Start With Your Numbers — Not Rightmove
The biggest mistake many upsizers make is falling in love with a property before understanding what’s financially possible.
Before viewing homes, it’s important to understand:
- How much equity you have
- What you could potentially borrow now
- What your monthly payments may look like
- Whether your current mortgage is portable
This gives you a realistic budget and helps avoid disappointment later.
Your Equity Is Key
When upsizing, the equity in your current property plays a huge role.
Equity is the difference between:
- What your home is worth
- What you still owe on your mortgage
If your property has increased in value over time, this can give you a stronger deposit towards your next home.
The more equity you have, the more mortgage options may be available to you.
Your Affordability May Look Different Now
Even if you’ve had a mortgage for years, lenders will still reassess affordability when you move.
They’ll look at things like:
- Household income
- Childcare costs
- Credit commitments
- Monthly spending
- Future affordability
This is especially important for growing families where finances may have changed significantly since your first purchase.
Don’t Forget The Extra Costs
Moving home often costs more than people initially expect.
Alongside your deposit, you may also need to budget for:
- Stamp duty
- Solicitors fees
- Surveys and valuations
- Removal costs
- Emergency furniture purchases
- Decorating and repairs
Having a financial buffer can make the move far less stressful.
Think Beyond The Mortgage
Upsizing often comes with bigger financial responsibilities.
A larger mortgage can also be the perfect time to review:
- Life insurance
- Income protection
- Critical illness cover
Because protecting your family financially becomes even more important as your commitments grow.
Timing Matters
Buying and selling at the same time can feel like a juggling act.
Good planning, clear communication and getting your mortgage organised early can make the process much smoother.
The earlier you understand your position, the more confident you can feel when the right property comes along.
Final Thoughts
Upsizing is about more than square footage, it’s about creating a home that fits your family’s next chapter.
With the right planning and guidance, the process can feel far more manageable.
