It’s a strategy that allows investors to acquire rental properties with little to no money out of pocket while building equity along the way.If you're considering using the BRRRR method to grow your real estate portfolio, here's everything you need to know about how it works, its benefits, and potential risks.What is the BRRRR Strategy?

Interesting idea, but I suspect that would create more problems than it is worth.Most of the leverage you have with a NNN lease is that you are working with a company, presumably one that makes money. 

Yes, You can buy and asset, fix it up and rent it out to make money without you physically having to work for the money. 

I’m currently working on a deal in Fort Lauderdale & actively looking for financing solutions like hard money or private lending.

If you wanted to fund a portion of the down payment would you suggest a hard money lender, personal loan, etc.?

Mistakes I see people make is they plan on living there a short time and over renovate the property where they will never get the money they put into it back. 

You can get a HELOC if there is equity in the property most likely, which there should be since you own it in cash, but you will just be decreasing your pay out and then may end up short in repair money, depending on how much it is worth.

Does this strategy utilizing HELOC really work on saving money and paying off mortgages much quicker?  

While I do maintain a relatively modest percentage of my assets in money market instruments, corporate debt funds, and high dividend stocks, I remain most comfortable with the investments I specialize in and know best.  

There's no current loan on it right now.Given that the investor is a family member (that's how I'm reading it), buying the LLC will "save" you money from buying the land yourself as there won't be any closing/transaction costs.
