HELOC no longer tax deductible?

[Amy Yarnall]

Note: I haven't figured out to search the forums, and I have a feeling this is redundant. If so, please educate me? 

Now for the question: in the new tax law, effective Jan 1, 2018, I understand changes have gone into effect regarding the ability to deduct the interest of HELOCs. Is this accurate? How does it affect rental property? 

We have a HELOC on our first property which we used to make the down payment on our second property (we have two total)
