When it comes to buying your dream home, one of the first decisions you’ll need to make is whether to build a new one or buy an existing home. There are pros and cons to both options, and the right answer will depend on a few factors such as:
- What’s your budget?
- Are you set on a specific location?
- Do you have a timeline for moving into your new home?
Buying an existing home
Benefits
- Less surprises as you know in advance what you'll be getting with property inspections and building & pest inspections
- Established community & infrastructure
- Typically, faster than building, once you have purchased the home
Cons
- Depending on the age of the house, there may be outdated features and designs
- Potential need to renovate if it doesn’t suit all your needs
- Higher maintenance costs could be involved
- Higher government fees associated such as stamp duty
Building a new home
Benefits
- Greater control over the design & features
- Potentially lower ongoing maintenance and energy costs
- Ability to access government grants and stamp duty concessions
Cons
- May experience project delays
- Can be time consuming
- May have unexpected costs which could blow out your budget
- Risk of poor construction work, depending on your builder
