Florida Condo Master Insurance Deductibles and Mortgage Approval

A Florida condo can look affordable until the lender reviews the association's master insurance policy. A large deductible can create a project-level financing problem even when the buyer has strong credit, stable income, and enough money for closing.

The deductible is the amount that must be absorbed before the insurer pays a covered claim. In a condo project, that exposure may sit with the association, the unit owners, or both, depending on the policy and governing documents.

Do not wait until final underwriting to find out how the deductible works. Florida policies can separate windstorm, named-storm, and other peril deductibles. Each relevant deductible and the method used to calculate it need to be reviewed.

Why the Master Policy Matters to the Mortgage

A condo mortgage is secured by one unit, but that unit depends on the project's buildings and common elements. If the association's insurance leaves too much loss exposure, the lender must determine whether the project satisfies the applicable loan program and investor rules.

Fannie Mae's current Selling Guide requires a condo master property insurance policy for common elements and residential structures unless the project's legal documents require individual property policies for each unit. When a master policy is required, the lender or servicer must verify that it covers both.

Insurance approval is not the same as borrower approval. A borrower can qualify while the project remains ineligible, incomplete, or subject to more documentation.

Fannie Mae's Current Master Deductible Limits

Fannie Mae updated its project insurance guidance effective August 5, 2026. Under the current guide, the maximum allowable per-occurrence deductible for required property insurance perils is 5% of the master property insurance coverage amount.

If the policy uses a per-unit deductible, the current maximum is $50,000 per unit. When a master policy has a per-unit deductible, Fannie Mae also requires the borrower to maintain a unit owners property insurance policy under its individual-unit rules.

Separate deductibles do not get blended into one easy answer. Fannie Mae says that when a policy has different deductibles for required perils, such as windstorm or wildfire, each deductible must satisfy the applicable maximum.

A deductible buy-back policy purchased by the association may help meet Fannie Mae's maximum deductible requirements, but only if that policy satisfies the other applicable property insurance requirements. That is an underwriting review, not an automatic cure.

Why a Percentage Deductible Needs Real Math

A percentage on the declarations page does not tell you the dollar exposure by itself. The reviewer needs to know what amount the percentage applies to.

For example, 5% of the total master coverage amount is different from 5% of one building's insured value. It is also different from 5% of a unit's value. The policy language, schedules, endorsements, and deductible basis control the calculation.

That is why a verbal answer such as "the hurricane deductible is 5%" is incomplete. The lender needs the actual policy documents and the resulting dollar amount.

Per-Occurrence and Per-Unit Deductibles Are Different

Per-occurrence deductible

A per-occurrence deductible generally applies to a covered event under the master policy. For Fannie Mae's current project rule, the maximum is measured against the master property insurance coverage amount.

Per-unit deductible

A per-unit deductible assigns a stated deductible to each affected unit. Fannie Mae's current maximum is $50,000 per unit, and the borrower must carry qualifying unit-owner coverage when the master policy has this structure.

The association's declarations, policy form, schedules, and endorsements should make the structure clear. If they conflict or use vague language, the lender may need clarification from the carrier or qualified insurance professional.

How the HO-6 Policy Fits In

The buyer's unit-owner policy, often called an HO-6 policy, does not automatically repair every master-policy issue. It has its own required coverage, deductible, loss-settlement, and documentation standards.

Under Fannie Mae's current individual-unit guidance, a borrower must have unit-owner coverage when the unit interior or improvements are not fully covered by the master policy, or when the master policy has a per-unit deductible. The minimum coverage must account for the uncovered interior or improvements and, when applicable, the amount of the per-unit deductible.

For required perils, Fannie Mae says the maximum deductible on the unit-owner policy is the greater of 5% of that policy's coverage amount or $2,500. The unit-owner policy must also cover a required peril when the master policy applies a per-unit deductible to that peril.

An insurance agent can explain coverage and price. The lender still has to determine whether the complete package satisfies the mortgage rules.

Documents to Request Early

The complete master property insurance policy, not only a one-page certificate.
Current declarations and all deductible schedules.
Windstorm, hurricane, named-storm, flood, and other applicable endorsements.
A schedule of buildings, locations, values, and coverage limits.
Replacement-cost support or an insurance valuation used by the association.
The association's governing documents showing who insures the unit interior and improvements.
The proposed HO-6 policy and evidence of its coverage amount and deductible.
Any deductible buy-back policy and evidence that it is active.
Written carrier or agent clarification if the deductible basis is not obvious.
Association budget, reserves, meeting minutes, and assessment notices when the deductible could create a funding concern.

A certificate of insurance may confirm that a policy exists, but it may not show enough detail to calculate the deductible or verify coverage sufficiency.

Red Flags for Florida Condo Buyers

The master policy is available, but the deductible endorsement is missing.
The association quotes a percentage without identifying the amount used for the calculation.
The policy has separate wind or named-storm deductibles that were not reviewed.
The master deductible is described as per unit, but the buyer's proposed HO-6 coverage does not address it.
The association relies on a buy-back policy that has expired or cannot be documented.
The insured value appears stale or the replacement-cost support is unavailable.
The certificate, declarations, questionnaire, budget, and governing documents give inconsistent answers.
The association has limited reserves and no clear plan for funding a large deductible after a claim.

A red flag does not prove the condo is unfinanceable. It means the file needs facts before anyone makes that call.

What Buyers Should Do Before Contract Deadlines Tighten

Tell the loan officer that the property is a condo and provide the exact project name, phase, building, address, and unit.
Ask for the full master insurance package as soon as the property is under serious consideration.
Have the lender identify the intended loan program and project-review path.
Ask whether each required-peril deductible has been calculated and documented.
Confirm whether the master policy uses a per-occurrence or per-unit deductible.
Get an HO-6 quote based on the actual master policy and governing documents, not a generic assumption.
Keep financing, condo-document, inspection, and legal-review protections appropriate for the transaction. Get contract advice from a qualified Florida attorney.
Do not assume another lender or loan program will ignore the same insurance issue.

Can Another Loan Program Work?

Possibly, but do not treat a program change as a guaranteed workaround. Fannie Mae, Freddie Mac, FHA, VA, portfolio, and non-agency loans can use different project and insurance requirements. Lenders may also apply overlays beyond published minimums.

A realistic comparison requires the borrower, unit, occupancy, project, policy, deductible structure, and complete documentation. Changing programs can also affect down payment, pricing, reserves, appraisal, and closing time.

How This Connects to the Rest of the Condo Review

Insurance is one part of project eligibility. Deductible exposure can connect to reserves, special assessments, deferred maintenance, and the association's overall finances.

Questions to Ask Your Loan Officer

Do you have the complete master policy and deductible endorsements?
What is the deductible basis and calculated dollar amount for each required peril?
Does the policy use a per-occurrence or per-unit structure?
Is an HO-6 policy required, and what coverage amount must it show?
Is the project insurance review complete, conditional, or still missing documents?
Does the intended loan program have a different requirement than another option?
Which contract date is at risk if the carrier or association responds late?

The Bottom Line

A master insurance deductible can stop or delay a Florida condo mortgage when the number, structure, or supporting documents do not satisfy the applicable rules. The percentage alone is not enough. Get the full policy, calculate the real exposure, confirm any unit-owner coverage, and finish the project review early.
