Take maximum refinance amount Brrrr?

[Robin Casper]

I am trying to decide if I should take out the maximum amount I'm able to when I refinance a BRRRR deal. This is the scenario on the SFH...

Purchase price: 50k

Rehab/ closing costs: 10k

ARV: 100k

My bank will give me a commercial loan with 80% LTV so potentially a loan for 80k. That leaves me with 20k extra that I could pull out of the deal on top of getting my original 60 back. I plan to rent this house out for $1200/month. Expected cash flow if I take the full 80k would be $300. If I only took my original 60k out my cash flow would be more like $500. My thoughts are that If I took the additional 20k that It's cheap, low interest money that I could use to buy the next deal. Would you choose to pull out just the original 60k OR pull out as much as possible?
