How long will a bank finance a mobile home for?

I'm trying to buy a 2006 fleetwood trailer house and i need to know how long banks usually finance so I can figure out payments. I also need to know what interest precentage they charge. I live in Oklahoma dont know if that makes a difference or not
Update: We arent lookin for one to last 30 years, 5 maybe 10 years at the most. and i already own the land free and clear
