Arthur Wilder falsified his earnings when applying for two mortgages worth more than £1m.
He claimed to be earning £300,000 a year, even though he had no accounts to back this figure up, and failed to declare a previous bankruptcy, a court was told.
Wilder claimed at the trial that two brokers had filled in the earnings details on application forms without his knowledge, according to the Grimsby Telegraph.
The advisers were also blamed by Wilder for forging some of his signatures and initials on paperwork for the mortgages.
He had first tried to secure a £1m mortgage from the Royal Bank of Scotland (RBS) for a stately home in a deal that fell through.
A year later in 2007 Wilder managed to secure a £1.4m remortgage on a property he owned near Scunthorpe, again using false information.
Wilder spent £630,000 of the mortgage, including splashing out on a yacht.
RBS repossessed the property after he failed to make his mortgage repayments.
But the false statements to the lender were only found out after a separate police licensing investigation into Wilder’s nightclubs.
He was then found guilty of trying to obtain money by deception and making false representations on both the mortgage applications by a unanimous jury verdict at Hull Crown Court.
According to the Grimsby Telegraph, Judge Mark Bury told Wilder: “You saw an opportunity to exploit the mortgage market and you did so but ultimately it all came crashing down around your head.”
