HARTFORD, Conn. -- Rap star 50 Cent claimed during the continuation of his lawsuit against a Bloomfield engineering firm on Wednesday that the firm gave him bad advice before he bought his Farmington mansion.

The rapper, whose real name is Curtis Jackson, bought the mansion from Mike Tyson in 2003 for $4.1 million. He said engineering firm BVH identified $2.5 million worth of problems during a home inspection.

As the trial continued in Hartford, Jackson's lawyer, Michael Feldman, called BVH Vice President Greg van Deusen to the witness stand and said the big issue is the company's claim that it was only hired to do a rough walk-around inspection.

"Point to me in the contract where it says that physical observation is limited to a walk-around visual inspection of the property? Those exact words were not used," said Michael Feldman, Jackson's attorney.

Jackson said Tuesday that he relied on BVH's report before buying the home.

But BVH said its estimate was only an educated guess.

"What we're trying to do is try to get as close to what we think the real number might be, given very limited information," van Deusen said.

Jackson's lawyers said inspectors never counted the mansion's windows before calculating the cost to replace them and never checked to see if the heating system worked, and that van Deusen admitted to not knowing exactly how the $10,000 estimate for repairing cracks in the house's 46,000 square feet of driveway was developed, though he said he did the work.

Judge Eliot Prescott asked how BVH's services compared to a traditional home inspection.

"They also make assumptions," van Deusen said. "I don't know that they necessarily check every single light switch and every single outlet in a house, for example."
