What is the longest reasonable for small commercial Multifamily?

[Tyler HOOD]

I am coming up on a balloon payment for an 8 plex with a value around 1mm. The bank  is pushing a 5 year term hard. With interest rates where they are, I would love a longer term. Any ideas on what I should reasonably expect/ask for? I shop banks relatively often but have been happy with this bank otherwise so I don't want to push if I can't find it anywhere else. TIA
