This publication is intended both for companies providing real estate services to the population and organizations, and for those who use the services of realtors. The book contains practical advice on conducting transactions with a client’s real estate, and offers the realtor a number of tips on how to check the “legal purity of an apartment.” The issues that arise for real estate firms in connection with participation in the construction of residential buildings and the registration of rights to an unfinished construction project are discussed in more detail. The book talks about the procedure for carrying out control by government agencies and explains the rights of an organization when carrying out control measures against it. In preparing this publication, the latest changes in legislation in the field of housing law, mortgages, construction investment, and accounting plan were taken into account. At the same time, the book will not only help in the work of a realtor, but will also assist a potential client of a real estate firm in order to advise how competently and qualifiedly the real estate company he has chosen works.
