Credit score does matter but they will lend on a per property basis out of your available LOC once they approve a line...again mostly based on your available cash and credit score.

People with good credit scores can even be denied.

@Steve Powers is correct that these were mostly originated as owner occupied loans.

I am seeing high 6s at 75 LTV with a 720+ score. 

What's your credit score looking like?

Real estate development that was planned around the factory’s original timeline may slow down.

Like maybe I could pull enough out from heloc on primary residence to pay off debt and then rent out my primary and use the extra cash to payoff heloc and then do another heloc once the original one is paid off.
