On March 18, 2026, Fannie Mae issued Lender Letter LL-2026-03, and Freddie Mac released Guide Bulletin 2026-C. Together, these documents introduce the most substantial updates to condominium and cooperative lending standards in several years. The changes roll out across multiple dates through early 2027, and buyers may lose access to conventional conforming financing through Fannie Mae and Freddie Mac, although alternative financing may still be available, often at higher cost.

This article explains what changed, when each requirement takes effect, and what boards and property managers should understand to keep their buildings eligible.

Why These Standards Matter

Fannie Mae and Freddie Mac are government-sponsored enterprises that purchase mortgages from lenders after origination. Because lenders know these agencies will only acquire loans meeting specific eligibility criteria, those criteria effectively govern most conventional residential mortgages across the country.

The critical point for condominium and cooperative communities: Fannie Mae and Freddie Mac evaluate the entire project, not only the individual borrower. When a building's finances, reserves, or insurance fall outside their standards, buyers in that building cannot obtain affordable financing. Sellers struggle to find qualified purchasers. Property values across the entire community reflect the reduced demand.

A loan on a property that meets these standards is called “warrantable.” One that falls outside them is “non-warrantable.” Non-warrantable loans typically require larger down payments, carry higher interest rates, and impose stricter qualification requirements. The distinction affects every owner in the building, regardless of their individual financial standing.

The Origin of These Changes

In June 2021, the Champlain Towers South condominium in Surfside, Florida partially collapsed, resulting in 98 deaths. Investigations revealed long-standing structural deterioration, documented deferred maintenance, and chronically underfunded reserves. Fannie Mae and Freddie Mac began implementing enhanced condominium underwriting standards in response, starting in late 2021. The March 2026 updates (Fannie Mae and Freddie Mac) represent the latest chapter in that ongoing effort.

The Community Associations Institute (CAI), the leading national organization for community association professionals, has tracked the real-world impact through ongoing research. In a survey of over 700 board members, property managers, and business partners, CAI's Foundation for Community Association Research found that 42% of respondents were unsure whether their community qualified for federally-backed financing. Among those already deemed ineligible, 64% reported that the determination had negatively impacted home sales or property values in their building.

What Changed: The Three Key Dates

The 2026 updates take effect across three distinct dates. Each introduces requirements that boards and property managers should understand.

July 1, 2026: Insurance Deductible Requirements

Effective for loan applications dated on or after July 1, 2026, master property insurance policies for condominium and cooperative projects must comply with a new per-unit deductible standard. The maximum allowable per-unit deductible is now $50,000, replacing the previous formula that permitted 5% per-unit deductible calculation.

This change applies to both condominiums and cooperatives. Buildings with master policies carrying per-unit deductibles exceeding $50,000 will fall outside eligibility requirements until the policy is adjusted.

Additionally, when the master policy includes a per-unit deductible, unit owners should maintain an HO-6 policy with sufficient interior coverage to help satisfy the association's deductible obligations and protect their unit improvements and personal property.

August 3, 2026: Full Review Becomes Mandatory

Effective for loan applications dated on or after August 3, 2026, the Limited Review process has been eliminated for established condominium projects with more than 10 units. Every loan in those communities must now proceed through Full Review.

The distinction matters significantly. Limited Review was a streamlined pathway that allowed lenders to approve loans primarily by evaluating the borrower's qualifications, with minimal examination of the building itself. Full Review requires a comprehensive evaluation of the association's budget, reserve funding, insurance coverage, delinquency rates, pending litigation, special assessments, and inspection reports.

For cooperative projects, this change has a different implication: cooperatives have always required Full Review. The Limited Review pathway was never available for co-op financing. The August 3, 2026 change primarily affects condominiums, bringing them to the same standard that cooperatives have long followed.

The project review waiver has been expanded to cover communities with 10 or fewer units, up from the previous threshold of four units. For projects in the five-to-ten-unit range, the community cannot be part of a master association or larger development. The majority of condominium and cooperative communities exceed this threshold, meaning Full Review will apply to most buildings.

January 4, 2027: Reserve Funding Increase

Effective for loan applications dated on or after January 4, 2027, the minimum reserve funding requirement increases from 10% to 15% of total annual budgeted assessment income. For a community collecting $500,000 annually in assessments, this represents an additional $25,000 per year that must be allocated to reserves rather than operating expenses. Buildings currently funding below this threshold will need to adjust their budgets accordingly.

The 15% minimum can be satisfied through an alternative pathway: if the association has a reserve study completed or updated within the last three years and is funding reserves at the highest recommended level identified in that study, the percentage formula does not apply. However, the baseline funding method, which essentially targets a near-zero reserve balance, is no longer permitted under any circumstances.

Other Notable Changes

In addition to the changes taking effect on July 1, August 3, 2026, and January 4, 2027, Fannie Mae and Freddie Mac also made several revisions intended to simplify and modernize project eligibility standards. Among the more notable updates:

• Owner-occupancy requirements have been eliminated for established condominium projects, meaning lenders are no longer required to verify a minimum percentage of owner-occupied units as part of project eligibility.

• Investor concentration limits have been removed, eliminating previous restrictions based on the percentage of units owned by a single investor or entity.

• Property insurance requirements have been updated, including revisions to replacement cost valuation standards, inflation guard provisions, deductible buy-back coverage, and other insurance eligibility criteria.

While these changes generally reduce administrative burdens in certain areas, they do not lessen the agencies' increased focus on adequate reserves, insurance coverage, and the long-term structural and financial health of condominium and cooperative communities.

Condominium and Cooperative Differences

The regulatory framework treats condominiums and cooperatives differently in several respects. Understanding these distinctions helps boards and property managers identify which requirements apply to their specific building type.

Full Review Requirements

Condominiums with more than 10 units will require Full Review effective August 3, 2026. Cooperatives have always required Full Review; the August 3 change does not alter their status.

Insurance Requirements

Both condominiums and cooperatives must maintain master property insurance covering all insurable property elements and are subject to the $50,000 per-unit deductible cap effective July 1, 2026. While certain insurance requirements differ between condominium and cooperative projects under Fannie Mae and Freddie Mac guidelines, boards should review their coverage with their insurance professional to confirm compliance with the applicable agency standards.

Reserve Requirements

Both condominiums and cooperatives are subject to the reserve funding minimum, which increases to 15% effective January 4, 2027.

What Full Review Examines

When a lender conducts a Full Review, it evaluates the association's financial, insurance, legal, and operational documentation. Depending on the project and any known structural concerns, lenders may also request engineering or inspection reports. Property managers and boards should anticipate inquiries across the following areas:

• Financial Documentation: Annual budget, most recent audited financial statements, reserve fund balance and funding plan.

• Insurance Verification: Master property insurance certificates, verification of per-unit deductible amounts, confirmation of required coverage types.

• Delinquency Data: Percentage of unit owners more than 60 days past due on assessments. Fannie Mae requires that no more than 15% of owners be delinquent.

• Legal and Structural Status: Disclosure of pending litigation, special assessments, known structural or safety issues, and, where applicable, engineering reports, inspection reports, or other documentation related to the building's condition.

• Reserve Studies: If the association relies on a reserve study to satisfy the funding requirement, the study must be current within three years, and the association must be funding at the highest recommended level.

Buildings that are disorganized or slow to produce documentation are already experiencing delayed closings. Industry reports indicate that transactions in unprepared buildings are stretching from a typical 30-day closing to 45 or 60 days, simply because lenders are waiting on paperwork.

The New York Consideration

Much of the current media coverage focuses on Florida condominiums, where the intersection of aging building stock, rising insurance costs, and new state inspection requirements has created acute pressure. The August 3 changes will intensify that pressure.

For New York cooperatives, the situation is different. Cooperatives have always operated under Full Review requirements. The August 3 elimination of Limited Review does not change their status. However, the July 1 insurance requirements and the January 2027 reserve requirements apply equally to cooperatives. New York cooperative boards should focus on the insurance deductible cap and the upcoming reserve threshold. These are the areas where compliance gaps are most likely to emerge.

What Proactive Boards Should Consider

Several actions can help buildings maintain eligibility and avoid transaction delays:

• Review current reserve funding levels. If the association is funding below 15% of annual assessment income and does not have a qualifying reserve study, budget adjustments will be necessary before January 2027.

• Commission or update a reserve study. A current reserve study, completed or updated within three years, provides the most flexibility in meeting the new funding requirements. The study must use a methodology that maintains adequate balances over time; baseline funding approaches that target near-zero balances are no longer acceptable.

• Verify insurance compliance. Confirm that the master insurance policy carries a per-unit deductible at or below $50,000. If the current policy exceeds this threshold, adjustments must be made during your next renewal cycle.

• Organize documentation. Full Review requires prompt production of budgets, financial statements, insurance certificates, delinquency data, and legal disclosures. Buildings with organized records experience faster closings and fewer complications.

The Broader Implication

The 2026 changes reflect a continuing shift in how condominium and cooperative financing is evaluated. The emphasis has moved from individual borrower qualifications toward comprehensive assessment of the building itself. A well-qualified buyer cannot compensate for a building that falls outside eligibility standards.

For boards and property managers, this means that building-level financial health directly affects every owner's ability to sell, refinance, or transfer their unit. The buildings that prepare now, by ensuring adequate reserves, compliant insurance, and organized documentation, will maintain access to conventional financing. Those that delay may find their owners facing a constrained market and reduced property values.

The information already exists. The opportunity is to organize it, verify compliance, and be ready when lenders ask.
