Fannie Mae Condo Reserve Requirements: 10% to 15% in 2027

Fannie Mae condo reserve requirements come down to one line on your budget: to stay eligible for conventional mortgages — "warrantable," in lender language — a condominium's annual budget must allocate at least 10 percent of budgeted assessment income to replacement reserves. For loan applications dated on or after January 4, 2027, that minimum rises to 15 percent, and Freddie Mac matches the change on the same date. There is one exception — a reserve study less than three years old whose highest recommended funding level your budget actually follows — and one deadline that lands even sooner: on August 3, 2026, Fannie Mae retires the Limited Review process that let a large share of condo loans close without anyone reading the association's budget.

That's the rule in one paragraph. What follows is what a board does about it: where the number comes from on the budget you already have, how to compute yours tonight, how the reserve-study escape hatch works, and how to close a five-point gap without an owner revolt. If your reserve contribution sits between 10 and 15 percent of assessment income, you have roughly one budget cycle to act.

Why a Mortgage Rule Is Your Board's Problem

Fannie Mae and Freddie Mac don't make loans — they buy them from lenders, and together they stand behind roughly half of the U.S. mortgage market. When your project meets their standards, any lender can write a standard conventional loan on any unit in the building. When it doesn't, the project is non-warrantable, and buyers are pushed to portfolio and non-QM lenders: higher rates, bigger down payments, and a much shorter list of willing banks. The sequence that follows is well documented — a sale falls through at the questionnaire stage, the next listing sits, the price gets cut, and every appraisal in the building inherits the comp.

The scale is not hypothetical. By early 2025, Wall Street Journal reporting put Fannie Mae's internal list of ineligible and "unavailable" condo projects at more than 5,000 associations — up from a few hundred before the 2021 Surfside collapse — with roughly 1,400 in Florida alone. Reserves are only one trigger among several (insurance gaps and critical deferred maintenance are the others), but the reserve line is the one your board controls directly, every budget season.

One scoping note: this is a condominium rule. Project review applies to condos and co-ops; if your community is a planned development of detached homes — an HOA in the strict legal sense — lenders generally don't review your budget at all. The legal structure matters more than what your documents are called, and our guide to condo associations vs. HOAs shows how to tell which one you are.

Fannie Mae Condo Reserve Requirements Today: The 10 Percent Rule

The requirement lives in Fannie Mae Selling Guide section B4-2.2-02, the Full Review process: the lender must verify that the budget "provides for the funding of replacement reserves for capital expenditures and deferred maintenance that is at least 10% of the budget." The test the lender actually runs is one division:

• Reserve ratio = annual budgeted reserve allocation ÷ annual budgeted assessment income

The numerator is the contribution line in your adopted budget — the dollars the association plans to move into reserves this year for future capital replacements and deferred maintenance. It is not your reserve balance. That's the single most common confusion I see: a building holding $800,000 in its reserve account with a $0 contribution line in this year's budget fails the test, while a building with $40,000 in the bank and a healthy contribution line passes. Lenders are testing the habit, not the balance.

The denominator is annual budgeted assessment income — the regular common-expense fees owners pay. Several income streams are excluded before you divide: special assessment income, incidental income the project doesn't rely on for operations (clubhouse rentals, laundry, interest), and utility pass-throughs like bulk cable or internet. Excluding income shrinks the denominator, which helps your ratio — so read your budget's income section carefully before you compute.

Freddie Mac's Guide section 5701.5 imposes materially the same requirement for established projects. Both agencies find the number the same way: on the adopted annual budget your manager or treasurer attaches to the lender's condo questionnaire.

What Changed in 2026 — and What Changes January 4, 2027

Fannie Mae announced the overhaul in March 2026 with Lender Letter LL-2026-03, and it rolls out in stages. Four dates matter to a board:

• July 1, 2026 (in effect now): master insurance policies must cover at least 100 percent of the project's estimated replacement cost, and per-unit deductibles are capped at $50,000. The old inflation-guard requirement is gone.
• August 3, 2026: Limited Review is eliminated. Every conventional condo loan now runs through Full Review or a project-review waiver.
• August 3, 2026: the reserve-study alternative tightens — the budget must follow the study's highest recommended funding level, and baseline funding no longer qualifies (more below).
• January 4, 2027: the minimum reserve allocation rises from 10 percent to 15 percent of budgeted assessment income for loan applications dated on or after that day. Freddie Mac's Bulletin 2026-C mirrors the increase on the same date.

The Limited Review elimination deserves a moment, because it's why many boards have never felt the 10 percent rule bite. Under Limited Review, an attached unit in an established project outside Florida could close — at up to 90 percent loan-to-value for a primary residence — with no budget or reserve check at all. Community Associations Institute estimates roughly 40 percent of condo project reviews ran through that streamlined path. From August 3, it's closed. Even before the floor rises to 15 percent, far more of your building's sales will have the reserve line read, divided, and judged. A building that has been quietly non-compliant for years is about to find out.

The Escape Hatch: The Reserve-Study Path

You do not need 15 percent to stay warrantable. The alternative compliance path — in both agencies' guides — is a reserve study, with three conditions:

• Current: the study or a formal update must have been completed within three years of the loan application date.
• Complete: it must meet the agencies' content standards — a component inventory with condition assessments, remaining-life estimates, replacement costs, and a funding plan. That's the standard scope of a professional study, which typically runs $3,000 to $8,000; our reserve fund guide covers what to expect.
• Followed at the top level: as of August 3, 2026, your budget must fund reserves at the study's highest recommended funding level. Most studies model several scenarios — full funding, threshold funding, and a bare-bones baseline plan that lets the balance run to zero. Baseline is now explicitly disqualified; if your study presents three plans, lenders want your contribution matching the strongest one. Our comparison of straight-line vs. cash-flow funding explains those funding goals and why baseline plans carry no margin.

Notice what this path really is: a reserve-planning workflow. If a professional study recommends contributing 11 percent of assessment income because your components are young and your balance is strong, 11 percent keeps you warrantable — the study, not the blanket 15, becomes your number. For a large building, that can save tens of thousands of dollars a year, which covers the cost of the study several times over.

To document it, keep three things stapled together for lenders: the study with its completion date on the cover, the scenario page showing the highest recommended annual contribution, and the adopted budget with a reserve line that matches or exceeds it. If those numbers don't visibly connect, expect the underwriter to fall back to the 15 percent test. And check whether your state layers its own mandate on top — our state-by-state reserve study requirements guide covers which states require studies and how often.

Check Your Number Tonight: A Worked Example

Take Harborview, a 100-unit condominium charging $400 a month. Its adopted budget shows:

• Assessment income: 100 units × $400 × 12 = $480,000
• Clubhouse rental income: $6,000 — excluded from the denominator
• Special assessment for a lobby project: $60,000 — excluded from the denominator
• Contribution to reserves: $52,000

Harborview's ratio is $52,000 ÷ $480,000 = 10.8 percent. Today, that's warrantable. On January 4, 2027, it isn't: the budget needs $72,000 flowing to reserves — a $20,000 gap. There are two ways to close it, and they cost different amounts:

• Reallocate without raising dues. Cut $20,000 of operating spending and redirect it to the reserve line. The denominator doesn't move: $72,000 ÷ $480,000 = 15.0 percent. Done.
• Raise dues — and mind the moving denominator. New assessment dollars raise assessment income too, so you need more than $20,000. Solving ($52,000 + X) ÷ ($480,000 + X) = 15 percent gives X of about $23,500 — a 4.9 percent increase, or roughly $19.60 per unit per month.

That denominator effect surprises boards every time, and it's why "we'll just add the difference to dues" comes up short at the underwriter's calculator. Run your own budget through the same division tonight — it takes ten minutes.

Then ask the more important question: is 15 percent even enough? The Fannie and Freddie floor is a lending rule, not an adequacy standard — a 1980s high-rise with an aging elevator and an original roof may need far more than 15 percent, while a newer building may genuinely need less (which is exactly what the reserve-study path is for). Price your actual components against their remaining lives with our free reserve fund calculator, using realistic costs from the component library, and check your balance health with the percent funded calculator. Warrantability tests your contribution; percent funded tests your accumulated savings. A healthy building passes both.

Getting From 10 to 15 Without a Revolt

For a building at exactly 10 percent that closes the whole gap through dues, the same arithmetic works out to about a 5.9 percent assessment increase — $23.50 a month on a $400 assessment. Not nothing, but far from the four-figure special assessments that chronically underfunded buildings eventually levy. The sequencing matters more than the size:

• Fall 2026 budget season is the deadline that counts. A loan application dated January 10, 2027 is underwritten against the budget in effect that day — for calendar-year associations, the 2027 budget you adopt this October or November. Build the 15 percent in now; there is no phase-in on the lender's side.
• Split the move if you must. If a single jump is politically impossible, pair a partial dues increase with operating reallocations — trimmed landscaping scope, rebid insurance, deferred cosmetic projects — so the reserve line hits 15 without the full increase landing on owners at once. Our budget planning guide walks through where those trade-offs usually hide.
• Or buy the exception. If your components genuinely justify less than 15 percent, commission a study now — reserve firms book out 8 to 12 weeks in busy markets, and the study must be in hand, with your budget matching its top recommendation, before it protects a single sale. Between professional studies, an annual DIY update keeps the numbers current.
• Tell owners the real trade. Reserve contributions aren't spending — the money stays in the association's accounts. The honest framing for the annual meeting: $23.50 a month, or a building where buyers can't get a normal mortgage. Unit values are the stake, not the budget.

Florida boards have a painfully earned head start: buildings of three or more habitable stories already face mandatory structural reserve funding under the state's SIRS regime, which our Florida SIRS guide covers in detail. If SIRS has already pushed your structural funding up, you may be closer to 15 percent — or to a study-backed number — than you fear.

Questionnaires and Lender Letters: Keep Sales Moving

With Limited Review gone, every financed sale in your building triggers a condo questionnaire, and slow or incomplete answers stall closings as surely as a failed ratio does. Keep a current lender packet ready so any board member or manager can respond within days:

• The adopted annual budget, with the reserve contribution line clearly labeled — not buried in "miscellaneous transfers."
• The current reserve study and the scenario page your budget follows, if you're using the study path.
• Insurance declarations showing 100 percent replacement-cost coverage and deductibles within the $50,000-per-unit cap.
• A short written status on any open repairs, so "critical deferred maintenance" questions get answered with facts instead of silence.

Then recheck the ratio every budget season — assessment income grows, and a reserve line that was 15.2 percent of income two years ago quietly becomes 14.6 as dues rise around it. If you'd rather not maintain that math by hand, our Reserve Planner keeps your component inventory, funding plan, and contribution numbers in one place for $49 a year and recalculates as costs change — a useful companion between professional studies, though it doesn't replace them.

The boards that get hurt by January 4, 2027 will be the ones who hear about it from a title company mid-closing. You now have the formula, the dates, and the exception. Run the division this week, put the result in front of your board at the next meeting, and make this fall's budget the one that settles it.
