HELOC Pay off after BRRRR?

[Paul Bizzaro]

I am new to investing in rental/investment properties and looking for some guidance. I am doing as much research as possible before I make a move but do have my eye on a property.

Here is my current situation....

I am currently looking into a HELOC to purchase a multi family, rehab property, & rent. Once property is rehabbed and renters are in I plan on a cash out refi on the multi family house so I can invest in more properties.

Here is my question...what to do with the money from the refi? Is it best to pay back the HELOC? How many times will a bank let an individual do a cash out refi?

Doesn't debt to income come into play with refinancing?
