Former solicitor Michael Lynn has been convicted of stealing almost €18 million from financial institutions in 2006 and 2007.
Lynn, who is 55 and from Millbrook Court, Redcross, Co Wicklow, had pleaded not guilty to 21 counts of theft amounting to almost €30m from seven financial institutions between October 2006 and April 2007.
The prosecution alleged Lynn took out multiple mortgages on the same properties from different financial institutions who did not know other banks were also providing finance.
The financial institutions involved are Bank of Ireland, National Irish Bank, Irish Life and Permanent, Ulster Bank, ACC Bank, Bank of Scotland Ireland, and Irish Nationwide Building Society (INBS).
Lynn claimed he had "off the books" agreements with the banks to use the loan money for his property developments abroad.
The jury found him guilty on ten of the 21 counts and told the judge they could not agree verdicts on the others. They spent a total of six and a half hours deliberating.
Lynn was remanded in custody pending a sentencing hearing in January.
Lynn first went on trial in spring 2022. But that jury could not agree on a verdict on any count. His evidence at that trial "stunned" the court the judge said as Lynn claimed he had permission to use the money to buy property abroad and that the banks were fully aware of what he was doing.
His trial this time was shorter but Mr Lynn again gave evidence in his defence.

The prosecution alleged Mr Lynn was a greedy risk taker who lived for the next big deal and was gambling that the jury might accept his version of events.
Prosecution lawyers told the jury it was "implausible" that seven financial institutions across the length and breadth of the country were "in cahoots" with Mr Lynn in such a unique way.
Lawyers for the defence said the evidence showed the banks were aware of the purpose of Mr Lynn's borrowings and that one institution - Irish Nationwide - had a profit share agreement with him.
Judge Martin Nolan told the jurors if they believed Mr Lynn had the banks' permission to use the monies in the way he did, they must acquit him. To convict him, he said they had to be satisfied beyond reasonable doubt that he stole the money by deceiving the lenders.
Mr Lynn spent four and a half years in a Brazilian prison before being extradited to face charges here.
Lawyers for the prosecution said the gardaí would be objecting to Mr Lynn being released on bail. Lawyers for Lynn said he had gone through two trials here and had observed all his bail conditions.
Judge Martin Nolan said he was aware of the time Lynn had already spent in jail in Brazil, but he said there was a chance the court could extend that time. The judge said it was not appropriate to grant bail but he would deal with the matter as early as possible next month.
He remanded Lynn in custody until 15 January.
