In a nutshell this is the interest rate on a mortgage loan.
This was a government scheme that was discontinued in April 2001 that allowed you to claim tax relief on the interest you paid on your mortgage.
These are the fees charged by a solicitor or other qualified individual to carry out the legal work associated with buying a property.
These are the charges made on a loan, calculated as a percentage of the total amount that you borrowed on your mortgage.
When you have the freehold on a property this means that you solely own the property and the land it is situated on.
