Equity Release - can I buy back the equity?

Hello All

My Great Aunt and Uncle have got into an equity release programme.

I woould like to purchase the property after their death and wondered could I purchase the equity release part now.

They are fully aware of my idea and we're currently waiting for the company to get back to us.

Just wondered is it possible for me to do this and also any idea on what the cost would be?

I'm guessing they have @£40,000 remaining in equity in the property.

Thanks

Shazzy
