Thanks for your reply.
Well, there are lots of equity schemes out there, but you both need to make sure that this is the right thing for you to do. Yes, it will allow you to live more comfortably, but you have to bear in mind that although the standard interest rate is approx. 5%, all of these schemes are subject to "compound interest" which means that because you are not making any monthly repayments, you will be paying interest on the interest which is being accumulated. This has the effect that a £30,000 loan will mean there is approximately £80,000 outstanding after 10 years!!
You must also remember that if you were to take out a scheme the Lender views it as a lifetime loan, which is only repayable on your death or if you both went into a Nursing Home. So, the longer the loan remains, the higher the outstanding amount gets, but if you wished to repay it early, you are then penalised with a hefty early repayment charge of anything from £5 to £10,000.
I am not saying not to take out the loan, but you should speak to a specialist financial adviser before proceeding, and as long as you are aware of the hefty increase in the amount that becomes outstanding over the years (and your Daughter and any other children you have are aware that this will vastly reduce their inheritance), then at the end of the day, it is your house and you are free to do with it as you wish.
I hope this assists you.
