Interest on HELOC deductible if used for investment down payment

[Praveen Kumar]

Now that the interest on a HELOC isn't deductible on a primary anymore, I was wondering if it could be deducted as a rental expense if used as a down payment? I'm about to make an offer on a single family home using funds from my HELOC and it will take me some time to pay down the HELOC (higher rate than a conventional investment loan).
