The short version
- You should consider the forever home vs investment property decision years before your first mortgage ends.
- Selling your first home to upgrade leaves you with just one property (your home) that doesn't generate income.
- Keeping your first home mortgage-free and using equity for an investment gives you two properties, one generating income.
- The investment property path is usually financially better, but emotional desires for a better home are valid too.
Why this decision matters sooner than you think
Most people only consider whether to upgrade to a forever home or buy an investment property when they're nearing the end of their first mortgage. Aaron says you should think about it much earlier - as soon as you can afford to make the choice. Starting 10 years earlier puts you in a stronger financial position either way.
This isn't just about rate comparisons or loan terms. It's about your long-term wealth building strategy and whether you prioritise financial growth or lifestyle upgrade in your next property move.
The financial reality of each option
If you sell your first home (now mortgage-free) to buy your forever home, you'll have a big deposit but take on another mortgage. You end up with one nice home, but it's not a true asset - it costs you money to live there and generates no income.
The alternative? Keep your first home (now mortgage-free), use its equity to buy an investment property, and collect rental income. Now you own two properties - one houses you, the other builds wealth. Over decades, this compounding effect creates significant financial advantage.
It's not just about the numbers
Aaron acknowledges that while the investment path is usually financially superior, personal circumstances matter. Some buyers emotionally want - and can afford - that nicer forever home. There's real value in living where you love, even if it's not the optimal wealth-building choice.
The key is making this decision consciously, understanding the trade-offs. Many Aucklanders discover too late that their dream home upgrade locked them into decades more mortgage payments instead of building assets. Get advice early so your next move aligns with your goals.
