Answer:
A rose is a rose...
Reg C, HMDA, doesn't define a bridge loan. It uses that term to define "temporary financing." Essentially a bridge loan is one loan in a series of loans that will result in longer term financing. Hence, HMDA's use of the term to define a temporary loan.
I have heard of bridge loans that meet the definition above being secured by either one, or both, of the properties. The security doesn't define the purpose, in this case.
