Долевое строительство is when people who want to buy an apartment invest in the construction of the building they want that apartment in. This way they don't buy a specific apartment but just have there "share" in the overall construction cost. This is where долевое comes from. Ты в доле

Unfortunately this is where those people often get ripped off. As they don't buy an apartment there can be hundreds of excuses to not build the building afterwards.
