Adriana Montbrun Key Biscayne and Miami Realtor

By Adriana Montbrun

If you are reading this, you are probably looking for an agent to help you with a real estate transaction in Key Biscayne; you probably know Key Biscayne is Miami’s best kept secret, a private island just ten minutes off Brickell connected to the mainland via a panoramic causeway with ocean on both sides, where residents enjoy a laid back affluent lifestyle.

With slightly over 1,200 homes and 5,500 condos, Key Biscayne is home to CEO’s, investors, conglomerate owners and many families who appreciate the privacy, convenience and sense of community the island provide in slightly more than a square mile. Many great restaurants, two state parks, award winning golf and tennis, endless beaches, a Ritz Carlton, several schools, churches, golf cart usage throughout the island are just a few of the benefits afforded by an island lifestyle that unlike Fisher Island, does not require a ferry or private boat to gain access. 

After a record breaking 2021 across the entire South Florida, Miami and Key Biscayne real estate market, the key question is how to move forward. 

That is also why, more than ever professional help from a top Key Biscayne realtor is more important than ever.  It is likely you seek some of the following:

Most people know a realtor, with buyers or sellers often hiring a person that is close to them, in some cases feeling obliged to hire that family member or friend. This used to work fine when the role of a Miami luxury real estate agent was just to make a few calls, show properties and contact third parties for inspections, financing, etc. A top realtor in Key Biscayne will make all the difference in your bank account as well as your mental health!

“Real estate has changed dramatically over the last 5 years. Technology and data surrounds us (i.e. virual tours, listing databases, facetime showings, eMarketing, etc) and a good agent has to master all these new technologies, be good at monetizing information and embed the human element and local knowledge on each transaction.”

A Top Realtor in Key Biscayne will have Local Market Knowledge that can translate into delivers financial returns

As a buyer you would likely want to hire an agent who knows the market and the numbers, who can provide context and “on-the ground” perspective to the flood of data available through search engines; someone who understands where we are in the Miami  real estate economic cycle, its previous bottom and peak prices so you can formulate your entry and exit price points. In other words: you need “trusted feet on the ground” , someone that understands your lifestyle needs and a real estate market analyst with access to data that will help make financial decisions. 

Key Biscayne Realtor Knowledge

Key Biscayne is a relatively small community that people not familiar with the island may have a difficult time understanding and explaining. For us locals, it is paradise; a place to enjoy a laid back lifestyle, a safe home surrounded by a cosmopolitan affluent community with exciting and varied life stories. Captains of Industry, Fortune 500 CEO’s, business owners and even presidents (i.e. Nixon) call Key Biscayne home. A place surrounded by two large parks (i.e. State and county), some of the best ranked beaches in America, a gorgeous golf course, many restaurants, a 5 star Ritz Carlton property, top schools, etc. 

The Key offers many options only experienced local realtors can help you navigate. Maybe you’d like to dock a large boat along Hurricane Harbor, maybe enjoy a Miami skyline view along Harbor drive; you might seek a fully redone unit in an oversized lot, or walking to the beach from your home in Holiday Colony. If you’d rather live in a Key Biscayne condo, you may want to explore modern premium units at Oceana, flow through plans at Ocean Club, corner corner units in Grand Bay, Ocean Club or Mar Azul or the wide options at Key Colony, Commodore Club and Towers of Key Biscayne.

Whatever your needs, I am here to help you find the Key Biscayne property that fits your lifestyle and financial expectations.

If knowledge is power then DSG could be considered the most powerful team of agents in Miami real estate, at least by analytical standards. We have been writing articles and supremely detailed ‘actionable’ reports (Including the more recent Key Biscayne Condo Market Update Q1 2021 and the Key Biscayne 2020 Condo Market Update & 2021 Market perspectives) for over a decade now. I say actionable because our reports do not just give a bunch of arbitrary statistics, but actual actionable advice for buyers and sellers specific to their price point). Advice that delivers value to our clients such as the following transactions:

A Top Realtor in Key Biscayne combines Local Knowledge, Data Access, Global Client networks and strong Interpersonal skills

A buyer would want to hire the agent who knows the market, its numbers and makes sure you do not overpay for a property. Someone who will be able to understand what the numbers mean, where the trends point to and have the interpersonal skills to help navigate the emotional aspects of a purchase including negotiations as well as the key transaction points when deals fall through or can become more onerous.

Choose from All Miami Real Estate Homes, not just what is on the Market

Why limit yourself to listed Miami Real Estate homes if we can offer you so much more. Many of our clients bought a house that wasn’t even on the market. As a team we will go out of our way to find your dream house even if it means approaching owners of off-market properties. We have a large database of Miami Real Estate home owners and we often reach out to specific off-market properties upon request of potential buyers. Moreover as top producing Miami realtors we are constantly in contact with other agents communicating which new product is coming up and as a result we know about new properties before anyone else does. My group sold over $72M in off-market Miami real estate transactions in 2021.

What to look for in a Key Biscayne Realtor when Selling?

A Top Realtor in Key Biscayne is One with the Best Online Presence and Local Exposure

Selling Key Biscayne and Miami real estate in 2022 requires a strong, modern marketing mind. Someone who has a broad outreach, who talks to agents and buyers around the globe and does not limit him or herself to local Key Biscayne residents and acquaintances.You need a Key Biscayne real estate agent who does not rely on the MLS to have your property sold, but takes it the extra mile with videos, flyers and a large database of buyers.

Miami Real Estate Digital Marketing

Key Biscayne is part of the Miami metropolitan area, a global city where buyers, particularly in 2022, often come from out of town, so you don’t want to limit yourself to an agent whose reach is only hyper local; domestic US relocation has been a big market driver in 2021 and  foreign buyers continue to be very big players in Miami Real Estate, something that will only increases as the pandemic relents, borders open up and people resume free movement. This is why we created the relocation campaigns, the annual reports and weekly blogs based on what people are searching for. 

 98% Of searches start online, so having the top website in South Florida – as ranked by our peers in South Florida agent magazine in December 2021 – makes sure you have a leading edge.  A top Key Biscayne realtor also should have  national and global reach for its listings and that is what we have to offer as we leverage the top resources not just from our group but also from Douglas Elliman, the leader in residential luxury real estate and Knight Frank, globally.

Our website Luxlifemiamiblog has been rated the best website for 2022 in Miami and South Florida, drawing tens of thousands of visitors

Our fundamental goal is to expose your property to the right audience with the right message. It is about targeting a specific audience such as investors, tax refugees or relocating families with geo-specific campaigns and the right message. As you might know these days most buyers are relocation buyers coming for the high tax states (mostly the northeast) who are looking for good quality homes near Miami’s best private schools in Miami’s safest areas. We know how to target these relocation buyers and how to keep them interested as we offer very specific and targeted videos and blogs. 

Feel free to google important search terms like “Relocating to Miami” or “Key Biscayne homes for sale” and you will see our website ranks numbers one. We are also number one for important terms like: “The Best Miami Private schools”, “The best gated communities in Miami/Key Biscayne” or “The safest areas in Miami”, which is something that most relocation buyers search for before they start looking for specific real estate options. This is how the majority finds us!

These potential buyers have to subscribe to our site and they will receive a personal phone call as well as our e-mail blasts. As we get many new subscribers to the website I have a very large database of buyers who are actively looking for high quality homes in a very competitive market. One of the reasons I sell my properties very fast is because I pre-market them to my database and a short list of buyers I have in mind for every new listing I take on.

Traditional Marketing and Social Media

When we take on a listing we write a targeted blog and create a professional video. We will send professionally designed email flyers to local agents, buyers as well as top producing agents around the country in cities like NY, LA and Chicago. We also often personally call Miami’s top agents to inform them about the new listing.

Targeted blogs can be a blog about your property, but also a blog on the desirability of your type of property. In case your home is located in a gated community we will write an article on your gated community, which then features your home. When you are selling a golf course home we will write an article on Golf Course homes featuring your listings and so on. These blogs will then be published on our social media, shared with our buyers and often we will have digital campaigns to reach the right audience (buyers).

Exclusive listing videos and 3D Tours

We hire a professional photographer and videographer to shoot your property. Please find below two exclusive listing videos we have used for our marketing, which in times of Covid are complemented by a professional 3D Virtual Tour.

Social Media

Both me and The David Siddons Group personally post on several social media on a daily basis. We are also able to leverage the social media channels of Douglas Elliman and several other large real estate accounts. We have access to the Instagram accounts (depending availability) of @theDavidsiddonsgroup (37K and growing fast), @DouglasElliman (215K followers), @DouglasEllimanFlorida (52K followers), @luxury_homes (1,3M followers) and @bossestate (210K followers).
