Ordered that the judgment is affirmed, with costs.
The trial court did not err in ordering specific performance of the parties' contract for the sale of real property. The testimony of the purchaser's attorney and the documentary evidence support the finding that the purchaser was at all times ready, willing and able to perform (see, Tucek v. Hoffman, 161 A.D.2d 588), and that the failure to close was due to the sellers' refusal. Any defense based upon the purchaser's alleged failure to appear at an October 30, 1984, closing was waived by the parties' subsequent negotiations (see, Levine v. Sarbello, 112 A.D.2d 197, 200-201, affd 67 N.Y.2d 780). Bracken, J.P., Harwood, Eiber and O'Brien, JJ., concur.
