He graduated from the State University of Tirana, Civil Engineering and Journalism Department. With the beginning of the privatization of properties, in 1993, together with Italian partners, he opened the first real estate agency organized in Albania, as a limited liability company. Trained in Italy in the field of real estate brokerage, he introduced the first concepts of sale-purchase or lease-rent of all types of properties. In his 30 years of work in this field, he is characterized by seriousness, honesty, correctness and professionalism. Taking a real estate valuation course with English professor David Allen, and subsequently obtaining a first-degree valuer's license in 1996, greatly deepened his knowledge of the market value of properties, linking it closely with the profession of mediator, always helping each other. The vast experience gained during the mediation of sales and purchases and the valuation of thousands of properties, led Eng. Lefter Sila to compile a study of the residential apartment market in the city of Tirana, from 1993 to the present.
