A useful deposit plan answers two questions: how much cash must be ready for the purchase, and how much can you put aside without borrowing it back for everyday bills? Keep the deposit, buying costs and emergency reserve on separate lines.
Give each part of the target its own line
For an ordinary owner-occupier mortgage within the Central Bank limits, first-time and subsequent buyers generally need at least a 10% deposit. That is a regulatory baseline, not a promise of mortgage approval. A lower loan offer can leave you needing a larger cash contribution.
| Budget line | What to record |
|---|---|
| Purchase contribution | Price less the mortgage amount actually available to you |
| Transaction costs | Stamp duty, solicitor quote, registration, valuation and survey |
| Moving and immediate work | Moving, essential repairs and basic setup |
| Emergency reserve | Money you intend to keep after completion |
Turn the gap into a monthly target
Use this planning formula: (cash target − usable savings) ÷ months available. Do not count money reserved for emergencies twice. Treat unconfirmed support, a possible bonus or an expected gift separately until its availability and conditions are clear.
For illustration, a cash target of €45,000 with €21,000 already available leaves €24,000. Over 24 months that is €1,000 a month. These are invented budgeting figures, not an estimate of average Irish buying costs. If only €700 is sustainable, the same gap takes about 35 months, ignoring interest and changes in costs.
Test the plan against an ordinary month
- Start from take-home pay and actual bills, rather than your best month.
- Include annual expenses by setting aside a monthly amount.
- Make the savings transfer after payday and check whether it stays saved.
- Record the source of gifts or other contributions and ask the lender what evidence it needs.
A missed target is information. Adjust the timeline or purchase budget instead of using consumer borrowing to make the savings balance look stronger.
Keep the purchase money available
Compare access conditions and withdrawal restrictions before choosing where to hold the money. Avoid assuming that an investment will be worth a particular amount on your intended buying date. Review the plan when your income, household costs or likely purchase price changes.
Review the target after a setback
If an essential expense reduces your savings, record the new balance and recalculate the gap. Keep the change visible in the timeline instead of assuming you will recover it through a future bonus or investment gain.
What if a repair bill interrupts the plan
| Keep separate | What to establish |
|---|---|
| Starting gap | With a fictional EUR 24,000 gap, saving EUR 800 monthly takes 30 months before interest. |
| Setback | A EUR 2,400 essential bill increases that gap to EUR 26,400, or 33 months at the same monthly saving. |
| Decision | Change the date or affordable purchase target explicitly rather than silently counting an uncertain future bonus. |
