Multifamily in Garfield, NJ - seller financing - tax returns

[Mike A.]

Our lawyers are going back and forth on this and I wanted to get the forum's take. The seller is requesting to review the LLC's annual tax returns each year. I know, with banks this is usually done, this would be my first with seller financing requiring this. I'd rather not give my tax returns on my entire company to the seller. The are not a bank, just a group of four family members selling a 25 unit building.

What's everyone's take on this?
