An indictment of Quincy real estate auctioneer Daniel Flynn III cites fraudulent transactions involving a Quincy nursing home turned condominium development as part of an alleged scheme that began in 2007 and continued as recently as August.

A federal grand jury handed down seven counts of wire fraud and two counts of mail fraud against Flynn in U.S. District Court in Boston on Wednesday. The indictment cites nine victims who gave Flynn investments ranging from $225,000 to $750,000. In some cases, Flynn allegedly used the money to pay back previous investors in his real estate ventures.

In April 2005, Flynn acquired a nursing home at 86 Greenleaf St. in Quincy for $995,000 and converted it into a nine-unit condo complex.

In 2007, Flynn formed a real estate investment fund, DJF Real Estate Opportunity Fund 1, and raised over $6.3 million from 26 partners, touting his insider’s knowledge to identify distressed properties that could be resold for a profit.

Flynn is accused of fabricating statements on the fund’s assets and performance from April 2010 and April 2012. The documents included allegedly forged promissory notes totaling $2.3 million.

Flynn allegedly used $2.2 million from the real estate fund to buy the 86 Greenleaf property in July 2008.

The indictment also cites a property on Arbroth Street in Dorchester, which Flynn allegedly sold on behalf of a now-deceased investor in March 2012 but failed to return the proceeds.

Flynn, 52, had an initial appearance last month and is next due to appear in court Oct. 2.
