Separate property price from cash needed
The purchase price may be funded by a combination of your own money and a mortgage. Property tax is a separate acquisition cost. The “price plus tax” figure in our calculator combines those two amounts; it is not a prediction of the cash you must transfer to your solicitor.
A useful budget lists each source of funding and each cost separately. Start with your lender’s offer and the conveyancer’s completion statement, then add costs paid outside that statement.
Build a budget from your own quotes
Include your purchase deposit, tax, legal fees and disbursements, survey or valuation charges, lender fees paid upfront, and moving costs. Some fees may be added to a loan or already included in another quote. Avoid counting them twice.
The worksheet adds your figures locally in your browser. It does not estimate the market cost of legal work or mortgage products, and it does not store your entries. Use written quotes rather than generic fee assumptions.
Allow for changes before completion
If you increase your offer, recalculate the property tax. If selling an existing home is delayed, check whether additional-property tax becomes payable upfront. A first-time buyer near the SDLT relief cap should compare tax on both the old and new offer.
Keep any possible tax refund separate from the money needed at completion. A later repayment may depend on a sale, an eligibility check and a claim, so it should not be treated as cash already available.
Check the final figures with the people handling the purchase
Ask your conveyancer which amounts are included in the completion statement, when cleared funds are required, and who will file the property tax return. Confirm lender charges against the mortgage documents.
This worksheet is for organising figures you provide. It does not assess mortgage affordability, recommend borrowing or cover ongoing household costs. After the purchase, you will need a separate budget for loan payments, insurance, utilities, maintenance and any service charges.
