disbursements payable by the plaintiffs. The order under review is the culmination of a motion by the defendants, pursuant to CPLR 5240, to vacate and set aside an execution sale conducted by the Sheriff of Rockland County on June 13, 1975. By order of reference dated May 3, 1976 a hearing was directed to determine the following issues: (1) whether intervenorappellant Frances Camardella was the agent of plaintiff Michael Fiala on the date of the sale; and (2) if it be so determined, what is the difference between the sales price and the fair and reasonable value of a certain bond as of June 13, 1975. Following the hearing, it was determined in the order under review dated March 15, 1978,
inter alia, that Frances Camardella was the agent of Michael Fiala on June 13, 1975 at the time she purchased the bond and mortgage in the face amount of $120,310.67 for the sum of $50, that the fair and reasonable value of the bond and mortgage at the time was $60,000, and that the difference between the sales price and the fair and reasonable value of the bond and mortgage is $59,950. The March 15, 1978 order directed the plaintiffs to file a satisfaction of a default judgment which had been entered against the defendants, directed that plaintiffs pay to defendants the sum of $17,929.82 with interest from June 13, 1975, which sum represents the amount collected by the plaintiffs from the defendants on the default judgment by levies prior to the sale of the bond and mortgage, and further directed the plaintiffs and Frances Camardella to pay the defendants the sum of $17,929.82 with interest from June 13, 1975, which sum represents the difference between the full amount of the default judgment and the value of the bond and mortgage, less the $50 paid thereon. We agree with the finding that Frances Camardella was the agent of Fiala on June 13, 1975 when she purchased the bond and mortgage, as it is fully supported by the record. The reference hearing record lacks, however, satisfactory evidence as to the value of the bond and mortgage as of the date of the Sheriff’s sale. The record discloses that (1) a bond and a mortgage in the amount of $120,310.67 were executed by Fiala on September 10, 1971 as a purchase money mortgage covering two parcels owned by defendants subject to two first mortgages that had a total existing balance due in September, 1971 of approximately $34,000; (2) Fiala subsequently sued the defendants and recovered a default judgment; (3) pending determination of an appeal from the default judgment, the bond and mortgage were filed in escrow with the County Clerk of Rockland County pursuant to an order of this court made upon defendants’ application to stay enforcement of the judgment pending appeal; (4) following the dismissal of defendants’ appeal for failure to prosecute, the Sheriff of Rockland County levied, pursuant to the default judgment, on bank accounts of the defendants, leaving an unpaid balance in the sum of $24,119.55; (5) a judgment of the Supreme Court, Rockland County, dated April 3, 1975, directed the sale of the bond and mortgage as a result of a proceeding brought by Fiala in further execution of his judgment; and (6) at the execution sale Frances Camardella purchased the bond and mortgage for the sum of $50. The record is unclear as to the basis upon which the fair and reasonable value of the bond and mortgage was determined. Assuming that the parties interpreted the order of reference which mentions only the bond to include the mortgage with the bond, the question becomes, what is the market value of the mortgage? This in turn depends in part, but not entirely, upon the market value of the land (see
Matter of New York Tit. & Mtge. Co., 277 NY 66 , 77). "In determining the value of mortgages as in the case of the premises themselves, there is no hard and fast rule. All reasonable factors should be considered and it then becomes a matter of the exercise of
