Can I deduct Interest on HELOC secured by a rental property?

[Daniel Eliav]

I got a HELOC on a rental property. The property was not used for personal purposes in 2019. I used 100% of the money for home improvements on my primary residence. Can I deduct the interest paid on the HELOC from my W2 income? Similar to how one would do so for their primary residence? Seems like the answer is no, but I have seen some posts about $100k limits on something like this, but not sure what thats about.
