BRRR method

[James Wheelock]

So I have been reading up on this whole BRRR method of investing, and hearing Brandon talk about it on podcasts. Say you do everything correctly and approach a refi. Do you at that point need to have a down payment to receive a loan from the bank, or no since you essentially have equity in the property... And also, say you have a great deal of equity in the property. Will the bank allow you a "heloc" as well. During the same transaction??
