Refinance current home first then HELOC to purchase rental home?

[Brandon Combs]

I own my current home and have good amount of equity in it and with interest rate being so low it could really help me out with refinancing it and get a better debt to income ratio. But I am looking into getting a HELOC out for downpayment on my first rental property. Don't know if it's best to refinance my home then HELOC or just get dive in and get HELOC. Trying to find the best path moving forward.
