If you rent, you are simply paying off someone else’s mortgage for them.
Not this old chestnut again. No, when you rent you are paying for somewhere to live. Do you think that rents should be free? Or that people who actually want to rent rather than buy should be made to take out a mortgage because you know what’s better for them?
OP, remortgaging to clear debts usually costs more in the long run because you’re paying off the debt over a longer period. Say you add a credit card balance of £10k to a 25 year mortgage term. The headline mortgage rate may be lower but thanks to compound interest working in the lender’s favour, you end up paying loads more interest.
You might think, it’s worth it for short term relief but the extra interest you pay to the lender could have been used to pay towards a pension or savings.
That is why you see so many adverts - including those featuring the awful Carol Vorderman to make you think ‘oh yeah, she can do maths’ - exhorting people with debts to convert them into a loan secured on their homes at a lower headline rate. The lenders can’t lose: you keep on paying and paying, they more than double their money and if you default, they take the house.
I’d investigate a PP’s suggestion of shifting credit card balances on to 0% cards.
You say that you were ‘screwed over’ which suggests that this is debt arising from a business. Provided you can afford your current house and lifestyle under normal circumstances I’d stay put and consolidate the debt into a loan that isn’t secured on your house, that you can work towards paying off in as short a period as possible. Good luck.
