Arlington condo buyer reviewing a building's master insurance certificate and association documents before closing

Can an Arlington Condo Building’s Insurance Stop Your Loan From Closing?

Yes. Since July 1, 2026, Fannie Mae has required that a condo building’s master property insurance policy carry a per-unit deductible of no more than $50,000, and that its coverage amount equal at least 100% of the building’s estimated replacement cost. If your building misses either mark, your lender can decline the loan no matter how strong your own file is. You’ll also need your own HO-6 unit owners policy any time the master policy carries a per-unit deductible — and the minimum amount isn’t your choice.

Here’s the part of an Arlington condo purchase that catches people completely off guard.

You can have a 780 credit score, 25% down, and an underwriting file your loan officer calls boring in the best possible way — and still lose the deal over a document you never signed. The building’s insurance policy.

In March, Fannie Mae published Lender Letter LL-2026-03, a coordinated set of updates issued in alignment with Freddie Mac and in coordination with FHFA. Most of the industry attention went to the project-standards half of that letter — the reserve requirements, the retirement of the Limited Review process. The insurance half got far less coverage, and it’s the half that’s already binding on a loan you’d write today.

The Three Insurance Numbers Your Lender Now Checks

Your lender isn’t only underwriting you. It’s underwriting the building, and the master property insurance policy has to clear three specific thresholds.

Coverage has to equal at least 100% of replacement cost. The master policy amount must equal at least 100% of the estimated replacement cost value of the project improvements — common elements and residential structures both. Fannie Mae retired the old documentation requirements here, so a guaranteed or extended replacement cost policy, a replacement cost estimate from the insurer, or the project’s insurance risk appraisal all work as proof.

The per-unit deductible can’t exceed $50,000. This is the new one, and it’s the one most likely to blow up a deal. Associations under premium pressure have a standard move: raise the deductible, hold the premium down. Fannie Mae just put a ceiling on how far that move can go. Lenders were encouraged to implement it immediately, and required to do so for all loan applications dated on or after July 1, 2026.

The per-occurrence deductible can’t exceed 5% of the coverage amount. And if the policy carries separate deductibles for individual perils — windstorm, for example — each one has to clear the limit on its own, not just the policy average.

A building that’s over the line isn’t automatically dead. Fannie Mae accepts a deductible buy-back policy purchased by the association to meet the maximum deductible requirement, provided that policy satisfies the rest of the property insurance rules. That’s a real fix. It also takes a board decision and, usually, a renewal cycle — which is not the same thing as a phone call during your financing contingency.

You Probably Need an HO-6 Now, and the Amount Isn’t Up to You

Under the updated rules, you’re required to carry a unit owners property insurance policy — the HO-6 — in either of two situations:

  • Any portion of the interior of the unit, or improvements to it, isn’t covered by the master policy, or
  • The master policy includes a per-unit deductible

That second trigger is the one that changed the math for a lot of buyers. If the building carries a per-unit deductible at all, the HO-6 is no longer optional, and its minimum coverage amount has to be at least the greater of:

  • An amount sufficient to restore the interior of the unit and its improvements to pre-loss condition, for anything the master policy doesn’t cover, or
  • The amount of the per-unit deductible

So if your building’s master policy has a $25,000 per-unit deductible, your HO-6 needs at least $25,000 of coverage — even if the interior of your Virginia Square one-bedroom would cost less than that to rebuild. Your own deductible on that policy is capped too: it can’t exceed the greater of 5% of the coverage amount or $2,500. And the HO-6 has to be written on a replacement cost basis.

None of this is expensive relative to the purchase. All of it is the kind of thing that surfaces eleven days into a thirty-day close if nobody looked earlier.

Where Arlington Buildings Actually Run Into Trouble

Arlington’s condo stock skews vertical. Rosslyn, Crystal City, Pentagon City, and the Ballston-to-Courthouse corridor are full of buildings running central heating and cooling plants rather than in-unit systems — and Fannie Mae requires Boiler and Machinery/Equipment Breakdown coverage for any project with central heating or cooling, in an amount equal to the lesser of $2 million or the replacement cost value of the buildings housing that equipment. The older mid-rises with an aging central plant are exactly the buildings where this coverage matters most and is easiest to have quietly lapse.

There’s also a Virginia wrinkle worth understanding. Under § 55.1-1963 of the Virginia Condominium Act, the condominium instruments may require the association to obtain a master casualty policy at full replacement value and a master liability policy. The obligation comes from the building’s own recorded documents — not from the statute itself. Virginia is a caveat emptor state, so the seller’s disclosure isn’t going to do this work for you. Reading the instruments and the building’s reserve study is how you find out what your association is actually on the hook to carry.

One useful lever most buyers never use: § 55.1-1963(C) requires that whenever a policy is obtained, changed, or terminated, written notice goes promptly to every unit owner. If the association switched carriers or raised the deductible at last renewal, a notice went out. Ask the seller for it.

And one change that cuts both ways — Fannie Mae retired the requirement that roofs be insured on a replacement cost basis. Roofs still have to be insured; they just don’t have to be insured for what it costs to replace them. That flexibility helps associations buy affordable coverage in a hard market. It also means an actual-cash-value settlement on a twenty-year-old roof can leave a funding gap that owners cover through reserves or a special assessment. Read it alongside the reserve study, not in isolation.

If any of that sounds like it overlaps with the broader warrantability question, it does — the insurance rules are one piece of the same Fannie Mae condo standards that govern Arlington purchases. A building can have healthy reserves and still fail on insurance, or vice versa. Lenders check both.

What to Ask For Before Your Review Period Runs Out

The insurance certificate arrives in the resale package — the disclosure packet the association delivers. Your review period for that package is a negotiable contract term, not a fixed statutory deadline. The standard Virginia contract has a blank for the number of days; leave it blank and it defaults to three. And here’s a quirk worth knowing: even if the contract specifies zero days, you still have until 9:00 PM on the day you receive the documents to cancel. Plan your review around that, not around an assumption that you have a week.

What to request, ideally before you’re under contract:

  • The evidence of property insurance or ACORD certificate, showing the coverage amount, the per-occurrence deductible, and the per-unit deductible
  • Confirmation that the policy is written on a replacement cost basis
  • Whether the association carries a deductible buy-back policy
  • Confirmation of equipment breakdown coverage if the building has a central plant
  • The most recent insurance notice sent to owners under § 55.1-1963(C)
  • The last two annual budgets and the current reserve study

Then hand all of it to your loan officer before your financing contingency date, not after. Most of the deals I’ve seen die on this die because the certificate showed up late and nobody read the deductible line until the appraisal was already back.

The buildings that clear all of this without a second thought and the buildings that don’t are often two blocks apart in the same neighborhood. That’s not something you can filter for on a listing site — it’s building-level knowledge, and it’s the difference between an offer that closes and an offer that costs you an inspection fee and five weeks.

Frequently Asked Questions

Can a lender really deny my loan because of the condo building’s insurance?

Yes. Conventional lenders selling loans to Fannie Mae or Freddie Mac have to confirm the building’s master policy meets the coverage, deductible, and peril requirements — this is separate from your personal credit and income underwriting. If the building’s policy is out of compliance and the association won’t or can’t fix it, the loan doesn’t close, regardless of how strong your file is.

How much HO-6 coverage do I need for an Arlington condo?

At least the greater of two amounts: enough to restore your unit’s interior and improvements to pre-loss condition for anything the master policy doesn’t cover, or the full amount of the master policy’s per-unit deductible. Your own deductible on that HO-6 can’t exceed the greater of 5% of the coverage amount or $2,500, and the policy has to be written on a replacement cost basis.

What happens if the building’s per-unit deductible is over $50,000?

The association can bring the policy back into compliance at renewal, or it can purchase a deductible buy-back policy — Fannie Mae accepts that as a way to meet the maximum deductible requirement, as long as the buy-back policy satisfies the other property insurance rules. Neither happens on your timeline, so find out early enough to either work the problem or walk.

Does Virginia law require my condo association to carry insurance?

Not by itself. Under § 55.1-1963 of the Virginia Condominium Act, the condominium instruments may require the association to obtain a master casualty policy and a master liability policy — the mandate comes from the building’s own recorded documents. The Act does separately require any association collecting assessments to maintain a fidelity bond or employee dishonesty policy.

Do these rules apply to FHA and VA loans too?

No. These specific requirements come from Fannie Mae, aligned with Freddie Mac, and govern conventional financing. FHA and VA run their own condo project approval processes with their own insurance standards — so if you’re using one of those programs, confirm with your lender which rule set applies to your building. Our guide on using a VA loan for an Arlington condo covers that path in more detail.

The Bottom Line

The insurance page of a resale package is three or four lines long, and it decides whether your loan funds. Coverage at 100% of replacement cost, a per-unit deductible at or under $50,000, a per-occurrence deductible at or under 5% — and an HO-6 sized to whatever that per-unit deductible turns out to be.

Which Arlington buildings clear that comfortably, which ones are one renewal away from a problem, and which ones already have a buy-back policy in place is exactly the kind of thing I track building by building. It doesn’t show up in a listing description.
