In Arizona when you purchase a home you typically sign a Promissory Note and Deed of Trust.  The Deed of Trust is the security instrument that remains intact until the loan is paid in full.  The Deed of Trust allows a trustee to step in and exercise the power sale (called the Trustee Sale) if you default on your loan obligation or breach the terms of the promissory note in another way.  Arizona law states that the trustee sale shall not occur before the ninety-first day after the date of the recording of the notice of sale.  So practically speaking, at minimum, you have 91 days from the time the trustee files the notice of sale.  Realistically speaking the time from missed payment to trustee sale is much longer than that.  It is important to note that you may still bring the loan current up until the trustee sale.
