Best way to pull equity from a house

[Dar Shan]

Hi everyone, 

I am planning on making an offer on a multi-family property using the equity in my home. The home is paid off already. So, I wanted to know what would be the best way for me to take out money to pay for the house. I have been listening to the podcasts and have heard the term HELOC (home equity line of credit) thrown around. Is this the best way to pay for the other house? I'm basically trying to find a way to pay for the house with the lowest interest rate possible

If you have any other options for using my current home equity to pay, please let me know. 

Thanks for the help! 

Regards,
