The mortgage

A mortgage operates to collateralize real property by means of lien or through conditional conveyance of title, depending upon jurisdiction. A mortgage creates a security interest in realty created by a written instrument (traditionally a deed) that either conveys legal title (according to the "title theory of mortgages") or hypothecates title by way of a nonpossessory lien (according to the "lien theory of mortgages") to a lender for the performance under the terms of a mortgage note. In slightly less than half of states, a mortgage creates a lien on the title to the mortgaged property. Foreclosure of that lien almost always requires a judicial proceeding declaring the debt to be due and in default and ordering a sale of the property to pay the debt. Many mortgages contain a power of sale clause, also known as nonjudicial foreclosure clause, making them equivalent to a deed of trust. Most "mortgages" in California are actually deeds of trust. The effective difference is that the foreclosure process can be much faster for a deed of trust than for a mortgage, on the order of 3 months rather than a year. Because this foreclosure does not require actions by the court, the transaction costs can be quite a bit less.
