Common questions about living on and buying property on Summit Ave, Dee Why NSW 2099 — lifestyle, transport, and the local housing market.

Is Summit Ave an expensive or affordable street relative to Dee Why?

House prices on Summit Ave are not currently priced relative to the Dee Why suburb house median. This indicates there are insufficient recent house sales on the street to calculate a reliable premium or discount compared to the broader Dee Why market. Buyers should review recent sales of similar detached homes in the surrounding Dee Why area to gauge current pricing benchmarks.

What are the risk and overlay factors on Summit Ave?

There are no bushfire, heritage, or high-voltage overlays affecting properties on Summit Ave. Flood risk is also minimal, with no properties falling within a flood overlay or recommended for a flood check. Sixteen homes have been reviewed and classified under other flood categories, meaning no flood risk has been identified or the properties are not mapped for flood.

Are properties on Summit Ave mostly on high, level or low ground?

The street features a balanced elevation profile with 8 homes on level ground and 8 on low-lying land. There are no properties recorded on the high side. This even split means site characteristics vary significantly between individual homes. Buyers should assess the specific elevation and drainage of the property they are considering rather than relying on the street average.

What type of road is Summit Ave?
