Turn home equity into a real move-home deposit plan
Use the sell-to-buy calculator while you read to see how sale proceeds, fees, and buying costs affect the equity really available for your next move.
Many movers ask, "How much equity do I need to move house?" The honest answer is that there is no single number that fits everyone. What matters is not just how much equity you have on paper. What matters is how much usable equity is left after you clear the mortgage, pay the selling costs, and cover the buying costs tied to the next home.
This is where a lot of people get caught out. They know their property has gone up in value, but they have not yet translated that value into a working deposit for the next purchase. That is the number that really shapes whether the move feels comfortable, tight, or unrealistic.
This guide walks through the process in plain English so you can turn "home equity" into a more practical move-home plan.
Important: this is general information only. Mortgage approval, sale timelines, and legal or tax costs depend on your own circumstances. Use this guide to plan, then confirm the details with your lender, broker, solicitor, and any adviser you rely on.
Quick answer: what equity really means for a mover
For a home mover, the number that matters is usually:
sale price - selling costs - mortgage left to clear + savings - buying costs = working deposit for the next home
That is why a property owner can have "good equity" in a general sense but still feel tight when moving. The sale may look strong until agent fees, VAT, legal costs, repairs, stamp duty, and the next mortgage all come into view together.

Step 1: Start with a realistic sale price, not the highest valuation
Your starting point is the realistic sale range for your current home.
- Check local sold evidence, not just asking prices.
- Compare estate agents, but do not assume the highest valuation is the most likely outcome.
- Be honest about the difference between a sale that is possible and a sale that is probable.
If your next move only works at the very top of the valuation range, your plan is probably tighter than it looks.

Step 2: Subtract the mortgage still owed
This sounds obvious, but it is amazing how often people mentally compare the full sale price of the current home with the price of the next home. That is not the real comparison.
- If your home sells for EUR 550,000 but you still owe EUR 280,000 on the mortgage, a large part of the sale proceeds is already spoken for.
- Your usable equity only starts to appear after the mortgage redemption figure is taken into account.
This is why some movers with apparently valuable homes still feel stretched. The property value may be strong, but the mortgage balance still absorbs a big chunk of the move.
Step 3: Subtract the cost of selling
Before you think about the next home deposit, take off the cost of getting out of the current one.
- Estate agent commission.
- VAT on that commission.
- Marketing costs.
- Seller solicitor fees.
- Repairs, BER work, staging, or light prep spend.
- Any mortgage break fee or other exit cost.
Those costs do not just reduce profit. They reduce the deposit available for the next move. That is why even a few thousand euro here and there matters more than many movers expect.
Useful tools and guides:
Step 4: Add any savings that are already available for the move
Equity is not always the whole story. Some movers already have cash savings, bonus income, or other funds set aside for the move.
- Do not mix "savings I could maybe use" with "cash I am definitely willing to use."
- Separate committed move funds from emergency savings if you do not want to leave yourself exposed after completion.
- Treat any family support or other funding carefully and only count it once it is genuinely available.
The more of the move you can support from confirmed cash rather than optimism, the safer the plan usually becomes.
Step 5: Subtract the cost of buying the next home
This is the part that changes "equity" into a real working deposit.
- Stamp duty.
- Buyer solicitor costs.
- Survey and valuation fees.
- Moving costs and immediate setup spend after completion.
If a mover forgets these costs, they can easily overestimate their usable deposit by many thousands of euro. That can push a move from comfortable into tight without them realising it until late in the process.
Step 6: Decide what level of equity actually feels comfortable
There is no universal "you need EUR X equity to move" rule. A more useful question is:
After all costs, does the deposit left still support the next mortgage and leave a sensible buffer?
In practice, stronger equity usually gives you:
- More choice on the next purchase.
- Lower mortgage pressure.
- More resilience if timelines shift or costs creep higher.
- Less risk of feeling forced into a compromise later.
Tighter equity usually means:
- The move only works at the top end of the sale range.
- The next mortgage feels larger than you are comfortable with.
- There is very little room for buying costs, repairs, or timeline disruption.
What level of equity often signals a tighter move?
A move often starts to feel tight when:
- The deposit left after buying costs is only just enough to clear the minimum lender-style deposit expectation.
- The next mortgage still feels big relative to income and monthly outgoings.
- You would need a best-case sale outcome to make the numbers work comfortably.
- There is very little cash left after completion for furniture, minor works, or normal life shocks.
Plain-English rule: good equity is not just "enough to proceed." It is enough to proceed without feeling one surprise away from panic.
Step 7: Use equity planning to improve your move strategy
Once you know roughly what equity is really available, you can make better decisions.
- You can decide whether the next-home target price is still sensible.
- You can see whether selling first or buying first feels safer.
- You can tell whether a stronger sale outcome would materially improve the move.
- You can decide whether to wait, save more, or adjust expectations before pushing ahead.
That is one reason this calculation matters so much. It is not just a spreadsheet exercise. It changes the strategy of the whole move.
How movers can improve their usable equity position
- Reduce avoidable selling costs where sensible.
- Pressure-test the estate agent and sale strategy rather than picking only on fee.
- Reconsider the target price of the next purchase if the current plan feels too stretched.
- Add more savings or delay the move if the buffer is too thin.
- Be realistic about whether a smaller, cleaner move now is better than an over-stretched move later.
FAQ
Is home equity the same as deposit for the next house?
No. Home equity is the broad value left after subtracting the mortgage from the current home. Your usable deposit for the next home is usually lower because selling costs and buying costs still have to come out.
Can I move house with relatively low equity?
Possibly, but the move is more likely to feel tight. It depends on your next purchase price, your income, your savings, and how much flexibility you still have after costs are included.
What is the biggest mistake people make when estimating equity for a move?
One of the biggest mistakes is forgetting how much the selling and buying costs together reduce the cash actually available for the next deposit.
Does stronger equity change whether I should sell first or buy first?
Yes, it can. Movers with stronger equity and more buffer may have more flexibility. Movers with tighter equity usually benefit from more certainty and more conservative sequencing.
