On a £250,000 property purchased with a 10% deposit, the true 10-year total outlay (excluding council tax and energy, which you would pay renting too) is approximately £170,000–£185,000 — comprising mortgage payments, maintenance, insurance, and transaction costs. Of that, approximately £44,000 is capital repaid (equity you own), leaving a true net 10-year housing cost of approximately £125,000–£141,000. This sounds large — because it is. The comparison to renting on the same property over 10 years (approximately £126,000 in rent at £1,050/month) shows why buying is broadly comparable in cash terms in most UK cities, while building equity that renting never does.
Most discussions of "the cost of buying a house" stop at the deposit and the solicitor's fees. That gives you day-one costs — but tells you almost nothing about what the property will actually cost you to own over the next decade. The mortgage payment alone is not the answer either; that ignores maintenance, insurance, the interest component of those payments, and the transaction costs of both buying and eventually selling.
This page works through all three phases of cost: the upfront transaction costs, the ongoing monthly and annual ownership costs, and the true 10-year total at three common UK property price points. For each, it distinguishes between costs that are unique to ownership (true homeownership costs) and costs you would pay regardless — like council tax and energy — so the comparison with renting is honest.
The three phases of homeownership cost
Everything you pay to get the keys: deposit, stamp duty, solicitor fees, survey, mortgage fees, insurance setup. Paid once, but substantial. The deposit is the biggest item but it is also equity — not a cost in the same sense.
Mortgage payments, buildings and contents insurance, maintenance and repairs, service charges (leasehold), and ground rent. These are the costs that accumulate silently and are most commonly underestimated.
Estate agent fees (1–3% of sale price), solicitor fees on sale (£1,000–£2,000), and any capital gains tax if applicable. Easily overlooked when calculating total ownership cost but unavoidable when you eventually sell.
Phase 1 — upfront costs broken down
These are the costs paid at or before completion. The deposit is by far the largest item but is an asset (equity in the property), not a sunk cost. Every other item is a genuine one-way expense.
| Cost item | £200k property | £300k property | £500k property | Notes |
|---|---|---|---|---|
| Deposit (10%) | £20,000 | £30,000 | £50,000 | Asset — recoverable as equity on sale |
| Stamp duty (FTB) | £0 | £0 | £10,000 | £0 FTB under £300k; 5% up to £500k |
| Solicitor fees (incl. searches) | £1,800 | £2,100 | £2,500 | Including local searches and Land Registry |
| Survey (Level 2) | £450 | £500 | £650 | Strongly recommended on all properties |
| Mortgage arrangement fee | £500 | £999 | £999 | £0–£1,499 depending on product chosen |
| Mortgage valuation fee | £0 | £0 | £0 | Often free on competitive deals |
| Buildings insurance (first year) | £180 | £220 | £320 | Required from exchange date |
| Removal costs | £600 | £800 | £1,200 | Highly variable — depends on volume and distance |
| Total non-deposit upfront costs (true sunk costs) | £3,530 | £4,619 | £15,669 | Excluding the recoverable deposit |
| Total cash needed day one (incl. deposit) | £23,530 | £34,619 | £65,669 | Including deposit |
FTB stamp duty rates apply (zero under £300,000). Home mover stamp duty is higher — use our stamp duty calculator for exact figures. Survey, solicitor, and arrangement fee figures are representative mid-range estimates.
Phase 2 — ongoing annual ownership costs
This is where the gap between "what you expect to pay" and "what you actually pay" is largest. Most buyers model the mortgage payment carefully. Very few model the maintenance budget with equal rigour — and maintenance is the cost that most consistently surprises owners in the first five years.
| Cost item | £200k property | £300k property | £500k property | Notes |
|---|---|---|---|---|
| Mortgage payment (10% dep, 4.5%, 25yr) | £11,100 | £16,700 | £27,800 | Repayment basis; includes capital element |
| Buildings insurance | £180 | £220 | £320 | Varies by property type, rebuild cost, location |
| Contents insurance | £120 | £150 | £250 | Optional but strongly recommended |
| Maintenance & repairs (1.5% of value/yr average) | £3,000 | £4,500 | £7,500 | Long-run average; highly variable year to year |
| Service charge (leasehold flats only) | £0–£2,500 | £0–£3,500 | £0–£5,000 | Freehold houses: £0. Leasehold flats: significant |
| Ground rent (leasehold, pre-2022 leases) | £0–£400 | £0–£400 | £0–£500 | New leases from 2022: peppercorn ground rent |
| Annual costs excluding mortgage (ownership-specific) | £3,300 | £4,870 | £8,070 | Excludes council tax and energy (paid whether renting or buying) |
| Total annual outlay (incl. mortgage) | £14,400 | £21,570 | £35,870 | Monthly: £1,200 / £1,798 / £2,989 |
Council tax (£1,500–£3,500/year) and energy bills are excluded — you pay these whether you rent or own and are not homeownership-specific costs. The mortgage payment includes a capital repayment component: approximately £3,600/year in year one on a £180k mortgage at 4.5%.
The maintenance budget — what 1.5% per year actually means
The 1–2% annual maintenance rule is an average across the full ownership period — it is not what you will spend every year. The reality is lumpy: years of minor costs punctuated by occasional large expenses. The table below shows the most common significant repair costs in the UK and their typical price range in 2025.
| Repair / replacement | Typical cost range | Typical lifespan | Annual provision |
|---|---|---|---|
| New roof (full reslate) | £5,000–£18,000 | 50–80 years | £100–£360/yr |
| Boiler replacement | £2,500–£5,500 | 10–15 years | £165–£550/yr |
| Full rewire | £3,000–£8,000 | 25–40 years | £75–£320/yr |
| Damp treatment (rising damp) | £2,000–£10,000 | One-off (if not addressed) | Variable |
| New windows (full house) | £4,000–£12,000 | 20–25 years | £160–£600/yr |
| Kitchen replacement | £5,000–£20,000 | 15–20 years | £250–£1,333/yr |
| Bathroom renovation | £3,000–£10,000 | 15–20 years | £150–£667/yr |
| Annual boiler service | £80–£150 | Annual | £80–£150/yr |
| Redecoration (interior, periodic) | £1,000–£5,000 | 5–10 years | £100–£1,000/yr |
| Garden maintenance / fencing / paving | £500–£5,000 | Variable | £200–£500/yr |
Costs are approximate 2025 national averages. Prices vary significantly by location, property size, and condition. London and South East typically 20–40% above these figures. New-build properties have lower initial maintenance costs due to builder warranties, but still require maintenance over a 10-year ownership period.
The true 10-year total cost — at three property price points
The most useful frame is the full 10-year cost — the total outlay including every pound spent on the property over a decade, with the capital equity built separated out so you can see the true net cost.
| Upfront sunk costs | £3,530 |
| 10-year mortgage payments | £111,000 |
| 10-year maintenance (1.5%/yr) | £30,000 |
| 10-year insurance | £3,000 |
| Total 10-year outlay (excl. deposit) | £147,530 |
| Of which: capital repaid (equity built) | −£35,800 |
| Of which: property price appreciation (3%/yr est.) | +£68,800 gain |
| Upfront sunk costs | £4,619 |
| 10-year mortgage payments | £166,600 |
| 10-year maintenance (1.5%/yr) | £45,000 |
| 10-year insurance | £3,700 |
| Total 10-year outlay (excl. deposit) | £219,919 |
| Of which: capital repaid (equity built) | −£53,700 |
| Of which: property price appreciation (3%/yr est.) | +£103,300 gain |
| Upfront sunk costs | £9,419 |
| 10-year mortgage payments | £277,800 |
| 10-year maintenance (1.5%/yr) | £75,000 |
| 10-year insurance | £5,700 |
| Total 10-year outlay (excl. deposit) | £367,919 |
| Of which: capital repaid (equity built) | −£89,500 |
| Of which: property price appreciation (3%/yr est.) | +£172,100 gain |
10-year mortgage payments based on 25-year repayment term at 4.5%. Capital repaid over 10 years calculated from amortisation schedule. Property appreciation estimated at 3% p.a. (approximate long-run UK average) — not guaranteed. Actual outcomes depend on location, property type, and market conditions. Excludes council tax, energy, and selling costs on eventual sale.
Leasehold vs freehold — a significant cost difference
One of the most overlooked ongoing cost differences in UK property is the distinction between freehold houses and leasehold flats. If you are buying a flat — which most first-time buyers in cities do — you are almost certainly buying leasehold. The additional annual costs are significant and need explicit modelling.
| Annual cost | Freehold house | Leasehold flat (typical) | Difference |
|---|---|---|---|
| Buildings insurance | £180–£300 (you arrange) | Included in service charge | — |
| External maintenance | Your responsibility / your timing | Managed by freeholder / management co. | — |
| Service charge | £0 | £1,200–£4,000/year | +£1,200–£4,000 |
| Ground rent (pre-2022 leases) | £0 | £0–£500/year | +£0–£500 |
| Reserve / sinking fund contribution | £0 (you manage your own reserves) | £200–£1,000/year | +£200–£1,000 |
| Occasional major works levy | Your choice of timing and contractor | Assessed by management company — no control | Variable |
| Annual leasehold premium over freehold | — | £1,400–£5,500/year | £14,000–£55,000 over 10 years |
Service charges vary enormously. A modern well-managed block might charge £1,200–£1,800/year. A Victorian conversion with deferred maintenance and a poor management company can cost £3,500–£5,000+ annually, with unexpected major works levies on top. Always obtain three years of service charge accounts before making an offer on a leasehold property.
Phase 3 — selling costs (often forgotten)
Most homeownership cost analyses stop at the ongoing annual costs. But when you eventually sell, you incur transaction costs again — and these are often larger than the buying costs. Including selling costs in your true total cost of ownership changes the picture meaningfully.
| Selling cost | £200k sale | £300k sale | £500k sale |
|---|---|---|---|
| Estate agent fee (1.5% incl. VAT) | £3,000 | £4,500 | £7,500 |
| Solicitor fee on sale | £900 | £1,100 | £1,500 |
| Energy Performance Certificate (if needed) | £100 | £100 | £100 |
| Capital gains tax (if BTL or second home) | N/A for main home | N/A for main home | N/A for main home |
| Total selling costs | ~£4,000 | ~£5,700 | ~£9,100 |
No CGT on main residence (principal private residence relief). Estate agent fees vary — negotiate, and consider online agents (£1,000–£2,000 fixed) for straightforward sales. Including selling costs, the total transaction overhead for buying and then selling a £300,000 property over 10 years is approximately £10,300 in sunk fees.
The complete true cost summary — buying vs renting over 10 years
To make the homeownership cost meaningful, it needs to be compared to the alternative: renting the same property for 10 years. The two columns below use the £300,000 property as the base case.
| Upfront fees (sunk costs) | £4,619 |
| 10yr mortgage payments | £166,600 |
| 10yr maintenance (1.5%/yr) | £45,000 |
| 10yr insurance (buildings + contents) | £3,700 |
| Selling costs (est. at 10yr sale) | £5,700 |
| Total outlay over 10 years | £225,619 |
| Capital repaid (equity built via payments) | −£53,700 |
| Property appreciation (3% p.a. over 10yr) | +£103,300 gain |
| Net financial position after 10 years | Ahead by ~£70,000 vs renting |
| Year 1–2 rent (£1,250/mo) | £30,000 |
| Year 3–4 rent (£1,275/mo) | £30,600 |
| Year 5–6 rent (£1,300/mo) | £31,200 |
| Year 7–8 rent (£1,326/mo) | £31,824 |
| Year 9–10 rent (£1,353/mo) | £32,472 |
| Total rent paid over 10 years | £156,096 |
| Deposit invested at 5% p.a. for 10yr | £30k → £48,900 |
| Net financial position after 10 years | £0 housing asset; ~£49k in savings |
| Vs buyer position | ~£70,000 behind |
The buying scenario outperforms renting by approximately £70,000 over 10 years in this model, driven primarily by the £103,300 property appreciation at 3% p.a. If property prices are flat (0% appreciation), the two positions are broadly similar — the buyer is ahead on equity built through repayments but behind on total cash outlay. If property prices fall 15%, renting becomes the better financial outcome over 10 years. This sensitivity to the price appreciation assumption is the primary risk in homeownership as a financial decision. The non-financial benefits of ownership — stability, security, freedom to modify — are separate from this calculation.
Frequently asked questions
-
How much does it really cost to buy a house in the UK beyond the deposit?For a first-time buyer purchasing under £300,000 (zero stamp duty), the non-deposit upfront costs are typically £3,500–£5,500 — including solicitor fees, survey, mortgage arrangement fee, and insurance. For properties between £300,000 and £500,000, stamp duty adds up to £10,000, bringing total upfront costs to £3,500–£15,500. Home movers pay more stamp duty. Use our hidden costs guide for a full itemised breakdown.
-
How much should I budget for ongoing home maintenance?The standard rule of thumb is 1–2% of the property's value per year averaged over the full ownership period. On a £250,000 house, that is £2,500–£5,000/year. In practice costs are lumpy — a boiler replacement (£2,500–£5,500), roof work, or rewire arrives infrequently but at significant cost. Newer properties have lower initial maintenance but are not cost-free. Under-budgeting for maintenance is the single most common financial mistake new homeowners make.
-
What are the hidden ongoing costs of owning a house?Beyond the mortgage, the main ongoing ownership costs are buildings insurance (£180–£400/year), maintenance and repairs (£2,000–£8,000/year on average), and for leasehold flats, service charges (£1,200–£4,000+/year). Many buyers model the mortgage payment carefully but treat maintenance as zero until something breaks. The true annual cost of ownership typically runs £3,000–£8,000 above the mortgage payment alone.
-
Is it cheaper to rent or buy in the UK over 10 years?On a like-for-like comparison in most UK cities, buying builds significantly more wealth over 10 years — primarily through equity accumulation and capital appreciation — even though total cash outlay is higher. The calculation is sensitive to property price growth: if prices rise at the long-run UK average of 3% p.a., buying outperforms renting by £50,000–£100,000 over 10 years on a typical UK property. If prices are flat for a decade, the two positions are broadly comparable. Our renting vs buying guide models this in detail.
-
What are the costs of selling a house in the UK?Selling a house costs approximately £4,000–£10,000 depending on property value. The main costs are estate agent fees (typically 1–1.5% of sale price including VAT), solicitor fees on sale (£900–£1,800), and an EPC if needed. No stamp duty is paid on the sale. No CGT on your main home. Including both buying and selling costs, the total transaction overhead for buying and eventually selling a £300,000 property is approximately £10,000–£15,000.
