At that time multi-apartment houses began to build quickly, the rooms of these houses were rented. This method of investment was the most advantageous in terms of obtaining a passive income. Later people learned how to get more profit from such apartment blocks. So, on the ground floors lived the intelligentsia, the upper floors were occupied by various workers and craftsmen, and on the attics bestowed upon the poor. Thus, housing was available for rent to all classes of the society, that allowed to get significant income.
The rent of the property is one of the strategies used by our project!
