More HELOC questions

[Benjamin Nelson]

So I am taking a HELOC out on my primary residence to use as a downpayment on a 4 unit apartment house. The Loan for the house will be at a different bank than the one im taking a HELOC out from. After say a year or two and increase the rents, would I be able to go to a bank and refinance the value of the apartment house and pay off the HELOC thus freeing it up for use again?
