Hi, there! Here in Russia there is such thing like share construction or participatory constructon. It's when ordinary people pre-pay money for the flats that don't even physically exist at the moment, at the stage of projecting. A building company announces such a project on TV and Internet, people come to the offices of the company, choose a flat according to the project, study documentation and sign contracts. They pay money and in a few years they get their apartments built and that's it.
There are a few regulatory constraints and laws issued by the government, which controls this real estate sector so theoretically it's safe.
Is there anything like this in your country? How is it properly called? Do companies try to cheat?
