Wentworthville (postcode 2145) sits approximately 27 kilometres west of the Sydney CBD in Greater Western Sydney, straddling the boundary between the City of Parramatta and Cumberland Council. Its SEIFA IRSAD score of 1033 places it in the 8th national decile, meaningfully above the national mean of 1000. Within New South Wales, that score lands at the 67th state percentile, confirming a relative socioeconomic advantage over the majority of NSW suburbs. For investors using PropertyRanker, this reading feeds directly into three of the model's twelve scoring criteria: economic_strength, hazard_risk, and entry_point_risk.
ABS 2021 IRSAD release. Score 1033 (national mean = 1000).
A decile 8 SEIFA reading signals that the resident population, on average, faces fewer markers of disadvantage than roughly 70 percent of Australian suburbs. In practical terms, this tends to correlate with more stable rental demand, lower arrears risk, and a tenant pool with broader income diversity. Those are useful macro conditions, but they describe the postcode frame, not any individual property inside it. Wentworthville contains a genuine mix of detached houses, older villa complexes, and newer apartment buildings, and the investment case can differ sharply between those asset classes even within the same street. The suburb's position on the Western rail line, with direct access to Parramatta and the Sydney CBD, supports commuter demand. Proximity to the Westmead hospital and health precinct adds an employment anchor that tends to underpin rental occupancy. Infrastructure investment in the broader Parramatta corridor, including planned metro extensions, is a structural tailwind that investors in this postcode frame are watching. Against that, the suburb's density is rising, which can compress yields on units if new supply outpaces absorption. The SEIFA score does not capture supply pipeline, strata levies, flood overlays along the creek corridors, or the condition of individual buildings. A Capital Growth strategy (targeting around 3.5 percent gross yield) may suit well-located houses here, while a Balanced strategy (around 5 percent) could apply to quality units, but neither conclusion holds without checking the specific listing against current vacancy and comparable sales data.
Wentworthville (NSW 2145) recorded a median house sale price of $1,500,000 over the 12 months to February 2026, representing annual growth of approximately 4.9-5.2% according to CoreLogic data published by yourinvestmentpropertymag.com.au and propertyvalue.com.au (Cotality). There were 102-103 house sales over the same period, with average days on market of 26-41 days depending on the source, and vendor discounting of -9.0% per propertyvalue.com.au. The NSW Valuer General recorded a 2025 median of $1,471,000, up 3% on the prior year, indicating steady but moderate price appreciation across the suburb.
With days on market in the 26-41 day range and vendor discounting at -9.0% but no published directional trend for either DOM or vacancy, signals are mixed and the market is assessed as steady.

PropertyRanker scores any Australian property against 12 criteria across three pillars: Growth, Cashflow, and Risk. SEIFA is a primary signal for economic strength and a supporting one for entry-price risk. It also informs the crime side of hazard risk, though physical overlays like flood, bushfire and coastal exposure, and recorded crime data where available, take priority there. The decile of 8 shown above gives a listing in Wentworthville a stronger starting line on economic strength than the national median postcode, and a softer one on entry-price risk, since more advantaged postcodes usually carry higher entry prices.
On top of that, PropertyRanker chooses one of four strategies (Balanced, Growth, Yield, Regional) and applies a per-strategy yield anchor. The anchors are 3.5% for Growth, 5% for Balanced, 6% for Yield, and 7% for Regional. A postcode at this level of relative advantage tends to suit the Growth (3.5% anchor) and Balanced (5% anchor) strategies more readily than Yield (6%) or Regional (7%), because a higher entry price compresses the gross yield a listing can reach without a specific value-add.
Read the scoring guide for the full criteria list and how the verdict thresholds work.
Before drawing any investment conclusion from the SEIFA reading, an investor should confirm several things at the listing level. First, check whether the property sits within the City of Parramatta or Cumberland Council boundary, as planning controls, rates, and overlay rules differ between the two. Second, review flood and stormwater overlay status, particularly for properties near the creek corridors that run through the suburb. Third, for any strata title, obtain the most recent body corporate financials and check the sinking fund balance, because older villa and apartment stock in this postcode can carry deferred maintenance. Fourth, compare the asking price against recent comparable sales in the same street or building rather than relying on suburb-wide medians. Fifth, check the current SQM vacancy rate for the postcode, because rising apartment supply in the Parramatta corridor can shift vacancy quickly. Score the specific listing in PropertyRanker for a verdict that accounts for what this postcode-level SEIFA reading cannot see: live vacancy data, body corporate health, flood and overlay status, and pricing against recent comparable sales.
The SEIFA IRSAD score of 1033 (national decile 8, NSW 67th percentile) indicates an above-average socioeconomic profile, which is a positive macro signal for rental demand stability and economic resilience. However, SEIFA is one of twelve signals in PropertyRanker's model and cannot assess the specific asset, its condition, or current vacancy. Whether a particular listing in Wentworthville stacks up depends on the property type, price paid, and live market conditions, so scoring the individual listing is the necessary next step.
The suburb's proximity to Parramatta, the Western rail line, and the Westmead health precinct suggests that demand drivers are more consistent with a Capital Growth or Balanced strategy than a High Yield or Regional one. PropertyRanker's Capital Growth strategy anchors around a 3.5 percent gross yield, while the Balanced strategy targets around 5 percent. Houses in the suburb may lean toward the Capital Growth frame, while units could sit closer to Balanced, but neither conclusion is reliable without checking the specific listing's yield against current asking rents and comparable sales.
The postcode sits across two LGA boundaries (City of Parramatta and Cumberland Council), so planning controls and overlay rules are not uniform across the suburb. Rising apartment supply in the broader Parramatta corridor is a supply-side risk that can compress unit yields and push vacancy higher. Properties near the suburb's creek corridors may carry flood overlay conditions that affect insurability and resale. Older strata stock can also carry deferred maintenance costs that are not visible in the SEIFA reading or suburb-level price data.
PropertyRanker applies twelve scoring criteria to each listing. The SEIFA IRSAD reading (score 1033, decile 8 nationally) feeds into three of those criteria at the macro level: economic_strength, hazard_risk, and entry_point_risk. The remaining nine criteria draw on listing-level inputs including current SQM vacancy for the postcode, body corporate financials for strata properties, flood and planning overlay status, and the listing price relative to recent comparable sales. The SEIFA component is fixed at the postcode level; the other criteria vary by individual property.
All three suburbs share the 2145 postcode and the Western rail line, so they operate within a similar macro frame. Westmead carries a stronger employment anchor through the hospital and health precinct, which can support more consistent rental demand but may also command a price premium. Pendle Hill tends to offer a quieter residential character further from the Parramatta commercial core. Wentworthville sits between the two in terms of amenity density and commuter convenience. Investors should score specific listings in each suburb separately in PropertyRanker, because asset type, price, and vacancy can diverge significantly even within the same postcode.
