Placing A Charge on Siblings Property

[Tingly]

Good Morning
My elderly brother is purchasing a bungalow.
I am 18 years younger than him.
He is looking at equity release after the purchase.
As some of the terms are restrictive and have penalties,I wondered if I could do a loan on the same basis as the lifetime mortgage, and put a charge on the property in the same way. (I.e. compound interest, payable when property is sold , give him the right of occupancy for life in case I predecease etc etc)
I wondered what the tax implications to me may be when the time comes to retrieve the money?

Thankyou

If it's compound interest you will pay tax on the interest when received. If that is only when the mortgage is redeemed, then the whole of the interest could be taxable at that time.
