Seller Financing--Seller Wants Tax Returns

[Jake F.]

I'm looking to buy a multifamily property. Seller has agreed to owner finance but wants to know if they can see my last two years tax returns. Seems odd to me as opposed to asking for proof of funds for the down payment or doing a credit check. Is this normal? I know the bank would ask for it, but I've never considered asking for tax returns in the few notes I've created.
