HELOC interest deductibility

[Teresia Sayler]

I understand with the new tax law that if you use a HELOC on your primary residence to purchase (possibly improve) investment/rental property, that the interest on that HELOC is deductible.

Will this interest be listed on the Rental property's Schedule E info (even though it is secured by your primary residence), or will it continue to be on the 1040 Sch A (Itemized deductions)?  If left on the Schedule A, will the total of this particular loan interest still need to contribute to exceeding the personal exemption (limits that have been raised) in order to be deducted?
