25% down for 2-4 unit properties?

[Dallas Easter]

I have been looking for a good local lender in my area and several of the banks are telling me that its 25% down for 2-4 unit properties. Is this bank specific or has the requirement to put down gone up? I've noticed a lot of people use 20% down in the examples they share as well as with the webinars I have watched on this site. Wondering if someone could give some insight to their personally experiences. Thanks
