I have to put anything. I was told I would need at least 20%, the $ 100k for the property I in. If the seller is willing to finance 20% of banks would bail’m interested in would allow me to finance this property way? Or I could make a business plan for a bank for the purchase in full?

Nope. Banks not to lend for commercial real estate, unless you pay with your own substantial resources.
