Fannie Mae Condo Reserve Requirements: Is Your Building Ready?
Fannie Mae's condo reserve minimum rises from 10% to 15% for loans from January 2027. See what changes, the reserve study route and what to budget.
What matters most
- Fannie Mae's condo reserve minimum rises from 10% to 15% of assessment income for loans from January 4, 2027.
- The loan application date, not the closing date, determines which reserve rule applies.
- A current reserve study can justify a different allocation only if the budget adopts its highest recommended funding.
- Baseline-only funding plans are reported not to qualify on Fannie Mae's reserve study route.
- Boards adopting 2027 budgets should check their reserve allocation against 15% now.
If buyers in your building use conventional mortgages, Fannie Mae's condo reserve requirements decide whether those loans can be made. For years the rule of thumb was simple: put at least 10% of the budget into reserves. That is changing. Fannie Mae's Lender Letter LL-2026-03, issued in March 2026, raises the minimum to 15% for loan applications dated on or after January 4, 2027.
For a board, that makes the 2027 budget unusually important. A budget that misses the new floor can make units harder to finance, which affects every owner who wants to sell or refinance. This guide explains the rule, the reserve study alternative, and how to check where your building stands.
I work on the software that produces reserve study funding plans, so I will focus on the part boards control: what to budget and how to prove it.
Here is what matters most:
- Fannie Mae's minimum reserve allocation rises from 10% to 15% of budgeted assessment income for loan applications dated on or after January 4, 2027, under Lender Letter LL-2026-03.
- The application date controls, not the closing date.
- A building can justify a lower allocation with a current reserve study, but coverage of the change describes conditions: the study must be recent and the budget must adopt the highest funding level the study recommends.
- Coverage of the letter also reports that the Limited Review path for established condo projects was retired in 2026, so more loans go through a fuller project review.
- The deadline is set by your fiscal year. If your 2027 budget is adopted this fall, it is the budget lenders will look at.
What the 15% rule actually measures
The test compares two numbers in your annual budget: the amount allocated to reserves, and the total assessment income. If reserves are at least 15% of assessment income, the building meets the floor. It is a budget test, not a test of your reserve balance or your physical condition.
That is also its weakness. A building can meet 15% and still be underfunded if it has a lot of aging components, and a new building can meet it easily while the money is not needed for years. The percentage protects lenders from obviously thin budgets. It does not tell you whether your roof money will be there when the roof fails. For that you need percent funded and a 30-year cash flow, which our guide on how much an HOA should have in reserves explains.
The reserve study alternative
Fannie Mae has long allowed a reserve study to justify an allocation below the percentage floor. Industry summaries of LL-2026-03 describe tighter conditions on that route:
- The study must be current. Several summaries cite a maximum age of 36 months.
- The budget must adopt the study's highest recommended funding. If the study shows several funding plans, the budget must follow the highest one the preparer recommends, not the cheapest.
- Baseline funding is not enough. Summaries report that a near-zero baseline plan, which only keeps the balance above zero, no longer qualifies on this route.
In practice, this means a reserve study can either lower your required allocation below 15% or raise it above 15%, depending on what your components need. A building with major work coming up may find the study's recommended contribution is higher than the flat percentage.
These are secondary summaries of the lender letter. Your lender and Fannie Mae's Selling Guide are the final word, so ask your management company or lender to confirm how they will apply it to your building.
What else is changing in condo reviews
Coverage of the 2026 changes also reports that Fannie Mae retired the Limited Review path for established condo projects in August 2026, and that some smaller projects, such as two-to-four-unit condos and detached condo units, remain exempt from project review. If your building used to qualify for a lighter review, expect lenders to ask for more documents: the budget, the reserve study, insurance details and questionnaires about repairs and litigation.
Fannie Mae also continues to scrutinize buildings with significant deferred maintenance or unsafe conditions. Buildings with critical repairs outstanding can be ineligible until the work is done or funded. That is another reason boards should keep their reserve study and any structural reports current.
How to check your building before the 2027 budget
- Calculate your reserve allocation as a share of assessment income in the draft 2027 budget. If it is under 15%, decide now whether to raise it or rely on a reserve study.
- Check the date of your reserve study. If it is more than three years old, plan an update before you rely on it to justify a lower allocation.
- Read the study's funding plans. Identify the highest recommended contribution and compare it with your budget.
- Run the 30-year cash flow. Even if you meet 15%, check that the fund does not run short in a future year. Our free HOA reserve fund calculator shows that year and the contribution that avoids it.
- Talk to your management company and lender so the condo questionnaire you return reflects the new rule.
What happens if a building does not meet the requirement
Units in a building that does not meet Fannie Mae's project standards can be harder to finance with conventional loans that Fannie Mae buys. Buyers may need other loan types, larger down payments or cash. That tends to narrow the buyer pool and can affect prices. For owners, it is one of the most direct ways a board's budget decisions show up in their property values.
Frequently asked questions
What are Fannie Mae's condo reserve requirements?
Fannie Mae requires condo projects to allocate a minimum share of budgeted assessment income to reserves. The minimum has been 10%, and Lender Letter LL-2026-03 raises it to 15% for loan applications dated on or after January 4, 2027. A current reserve study can justify a different amount under conditions.
Can a reserve study replace the 15% requirement?
According to summaries of the lender letter, yes, if the study is current and the budget adopts the highest funding level the study recommends. A baseline-only plan is reported not to qualify. Depending on the building, the study's recommendation may be lower or higher than 15%.
When does the 15% condo reserve rule take effect?
For loan applications dated on or after January 4, 2027. The application date controls, so a loan application dated before then is reviewed under the older 10% standard.
Does the 15% rule apply to every condo?
No. Coverage of the change reports that Fannie Mae waives project review for some small projects, such as two-to-four-unit condos and detached condo units. Larger established projects going through a full review are the main focus. Your lender can confirm which review applies.
For reserve study firms
The 15% rule means more boards need a current study, fast, before budget season. If your reporting backlog is the constraint, our engine drafts the full study from inspector notes and photos in your template, with every funding plan calculated for your professional to review.
