A house can cost £350,000 without a move costing £350,000. That sounds obvious until you watch how people budget for a purchase. The deposit gets most of the attention because it is the largest pile of cash they need to assemble. The mortgage gets the second-largest share because it determines whether the monthly payment feels survivable. Everything else is often put into a vague mental category called “fees”, as though the solicitor, surveyor, tax authority, lender and removal company have all agreed to share one modest envelope.
They have not. The uncomfortable part of buying a home is that several costs become real at almost the same time. Stamp Duty can run into thousands. Legal work and searches need paying for. A proper survey can reveal a problem that changes the negotiation. The mortgage itself may have a product fee. Then there is registration, removals, insurance and the small collection of costs that appear after completion when the new house turns out to need curtains, a locksmith and exactly one more trip to the hardware shop than you thought possible.
The useful number is therefore not simply the purchase price or the deposit. It is the amount of cash you need to complete the move without arriving at the new front door financially exhausted.
Start with a £350,000 purchase
Consider an illustrative buyer purchasing a £350,000 freehold home in England. The example assumes this is their main residence, the purchase does not attract additional-property rates, and they are not subject to the non-UK resident surcharge. It also assumes a transfer of the whole of an existing registered title, which matters for the registration fee later.
Under the residential Stamp Duty Land Tax rates applying from 1 April 2025, the standard rates are 0% on the first £125,000, 2% on the next £125,000 and 5% on the portion from £250,001 to £925,000. For this purchase, the calculation is £125,000 at 0%, £125,000 at 2% and £100,000 at 5%: £0 + £2,500 + £5,000 = £7,500.
That £7,500 is separate from the deposit. If you had saved a 10% deposit of £35,000 and mentally concluded that £35,000 was the cash needed to buy the property, you would already be £7,500 short before paying a solicitor, ordering a survey or moving a single box.
Qualifying first-time buyers purchasing for £500,000 or less receive relief: no SDLT on the first £300,000 and 5% on the balance up to £500,000. All joint buyers must qualify. On the same £350,000 home, that produces £2,500 rather than £7,500. The same house can therefore create a £5,000 difference in tax simply because the buyer’s circumstances are different.
The worked moving budget
Let us build an illustrative budget for the standard-rate buyer. The variable professional fees below are assumptions, not market quotes. Figures include VAT where applicable; searches and registration are shown separately from the legal fee to avoid counting them twice. The mortgage product fee is paid upfront in this example.
| Cash needed | Illustrative amount |
|---|---|
| 10% deposit | £35,000 |
| SDLT | £7,500 |
| Conveyancing legal fee | £1,500 |
| Searches | £350 |
| RICS survey | £600 |
| Mortgage product fee | £999 |
| Land Registry fee | £150 |
| Removals | £800 |
| Buildings insurance / immediate setup allowance | £250 |
| Total cash requirement | £47,149 |
The striking number is the difference between the deposit and the total. The buyer thought in terms of £35,000. This illustrative transaction requires another £12,149 around it. The deposit contributes towards ownership of the home; it is not a fee consumed by the move. This is a cash-planning total, not a claim that £47,149 disappears into transaction charges.
If the same buyer qualified for first-time buyer relief, replacing £7,500 of SDLT with £2,500 would reduce the total to £42,149. Still materially more than the deposit. Neither total includes a substantial emergency reserve, major repairs or the costs of selling another property.
This is why “I have my deposit” and “I am financially ready to move” are not the same statement. Your actual solicitor, lender, surveyor and removal company may charge more or less, and the £250 setup allowance is deliberately modest. It is not a substitute for money held back for surprises.
Stamp Duty is often the biggest non-deposit cost
For many buyers in England and Northern Ireland, Stamp Duty is the line that moves the budget most dramatically. The tax is progressive: different rates apply to different portions of the price, rather than one rate to the whole purchase. HMRC’s higher-rate guidance explains that additional-property purchases usually face an extra five percentage points, while certain non-UK resident purchases face a separate surcharge.
Moving from one price point to another therefore does not simply increase the mortgage. A buyer stretching from £325,000 to £375,000 may focus on finding the extra £50,000, but under the standard assumptions here the SDLT also increases by £2,500. Both prices remain within the same registration-fee band; other transaction costs depend on the particular property and work involved.
Wales and Scotland use different property transaction taxes. GOV.UK’s property-tax guidance distinguishes SDLT in England and Northern Ireland from Land Transaction Tax in Wales and Land and Buildings Transaction Tax in Scotland. Do not copy an English calculation across the UK. Calculate the tax for the actual location, price and buyer circumstances before deciding how much cash is available for the deposit.
The solicitor’s bill is more than “the solicitor”
Conveyancing is another cost people often compress into one estimate. The legal professional handles the transfer of ownership, but the bill can contain professional fees and disbursements: amounts paid to third parties as part of the transaction.
Once an offer is accepted, the conveyancer arranges the relevant searches. The government’s home-buying guide explains local authority searches and the additional investigations a legal professional may recommend. These are not decorative paperwork. They can reveal restrictions or risks affecting the property and the decision to proceed.
Leasehold purchases can create additional work because the conveyancer may need to review the lease, service charges and management information. Our example is freehold, so a leasehold buyer should not assume the same legal allowance covers their circumstances.
A quote that looks cheap needs to be compared on the same basis as another quote. Does it include VAT, searches, bank-transfer charges, acting for the mortgage lender, leasehold supplements and registration? Ask which items are estimates and which are fixed. The useful question is not simply which solicitor is cheapest, but what the whole legal side of this particular purchase will cost.
The Land Registry fee is small enough to forget
Ownership needs to be registered following the purchase. HM Land Registry’s Scale 1 fees show a £150 charge for a transfer valued between £200,001 and £500,000 affecting the whole of a registered title, submitted electronically through the portal or Business Gateway. That fits our £350,000 example.
It is not the largest number in the move, but this is exactly how costs accumulate: £150 here, a few hundred pounds there, and suddenly the vague “fees” allowance has disappeared. Other application types or submission methods can cost more, including transfers of part of a title and first registrations.
The point is not to memorise £150. Ask your conveyancer which fee applies and whether it is already included in the overall quote. It belongs in the budget because it is part of completing the purchase, not because it is interesting.
A mortgage valuation is not your survey
Your lender normally values the property before agreeing to lend. That valuation is primarily for the lender: it checks whether the home is adequate security for the mortgage. It is not the same as commissioning an independent survey of its condition. Which?’s valuation guide explains that the assessment can be very limited and may not involve anyone entering the property.
RICS describes three Home Survey levels. Level 1 gives a basic overview for conventional homes in good condition. Level 2 provides more detail for conventional properties in reasonable condition. Level 3 is the most comprehensive and is suited to older, unusual, altered or run-down buildings, or where major work is planned. Discuss the appropriate service with the surveyor rather than selecting solely on price.
RICS says costs vary from a few hundred pounds at the simpler end to more than £1,000 for some detailed services. The temptation to save £500 or £700 is understandable when you have already transferred thousands to everyone else. But that saving can look different if the property later needs a £15,000 roof repair that a suitable survey might have highlighted before exchange.
A survey cannot guarantee that every problem will be found. It is still one of the transaction costs that can provide information capable of changing the price or your decision to proceed.
The survey can change the negotiation
Suppose the surveyor identifies urgent work at our £350,000 property. Perhaps the roof needs substantial repair, damp requires investigation and the electrical installation needs attention. You now have information you did not have when making the offer.
Depending on the circumstances, you might proceed at the original price, renegotiate, ask the seller to address particular issues or walk away before exchange. If documented work leads to a £7,500 reduction, a £600 survey has helped inform a much larger financial decision. The survey still costs £600, and the discount is not pure profit: you may have to spend it on the repairs that prompted the negotiation.
The seller does not have to agree, and not every defect justifies a reduction. The point is that due diligence can influence the economics of the purchase. Skipping it simply to protect the moving-cost budget can be false economy. Get repair estimates where appropriate, so a reassuring discount does not distract you from a larger bill waiting after completion.
Mortgage fees deserve more attention
The mortgage itself can carry upfront or financed costs. Some deals have no product fee; others charge hundreds or more than £1,000. Which?’s research on mortgage fees illustrates why the lowest headline interest rate does not necessarily produce the lowest cost over a deal period.
A fee can often be paid upfront or added to the borrowing. Adding it solves an immediate cash-flow problem, but you may then pay mortgage interest on it. If our £999 fee is financed instead, the illustrative upfront cash total falls from £47,149 to £46,150, while the loan increases by £999. You have not made the fee disappear. You have borrowed it.
The correct comparison considers payments, fees and the mortgage balance remaining over the same period, rather than treating deferred borrowing as a saving. Changing when you pay for something is not the same as removing its cost. Check any broker or valuation fee separately too; neither is included in our worked allowance.
Once the move is complete, the decision about overpaying a mortgage or keeping accessible savings raises a related question: a lower debt balance is useful, but so is having cash available when the house needs attention.
Moving your possessions is a real cost too
Eventually, the legal work completes and the problem becomes more physical: everything you own is in the wrong building. Removal costs depend on the amount being moved, distance, access and whether packing is included.
HomeOwners Alliance’s removals guide reports £792 for a three-bedroom house, using August 2026 data from Reallymoving. Its headline comparison is for a move within 25km, and the table includes VAT. This is a particular benchmark, not a promise that every three-bedroom move costs that amount.
Our £800 allowance is therefore an illustration. A local move from a small flat using a hired van could cost much less. A large long-distance move with packing could cost substantially more. Ask about access, waiting time, insurance and any extra services when comparing quotes.
What matters is obtaining real figures before completion rather than assigning “a few hundred pounds” because that number feels convenient. The cheapest quote is only comparable if it covers the work you actually need done.
Buying and selling adds another layer
Our example covers the purchase side only. If you are also selling, the economics expand again: estate-agent fees, sale-side conveyancing, mortgage exit or early repayment charges, and potentially costs created by the chain. A seller generally needs a valid Energy Performance Certificate unless exempt, as GOV.UK’s EPC guidance explains.
Estate-agent fees can be significant because they may be linked to the sale price. Some costs are settled from sale proceeds on completion, while others need paying earlier. A household can therefore have substantial equity and still run short of accessible cash during the move.
Distinguish costs paid upfront, amounts needed at exchange or completion, deductions from sale proceeds, costs added to borrowing and bills arriving after moving. If your deposit comes from a sale, it need not all be new savings, but the timing still needs to work. Ask the conveyancer to explain the funds required and when they must arrive.
The total matters, and so does the timing. A budget that is correct overall can still fail if money becomes available a week after a bill is due.
The chain can make sunk costs painfully real
In England and Wales, an accepted offer is generally not legally binding until contracts are exchanged. The government’s buying overview makes that distinction clear. A purchase can therefore collapse after you have already paid for searches, mortgage work or a survey.
If the seller withdraws, the survey reveals an unacceptable problem or the chain collapses, some payments may not come back. Which?’s explanation of gazumping highlights the risk of losing money spent on conveyancing, surveys and mortgage applications when another offer is accepted.
That does not mean you should avoid due diligence. It means some of the budget is exposed before you are guaranteed to own the property. Check refund terms rather than assuming that every payment is recoverable if the move falls through.
A buyer using every available pound for the best-case scenario has little capacity to absorb a failed purchase and try again. The possibility is uncomfortable, but ignoring it does not make the eventual cash shortage easier to manage.
Completion day is not the end of spending
Then you get the keys, and every carefully constructed spreadsheet encounters the house itself. Perhaps the previous owner took the curtains. The locks need changing. The broadband installation is three weeks away. The fridge does not fit. The lawn appears to have been waiting specifically for you to buy a mower.
None of these is individually part of the purchase price. Collectively, they can make the first month expensive. Ongoing costs also need a fresh budget: insurance, Council Tax, utilities, maintenance and any service charges may differ from your previous home. A mortgage payment is only one line in that calculation.
Insurance timing deserves attention before moving day too. The government’s home-buying guide advises arranging buildings insurance from exchange; confirm the requirements for your transaction with your conveyancer and lender. Do not assume everything starts when the keys arrive.
The sensible moving budget therefore needs a post-completion buffer. Buying with £42 left in the current account may technically count as completion, but it is not an especially comfortable way to begin homeownership. Our guide to building a budget without counting spending twice can help separate the one-off move from the monthly life that follows it.
A cash target, not just a deposit target
Return to the £350,000 purchase. A buyer might start by saying, “We need a 10% deposit, so our target is £35,000.” A better conversation is, “We need £35,000 for the deposit. What else needs cash before and around completion?”
The answer in our example is £7,500 tax plus £4,649 for the other listed fees and allowances, taking the total to £47,149. It still excludes major repairs, furniture, sale costs and a substantial reserve. The point is not that every buyer needs precisely this amount. The point is that a deposit-only target systematically understates what needs funding.
First-time buyer relief helps enormously: the qualifying buyer’s £5,000 tax reduction takes the total to £42,149. But the solicitor still needs paying, registration still happens and the van does not become free because the tax bill is lower. Reaching the deposit goal is a real achievement. It should trigger a second check of transaction costs and reserves, rather than an assumption that saving is finished.
Spend deliberately, then keep something back
There are places where minimising one fee can increase the overall risk. The cheapest conveyancer may be excellent, but price alone tells you little about communication during a time-sensitive chain. Skipping a survey saves a fee while potentially losing useful information. A low-rate mortgage may cost more over your chosen period once charges are included.
Hiring the cheapest removal option may be perfectly sensible. It may also become less attractive when your sofa is halfway down a staircase and everyone involved has stopped speaking to one another. The objective is to spend deliberately on work that reduces risk, then avoid charges that add little value.
Before viewing seriously, organise four pots: the deposit, transaction costs, a post-completion buffer and an emergency reserve that survives the move. For money waiting to be used, compare cash ISAs and ordinary savings accounts on access as well as interest. A slightly better return is unhelpful if the cash cannot be released when your conveyancer needs it.
If buying the home means emptying every account and putting moving costs onto a credit card, it may fit the lender’s affordability model while still being too tight for the household. The lender decides whether it is prepared to lend. You decide whether you can afford to live afterwards.
The house price is the headline
Property listings focus on the purchase price, and mortgage calculators focus on the deposit and monthly payment. But a purchase involves tax, legal work, due diligence, finance, registration and logistics before ordinary life in the new home begins.
The most useful question is therefore not simply whether you can afford the deposit. It is how much cash will remain after completing the whole move. A £350,000 house may be the right purchase, and a £35,000 deposit may be enough for the mortgage. But if the move needs another £10,000 or £12,000 around it, that money needs to exist somewhere.
It is much better to discover that while building the savings target than three days before completion.
