quicker and higher interest or slow and lower interest?

[Rigo V.]

I have a property I was hoping to BRRR. I purchased and rehabbed with a HML and I am currently looking to refinance. I have a lender who is not concerned about seasoning offering me 6.5% interest on a 30 yr fixed. I have a bank that wants to see 6 months seasoning but offering 4.5% interest.

My question is  do you sacrifice cashflow to be able to get your initial investment back quicker and invest again or do you wait the six months and maximize the cashflow?
