About Mack

MacKinley "Mack" Justin, J.D., G.R.I.
I’m Mack Justin—real estate attorney, commercial broker, investor, and the mind behind The Mustang Lawyer.
I own, manage, and operate Justin Florida Law, Justin Florida Realty, and the Justin Florida Investor Summit (JFIS)—three lanes of one mission: helping people move smarter through real estate.
This blog is where sharp logic meets real talk. I built The Stang Blog as a space to unpack the legal, business, and personal sides of real estate—without the fluff, the clickbait, or the sales pitch. You won’t find recycled guru advice here. Just real insight from someone who lives it every day—in court, at closings, and on the streets where deals actually happen.
By day, I’m helping clients close, protect, or fight for their properties. By night, I’m reflecting on what it all means—legally, strategically, and sometimes philosophically. This is where I pull back the curtain, break it down, and share what matters.
Whether you're an investor, a fellow attorney, or someone just trying to make sense of the real estate world—welcome.
This is The Stang Blog.
Where Property Meets Perspective.

About
Justin Florida Investor Summit (JFIS)
Welcome to JFIS — Where Deals Meet Capital and Experience.
This isn’t a seminar. It’s a summit. A space built for serious real estate investors, deal-makers, and capital partners who want more than recycled advice and overpriced courses.
Founded by real estate attorney and broker Mack Justin, JFIS exists to connect the people who do with the people who fund. We bring investors, operators, and professionals together around one thing: real deals. Whether it’s your first flip, a complex commercial play, or a joint venture in the making—JFIS is where strategy gets sharpened, and execution gets done.
No fluff. No funnels. Just opportunities, partnerships, and real estate that works.
We don’t sell courses—we share the experience.
You bring the deal. We bring the blueprint. We split the win.
