ABOUT US
ABOUT MARINELAND CO-HOST
Marineland Co-Host is a locally owned and operated short-term rental management company built for owners who want their properties run like investments—not treated like units.
We live in the neighborhood—often just a golf cart ride away. That local presence allows us to stay hands-on, responsive, and closely connected to both properties and guests.
LOCAL FOCUS. PROVEN RESULTS
We own and operate our own short-term rentals, and they consistently outperform local market averages for occupancy, nightly rate, and guest satisfaction. The same strategies and systems are applied to every client property—because strong performance should be repeatable.
TRUSTED LOCAL NETWORK
As locals, we work with a trusted network of vendors, cleaners, and tradespeople who understand the urgency of short-term rentals. Jeff and Amaya have overseen multiple renovations, repairs, and construction projects, allowing issues to be handled efficiently and professionally.
A HANDS-ON PARTNER
We don’t manage from a distance, and we don’t hide behind software. Owners gain a local partner who treats their property with the same care, attention, and accountability as their own.
Local Focus. Proven Results.
MADE TO LAST
We are and always will be a company built on timeless values: trust, integrity, and a deep commitment to delivering exceptional experiences to our guests, our homeowners, our team, and every partner we collaborate with.
These values are more than just a foundation they’re our legacy.
Ultvare was created with a vision for longevity, rooted in meaningful connections and designed to grow stronger over time. Our story is one of purpose, built to stand the test of time and continue offering unmatched hospitality for years to come.
EXPERIENCE THAT SCALES.
SERVICE THAT STAYS LOCAL.
Marineland Co-Host is owned and operated by Jeff Auw, who brings 5+ years of property management and short-term rental experience and has managed over 80 short-term rentals across multiple markets.
Today, Jeff’s focus is intentionally local. That means faster response times, tighter quality control, and true hands-on oversight—without sacrificing performance.
Jeff is committed to staying ahead of a fast-changing market. He regularly attends industry conferences and educational workshops to stay current on pricing strategies, guest expectations, and the best tools and integrations available.
Details That Drive Performance
Every property receives a personalized strategy.
Jeff understands what today’s guests expect and provides clear, actionable recommendations that improve amenities, presentation, and pricing—leading to higher nightly rates and consistent five-star reviews.
Jeff’s wife, Amaya, brings design expertise that improves listing photos, increases conversion, and drives stronger booking performance through thoughtful, targeted design adjustments.
WHERE TIME BECOMES A STORY
The moments we help cultivate especially in mountain settings bring people together in simple yet deeply meaningful ways. Our mission is to ensure our clients make the highest and best use of their time by connecting them with nature in serene, intentional environments.
Ultvare is uniquely positioned to create experiences that bring purpose, peace, and connection. We've come to understand that the greatest stories are not just told they are lived. That’s why our team is dedicated to curating unforgettable experiences that become the foundation of lifelong memories and lasting bonds.
WHERE FLIXIBILITY MEETS PURPOSE
At Ultvare, flexibility sets us apart, and adaptability fuels our growth.
We’re here to help you create your sanctuary on your terms. By putting ourselves in your shoes (or boots), we take the time to understand the unique needs of every guest and property owner.
This empathy allows us to shift perspectives, recognize shared experiences, and deliver not just services but real, meaningful value and authentic connection.
LUXURY, PERSONALIZED
At Ultvare, we’ll move mountains to protect your investment, elevate your mountain time, and support each other every step of the way.
We bring a personal touch to everything we do, because we believe that exceptional partnerships are built on trust and a deeply personalized experience.
No two stories are the same and to us, luxury goes beyond where you stay. It’s about how you feel throughout your entire journey. That’s why our dedicated team works closely with you to fully customize every detail, creating a stay that doesn’t just meet expectations it redefines them.

OUR STORY
The team behind MarketMySTR has been building online businesses since 1997. Three years ago, MarketMySTR's founder Scott Hill partnered with a software developer to help grow an all-in-one marketing platform that has turned into arguably the best all-in-one marketing platform in the world.
In early 2022, Scott and Bill Faeth met each other because their daughters were on the same soccer team. During one game in Gulf Port, MS, Bill and Scott started to learn about what each other did. Unknown to either of them, until that moment, they had a common connection in Grant Cardone. Scott and his team were powering the 10X Coaching and Mentoring program for Grant, and Bill knew Grant personally! In fact, he pulled out a picture of him and Grant standing by Grant's private plane to prove it!
Scott asked more about what Bill was doing, and it turned out Bill was using a variety of software tools to manage his STR portfolio. Coincidentally, these tools were everything that Scott’s team was providing for clients and Grant’s 10X Coaching and Mentoring program, but all in one software and marketing-focused platform.
As it turned out, Bill was no novice when it came to software. Bill was customer number 33 of Hubspot and was their very first enterprise customer. In other words, he knew his stuff. Unless our all-in-one marketing platform was legit, he wasn’t going to get involved. Once we launched, Bill introduced us to Mike Sjogren and Mike Reilly. Scott was immediately impressed with their attention to detail, operationally focused mentoring, coaching knowledge, and their relentless focus on not doing everything yourself.
Ultvare, driven by the same spirit of collaboration and innovation, quickly saw the value in this all-in-one approach, bringing a seamless experience for homeowners, travelers, and property managers. Together,
these partnerships strengthened the vision for an exceptional, streamlined experience in the vacation rental industry.
