Difference between Bridge Loan and Hard Money

[Pope Lake]

Hi BP! 

I'm looking to use the BRRRR strategy, and I'm trying to figure out: what is the difference between a Bridge Loan and Hard Money?

Ideally, I want to have cash to purchase a property upfront and do the rehab, wait for the seasoning period, then refinance into a traditional loan. Would a Bridge Loan or Hard Money make the most sense for this? What other financing strategies have you used for BRRRR?
