There is no such thing as unsecured debt if you are a house owner.
The sooner unsuspecting borrowers realise the better!

This change has come about through the Charging Orders (Orders For Sale: Financial Thresholds) Regulations 2012

These new regulations came into force on 6th April 2013

Make no mistake that creditors WILL put the unsecured debts as a charge, and usually this will be against your house.
There's a lot of pressures can be implemented to force payments such as the threat (real or otherwise) of bankruptcy (which still remains at a debt of £750)
or even applications to the courts to force sale of the home

These regulations are a 'green light' for creditors to apply unsecured debts such as payday loans, credit or store cards etc against debtor’s homes with
only a minimum debt threshold of £1,000
