Is This Quote Fair?
In short: yes — and then some. This quote has been rated Cheap (Below Average), meaning it comes in significantly under the typical range for comparable properties in Karnup.
At $1,051 annually (or roughly $100 per month), this premium undercuts the suburb's median of $1,610 per year by around $560 — that's a saving of over 34%. It also falls below the 25th percentile for the suburb ($1,211/yr), which means this quote is cheaper than at least 75% of the quotes recorded in the area.
For context, the building excess on this policy is $2,000, which is on the higher end. Insurers often offer lower premiums in exchange for a higher excess, so it's worth considering whether you'd be comfortable covering that amount out of pocket in the event of a claim. That said, if your home is well-maintained and you're unlikely to make frequent small claims, a higher excess in exchange for a lower annual premium can be a smart financial trade-off.

| National average | $2,965/yr |
| National median | $2,716/yr |
(Based on 36 quotes recorded for the Karnup suburb.)
What stands out here is just how far below the national average this quote sits. The national average premium for home building insurance is $2,965 per year — nearly three times the cost of this particular quote. Even against the WA state average of $2,144, this quote represents a saving of more than $1,000 annually.
Karnup itself sits in the City of Rockingham LGA, where the average premium is $1,618 per year — still well above this quote, but noticeably more affordable than the broader WA and national figures. This suggests Rockingham-area properties may benefit from relatively favourable risk profiles compared to other parts of the country.

Property Features That Affect Your Premium
Several characteristics of this particular property work in the homeowner's favour when it comes to insurance pricing.
Double Brick Construction Double brick is widely regarded as one of the most resilient wall construction types available. It offers excellent resistance to fire, wind, and structural stress — all factors that insurers weigh heavily when calculating risk. Compared to timber-framed or clad homes, double brick properties often attract lower premiums, and this home is a clear example of that.
Tiled Roof A tiled roof is another premium-friendly feature. Tiles are durable, fire-resistant, and long-lasting when properly maintained. They're less susceptible to storm damage than some other roofing materials, which reduces the likelihood of a weather-related claim.
Slab Foundation Built on a concrete slab, this home has a stable, low-maintenance foundation type that insurers view favourably. Slab foundations reduce the risk of subsidence and pest-related structural damage — both common concerns in parts of Western Australia.
Relatively New Build (2017) At under 10 years old, this home is considered modern by insurance standards. Newer homes are built to current Australian Standards, meaning they're likely to have up-to-date electrical, plumbing, and structural systems. This reduces the probability of age-related failures that might trigger a claim.
Ducted Climate Control While ducted air conditioning adds to the overall replacement value of the home, it's a standard inclusion for a property of this size and quality. The sum insured of $620,000 appears to account for this, along with the 214 sqm building footprint and standard-quality fittings.
No Pool or Solar Panels The absence of a pool or solar panel system simplifies the risk profile and keeps the insured sum — and therefore the premium — lower. Both features can add meaningful cost to a building insurance policy.

Tips for Homeowners in Karnup
Whether you're reviewing your existing policy or shopping around for the first time, here are a few practical steps worth considering.
1. Check Your Sum Insured Regularly Building costs in Western Australia have risen significantly in recent years due to labour and material shortages. A sum insured of $620,000 for a 214 sqm double brick home seems reasonable, but it's worth recalculating your replacement cost annually — not your property's market value, but what it would actually cost to rebuild from scratch. Underinsurance is one of the most common and costly mistakes homeowners make.
2. Compare Quotes Before Renewing Many insurers automatically renew policies with incremental premium increases each year. Given that this quote came in at less than half the suburb average, it's clear that significant price variation exists in the market. Don't assume your current insurer is offering you the best deal — take the time to compare.
3. Understand What's Not Covered Building-only cover protects the physical structure of your home, but it won't cover your furniture, appliances, or personal belongings. If you have valuable contents, consider whether a combined building and contents policy might offer better overall value.
4. Review Your Excess The $2,000 building excess on this policy is higher than average. If you have the financial buffer to cover that amount comfortably, the trade-off for a lower premium makes sense. If not, it may be worth requesting quotes with a lower excess to find a more balanced option.
