New research by Nine News has found that buying a house may not always be the best investment strategy for your family's future.
"You want to believe that house prices will always go up," Nine finance editor Ross Greenwood said.
"But when interest rates rise, house prices will often go flat and sometimes go backward."
The research has shown that over five, six, seven and eight years, house prices around some parts of Sydney have been flat and in some cases have not appreciated enough to cover mortgage interest costs .
Greenwood said families face the dilemma over whether to put the money in the bank and rent a home or buy a property instead.
