The story behind 98 Doors

Built by an international entrepreneur who saw what aviation professionals needed — and built the vehicle to deliver it.

I didn't build 98 Doors for pilots. I built it because of them.

I'm an international business developer with roots in Miami, a Rollins College education in international business, and time spent studying commerce in Shanghai. Over the past 14+ years, I've built businesses across tourism, marketing, finance analytics, and real estate — from ecotourism kayak operations in Florida and the Outer Banks to real estate syndications across four countries. I've always been drawn to industries and communities that most people overlook.

The aviation community found me. I was doing short-term rental consulting and building out our Florida and OBX markets when I started noticing a pattern in the investors who needed our help most: airline pilots, first officers, cabin crew, aviation executives. They had the income. They had the discipline — you don't land a 737 without serious attention to detail. And they had a massive problem: their schedules made active real estate management genuinely impossible. Two AM calls from tenants? Not when you're on a layover in Tokyo. Managing a renovation from the flight deck? Not happening.

What I saw was a gap. The platforms that existed were either built for active investors with time on their hands, or institutional players with minimums that excluded most aviation professionals. Nobody was speaking to the captain who wanted institutional-grade access, full transparency, zero management burden, and a platform that understood their world. So I built it. 98 Doors is that platform — and Property Gurus is the operating team that executes every deal. You bring the capital. We fly the deal.

My background — Rollins College, Shanghai Jiao Tong University, business development across the Americas and Asia — means we don't think about real estate as a local game. Our markets span Florida, the Outer Banks, Nashville, and Lima, Peru. Our team speaks English, Spanish, Portuguese, and Mandarin. When we say we serve an international investor community, we mean it. And when we say aviation professionals are our niche, we mean that too — not as a marketing tagline, but because we understand what their financial life looks like and we've designed every part of this platform around it.

“The aviation community gave me one of the clearest briefs I've ever received from a market: high income, high discipline, zero time for landlording. My job was to build the answer.”

— Mario Simauchi, Founder & Managing Partner, 98 Doors

Three principles we never compromise

Every number, visible

Live portfolio dashboards, quarterly letters, real-time distributions. Our investors are professionals who read instruments for a living — they deserve the same level of data clarity in their investments.

We own what we offer

Every deal reaches our partners only after we've underwritten it as if our own capital were at stake — because it is. GP skin in the game is not a bonus; it's the standard.

We pass on most deals

The deals we don't do protect our partners as much as the ones we do. Cash-flow positive from day one, clear exit liquidity, and stress-tested downside scenarios are non-negotiables in every underwrite.

The playbook we built on

The principles that shaped our approach

98 Doors was built by synthesizing the best thinking from a generation of real estate operators. Here's the intellectual foundation.

Brandon Turner

Founder, Open Door Capital · Former host, BiggerPockets Podcast

Starting from a $20K house flip that funded his wedding, Brandon Turner built one of the most respected passive real estate investment firms in the country. As the former co-host of the BiggerPockets Podcast — the most downloaded real estate show in history with over 100 million downloads — and author of books that have sold over one million copies, Turner popularized strategies like house hacking, seller financing, and the BRRRR method before founding Open Door Capital, which manages nearly $1 billion in multifamily, mobile home parks, and self-storage assets.

Strategy connection: Brandon's conviction that passive investors deserve institutional-quality deal access — not landlord headaches — is foundational to the 98 Doors model. His documentation of the BRRRR strategy directly informs how Property Gurus approaches value-add acquisitions in our portfolio.

Ken McElroy

Co-Founder & CEO, MC Companies · Rich Dad Real Estate Advisor

Ken McElroy began his real estate career with a single condo purchase during college and built it into a $2 billion+ national multifamily portfolio spanning 9,000+ units across Arizona, Texas, and Oklahoma through MC Companies. As Robert Kiyosaki's Real Estate Advisor and author of the bestselling 'ABCs of Real Estate Investing' series in the Rich Dad Advisor library, McElroy has spent three decades teaching investors how to analyze cash flow, leverage debt intelligently, and build portfolios that survive market cycles. His philosophy: disciplined underwriting and operational excellence beat market timing every time.

Strategy connection: Ken's cash flow-first underwriting philosophy — and his insistence that every deal must perform even in a down market — is the exact framework Property Gurus uses to stress-test every position before it reaches 98 Doors partners. His DSCR floor methodology is built into our underwriting checklist.

Pace Morby

Founder, SubTo Community · Host, A&E's Triple Digit Flip

Pace Morby turned a contracting background into a $450 million real estate portfolio — without conventional bank financing. As the pioneer of the 'Subject-To' and Gator Method creative financing strategies, Morby has completed over 2,100 acquisitions using seller financing, subject-to deals, and other non-traditional approaches that allow investors to control properties with minimal upfront capital. His SubTo community has trained tens of thousands of investors worldwide, and his A&E series 'Triple Digit Flip' brought creative real estate to mainstream television. Morby's Wall Street Journal bestselling book further codified his systematic approach to deal acquisition.

Strategy connection: Pace's creative financing toolkit — particularly seller financing and subject-to acquisitions — directly expands the deal universe that Property Gurus can source for the 98 Doors pipeline. Off-market acquisitions using creative structures are a significant portion of how we access deals that never hit the MLS.

Operator's edge

Mario's kayaking operations in Rainbow Springs/Dunnellon and the Outer Banks gave him firsthand market knowledge of two of Property Gurus' most active real estate markets — years before most investors were paying attention to them.

Two brands. One wealth engine.

Property Gurus is the licensed brokerage and operating team — sourcing deals, executing acquisitions, managing assets, and handling every operational detail across all four markets. 98 Doors is the capital vehicle — the structure through which silent partners gain access to Property Gurus' deal flow without taking on any of the operational burden.

Property Gurus

The operating engine

Brokerage, acquisitions, asset management, and on-the-ground execution across Florida, OBX, Nashville, and Lima.

98 Doors

The capital vehicle

Structured access for accredited silent partners. Transparent reporting, institutional underwriting, zero management obligation.

Why aviation? Because we saw what no one else was building.

Mario's background in international business and STR operations gave him a clear view into which investor communities were being underserved. Aviation professionals — pilots, crew, aviation executives — had high incomes, high financial discipline, and schedules that made active property management genuinely impossible. 98 Doors was designed from that constraint: institutional access, zero management, full transparency.
