Refinance out loans on rental property

[Jay Mersfelder]

In middle of refinancing out on my rental property and lender is questioning a deposit of 3,000 from old work truck that I sold for cash. I've sent bill of sale and insurance being cancelled on the truck and even Screenshoted the market place add with the texted from person that bought the truck.. My lender keeps mentioning some Patriot act 2001. Just wondering if anyone else has had this problem before.
