Commercial real estate refinancing question

[Mengzhu Rolff]

Hi guys, I'm a newbie for commercial real estate investment,I have a question about refinancing the property. I didn't have much money to buy this commercial apartment building, so I used HELOC as down payment to bought this property, and the rest I took mortgage. For BRRRR method, how do I refinance the property and get some money back to invest on more properties? Do I have to pay off HELOC and mortgage first? What the refinance can really help if I have HELOC and mortgage? Is there a smart way to get rid of HELOC? Thank you!
