Lending with Purpose
Powered by the Single-Family Mission Index
The Single-Family Mission Index provides an enduring solution for lenders to create a stronger housing market with more homeownership opportunities for qualified borrowers.
Driving Change Through Mission-Oriented Lending
The Mission Index enables lenders to identify mission-oriented lending opportunities by building on the Social Index, which Fannie Mae introduced in 2022. It reflects market feedback and includes updates to the methodology to drive positive impact for the borrowers and communities supported by our mission.
By applying numerous attributes across income, borrower, and property characteristics aligned with Fannie Mae’s mission, lenders can aim to serve a greater number of borrowers in their markets, with the potential to realize greater financial and reputational value.
The Mission Index supports originating and underwriting loans to qualified borrowers in line with our mission objectives.
Mission-oriented loan financings have the potential to reward lenders for lending to underserved borrowers and communities, helping to create social MBS in response to investor demand.
The Mission Index balances investors' desire for information with protecting the privacy of borrowers’ personal information while minimizing disruption to UMBS and the TBA markets.

Scoring Framework
The 10 criteria and overarching 3 dimensions determine
the mission-oriented scoring makeup of each pool of loans.
Understanding the Single-Family Mission Index
To show how the Mission Index functions, let's first generate the Mission Criteria Share (MCS) for a hypothetical residential MBS pool composed of 10 loans.
To begin, we'll evaluate the loans against our criteria.
Scoring Loan Pools for Mission Criteria
Each loan in a pool is scored against the mission criteria and receives a loan-level score that reflects the number of criteria satisfied.
In this example, 8 of the 10 loans meet at least one criteria.
Generating the Mission Criteria Share
This pool would have a Mission Criteria Share (MCS) of 80%, which represents the share of loans that meet any 1 of the 10 mission criteria.
Next, we’ll calculate a Mission Density Score.
Assessing Mission Density
The Mission Density Score (MDS) is generated by evaluating each loan in a pool against three dimensions: income, borrower, and property. A loan receives a score of 1 for each dimension it satisfies, for a maximum loan-level score of 3.
The average of these scores within a given pool is the MDS.*
Calculating the Mission Density Score
This pool would have a score of 2.1, representing a higher density of mission-oriented loans.
The MDS ranges from 0 to 2.5. Higher scores imply greater potential for mission impact.
