Why people rarely sell in these suburbs

According to the report, several factors can explain why homes in the suburbs above almost never sell.

One factor is affordability - of the 10 suburbs in the list, three have a median price above $1m, with houses in Malabar coming in the most expensive at $2.68m.

"The suburbs aren’t particularly expensive which shows that you don’t need to live in the most expensive suburbs to enjoy living there," the report said.

Another factor is the high proportion of older residents in these suburbs.

The report said long hold periods often reflect the general sense of lifestyle of a suburb.

"Many of these areas contain older people that would have bought when the suburb was just being developed. Over a long time period they have become attached to the suburb and have decided not to move.”

Furthermore, many suburbs with long hold periods have large homes on decent-sized blocks.

"It doesn’t include very large homes which could explain why older people are able to stay in the suburb," the report said.

"Many of the suburbs on the list are pretty nice places to live; they include established retail precincts and parkland and most of them have decent public transport."
