Borrow against or cash out of a brokerage account

[Bob Juengel]

I have a question for the more experienced investors! We are fairly new at real estate investing, having only 4 rental properties, doing one flip and one wholesale deal. We are wanting to increase our rental portfolio and do an occasional flip and some wholesaling.  In your opinion would it be better to take out cash from our brokerage account or to borrow against it? We can currently borrow from our account at 6.5%. If we cash out some of our stock, there would be capital gains taxes. Not sure if there is any tax advantages with borrowing? I realize this is probably not a straight foreword question but would like to hear some opinions.

Thank you for your time.
