Do you typically give a profit split to your PML?

[Clarence Browne]

Everywhere I read about PML, the "TYPICAL" deal is described as 8-12% interest (I've seen 6-15% as well) with nothing being mentioned about a profit split.  I do see instances where joint ventures may be up to 50/50 profit split but this is always discussed as expensive and out of the norm terms that you want to get away from as quickly as possible.  Is there typically a profit split with private money lenders?  I want to be fair with my lenders, but I also want to be clear on whether or not I'm paying more or less than the norm.
