortgage advisor and see how much you could save on your mortgage payments. There's no obligation, just plain good advice.
