The Complete Guide to Buying vs Renting in the UK (2026)
The usual way to compare buying and renting is to put the mortgage payment next to the rent. On a £350,000 home with a 10% deposit, a 25-year mortgage at 5.6% costs £1,953 a month. If the same home rents for £1,500, buying looks £453 a month dearer and the conversation stops there.
That comparison leaves out both halves of the real question. The buyer is building equity with part of every payment, and the property may rise in value. The renter still has the deposit and the stamp duty, and can invest them. What matters is which of the two ends up with more after the number of years you actually plan to stay.
The calculator above answers that for your own numbers. This guide explains what goes into it, where the figures come from, and how much the answer moves when the assumptions change.
What Buying Costs Before You Get the Keys
The deposit is not the only cash you need. A first-time buyer purchasing at £350,000 with a 10% deposit faces roughly this:
| Cost | £350k example | Basis |
|---|---|---|
| Deposit (10%) | £35,000 | Becomes your equity |
| Stamp duty, first-time buyer | £2,500 | A home mover pays £7,500 |
| Conveyancing with disbursements | £1,509 | Average, Q2 2026 |
| Level 2 survey | about £700 | Range is £400 to £1,000 |
| Mortgage product fee | £999 | Typical on the rates quoted |
| Removals, three-bedroom home | £792 | Average local move, August 2026 |
| Total upfront | about £41,500 | 12% of the price |
About £6,500 of that is tax and fees you never get back. Our total cost of buying guide takes each line in turn and gives the source for every figure.
Costs that carry on after you move in
An owner also pays for maintenance, buildings insurance and, on a leasehold property, a service charge. The calculator's maintenance field defaults to 1% of the property's value a year, which is £3,500 on this example, or about £292 a month. A renter pays none of these. Council tax is the same either way, so it does not affect the comparison.
The Case for Renting: Capital You Can Use
Renting is not automatically the worse financial choice. A renter who does not buy keeps the deposit and the stamp duty. For the first-time buyer above that is £37,500. Invested at 7% a year it would grow to about £73,800 over 10 years. A Stocks and Shares ISA shelters that growth from tax, within the £20,000 annual ISA allowance.
Two cautions apply. A 7% return is an assumption, not a promise, and investments can fall as well as rise. And the argument only works if the money is actually invested. A deposit that sits in a current account, or gets spent, does none of this.
How Much the Answer Depends on House Price Growth
The single most important input is the one nobody can know: how fast the property rises in value. Running the calculator at its defaults (£350,000, 10% deposit, 5.6%, £1,500 rent rising 3% a year, 1% maintenance, 7% investment return, 10 years, not a first-time buyer) and changing only the growth rate gives:
| Annual property growth | Owner's net worth after 10 years | Renter's portfolio after 10 years | Result |
|---|---|---|---|
| 3.5% (the default) | £256,206 | £188,127 | Buying ahead from year 2 |
| 2.5% | £210,526 | £185,199 | Buying ahead from year 3 |
| 1.4% | £164,701 | £182,162 | Renting ahead |
At 3.5% growth buying is well ahead. At 1.4%, which is the actual UK rate for the year to July 2026, renting finishes about £17,500 ahead after 10 years. The picture changes with time: hold that 1.4% scenario for 25 years and buying overtakes in year 22, because the mortgage payment stays fixed while rent keeps rising. Run your own figures at more than one growth rate, and over the number of years you really expect to stay, before drawing a conclusion.
When Buying Tends to Win
- You are staying for a long time. The stamp duty and fees are a fixed cost of each purchase. The more years you spread them over, the less they matter.
- Rent is close to the mortgage payment. If renting saves you little each month, the renter has little to invest and the owner's capital repayment does the work.
- Prices rise steadily where you are buying. National averages hide large differences. In the year to July 2026 prices rose 4.9% in the North East and fell 3.3% in London.
- You will not be forced to sell in a falling market. Owning assumes you can sit through a bad few years.
When Renting Tends to Win
- Prices are high relative to rents. The average London home cost £550,037 in July 2026 and the average London rent was £2,332 a month. That price is nearly 20 years of rent. Across the UK the figure is about 16 years (£273,000 and £1,400 a month).
- You expect to move within a few years. Each purchase brings a fresh round of stamp duty and fees. On a £350,000 home that is £7,500 of stamp duty alone for a home mover.
- You really will invest the difference. The calculator assumes the renter invests every pound saved. Be honest about whether that describes you.
The Market in October 2026
- Mortgage rates: the average five-year fix was 5.53% on 3 October 2026, and 5.63% at 90% loan to value. That is why the calculator's default rate is 5.6%. Guides written early in 2026 often quote rates more than a point lower.
- House prices: the average UK home sold for £273,000 in July 2026, up 1.4% on the year. England averaged £293,000, Wales £215,000 and Scotland £196,000.
- Rents: the average UK private rent was £1,400 a month in August 2026, up 3.8% on the year. Rent inflation was highest in the North East and North West at 5.8% and lowest in the South East at 3.0%. The calculator assumes rent rises 3% a year unless you change it.
