Our Story
Nothing hidden. Nothing missed.
Property Portal 24 was built to prove that in real estate.
Listings processed through our pre-packaged standard consistently achieve near-zero post-inspection repair negotiations.
Our sellers support a 7-day contingency with confidence because everything is known, documented, and disclosed before day one.
Brian Maser's deep field experience across condo, single-family, and residential transactions is encoded into every step of the process.
Keith Muenze brings three decades of building systems that scale — now applied to a problem the industry has never solved technologically.
Our Mission
The real estate industry has operated the same way for decades. Listings go to market unprepared. Buyers make the most significant financial decisions of their lives with incomplete information. Agents (even the great ones) spend enormous energy managing chaos that should never have existed.
Every Top Producing agent already knows the Truth: the transaction is a pattern. The same process, the same steps, the same required information — every single listing, every single time. The best agents know this. They have built their own systems, their own checklists, their own disciplines. What they have never had is the technology to fully automate it, standardise it, and make it transparent to everyone — buyers, sellers, lenders, and agents alike.
Property Portal 24 was built to do exactly that. We deconstructed the listing and buying process from first principles. We worked alongside the strongest minds in the industry, not outside consultants without field experience and rebuilt the processes with technology at every layer. The result is a pre-packaged, fully verified, timestamp-certified property standard that eliminates the unknowns before they become problems.
What we Built
We did not theorize this from the outside. We tested it inside Brian Maser's brokerage, The Condo Experts, on real transactions with real clients. The process works for condominiums, single-family homes, and townhomes across residential real estate. It works because it is grounded in the actual pattern of the transaction — not a reimagination of it.
On the seller side, our listings go to market fully packaged: inspection reports completed, HOA certifications verified, preliminary title reviewed, disclosures properly prepared, and every document indexed and accessible. The property has a readiness rating and a timestamp. Nothing is missing. Nothing is a surprise.
On the buyer side, our buyers receive a complete intelligence report on every property they consider. They understand what they are buying, what the HOA's financial health looks like, what the inspection revealed and how it was addressed, and how the property is priced relative to the market. When they close, they close with clarity. They know exactly what they are taking ownership of and are prepared to own it — without surprises — for the next three to five years.
For agent teams, this process does something equally significant: it saves time, reduces liability, educates junior agents to operate at the highest level, and brings every member of a producing team into alignment around a single, consistent standard. The top 1% of agents in this industry care deeply about the outcomes of their clients. This platform is built for them — and for the clients who deserve that level of care.
The standard exists. The technology is proven. We'd love to have you on the journey.
What we believe
The transaction is a pattern.
The same process, the same steps, the same required information — every single listing, every single time. We automated the pattern so agents can focus on the people.
Sellers deserve to go to market ready.
Every listing should arrive with inspection reports completed, HOA certifications verified, preliminary title reviewed, disclosures prepared, and every document indexed. Nothing missing. Nothing a surprise.
Buyers deserve complete intelligence.
Our buyers receive a full report on every property they consider — HOA financial health, inspection findings, pricing context. When they close, they close with clarity.
Time is trust.
A 7-day due diligence window is only possible when everything is already known. We make that the standard, not the exception.
Great agents deserve great infrastructure.
This process saves time, reduces liability, educates junior agents, and brings every team member into alignment around one consistent standard.
Verified excellence.
Portal Verified isn't just a badge — it's a commitment to the highest standard of care, for every client, on every transaction.
The Founders
Property Portal 24 is the product of two careers converging at exactly the right moment.
"The top agents already know the process. We built the technology to make every agent (and every client) benefit from it."

Brian Maser
Co-Founder & Chief Domain Officer, PropertyPortal24
Brian Maser is a top-producing real estate operator and the domain architect behind PropertyPortal24. With over $1 billion in closed sales, 700+ transactions, and 600+ renovations managed, he has spent more than three decades operating at a high level within residential real estate—where execution, precision, and results matter.
As the founder of The Condo Experts, Brian built his reputation not only on production, but on his ability to systemize what actually drives successful outcomes inside complex transactions.
Through years of real-world execution, he developed a set of proprietary frameworks that have redefined how deals are prepared, presented, and closed:
- Pre-Packaged Condo Sale™ — organizes disclosures, HOA documents, inspections, and financials upfront to eliminate uncertainty
- Listing Summary™ — a clear, structured, decision-ready overview of the property
- Buyer Summary™ — a simplified breakdown of material facts, risks, and key considerations
These systems have been deployed across hundreds of transactions—consistently driving faster deal velocity, fewer renegotiations, tighter contingencies, stronger seller outcomes, and buyers who close with full clarity and confidence.
While refined in the highly complex condo space, these frameworks were always designed to scale across all residential transactions, including single-family homes.
PropertyPortal24 is the productization of this proven approach.
Built in partnership with Keith Muenze, the platform translates Brian’s real-world frameworks into scalable decision infrastructure—bringing structure to fragmented information and enabling agents, sellers, and buyers to operate with greater clarity, speed, and control.
Clarity wins deals. Structure scales businesses. Transparency builds trust.
Keith Muenze
Co-Founder & Chief Technology Officer, PropertyPortal24
Keith Muenze is a product and engineering leader who builds high-performance systems that simplify complex, high-stakes workflows at scale.
Prior to PropertyPortal24, he co-founded Kixie and helped scale it to over $21M in ARR as Head of Product and Technology. The platform processes more than 1.5 million calls per day, supports real-time SMS communication, and integrates across dozens of CRM systems—requiring precision, reliability, and continuous performance.
Earlier in his career, Keith held product leadership roles at Rent.com (an eBay company) and Dex One, where he built products designed to operate at scale in real-world environments.
PropertyPortal24 was built through Keith’s partnership with Brian Maser, where they identified a critical gap: real estate transactions involve massive amounts of information, but lack systems to organize, interpret, and deliver that information in a way people can actually use to make decisions.
Brian had already developed a proven framework—through the Pre-Packaged Condo Sale™, Listing Summary™, and Buyer Summary™ systems—that consistently delivered faster, cleaner, and more transparent transactions.
Keith is leading the build to scale that framework.
As CTO, he is responsible for architecture, product development, and execution—transforming fragmented transaction data into structured, decision-ready intelligence that accelerates deals, reduces friction across repairs and contingencies, and improves outcomes for agents and their clients.
Together, Brian and Keith are defining a new category: decision infrastructure for residential real estate transactions.
Complex systems should feel simple to the people who rely on them most.
