I echo the others: talk to an attorney. You may be able to have the house sold after your death, with half the sales price given to your son and half set up in a protected trust or other account which is a legal possession for your daughter. You may also be able to establish who makes decisions regarding her care after you're gone, who manages her financial affairs, and who makes medical decisions on her behalf. If you don't set that up, the state may put itself in charge.
