This ratio indicates that the street sits just under the average price point for houses in the area, offering a modest discount relative to the suburb-wide median without implying significant undervaluation or premium pricing.

Additionally, 102 properties are classified under other flood categories, meaning no flood risk has been identified or they have not been mapped for flood.

Are properties on Cook St mostly on high, level or low ground?

The street has a mixed elevation profile with 43 properties on level ground, 42 on the high side, and only 2 on the low side. While the distribution is nearly even between level and high ground, buyers should assess the specific site characteristics of their chosen property rather than relying on the street average, as elevation can influence drainage and site access on a case-by-case basis.

What type of road is Cook St?

Cook St is classified as a collector road with a 50 km/h speed limit, and 97.5% of the residential properties front this section. Collector roads generally connect local streets with larger arterial roads, serving both local residents and through traffic. Buyers should consider that this classification may result in slightly higher traffic volumes compared to a local residential street, though the 50 km/h limit helps manage vehicle speeds.

Is Cook St mostly houses or apartments?

Cook St has 158 residential properties, with 64.6% being houses and 0% being apartments. This means the street is predominantly composed of houses, duplexes, and terraces, with no apartment stock recorded.

What are the major apartment developments on Cook St?

No major apartment developments are recorded on Cook St. The street's residential character is defined by its house-type stock rather than high-density apartment complexes. Buyers seeking large-scale apartment living or specific development amenities will not find these features on this street, as the housing profile consists exclusively of houses and associated residential types.

Is Cook St a good street to buy property on?

Cook St may suit buyers seeking a house on a collector road with a 50 km/h speed limit, particularly those comfortable with a 2.24% discount to the suburb median. It is also appropriate for buyers who do not mind bushfire zoning but prefer the flexibility of no heritage or flood overlays. The street is not suitable for apartment buyers, as the stock is exclusively houses, and those prioritising quiet local streets may find the collector road classification less ideal.
