Best way to borrow against et held in trust for 10 years+ ?

I was left a part of a trust through a deceased estate and I won't have access to it for 10+ years. Surely the ets allocated to me in that trust can be borrowed against like any other et. I want to know what the best way and the best place is to go to borrow against it for either a house, or for some cash flow etc and whether repayments are required or a lump sum is payable once the trust is available.
