Her agent, who we also found out represented the seller, replied with this...
"...actually the house is copper wired. It is not aluminum wired. Your inspector was wrong.
"I am now researching to see if the agent has an electrician's license , since he offered electrical advice."
Seriously...I don't know what the rules are there, but when agents "double dip" here, I'm fairly certain that they have to disclose that they are, first and foremost, representing the seller. Clearly your client's best interests are not being adequately represented. Can she retain a buyer's agent at this point in the transaction? (Added bonus of splitting the first agent's comission 
)
The rest is just hot air and I wouldn't lose any sleep over it.
