Sydney's southern suburbs selling strong: Herron Todd White

Strong demand for homes in the southern Sydney suburbs of Como, Engadine, Gymea and Sans Souci is driving the market for dual occupancy development sites, modern project homes and renovated older homes.

Herron Todd White's October Month in Review noted large premiums are being paid for the potential dual occupancy sites with building and renovating costs increasing due in part to a tight employment market for builders.

"An example of a strong result within the year in Como is a modern 5-bedroom project home  recently selling at auction for an astonishing $1.8 million," the report said.

"This home was previously sold in March 2014 for $1.355 million, so this was a tidy profit.

"Local agents attribute the increase to the mere convenience of move in and enjoy with absolutely no work required."
