Aiya facilitates over $140 million dollars in real estate property transactions — both personally and as part of development firms such as Zachekndorf Development with a total portfolio of $4 billion dollars.

Aiya also works with Costas Kondylis & Associates, AvalonBay, The Shemesh Team, Extell Marketing Group LLC, Kolter Healthy Home, Toll Brothers, and many others, prosperously navigating the US real estate market for her clients. She provides clear, actionable advice thanks to her nuanced understanding of market volatility. Her profound knowledge and experience allow her to successfully help her clients expand their real estate holdings.

Valuation of real estate and selection of long term, profitable properties requires years of experience and connections. Clients often want to establish a concrete real estate portfolio in the United States in hopes of leading lasting gains.

However, without a clear understanding of real estate trends, it is easy to fall short and miss out on key benefits. Analyzing my clients’ preferences and their vision of their property investment, I devise a clear plan to help them achieve these aspirations and avoid mistakes and losses. I advise and provide clear steps, assets, and if needed, additional experts that can make their dreams a reality. Steadily, it is then possible to amass holdings that fit the requirements established during the VIP consultations.
