Three aquaintances we know of have taken equity release and have regretted it.
Friends recently bought a house that was part owned by an equity release company and part owned by the estate of the former owner. The house sold for a lot under the market price, the equity release company got the bulk of the sale price and a very unhappy family got very little and little or no say over the agreed selling price. They actually stripped the house of all fittings and went to war with the E R company if that tells you anything.
