ROSI™ Real Estate is a research-based framework designed to quantify the financial value generated by sustainable business practices in the affordable housing sector. It utilises the Return on Sustainability Investment (ROSI™) methodology to demonstrate how social and environmental initiatives, such as resident stability programmes, translate into tangible financial performance. This tool is particularly relevant to finance professionals and real estate investors looking to bridge the gap between social impact and net operating income (NOI).

Organisation behind the tool

The framework was developed by the NYU Stern Center for Sustainable Business. The research includes case studies and practical applications in collaboration with organisations such as Mercy Housing.

What the tool does

The tool provides a structured approach to identifying and valuing the financial benefits of sustainability-related investments in real estate. Key functions include:

• Analysing how Housing Support Plans for residents in default can reduce turnover costs and legal fees.
• Quantifying the impact of resident stability on long-term cash flow and property valuations.
• Providing a methodology to link ESG (Environmental, Social, and Governance) metrics to traditional financial statements.
• Offering case studies that demonstrate how social interventions improve Net Operating Income (NOI).

Target audience

The primary audience includes affordable housing providers, real estate asset managers, and institutional investors. It is also a resource for ESG analysts, researchers, and policymakers focused on sustainable urban development.

Relevance to finance professionals

This tool applies to finance professionals in the following ways:

• Risk assessment – Identifying and mitigating financial risks associated with resident turnover, vacancy rates, and eviction processes.
• ESG analysis – Providing a robust framework to report on the “Social” component of ESG by linking it to direct financial returns.
• Investment context – Demonstrating how social impact initiatives in real estate can lead to improved financial stability and higher long-term yields.
• Market insights – Understanding how operational efficiency in affordable housing is enhanced through resident engagement and sustainability strategies.
