Building financing - Where are the best conditions available?

My husband and I are planning to build or buy a house next year. And the first point, which of course needs to be discussed, is the construction financing. Since we don’t know anything about the matter at all, we wondered if maybe you could help us? Surely someone among you house builders can give us some good tips on the subject :) What do you think, where are the best conditions right now? What should be considered? How should one proceed best? I thank you already for your answers! :)
