Reserve fund requirements are one of the most consequential — and most frequently misunderstood — areas of HOA and condominium association governance. The rules come from multiple directions: federal mortgage guidelines, industry standards, and your association’s own governing documents. Getting this wrong doesn’t just create financial risk. It can affect whether buyers in your community can obtain financing and whether sellers can sell.
Here is a clear breakdown of what associations need to know.
Federal mortgage requirements: Fannie Mae and Freddie Mac
Fannie Mae and Freddie Mac back approximately 70% of the conventional mortgage market in the United States. That means their eligibility rules directly govern whether lenders can offer standard financing to buyers and refinancing owners in your community. If your association falls out of compliance with their guidelines, the impact is felt immediately by individual unit owners — not just the board.
Following the collapse of the Champlain Towers South condominium in Surfside, Florida in June 2021 — which claimed 98 lives — both agencies substantially tightened their reserve and structural requirements for condominium and cooperative communities. The updated guidelines took formal effect on September 18, 2023, and apply to all condominium and cooperative projects with more than five attached units.
The 10% reserve rule — and the 2027 increase
Under current guidelines, Fannie Mae and Freddie Mac require that condominium associations allocate a minimum of 10% of their total annual budgeted assessment income to their reserve fund. Starting January 4, 2027, that threshold increases to 15% for communities reviewed under Fannie Mae’s standard Full Review process. Failing to meet the applicable threshold can make a project ineligible for conventional financing.
The reserve study alternative
Critically, communities with a current, properly funded reserve study can meet an alternative standard and avoid the percentage-based threshold entirely. Fannie Mae waives the 10% — and the forthcoming 15% — requirement if the association has a reserve study in place that is current and being followed. This is one of the most important reasons to maintain an up-to-date reserve study: it is not just good financial planning, it is a direct tool for protecting your community’s mortgage eligibility.
Delinquency limits
Both agencies also set firm limits on assessment delinquency. A project becomes ineligible if more than 15% of total units are 60 or more days past due on their HOA assessments or special assessments. This means that a board’s commitment to consistent, professionally managed collections is directly connected to the community’s ability to attract buyers with conventional financing.
Additional eligibility requirements
Under the 2023 guidelines, communities with critical repair needs, active evacuation orders, or unfunded repairs exceeding $10,000 per unit are also considered ineligible. Associations must be prepared to provide lenders with current documentation on reserve funding, structural condition, and pending repairs when requested. Failure to provide this information can result in the community being placed on Fannie Mae’s ineligible project list — a designation with serious consequences for property values and owner exit options.
Industry standards: Community Associations Institute
The Community Associations Institute (CAI) is the leading national authority on community association governance and management. CAI’s National Reserve Study Standards, most recently revised in 2022, establish best practices for reserve study frequency, methodology, and funding that are widely referenced by lenders, courts, and state regulators.
CAI recommends that associations conduct a full, site-visit reserve study at minimum every three years, with annual updates in the intervening years to account for inflation, project completion, and changing conditions. For older or more complex properties — such as high-rise coastal buildings with significant shared infrastructure — more frequent full studies are advisable given the accelerated wear these properties experience.
Practical frequency guidelines
Drawing from CAI standards and industry best practices, the recommended schedule for most associations is:
- Full reserve study with on-site inspection: every three to five years
- Annual updates: every year between full studies to adjust for completed projects, inflation, and reserve balance changes
- Older or high-complexity properties: full study every two to three years given faster component deterioration
Reserve studies must be conducted by a credentialed professional. The two primary credentials are the Reserve Specialist (RS) designation from CAI and the Professional Reserve Analyst (PRA) designation from the Association of Professional Reserve Analysts (APRA).
The lending impact on your community
For coastal resort and condominium communities in particular, the connection between reserve fund compliance and property values is direct and significant. When a community’s reserves are inadequate, undocumented, or out of compliance with lender guidelines:
- Buyers using conventional financing may be unable to purchase in the community
- The pool of eligible buyers shrinks, reducing competition and suppressing sale prices
- Existing owners attempting to refinance may be blocked
- The community risks being placed on Fannie Mae’s ineligible project list, compounding all of the above
A properly maintained, currently funded reserve study is one of the most effective tools a board has to protect unit owner property values and ensure the community remains accessible to the broadest possible buyer pool.
How Tradd stays current on changing requirements
Reserve fund requirements — particularly those tied to federal lending guidelines — are not static. The Fannie Mae and Freddie Mac guidelines have changed significantly since 2021 and will continue to evolve. In March 2026, both agencies issued additional updates affecting insurance requirements, reserve funding requirements, and other eligibility standards, with further changes continuing to be reviewed by the industry.
Tradd monitors these developments through active membership and engagement with the Community Associations Institute, ongoing review of Fannie Mae and Freddie Mac lender bulletins, relationships with real estate attorneys and lenders active in the Grand Strand market, and our in-house accounting team who track compliance requirements that intersect with association financial management.
When requirements change, we assess the impact on every community we manage and communicate proactively with boards before they are caught off guard. Staying current on these requirements is not optional for a well-run association — and it is not optional for Tradd.
Reserve fund compliance is one of the areas where the quality of your management company has the most direct financial impact on every unit owner in your community. If your board is uncertain whether your reserve funding meets current Fannie Mae and Freddie Mac standards, we’d welcome a conversation.
