The mortgagor and the mortgagee of real property consisting of less than ten acres in size may agree and provide in the mortgage instrument that the period of redemption after sale on foreclosure of said mortgage as set forth in section 628.3 be reduced to six months, provided the mortgagee waives in the foreclosure action any rights to a deficiency judgment against the mortgagor which might arise out of the foreclosure proceedings. In such event the debtor will, in the meantime, be entitled to the possession of said real property; and if such redemption period is so reduced, for the first three months after sale such right of redemption shall be exclusive to the debtor, and the time periods in sections 628.5, 628.15, and 628.16, shall be reduced to four months.
