A trust deed is a document used in 20 US states instead of a mortgage, specifying that an independent third party will hold property in trust until a loan from the lender to the borrower is fully repaid. Trust deed investments have a reputation for providing high yields with lesser risk than traditional investments, but investors are warned to avoid conflicts of interest, undervalued loans, and to ensure diversification. For safety, investors should use a neutral third party like a title company for closings and seek to be in first position when funding trust deed investments.
