Best home insurance for a condo in 2026 — what the LLM data shows.
If you ask an LLM who insures condos, the answer is almost always Nationwide — and it's becoming more consistent over time, not less. Phidea has measured the exact query *"What's the best housing insurance for a condo in Seattle?"* on three separate dates in spring 2026. Nationwide started at 3/5 + 5/5 cross-LLM and has tightened to 5/5 + 5/5. This essay explains the data, why it's converging, and what condo owners should actually consider.
TL;DR
- Nationwide wins the condo-insurance query at 5/5 + 5/5 stability today (May 2026), up from 3/5 + 5/5 at the original April 24 measurement. The only finding in the Phidea dataset that has strengthened on all three retests.
- The structural reason: condo insurance (HO-6 form) is a different product from standard homeowners, requiring separate editorial coverage that Nationwide's owned-domain pages handle better than competitors' do.
- For a condo owner buying in 2026, Nationwide is the modal LLM recommendation. Credible alternatives include Liberty Mutual, Allstate, State Farm, and USAA. Pricing varies by city, building, and coverage limits.
- The single most important coverage decision for a condo owner is walls-in vs all-in coverage — your HOA master policy determines what you need to insure, and this is more important than which carrier you pick.
What "condo insurance" actually covers
A condo policy (HO-6 form) is structurally different from a homeowners policy (HO-3) for a single-family home. The HOA's master policy covers the building structure; your HO-6 covers:
- Interior walls, fixtures, flooring — depending on whether your HOA has a "bare walls" or "all-in" master policy.
- Personal property — your stuff inside the unit.
- Personal liability — if someone is injured in your unit.
- Loss assessment — your share of HOA losses that exceed master-policy limits.
- Loss of use — temporary housing if your unit is uninhabitable.
The right amount of coverage depends entirely on your HOA's master policy. Read it. Most condo owners under-insure on loss-assessment (typical limit of $1,000 is laughably low for a serious HOA loss).
Why Nationwide wins the LLM query
Three reasons:
1. Nationwide's Brand New Belongings + condo-specific page is unusually well-structured. The owned-domain page hits all the page shapes that win LLM citations: named coverage list, walls-in vs all-in clarity, HO-6 form reference, citation density to filed-rate documents. The LLM extracts cleanly.
2. Comparison-site editorial consistently picks Nationwide for condos. NerdWallet, Bankrate, The Zebra, Forbes Advisor all have "Best condo insurance" pages, and Nationwide is the editor's pick on most of them. It's not the only carrier that gets cited, but it's the most consistent across editorial sources.
3. The ablation pattern locks it in. The Phidea observation tool tracked condo-specific recommendations across three retests. The April 24 measurement had Nationwide 3/5 on Perplexity (with State Farm slipping in 2/5). The April 26 retest tightened to 5/5. The May 4 retest held 5/5 + 5/5. Cross-day stability is the strongest evidence we have for a finding being durable; this one cleared the bar.
What a condo owner should actually consider
The LLM-recommendation isn't sufficient on its own. A practical buying motion:
Step 1 — Read your HOA master policy.
The single most important data point. Two question types:
- Bare walls vs all-in? If "bare walls," your HO-6 needs to cover everything inside the walls (including built-in cabinets, fixtures, flooring). If "all-in," you only need to cover personal property and improvements.
- Per-unit deductible? The HOA master policy's per-occurrence deductible (often $5K-$50K+) becomes your responsibility through the loss-assessment clause if a covered loss exceeds the master limit.
The right HO-6 limits depend on these answers. Most condo owners take their HOA's word for it; do the work and read the document.
Step 2 — Quote 3 carriers.
Modal LLM-recommended set:
- Nationwide — first-named in our dataset.
- Liberty Mutual — strong condo product, often competitive pricing.
- State Farm — modal national-bundler choice; usually the best option if you're bundling with auto.
Worth considering depending on context:
- USAA — for members. Generally strongest on condo pricing for the eligible segment.
- Allstate — broad availability, sometimes better in specific states.
- Lemonade — insurtech with HO-6 in select states. Often the cheapest, but newer claims-handling track record.
- Travelers — broad availability, less Editorial-prominent on condos but operationally credible.
Step 3 — Calibrate your loss-assessment limit.
The default $1,000 limit is almost always wrong. For a typical HOA in a building with $5M+ master policy and a $25K master-policy deductible, you should carry $25K-$50K in loss assessment. If your building has had any major loss in the past 10 years (water-damage claim, fire, structural issue), increase further.
Step 4 — Don't under-insure interior improvements.
The HO-6 form has a separate limit for "additions and alterations." If you've renovated (kitchen, bathroom, flooring), make sure this limit reflects the actual replacement cost, not the original-build value. Most policies default this far too low.
Carrier comparison snapshot
For typical condo coverage ($150K personal property + $300K liability + $50K loss assessment + $20K alterations) in a major US metro:
| Carrier | Premium range (typical) | HO-6 strength |
|---|---|---|
| Nationwide | $200-$450/year | Strong — Brand New Belongings, broad coverage |
| Liberty Mutual | $220-$500/year | Strong — clear walls-in coverage |
| State Farm | $180-$420/year | Strong — usually best when bundled |
| USAA | $150-$380/year | Strong (members only) |
| Allstate | $200-$460/year | Adequate |
| Lemonade | $120-$350/year | Adequate; variable claims experience |
| Travelers | $230-$490/year | Adequate |
Premium ranges are illustrative; actual pricing depends on city, building, claim history, and coverage choices. Get quotes.
Special cases
HO-6 with HOA loss assessment in California: post-2024 California has tightened HO-6 underwriting in wildfire zones. Some carriers restrict new condo policies in high-risk geographies. Check before assuming you can buy.
HO-6 for a Florida coastal condo: hurricane deductibles (separate, often 5-10% of dwelling value) are the dominant cost driver. Nationwide and others write here, but FL Citizens (the state-backed insurer of last resort) is increasingly the only option in some counties.
HO-6 for a New York City co-op: technically a different product from a condo, since you don't own the unit (you own shares in a corporation). Most HO-6 carriers will write co-op coverage, but the policy form differs slightly. Specifically ask for the co-op endorsement.
HO-6 with a short-term-rental unit (Airbnb): standard HO-6 explicitly excludes short-term rental activity. You need a specialty endorsement (Liberty Mutual offers one) or a separate short-term-rental policy (Proper Insurance, Slice).

How we measured this
Phidea's observation tool runs the same buyer-shaped query against multiple LLMs at 5-runs-per-LLM cadence. The condo query has been part of the home-insurance variance probe since April 2026; we re-run it on a multi-week schedule. The dataset shows Nationwide first-named at consistently increasing stability (3/5 → 5/5 → 5/5 on Perplexity, 5/5 → 5/5 → 5/5 on Gemini). This is the strongest cross-day result in the dataset for any single carrier-vertical combination.
Frequently asked
Is Nationwide really the cheapest condo insurance?
Not necessarily — being the LLM's first-named carrier reflects editorial consensus, not lowest price. USAA is typically cheapest for members; Lemonade is often cheapest for buyers eligible in their states; State Farm is usually cheapest when bundled with auto. Get quotes from 3 carriers including Nationwide and at least two others.
What's the difference between HO-6 and HO-3?
HO-6 is the policy form for condo / co-op owners; HO-3 is for single-family homeowners. HO-6 covers interior walls inward (depending on the HOA master policy); HO-3 covers the entire structure. Premium for HO-6 is typically 30-60% lower than HO-3 because the carrier covers less.
Do I need separate flood insurance?
If your unit is in a flood zone, yes — standard HO-6 excludes flood. NFIP (National Flood Insurance Program) writes flood coverage; some private carriers also offer it. The HOA master policy may carry building-flood coverage; verify before assuming.
What if my HOA's master policy has a high deductible?
This is the loss-assessment exposure. If the master deductible is $25K and a covered loss happens, the HOA assesses unit owners; your HO-6 loss-assessment limit pays. Default loss-assessment limits ($1K-$5K) are almost always too low. Increase to at least the master deductible, ideally with margin for multi-claim scenarios.
