I think people are being unnecessarily damning on equity release.
Products now are far more variable. If you can afford to pay interest, you can get equity release plans where you pay the interest so that only the capital is repayable on death, you can get short term interest only mortgages that are repaid if you downsize and you can borrow a larger sum than you actually need but draw the money out only as and when you need it and interest only accrues on how much is drawn.
A wealthy friend has used equity release to reduce the inheritance tax on her estate. She is paying the interest and the money she has taken out has enabled two much less well-off younger relatives to move from poor quality rented accommodation while their families are young, rather than bring their children up in poor accommodation, only to inherit money after they have left home.
Similarly someone else has equity release on a large sum so that she can maintain her house but only draws it down as and when she needs it. She is currently accruing very little interest as she has, so far, taken out very little.
We are currently considering an interest only equity release mortgage to finance an extension, the mortgage will be repaid when we move house or die.
