The document proposes establishing best practices and a rating system for India's affordable housing ecosystem. It discusses setting up a framework to encourage more developers, housing finance institutions and community-based organizations to enter the affordable housing space. A rating system would assess organizations on key parameters like project characteristics, loan terms, and customer facilitation. A three-step process is outlined for developing the rating system, including defining goals and objectives, evaluating key parameters and indicators, and prioritizing factors as desirable or critical. The framework aims to strengthen quality, increase transparency and help different stakeholders in affordable housing.
