JVs with private lenders

[Matt B.]

I read in an article recently that a lot of private lenders have flexible terms and many will even do JVs

from my own experience of speaking with private and HM lenders this hasn't been the case. 

have any more experienced or knowledgeable people here in BP ever done a JV with lenders? is it a common service in the lending world? I'd like to learn more about it if possible
