A home reversion plan involves you using just a part of your home's market value, say 40%, to raise money. There is no interest to pay during the plan, but when it ends, the lender is entitled to 40% of your home’s then current value. The value of your home is likely to have increased by that point of course and this means that your family will be able to inherit 60% of what your property is worth, minus any sales costs or inheritance tax that would be due.
The downside of this is that you will not be able to raise as much money as if you used all of your home for equity release.
