Line of credit versus refinancing

[Gina Nicolas]

Good evening all.  I m currently reading : Buy, Rehab, Rent, Refinance, Repeat by David Greene, having 3 properties with no mortgages, I am thinking about refinancing in order to get more properties. I have met with my banker 2 days ago to discuss my options to refinance when he asked me why refinancing and paying closing costs again instead of applying for a line a credit on the properties.

Refinancing or line of credit, which one would be best to get my cash out to acquire more properties as an investor?

Thank you
