He only agreed to help the young agent buy the homes because he'd been asked, and because of the pair's shared Indian culture.
Grewal earlier told Goyal's lawyer Tim Rea he had no interest in either property and had not sought finance on them as he "never intended" to develop the neighbouring sites.
He later alerted the vendors to the alleged scheme after a falling out with Goyal. However, the tribunal learned of a new development in the case today.
Investigators contacted Grewal's lawyer to check whether the developer had sought finance on either of the Grassways Ave properties.
Prosecutor Michael Hodge said documents were received today from Westpac relating to an approved mortgage application by Grewal for one of the properties.
Hodge said the documents were "relevant evidence" given that Grewal had previously told the tribunal "that he had no interest".
"What we now know is he was actually approved finance four days in advance of the deed of nomination.
"It does raise the question or possibility at least of further questions to Mr Grewal."
Rea said the new information was "entirely inconsistent" with the evidence given under oath by Grewal.
"Mr Goyal's evidence is that he had been told by Mr Grewal that he had been approved finance for 11 Grassways but the problem was he couldn't get finance for both properties and without the two together that development wouldn't work".
That explanation made perfect sense in light of the Westpac financing documents, Rea said. Goyal was also quizzed by tribunal members today, who asked why the rookie agent had not sought advice from his Papatoetoe office branch manager when purchasing the properties he'd just sold as a nominee.
They also questioned why Goyal had not advised his manager that he had lent $130,000 to Grewal to cover the deposits. Goyal told the tribunal it was common to loan large sums of money to friends in Indian culture without any form of documentation.
He'd once borrowed $100,000 from his builder before loaning the builder $200,000 at a later date.
"That's very common for us."
The hearing has been adjourned for final submissions.
