It is depressing, but it is reality and saying you won't return to this thread, you are obviously well off enough not to have to! Lucky you .....
I am currently in a situation where I cannot afford to live where I do purely because my eldest daughter has returned home to live with me .... so it will be a case of her replacing my lost income, or I will have to up sticks and downsize by moving back to my roots to become mortgage free - bizarrely I will actually be able to upsize as the property prices are vastly different. I have a mortgage with no insurance - it used to be law, but not now I don't think. Equity release is not for me, but if you have no children or your children do not need an inheritance (which would just be the value of my house anyway) then Equity Release is a great idea, spend it whilst you can! Think eventually it won't be allowed as essentially you are giving away what would be used for your care costs should you need them, so get in there before they stop it!
Places like Age UK, Stepchange, Shelter, CAB will all be able to advise you on what to do - they will do an income and expenditure form with you and ask you about what your house is worth etc - I used Shelter and they were great! Getting life insurance now will cost you an absolute fortune, probably better doing funeral plans instead?? There are definitely options out there, you just need some advice as to how to find them - good luck! xx
