Seller Won't Provide Financials

[Brian Kennedy]

Trying to purchase a 12 unit but the owner says he can't give me the Financials because they are in his tax forms and it will cost $500 for his CPA to produce the data.

Shouldn't the the books be separate from his personal return? I know the LLC is a pass through but to keep the corporate veil in place there should be a separation between personal and business records.

Is this a common predicament? 

P.S. The seller says I could pay the $500 if I want the data.
