Mortgage rates on high down payments

[Dwight Sands]

I am currently stuck with a (somewhat) good problem. I have to spend a certain amount on 2 financed purchases that will be well over 25% down. I know there is generally a better rate to be had when putting down 25% vs 20% but what is typical on higher down payments, say between 25% and 50%? Does that sliding scale change significantly after 25% down?
