Rather use the numbers as your guide, be disciplined and do not letting emotions get the better of you.

If those people are young (and presumably have time to weather an investment going bad), and are disciplined, then I'd say yes, go ahead and HELOC to get your foot in the investment door. 

@Khayla C. you need the financial discipline to save up some cash.

The discipline of the Marines, with a college degree in finance, a real estate license, and a desire to learn might just be the perfect combination.

Are you disciplined?  

I think a major portion is many people do not have the time, discipline or budgeting skills to continue down the path and picking up deals.

You sound like you are very disciplined with your money, if you can keep most of it in reserves and acquire properties below value and build equity toward future investing, I think that's a good way to position yourself for bigger things down the road.

You need to operate as separate business to maintain corporate veil for the asset protection which requires lots of discipline.

But I'm disciplined enough not to make a dumb move and break my lease and possibly put me in a position to mess things up.

She didn't know how to operate them not had the discipline.
