Freehold properties are those properties where the owner of the land also owns any houses or structures on that land. Freehold differs from leasehold properties in this respect. For this reason many people opt for freehold rather than leasehold properties.
These properties can be given on rent by the owners, if they so desire. They do not have to ask the permission of anyone else to rent out the land or the buildings. They will simply have to find a tenant and then settle with them for the rent of the freehold properties. They can rent out the whole property or parts of the property.
Freehold properties must be selected with caution however, as purchasing freehold means you're solely responsible for any upkeep. The only limitations on what the owner can legally do with a freehold property are legal and planning restrictions. The vast majority of buyers will look for a freehold property rather than leasehold.
