AA Financial Planning managing director Kane Jiang says first home buyers often rush into buying property to keep up with those in their social circle when they should take their time instead.
"Quite a lot of first home buyers rush into making decisions and it could be that they follow the herd, some friends ... or some family members," he said.
Jiang said sometimes first home buyers make price the leading criteria, which can have its drawbacks later down the track.
"Things are cheap sometimes for a reason," he said.
"It could be that the area might not have a lot of future growth or future potential or it could be an area that is not an ideal place to eventually raise a family."
Jiang advises some first home buyers to consider having a trusted family member or friend bid for them at auction so they stay within budget.
He said it was important to research a suburb's property sales history using data from an independent source rather than relying on information from real estate agents.
ASIC's MoneySmart senior executive leader Laura Higgins said it's important for first home buyers to research what type of mortgage best suits their needs.
For example, when considering a mortgage linked to an offset account, first home buyers should research whether that feature works for people with similar circumstances.
"Understand how a product is put together and understand where the real benefit is for you and if it's actually a cost saving for you over time," she said.
Mr Jiang said it was prudent to secure pre-approval for a loan before making an offer, which makes you a more attractive option for a seller needing to move quickly.
The official cash rate in New Zealand is at a record low 1.75 per cent, and it's likely to stay there until 2019.
Jiang said some first home buyers might consider a fixed rate home loan for the next few years to provide more certainty around loan repayments, while others may make extra repayments to establish a buffer in the event of rate rises.
Higgins said it was important to revisit your mortgage regularly to ensure it still meets your needs.
