In an action by a loan broker for commissions against a client who had refused to complete a loan after a lender had been secured, evidence that the client had sold the property to supply him with the needed funds, is admissible as bearing on the credibility of his testimony that he had refused the loan because an existing mortgage could not be paid off before maturity. Payne v. Williams, 178 N. Y. 589, 70 N. E. 1104.
