AHIC ADOPTS UPDATED RISK RATING GUIDELINES FOR LOW-INCOME HOUSING TAX CREDIT PROPERTIES

LEESBURG, VA -- The Affordable Housing Investors Council (AHIC) has adopted updated Risk Rating Instructions and Guidelines for evaluating the performance and risk profile of Low-Income Housing Tax Credit (LIHTC) investments.

The revisions modernize AHIC’s long-standing framework by shifting from a primarily checklist-based approach toward a risk-based framework that explicitly recognizes credible mitigants and the role of professional judgment in evaluating investment performance. The updates are intended to promote more accurate, consistent, and defensible risk ratings across LIHTC investor portfolios.

The revised guidance strengthens the consistency and governance of risk ratings by requiring any decision to maintain or improve a rating to be supported by documented and quantified mitigants, rather than relying solely on threshold-based metrics.

Key updates include:

Mitigant-driven rating logic, allowing investors to consider factors such as guarantor support, reserves, contractual extensions, and operational trends when evaluating risk.
Phase-specific guidance covering the construction, lease-up, and stabilized operating phases of LIHTC investments.
Enhanced watch list governance, including clearer expectations for monitoring assets rated C or and an expectation that assets should not remain at a C rating for more than 12 months without documented mitigants supporting the rating.
Institutionalizing Downside Analysis (DSA) for stabilized properties performing below break-even or experiencing sustained underperformance.

The updated framework also introduces several structural refinements, including:

Separating construction and lease-up risks in the development-phase grid;
Incorporating Expense Coverage Ratio (ECR) alongside Debt Coverage Ratio (DCR) for stabilized assets; and
Updating terminology to emphasize the role of GP/Guarantor/Management (GGM) in supporting property performance.

The revised Risk Rating Instructions and Guidelines (available here) are being published now for an interim period to allo
w for industry review, questions, and implementation. AHIC is encouraging industry adoption by the fourth quarter of 2026.

An Executive Summary of the changes is available on AHIC’s website, including practical guidance for industry application of the updated framework.
AHIC will also maintain an FAQ document that will be maintained and updated as needed to reflect any received feedback or implementation questions.
To support implementation, AHIC will host a webinar on June 18, 2026, where members of the Asset Management Committee will review the changes and address questions from investors and industry participants.

The revisions were developed over the past year by AHIC’s Asset Management Committee, with input from member institutions and feedback from industry partners.
