The idea that you can sell your home and rent it back might seem like a strange concept the first time you encounter it. The concept is well used in the UK by people who wants to escape the burden of mortgage and personal loan payments, but would continue to live in their house.
In business many companies choose to sell their premises every year and rent it back from a landlord. They do this to release cash for investment or to help their cashflow situation. For UK homeowners the reasons might be the same - you can sell to rent back to help your cashflow, pay your debts or create a pool of cash for investments.
