The simple solution is for you to change the title on these assets to you & your daughter as joint tenants with right of survivorship --- and also to change your rental agreement to provide for your daughter as a co-tenant. The problem is that by doing so, you give her access to the assets (and your housing) now, not just at your death.
Better would be for you to make a Will, naming her as your Personal Representative & sole beneficiary of your estate. That delays providing her access to your assets until your death. If the total value of your assets at death do not exceed $100,000 & if you then own no real property (such as a home), no probate should be required, and your assets should be able to be transferred to her simply & efficiently with a Small Estate Affidavit, which does not involve the Court.
