Closing with IRS debt

[Brian Whetstone]

Good evening fellow investors! 

I have a loan closing 5/6 and have an issue my lender has brought to me. 
I am paid 1099 for sales and every year have a debt to pay to the lovely irs. 
sense the pre-qual from my lender I was advised that I would need to make at least 1 payment towards any irs bill before closing which I did. Differing the rest on short term plan to close on the duplex/rehab then pay in full. Now 4 days before closing I get a call that underwriting wants the whole debt paid in full (25k) at closing. 

I do have to full amount but it is currently in either stocks/crypto and probably can’t get into my bank before Friday. 
I kept only cash to close plus rehab cost in cash. 

What would be the best strategy or solution here? Has anyone dealt with this before. 

Thanks team
