Refinancing in BRRR all CASH

[Jc Galang]

Hi everyone, first post. I've been lurking the BP community for a while and it's been exciting to learn from everyone. Thank you! 

This question has been asked multiple times in the forums and covered in some articles but I am still pretty confused. When REFINANCING a BRRR property bought with cash, is a seasoning period required? To my understanding, if all cash, then no seasoning is required. But, i've also read that regardless of initial investment (cash, conventional, HML/PML), a 6 to 1 year seasoning is required depending on the lender I am refinancing with.

I guess what I dont understand is, if bought with my own cash initially, why the seasoning? 

Hope it makes sense, and thanks in advance!
