HO-3 vs. HO-5 With Replacement Cost vs. ACV: Which Policy Fits Your Home Value, Flood Zone, and Claim History Before Auto-Renewal?

Your renewal notice just arrived. The premium went from $2,360 to $2,640. The policy form says "HO-3." The roof line says "ACV." Flood isn't mentioned anywhere. Before you pay it, ask one question: if something big happened next month, what would this policy actually pay me, and how much would I owe on top of it?

I spent years reviewing policies, and the most expensive mistakes I see aren't about the premium. They come from treating two separate decisions as one. Below is how to separate them and run the numbers with your own inputs.

A note on method. The framework draws on Veloqua's analysis of 11,449 data points across eight sources, including NAIC state premium data (our naic-state-premiums set has 2,550 rows), III state benchmarks (1,071 rows), FEMA National Risk Index peril data (306 state-peril rows), and ISO-style discount factors (1,020 rows). The dollar figures in the worked examples are modeled illustrations built from rounded inputs, not quotes. Swap in your own numbers.

What This Week's Headlines Mean for Your Renewal

Flood is the biggest blind spot. Insurance Journal's "Takeaways From AP Analysis on the Flaws in National Flood Insurance" reports that just 2.4% of properties nationwide are covered by 4.5 million federal flood policies. That is happening while climate change pushes flood risk higher. Neither an HO-3 nor an HO-5 covers flood, so most homeowners are relying on a policy that excludes it by design.

Reverse mortgage borrowers have extra exposure. HousingWire's July HECM broker rankings, "HECM broker endorsements for July show the same players dominating the market," note that Atlantic Avenue topped 1,000 loans on a 12-month rolling total. Endorsements overall are tracking toward their weakest year since 2003. Fewer people are taking these loans, but those who do are 62 or older, often in older homes. They must keep homeowners insurance in force or risk default, so a coverage mistake there is also a loan problem.

Carrier headlines aren't coverage changes. Insurance Journal's leadership news covered AIG naming a new chief risk officer, Plymouth Rock Home naming a VP of customer service and underwriting, and Allianz reshuffling two CEO seats. None of that rewrites your contract. I don't recommend insurers. Your declarations page and policy form are what pay claims, so that's what to review.

HO-3 vs. HO-5 Is Not the Same Decision as Replacement Cost vs. ACV

Here's the plain-English version:

HO-3 is the standard homeowners policy. The house itself is covered for any cause not specifically excluded ("open perils"). Your belongings are covered only for listed causes such as fire, theft, and windstorm ("named perils").
HO-5 is the premium version. It covers both the house and your belongings for any cause not excluded. It usually pays replacement cost on belongings.
Replacement cost (RC) pays what it costs to repair or replace with new materials, with no deduction for age.
Actual cash value (ACV) pays replacement cost minus depreciation.

The form (HO-3 or HO-5) controls what causes are covered. The payout basis (RC or ACV) controls how much you get. You can have an HO-3 with replacement cost on the dwelling and an ACV schedule on the roof. You can also have an HO-5 with a surprise exclusion. Read the declarations page for both.

Setup	Dwelling paid at	Belongings paid at	Belongings covered for	Modeled added cost vs. cheapest option (on a $2,400 base)
HO-3, ACV on everything	ACV	ACV	Named perils	Baseline
HO-3, RC dwelling, ACV belongings	RC	ACV	Named perils	+$100 to $250/yr
HO-3, RC dwelling plus RC belongings endorsement	RC	RC	Named perils	+$150 to $300/yr
HO-5	RC	RC	Open perils	+$200 to $400/yr

This is the kind of side-by-side Veloqua runs for you, so you don't have to build the spreadsheet yourself. For a deeper dive on one house, see our HO-3 vs. HO-5 payout math on a $400K house.

Worked Example 1: The $28,000 Roof

Hail damages a 15-year-old roof. Replacement cost is $28,000. The roof has a 25-year expected life, and your deductible is $2,500.

ACV payout:

Depreciation: 15 ÷ 25 = 60%
ACV of the roof: $28,000 × 40% = $11,200
Check after deductible: $11,200 − $2,500 = $8,700
Your out-of-pocket cost: $28,000 − $8,700 = $19,300

Replacement cost payout:

Check: $28,000 − $2,500 = $25,500
Your out-of-pocket cost: $2,500

The payout gap is $16,800, and it comes entirely from the valuation basis. It has nothing to do with HO-3 vs. HO-5. If your roof is over 10 to 15 years old, many policies move it to an ACV schedule. This is the first line I'd check on any renewal.

Worked Example 2: Does the HO-5 Upgrade Pay for Itself?

Suppose you own $90,000 of belongings, and a total fire loss on an HO-3 pays ACV on contents. At roughly 50% average depreciation, you'd collect $45,000 instead of $90,000. That's a $45,000 gap.

The HO-5 costs $300 more per year. The break-even is:

$300 ÷ $45,000 = 0.67% per year (about 1 in 150)

Now compare it to a planning assumption for a major contents-affecting loss. I'll use 0.3% per year, which is a rough assumption, so use your own:

0.003 × $45,000 = $135/year of expected benefit against $300 of cost.

On expected value alone, a full HO-5 is a loser for a typical household. Insurance still makes sense here because it covers a hole you couldn't absorb, not because the math wins. It also means the cheaper middle option matters. An RC-on-belongings endorsement at about $150/year closes most of that gap at roughly break-even cost.

The decision flips as your belongings value rises. At $150,000 of contents, the gap is about $75,000 and the break-even drops to 0.4% per year. Add jewelry, art, instruments, or equipment and the full HO-5, plus scheduled items, starts to make sense.

Worked Example 3: When Your Dwelling Limit Is 30% Short

Many policies with replacement cost carry a condition, often 80%, that your dwelling limit be at least that share of the rebuild cost, not the market value. Say your rebuild cost is $400,000, but you carry $280,000.

Required: 80% × $400,000 = $320,000
Ratio: $280,000 ÷ $320,000 = 0.875
On a $50,000 partial loss: ($50,000 × 0.875) − $2,500 deductible = $41,250 paid, leaving about $11,250 with you
On a total loss, the limit is $280,000 against a $400,000 rebuild: $120,000 short (30% underinsured)

This is why I say replacement cost only helps if the limit it applies to is realistic. An "extended replacement cost" add-on of 25% or 50% above the limit is a cheap cushion. The details are in our guide to adjuster underpayment on older homes.

You can model your own limit and rebuild cost at Veloqua, including the 80% condition.

The Flood Gap Neither Policy Closes

The AP analysis is a reminder that flood sits outside both forms. Under the National Flood Insurance Program, the caps are $250,000 for the building and $100,000 for contents, and contents are paid at ACV. Policies generally have a 30-day waiting period before they take effect.

On a $420,000 rebuild in a high-risk zone:

Structure: $420,000 − $250,000 = $170,000 gap in a total loss
Contents: ACV only, so the same depreciation math from Example 2 applies

FEMA's high-risk zones are defined by a 1% annual chance of flooding. Over a 30-year mortgage:

1 − 0.99³⁰ ≈ 26% chance of at least one such flood

I'm not trying to scare anyone. Most homes in these zones won't flood in a given year. But 26% is a real number to weigh against a flood premium that's often several hundred to a couple thousand dollars a year, depending on zone and elevation. Pull a quote before deciding. We cover the structure-vs-limit problem in our guide on the NFIP limit vs. actual rebuild cost.

Our state-peril-risks data (306 rows from the FEMA National Risk Index) is a good starting point for seeing which perils dominate in your state.

If You Have a Reverse Mortgage (HECM)

HECM borrowers face a few particular issues:

Insurance lapse is a default trigger. Pick a deductible you can pay from cash without missing a premium. A $5,000 deductible on a fixed income can be a worse deal than a $1,000 deductible at a higher premium.
Older homes tend to carry ACV roof schedules. The $16,800 gap in Example 1 comes straight out of your equity, which is the asset the loan is already drawing on.
Flood insurance is required in mapped high-risk zones. Check that the limit matches your actual rebuild cost, not just the lender's minimum.

HousingWire's data shows the HECM market is shrinking toward its smallest year since 2003. For those who still borrow, the insurance side deserves a closer look than it usually gets.

Which Setup Fits You? Match It to Your Variables

Your situation	What to lean toward	Why
Roof 15+ years, hail-prone state	Replacement cost on the roof, or budget to replace it	$16,800 gap in Example 1
Belongings under $60K, no big collectibles	HO-3 plus RC belongings endorsement	Near break-even in Example 2
Belongings $100K+ or collectibles	HO-5 plus scheduled items	Gap of $45K to $75K+
Dwelling limit hasn't changed in 3+ years	Re-run the rebuild estimate	30% underinsurance in Example 3
Flood zone or low-lying lot	Separate flood policy sized to rebuild cost	$170K structure gap
Claim in last 5 years	Check HO-5 availability and surcharge before shopping	Some carriers restrict options
Fixed income or reverse mortgage	RC dwelling, deductible payable from cash	Lapse risk and equity exposure

The Deductible Layer on Top

A deductible comes off after depreciation on an ACV claim, so it stacks on the gap. In Example 1, the $2,500 deductible and the $16,800 depreciation together cost you $19,300.

Moving from a $1,000 to a $2,500 deductible might save around 10% on a $2,640 premium. That's a planning figure, and your carrier's factor may differ. The math:

Savings: about $264/year
Added exposure: $1,500
Break-even: $1,500 ÷ $264 ≈ 5.7 claim-free years

Many wind and hail deductibles are percentages. At 2% on a $320,000 dwelling, that's $6,400 per event, so look for that line on your declarations page. We break down the full range in our $1,000 vs. $2,500 vs. $5,000 deductible review.

Also, if you're thinking about filing a smaller claim, the surcharge and your claim history matter. Our piece on whether to file a $6,000 claim with a $2,500 deductible walks through it.

Your Pre-Renewal Checklist

Set aside 30 minutes this week. Most insurers send notices 30 to 60 days ahead, though it varies by state.

Find the policy form on your declarations page: HO-3, HO-5, or something else.
Check the roof line. Is it replacement cost, ACV, or a payment schedule? What's the age trigger?
Get a fresh rebuild estimate and compare it to your dwelling limit. Check for extended replacement cost.
Total your belongings room by room. Compare to your contents limit and its payout basis.
Look up your flood zone and price a separate flood policy against your rebuild cost.
Check your wind/hail deductible, whether flat or a percentage.
Ask what changed. Request the prior year's declarations page and compare line by line.

Bottom Line

HO-3 vs. HO-5 and replacement cost vs. ACV are separate levers. Which combination is right depends on your roof age, belongings value, rebuild cost, flood zone, and claim history. In the examples above, the roof basis was the biggest gap, the HO-5 upgrade was a close call, and the flood limit was the largest single hole.

If you'd rather not build the spreadsheet yourself, you can run all of this with your own numbers at Veloqua. Review your policy before it auto-renews, because after a claim it's too late to change the form.
