Is Interest on a Rental Property HELOC Tax Deductible?

[Kyle Steiner]

I'm getting a HELOC on a rental property I own and I'm wondering if I'll be able to deduct the interest on my taxes. I plan to use the funds exclusively for the purchase of rental properties and/or flips and related investing activities. I read the answers to a similar question here: https://www.biggerpockets.com/forums/51/topics/436....  

However, that thread dealt with HELOCs on a primary residence, which is a different situation than the one I'm facing.  Any help with this question is appreciated.
