I think we would all prefer this Greta, but HOW would you go about doing
it?
I would start keeping a spending diary as a priority to track down all expenditure, then cut down to the bone, looking for ways to enjoy life that are free or very low cost - like walks in the park, rather than cinema trips etc. Would also look for ways to make extra money, rent a room that you suggested is a good idea, or taking in foreign students over the summer. I would concentrate on paying down debts, starting with the highest interest rate, possibly putting the mortgage on interest only for a while, to generate extra cash towards clearing unsecured debt.
I thinks it's more viable for OP to (eventually) sort out their finances than selling the house, because some people just don't seem able to SAVE (for themselves). It's one thing to make DEBT repayments, as this has got to be done, but, once debt is repaid, they'll start running it up again, rather than saving for themselves.
To me the sale of their house to pay off the loans seems rather like consolidating the loans, which didn't work for them - they consolidated, then run up more debts, finding themselves in the present situation. If they sell the house and pay off debts, my worry is, rather than saving hard, they'll start spending hard and maybe even run up more debts
I think OP's most serious problem is their financial attitude and that has got to change NOW, not relying on quick fix solutions like selling the house or consolidating again.
Besides, OP's estimate of the value of their house may well be too optimistic, so the solution of sell the house and pay off all debts may simply not be available to them.
