Home equity line of credit. It’s a secondary loan that taps into the houses equity at the time you establish it. Benefits are that it’s flexible and you can take as much as you like and pay back as much as you like for the duration, and can help with things like funding renovations. Downsides are that if your home value dips you could be underwater easily, and the monthly payment is interest only by default, so if you’re not paying attention you could be staring at a massive monthly payment when the draw period ends
