• The present relative value is the current value of the house without the freehold, compared to the value with the freehold.
  
  For example, if the current market house price of the property without the lease is £80,000 and the new market value of the property with the freehold is £100,000, then the "relativity" is 80%.
  
  For property with less than 80 years on the lease, this is the key figure that affects marriage value. The higher this percentage, the cheaper it is to buy the freehold.
