Home Equity Line Of Credit

I own a non-owner-occupied investment property and have been having a difficult time finding a lender that offers HELOCs on investment properties.

I'd like to leverage some of the equity I've built in the property to help fund my next investment. For those of you who have done this, who would you recommend reaching out to for a HELOC on a rental property?

If a HELOC isn't the best option, what other strategies or financing options would you recommend for accessing the equity without refinancing considering my interest rate is 2.5%

I’d especially appreciate recommendations for lenders or credit unions that are investor-friendly and actually lend on non-owner-occupied properties. Thanks!
