HELOC, DSCR, or Conventional?

[Luke Davis]

Newbie investor here looking to do my first actual investment purchase. Currently looking into doing a BRRR or a buy and hold in the FL market. My wife and I have our old primary home that we recently moved out of and are renting that has 150K+ in equity that we could tap into via HELOC to fund the down payment for our next purchase and cover the remainder with a DCSR or Conventional loan?

Curious what the more experienced folks here think is the best strategy given the current rate cuts happening. Having two open loans for the property is not ideal as that's double closing costs but maybe that is a fairly normal strategy?

Any advice is greatly appreciated!
