For us, I am always up for moving and love house hacking, so we are using the personal home HELOC to make some improvements to the personal home to put an apartment in and rent it out.A family member paid off her home, put a 1st lien HELOC on it, planning to pay cash for a rental for speed and ease of transaction, refinance, then recycle the funds acting as her own "hard money" on BRRR projects.
