Ștefan Ionuț Costin, Founder of Ilfov Imobiliar – Entrepreneurship, real estate and building a trusted brand in the Northern Ilfov area

Ștefan Ionuț Costin, founder of Ilfov Imobiliar, discusses entrepreneurship, Northern Ilfov real estate, property marketing, transparency, and building a trusted results-driven brand.

Ștefan Ionuț Costin is an entrepreneur and real estate broker, as well as the founder of Ilfov Imobiliar, an agency specialized in the Northern Ilfov area, where he has built one of the most visible and respected local brands, supported by hundreds of completed transactions and more than 300 five-star client reviews. His work is complemented by a strong online presence, with a community of over 50,000 followers, built through educational content and transparent communication.

C&B: If we were to look at the narrative thread of your career, what were the key moments that defined you?

Stefan Costin: My career was not defined by a single moment, but by several stages that shaped me. One of the most important was the moment I decided to move away from the traditional real estate approach and build a business based on exclusive representation and complete transparency.

Another defining moment was the decision to focus on Northern Ilfov, an area with high potential that was not being professionally leveraged at the time. In addition, developing a consistent online marketing strategy contributed significantly to differentiating us in the market and increasing our visibility.

C&B: What has been the most difficult moment in your journey so far, and how did you overcome it?

Stefan Costin: The most difficult challenge was earning people’s trust in an industry where skepticism is, understandably, common. Many property owners start with the idea that they can manage the process on their own or have unrealistic expectations regarding price.

I overcame this obstacle through consistency, results, and most importantly, honest communication. I never tried to tell clients what they wanted to hear, but rather what they needed to know. Over time, this was reflected in referrals and positive client feedback.

C&B: Is there a dream or ambition that has always guided you, regardless of obstacles?

Stefan Costin: My ambition has been to change the perception of the real estate agent. I want agents to be seen not as simple intermediaries, but as true partners in the selling or purchasing process. I aim to build an agency recognized for professionalism, results, and ethics, while also contributing to raising standards within the industry.

C&B: How did you build client trust in a field where transparency is essential?

Stefan Costin: Trust is not something you ask for, it is something you build. I achieved this through accurate evaluations, clear communication, and taking responsibility for every transaction.

We do not promise unrealistic results and we do not distort reality just to secure a contract. Over time, the results became the strongest validation: more than 300 five-star reviews and a community of over 50,000 online followers that reflects clients’ trust in our services.

C&B: If we were to meet your team or collaborators, what do you think they would say about you?

Stefan Costin: I believe they would say that I am demanding, but fair. I focus on results, but also on the growth of every team member.

I enjoy working with people who want to grow and who understand that performance comes from discipline, involvement, and responsibility.

C&B: Why did you choose to focus exclusively on the Northern Ilfov area, and how has this niche positioning influenced the development of your business?

Stefan Costin: I chose Northern Ilfov because I saw opportunity where there was not enough professional attention. It is an area in continuous development, with real investment potential.

Specialization allowed us to deeply understand the market and provide real consultancy, not general advice. Over time, this approach helped us become one of the most visible and relevant real estate brands in the northern area of Bucharest.

C&B: You have reached hundreds of transactions and a high success rate. What do you consider to be your company’s main differentiator?

Stefan Costin: The main differentiator is the way we treat every property, as a product that needs to be properly positioned in the market.

We do not limit ourselves to listing properties; we invest in strategy, marketing, and presentation. We work mainly through exclusive representation, which allows us to control the process and deliver concrete results for our clients.

C&B: What does a typical day look like for you now, and which moments bring you the greatest satisfaction?

Stefan Costin: There is no typical day in real estate. The work is dynamic and involves constant interaction with people, market analysis, property viewings, and negotiations.

The most satisfying moments are when a transaction is successfully completed under good conditions for all parties involved. That is when you truly see the tangible result of your work.

C&B: What values or principles guide you in what you do, and how do you apply them daily?

Stefan Costin: Transparency, professionalism, and responsibility are the core values behind my work.

I apply them every day through the way I communicate with clients, the decisions I make, and the way I handle each transaction. In a field where trust is essential, these values are not optional.

C&B: How was Ilfov Imobiliar created, and what opportunity did you identify in the market at the time of its founding?

Stefan Costin: Ilfov Imobiliar was born from the desire to do things differently. I noticed the lack of professionalism and strategy in the market and believed there was room for an agency focused on real consultancy and marketing.

We started with small steps, but with a clear vision and the goal of building a relevant brand in the area where we operate.

C&B: Are you considering expansion into other areas, or will you remain loyal to the concept of local specialization?

Stefan Costin: In the long term, expansion is a natural direction, but not at the expense of quality.

I believe in specialization and in strengthening our position in the area where we operate. I would rather be very good in one clear segment than mediocre in several.

The story of Ștefan Ionuț Costin reflects the evolution of an entrepreneur who successfully transformed transparency and strategic marketing into a real competitive advantage in the real estate market. Through the development of Ilfov Imobiliar and a strong focus on the Northern Ilfov area, he demonstrates how professionalism, consistency, and trust can build a powerful and relevant brand in the Romanian real estate industry.
