I need a bank/lender that offers 15% down with a 20 year mort

[Jeff Chapz]

Hello, I found an opportunity to purchase two 4 plexes from one owner. My mentor heard of a person who purchased a 4 plex in the past with 15% down for 20 years.

Can someone tell me of a bank in Austin, TX that will lend under those terms?

I thank you in advance.

Jeff.
