Where to park my Heloc money till ready to invest?

[Rijm D.]

Getting a Heloc, hopefully around 120K. It's a fixed loan product, need to borrow full amount by end of Feb to take advantage of 10y at 4.49%. It being long term and fixed is perfect for what I intend to do with it, just dont want to be pressured to buy just because the money is costing me. I thought to at least put it in a 2 to 2.3% savings account to offset the costs. Dont want to gamble it and I intend to access it at 10k downs for low end properties. Any suggestions where to park it safely but accessible and at a good rate?
