Fannie Mae's Condo Overhaul: A Cheat Sheet for Realtors and Buyers

On March 18, 2026, Fannie Mae dropped Lender Letter LL-2026-03 — the most significant overhaul of condo project standards and insurance requirements since the post-Surfside tightening. Some of it is in effect right now. Some kicks in this August. The biggest reserve change lands in January 2027.

Below is the version your agent partners and buyers can actually use — what changed, when it takes effect, and what to do about it. We're not covering every footnote (the full Lender Letter is linked at the bottom). We're covering the parts that move deals.

The big-picture take

Fannie Mae is pulling two levers at once:

• Loosening the rules around which projects can be financed — smaller buildings, Florida attached condos, investor-heavy projects, simpler insurance documentation.
• Tightening the rules around financial health of bigger condo projects — higher reserves, stricter reserve-study requirements, no more Limited Review.

Translation: more buildings become financeable, but the financially weak ones are about to get flagged faster than ever.

Already in effect (since March 18, 2026)

Waiver of Project Review expanded to small buildings

Projects with 10 or fewer units — new or established — can now skip the full project review entirely. 5-to-10-unit projects must not be part of a master association or larger development. This is huge for Philadelphia rowhome conversions and small boutique buildings.

Florida PERS review retired for new attached condos

New or newly converted Florida projects with attached units no longer require submission to Fannie Mae's Project Eligibility Review Service. They now flow through the standard lender-delegated Full Review like every other state. Faster approvals on new construction.

50% investor concentration cap is gone

The rule that capped investor ownership at 50% in established projects (when underwriting an investor loan via Full Review) is retired. Note: the presale rule — at least 50% of units conveyed or under contract to primary or second-home buyers in new and newly converted projects — still applies.

Insurance simplifications (1–4 unit and master policies)

• No more replacement-cost-value documentation for 1-to-4-unit properties and master policies — if the policy provides replacement cost coverage, it's deemed sufficient.
• Roofs no longer need to be insured on a replacement cost basis — they just need to be insured.
• Inflation guard coverage no longer required on master policies for project developments.

Individual unit-owner policy deductible cap

The max allowable deductible on an individual (HO-6) unit owner policy is now the greater of 5% of coverage or $2,500. Lower-cost coverage options become viable for owners getting hammered on premiums.

Coming July 1, 2026

$50,000 per-unit deductible cap on master policies

Master property insurance policies can carry a per-unit deductible up to $50,000. When a master policy has a per-unit deductible, the unit owner must carry an individual policy to cover it — important to flag for buyers in buildings with high master deductibles.

New individual unit-owner policy framework

Fannie Mae replaced the full rulebook on when an individual policy is required and how much coverage is enough. Two-bullet version: a borrower must carry an individual policy if any interior or improvement isn't covered by the master, or if the master has a per-unit deductible. Coverage must equal the greater of (a) what's needed to restore interior/improvements not covered by master, or (b) the per-unit deductible amount.

Coming August 3, 2026

Limited Review is dead

The Limited Review process — the lighter-touch review that many established condos used to flow through — is retired. Established projects must now go through Full Review or the (newly expanded) Waiver of Project Review. The remaining Florida-specific geographic restrictions also disappear with this change.

For agents: pre-Aug 3, you can still use Limited Review on loans dated before that. Post-Aug 3, every established condo loan needs the Full Review documentation package — HOA questionnaire, budget, reserve study where applicable, insurance certs.

Enhanced reserve study requirements

When lenders use a reserve study to demonstrate a project has sufficient reserves, the budget must include the highest recommended reserve allocation from the study. The baseline funding method (which let reserves approach but not fall below zero) is no longer allowed. Studies need to fully fund projected capex, not just barely break even.

Coming January 1, 2027 (servicer side)

Annual insurance reminder to borrowers

Servicers must remind borrowers at least annually to review their property insurance coverage with their carrier. Mostly invisible to buyers, but it's a real new requirement.

Lender-placed insurance trigger updates

Servicers must place force-placed coverage when the existing policy is being cancelled, non-renewed, or lapses. Cleaner rules around when this happens.

Coming January 4, 2027

Reserves jump from 10% to 15%

This is the headline number. The reserve allocation requirement for capital expenditures and deferred maintenance goes from 10% to 15% of the annual budgeted income assessment for Full Review projects. Projects currently budgeting at 10% have ~7 months from now to get their financials in line if they want to remain financeable in 2027 and beyond.

If you've got a listing in a building that's been coasting on a 10% reserve allocation, talk to the HOA board now. Special assessment or dues bump in 2026 is much easier than a deal falling apart in February 2027 because the budget doesn't qualify.

What this means for realtors

• Small buildings became a lot easier. 5–10 unit projects — common in Philly, Bryn Mawr, Manayunk, Cherry Hill — now skip the full project review. Faster approvals, fewer dead deals.
• Florida is open again on new attached projects. If you have clients buying a beach condo down south, the PERS bottleneck is gone.
• Investor-heavy buildings are unlocked. Established condos with above-50% investor ownership are no longer disqualified for investor loans. Big for Center City rentals.
• Aug 3 is your deadline for Limited Review. If you have a deal in a borderline building and the loan dates pre-Aug 3, the lighter review is still on the table. After that, full diligence on every established condo.
• Buildings with weak reserves are the new risk zone. Start asking about reserve allocations on every listing. A 10% reserve building works today but won't on Jan 4, 2027. Plan ahead.

What this means for buyers

• Insurance just got cheaper to comply with. Higher individual deductibles allowed, simpler documentation. Net effect: easier to get a policy that meets Fannie Mae's bar.
• Small-building condos are back on the menu. If you've been looking at a 6-unit boutique conversion that was getting kicked out at underwriting, get re-pre-approved.
• Watch the master deductible. If a building has a $50K per-unit master deductible, you'll need an HO-6 policy that covers that gap. Ask before you write the offer.
• If you're looking at a larger building, ask about the reserve allocation. Anything under 15% of annual budget will be a problem starting Jan 4, 2027 — including for the resale of your unit later.

Bottom line

Fannie Mae is making it easier to finance the right condos and harder to finance the wrong ones. Smaller, well-run buildings just got a green light. Mid-size and large buildings with weak financials have 7 months to fix their reserve picture before the January 2027 changes take hold.

If you have a specific listing, building, or buyer scenario you want us to look at against the new rules, ping any banker on the team — we can pull the project file, model it against the Full Review and Waiver criteria, and tell you whether it works today, August, and January 2027.
