Pre-approval before selecting lender?

[Craig Cerny]

Numerous pod casts have indicated having pre-approval will show agent and perhaps lender your a serious contact as your using BP agent finder to establish a team. I don't yet know the lender I plan to establish a relationship with and frankly don't know the financial instruments I will ultimately leverage, does it make any sense to get a pre-approval now as I'm establishing a team? Note, a HELOC may also get setup to fund my deal and I'm not sure if getting one before pre-approval or vice versa would be a concern. Any thoughts?
