Knowing how much equity release costs will be a key consideration for anyone thinking about taking out this kind of mortgage, and the core part of that will be the interest rate you're charged. This will vary according to your own individual circumstances – including your age and how much you're looking at releasing from your home – which is why you'll want to use an equity release calculator when discussing things with your provider.
You'll be required to pay fees for arranging the mortgage, too, much like with a residential mortgage, which can vary according to provider. You'll also have to pay valuation and legal fees, and advice fees are another cost.
However, it's only when you sell the home that the full costs will be realised, as it's only then that interest will have to be repaid. This is why getting the best possible interest rate is essential, and why you'll want to work with advisers and brokers to get the best deal.
