Two terraced houses go up for sale in the same week. Both list at £180,000. Both rent for around £900 a month. On paper, they share the same gross yield: a healthy 6%. You’d be forgiven for treating them as roughly the same investment. But once you’ve factored in service charges, longer voids, a higher management fee for one of them, and the inevitable boiler replacement, the net returns can sit a full two percentage points apart. One quietly loses money. The other quietly makes it. The headline number told you nothing useful.
That gap between what yield looks like and what it actually delivers has widened sharply over the last few years. Higher mortgage rates, the Section 24 mortgage interest restriction, the 5% buy-to-let stamp duty surcharge, and tighter EPC rules have all chipped away at real returns. According to Zoopla’s latest regional data, the average UK gross rental yield sits at around 5.8%. Yet on a typical mortgaged buy-to-let, the net figure often lands closer to 2–3% once costs are honestly accounted for.
This guide walks you through what yield really is, how to calculate gross and net correctly, what counts as a good yield in, and importantly, when yield stops being a useful number on its own. By the end, you’ll have a clearer way to assess properties at acquisition, spot underperformers in your existing portfolio, and avoid the most common mistake landlords still make: pricing a deal on a flattering headline figure.
What Is Yield in Property?
Before we get into the calculations, it helps to nail down what yield actually measures and what it doesn’t. Most arguments about yield come from people using slightly different definitions, so let’s start clean.
Rental yield, defined
Rental yield is the annual rental income from a property, expressed as a percentage of the property’s value. It gives you a standardised way to compare income performance across properties of different sizes, prices, and locations.
Two formulas matter, and you’ll meet both throughout this guide:
- Gross rental yield = (Annual rental income ÷ Property value) × 100
- Net rental yield = ((Annual rental income − Annual operating costs) ÷ Total investment) × 100
That’s the whole foundation. Everything else is detail i.e., what to put in each formula, when to trust the result, and when to look beyond it.
Why yield matters for landlords
Yield earns its place in your toolkit because it does three jobs nothing else does as cleanly. First, it shortlists deals. When you’re scrolling through Rightmove on a Sunday evening, gross yield filters the maybes from the no-chances in seconds. Second, it benchmarks performance. Tracking yield across your existing portfolio surfaces the underperformers that your monthly cash flow report tends to hide. Third, it underpins lender stress-tests – most buy-to-let mortgage decisions are anchored to rental cover ratios that flow directly from yield.
What yield doesn’t do is capture capital growth, finance costs, or tax. We’ll come back to those limitations later on. For now, just hold them in mind. Yield is one input into a property decision, not the whole decision.
Gross Rental Yield Explained
Gross yield is the simpler of the two figures, and the one you’ll see quoted everywhere from estate agent listings to property news headlines. It’s useful, but only if you understand exactly what it leaves out.
The gross yield formula
| Gross Rental Yield (%)(Annual Rental Income ÷ Property Value) × 100 |
Two inputs only. Both look obvious, but they trip people up surprisingly often:
- Annual rental income is the rent the property collects in 12 months, before any costs come out. If you charge £900 a month, that’s £10,800. Don’t be tempted to deduct anything yet.
- Property value is either the purchase price (when you’re assessing a deal) or the current market value (when you’re reviewing existing performance). Pick one and stick with it across your portfolio so comparisons stay clean.
A worked example: a northern buy-to-let
Let’s run a real-feeling example you can carry through the rest of the article. Picture a three-bedroom terrace in Sunderland (a region currently at the top of every yield league table) bought for £130,000 and let at £825 per calendar month.
- Annual rental income: £825 × 12 = £9,900
- Property value: £130,000
- Gross yield: (£9,900 ÷ £130,000) × 100 = 7.6%
A 7.6% gross yield looks impressive, and in northern markets, it’s perfectly plausible. Hold on to that number. We’ll come back to the same property and see what happens once costs land.
When to use gross yield (and when not to)
Gross yield earns its keep at the start of a deal, not the end of one. Use it to triage opportunities, compare properties at a glance, and benchmark a region against the national average. It’s the right tool for shortlisting.
Where it falls down is when landlords rely on it as their headline portfolio number. That’s the single biggest mistake we see in this space: gross yield flatters performance, hides margin erosion, and makes it harder to spot the property that’s quietly costing you money each month. If you only track one yield figure across your portfolio, it should not be the gross one.
Net Rental Yield Explained
If gross yield tells you a property’s potential, net yield tells you what actually arrives. It’s the figure that survives contact with the reality of agent fees, repairs, voids, insurance, the lot. For any decision more serious than a shortlist, this is the number you want.
The net yield formula
| Net Rental Yield (%)((Annual Rental Income − Annual Operating Costs) ÷ Total Investment) × 100 |
Two of the three inputs need a bit more thought than they do for gross yield. The annual rental income is the same. The other two carry more weight.
- Annual operating costs cover every recurring cost of letting the property.
- Total investment ideally includes the purchase price plus all your acquisition costs: stamp duty, legal fees, surveys, refurbishment. Many landlords use just the property value, and end up with a net yield that’s quietly inflated.
The rule of thumb here is straightforward: the more conservatively you load the costs and the investment, the more useful your net yield becomes.
What costs to include in net yield
Get this section right and your net yield will tell you something genuine. Get it wrong and you’re just doing gross yield in disguise. Here are the eight categories that matter, with realistic 2026 UK ranges:
| Cost category | What to include | Typical UK range (2026) |
|---|---|---|
| Letting & management | Letting agent fees, full management fees, tenant find fees | 8–15% of rent (full mgmt); £400–£800 (let-only) |
| Repairs & maintenance | Reactive repairs, planned maintenance, redecoration | Budget 1–2% of property value annually |
| Voids | Periods between tenants where rent isn’t received | Allow 4–6 weeks per year (~8–11% of rent) |
| Insurance | Landlord buildings, contents, rent guarantee, liability | £200–£600 per year |
| Compliance & safety | Gas Safety, EICR (every 5 yrs), EPC (every 10 yrs), smoke/CO alarms | £100–£300 per year amortised |
| Service charges & ground rent | Leasehold properties only | £500–£3,000+ per year (highly variable) |
| Licensing | Selective and HMO licensing, where applicable | £500–£1,500 per 5 years (varies by council) |
| Accounting & admin | Bookkeeping, accountancy, software | £150–£500 per year per property at scale |
A few of these deserve a closer look. Letting agent fees vary enormously depending on whether you’re using let-only, fully managed, or somewhere in between. Pick the figure that matches your actual setup, not the cheapest one you’ve seen advertised. Voids almost always cost more than landlords plan for; if you’re not allowing four weeks a year as a baseline, you’re optimistic. And if you’re managing leasehold flats, service charges can swallow your net yield entirely if you don’t price them in honestly.
Should mortgage interest be included in net yield?
The textbook answer: pure rental yield doesn’t include finance costs. Yield measures the income performance of the asset itself, separate from how you’ve chosen to fund it. A property’s yield should be the same whether you bought it cash or with a 75% loan-to-value mortgage.
In practice, plenty of landlords (and a few lender calculators) include mortgage interest in what they call a “true net yield” because that’s what actually lands in their bank account each month. There’s no wrong answer, but there is a useful one: keep yield as a property-level metric without finance, and use ROI or cash-on-cash return when you want the finance-inclusive view. You can shortcut the maths with a free ROI calculator when you’re ready to layer mortgages and capital growth into the picture.
One important wrinkle: even if you do choose to factor in mortgage interest, remember that HMRC’s Section 24 rules mean you can’t simply deduct it as an expense for tax purposes. It now sits as a 20% basic-rate tax credit instead. That’s a big part of why net yield and post-tax cash flow have drifted apart for higher-rate landlords.
A worked example: same property, net yield
Let’s go back to that Sunderland terrace. Same £130,000 purchase, same £9,900 annual rent, same 7.6% gross yield. Now we apply real costs:
| Item | Annual £ |
|---|---|
| Annual rental income | £9,900 |
| Letting agent (10% management) | −£990 |
| Repairs & maintenance (1.5% of property value) | −£1,950 |
| Void allowance (4 weeks) | −£760 |
| Insurance | −£300 |
| Compliance (gas/EICR/EPC amortised) | −£200 |
| Net annual income | £5,700 |
| Total investment (£130,000 price + ~£8,200 SDLT/legal/survey) | £138,200 |
| Net rental yield = (£5,700 ÷ £138,200) × 100 | 4.1% |
The same property that looked like a 7.6% yielder is actually working at 4.1% before we’ve even mentioned a mortgage. That’s a 3.5 percentage point gap, or, put differently, the gross figure overstated real income performance by 46%. This isn’t a freakish example; it’s roughly what most mortgaged or fully managed buy-to-lets look like once you stop being polite with the numbers. If your portfolio reporting shows a gross yield that hasn’t been challenged this way, it’s worth doing the exercise on every property.
Gross vs Net Yield: A Side-by-Side Comparison
If you take one image away from this article, this is the table to bookmark. It’s the quickest way to remember which figure to use, when to use it, and what the realistic UK numbers actually look like in 2026.
| Gross yield | Net yield | |
|---|---|---|
| What it measures | Headline income against property value | Real income performance after running costs |
| Includes operating costs? | No | Yes |
| Includes mortgage interest? | No | Not in standard definition; some landlords add it |
| Best for | Shortlisting and quick comparisons | Decision-making and portfolio reporting |
| Risk of using on its own | Overstates real returns; flatters underperforming assets | Lower risk; closer to actual cash performance |
| Typical UK figure (2026) | ~5.8% national average | ~3–4% on managed, mortgage-free BTL; 1–3% on mortgaged |
The pattern across both columns tells the story: gross gets you started, net gets you serious. If you’re at the property-hunting stage, lean on gross. The moment you’re past the shortlist, switch to net and don’t look back.
When Yield Is Misleading on Its Own
Here’s the part most yield articles skip, and the part that actually matters most if you’re scaling a portfolio. Yield is a useful number, but it has real blind spots. Treat it as a single dial on a dashboard rather than the dashboard itself.
High yield can mask real risk
Yield is a snapshot. It says nothing about tenant demand, void risk, capital growth, employment trends, or local supply. A 9% gross yield in a postcode with weak demand can return less in practice than a 5% yield in a high-demand area, once you’ve factored in turnover and the gaps between tenancies.
This shows up most starkly in some of the highest-yielding postcodes where headline yields are eye-catching but tenant turnover is higher, arrears risk is elevated, and capital appreciation has historically lagged. None of that means avoid those areas. It just means yield alone won’t tell you whether they’re right for you. Pair it with a serious read on how to manage void periods before committing capital.
Yield ignores capital growth
A London flat at 4.5% gross can comfortably outperform a Sunderland terrace at 8% over a ten-year hold once capital growth lands. Wealth-building landlords with longer time horizons need to weigh both sides. Yield only tells you about income; it’s silent on the asset value sitting underneath it.
This is the cleanest reason to graduate from yield to ROI as your primary portfolio metric. ROI captures both income and growth, and it’s the figure that actually answers “is this property making me wealthier?” which is, after all, the question yield can only partly answer.
Yield doesn’t account for mortgage costs or tax
On a mortgaged buy-to-let, with current rates running at 4.5 – 6%, a 5% gross yield can produce negative cash flow before any other cost lands. That’s not a hypothetical. It’s the maths a lot of leveraged landlords are quietly living with right now. Layer on the Section 24 changes, and a higher-rate taxpayer can see net yield and post-tax cash flow drift even further apart.
If you’re modelling a new acquisition seriously, you’ll want to stress-test it against rate rises, void scenarios, and lower-than-expected rents — not just plug in a single yield figure and hope. Software helps here, but so does the simple discipline of asking “what does this look like at 6.5% rates and 8 weeks of voids?” before signing anything.
Yield doesn’t reflect compliance burden
HMOs typically post the highest gross yields you’ll see anywhere (10%+ is common) but those numbers carry a heavy load of fire safety, compliance, refurbishment, and management cost that standard buy-to-lets don’t. The real cost of running an HMO often pulls the net figure right back into line with regular BTL.
And with the Renters’ Rights Act now creating new landlord obligations from 1 May 2026, the per-property admin and compliance time has increased meaningfully across every type of let – not just HMOs. Most yield calculations don’t capture that time cost. If you’re managing 30 properties solo, the hours add up fast, and they’re a real input into whether your yield is actually “good” once you’ve paid yourself for the work.
What Is a Good Rental Yield in 2026?
It’s the natural follow-up question, and the honest answer depends on whether you’re talking gross or net, where the property sits, and how you’ve funded it. That said, a few working benchmarks help.
The quick answer
For UK buy-to-let in 2026, a gross yield of 5 – 8% is typical, anything above 6% is considered strong, and 8%+ is excellent. For net yield, 3 – 4% is acceptable on a managed property, 5%+ is strong on a managed mortgage-free BTL, and many mortgaged landlords realistically see 1 – 3% net once everything’s accounted for.
Those bands are a starting point, not a verdict. A 4.5% gross yield in central London can be a perfectly sensible long-term hold if you’re betting on capital growth, and a 9% yield in a low-demand postcode can be a value trap. Context matters more than the number.
Average yields by UK region
Where you buy still drives the headline yield more than anything else. Here’s how the regions stack up based on early-2026 data – useful as a benchmark when you’re comparing your own properties to the wider market:
| Region | Average gross yield | Notes |
|---|---|---|
| North East | ~7.9% | Highest yields nationally; lowest property prices |
| Scotland | ~7.6% | Glasgow notably stronger than Edinburgh |
| North West | ~6.8% | Liverpool and Manchester remain hotspots |
| Wales | ~6.5% | Cardiff growing as a major rental city |
| Yorkshire & Humber | ~6.5% | Bradford and Hull lead on yield |
| West Midlands | 5.5–6.5% | Birmingham well-balanced for yield + growth |
| East Midlands | ~5.8% | Nottingham and Leicester strongest |
| South West | ~5.5% | Lower yields, capital-growth focused |
| South East | ~5.6% | Below-average yield; high entry prices |
| East of England | ~5.6% | Yield improving as prices have softened |
| London | ~5.1% | Lowest yields nationally; capital growth play |

A good yield depends on your strategy
There’s no universal definition of “good”, and that’s actually a useful realisation rather than a frustrating one. If you’re income-focused (and especially if you’re approaching retirement), weight yield heavily and aim higher. If you’re building wealth over a long horizon, you can accept lower yields in exchange for stronger capital growth potential. If you’re an HMO operator, you’ll be benchmarking against 10%+ gross figures that net out closer to standard BTL once compliance, voids, and refurbishment land.
A useful mental model: define what “good” looks like for you, then test every property against that bar. Anything above the bar earns its place. Anything below needs a clear reason (usually capital growth potential) for staying in your portfolio.
Want to push your yields higher?
Knowing what a good yield looks like is one thing. Actually moving the needle on your portfolio is another. And it usually comes down to a handful of practical levers: smarter rent reviews, faster turnarounds between tenants, sharper cost control, and small refurbishments that justify higher rents. Our free Maximise Your Rental Yields Guide walks through the tactics that work in the current market, with worked examples you can apply to your own properties this quarter. If you’d rather see the field-tested list, we’ve also collected 33 specific ways to boost rental yields across both standard BTL and HMO setups.
How to Track Yield Across a Portfolio
Calculating yield once at purchase is the easy part. Tracking it across 20, 50, or 100 properties through rent reviews, refurbishments, tenant changes, and shifting cost bases is where most landlords lose visibility. And without that visibility, the underperformers go unnoticed.
Yield is a lagging indicator unless you track it
Here’s the trap. The strong properties in your portfolio quietly subsidise the weak ones. Your overall portfolio average looks fine. Cash flow is positive. Nothing flags. But buried inside that average is a property running at 2% net while another is running at 6%, and you’ve been treating them as equivalent for two years. Without ongoing per-property tracking, the laggards never surface.
It’s worth understanding why rental yield is so important as a portfolio-level metric, not just a deal-level one. The landlords who consistently outperform tend to be the ones who recalculate yield on every property, every quarter, and act on what the numbers show.
What good yield tracking looks like
Done well, portfolio yield tracking gives you four views at any time:
- Per-property: live gross and net yield, updated as rent and costs change.
- Portfolio-level: weighted average, range, and outliers (both top and bottom).
- Benchmarked: compared to regional averages and to your own targets.
- Action-linked: properties below threshold flagged for rent review, refurbishment, or disposal.
If you’re getting all four out of a spreadsheet, you’re either highly disciplined or you’ve got a small portfolio. Most landlords with more than ten properties find the spreadsheet starts to creak somewhere around year two.
Beyond spreadsheets
For a handful of properties, a well-built spreadsheet is workable. For 20+ tenancies, manual tracking becomes the source of most reporting errors. That’s roughly the point at which dedicated buy-to-let portfolio software starts to pay for itself, because it tracks rent, expenses, and per-property yield automatically as transactions land. Your portfolio yield is current, not quarterly.
There’s also a forward-looking reason this matters: with MTD compliance arriving and the new PRS Database expected to require per-property reporting, having your yield, income, and cost data already structured per property puts you a long way ahead of where most landlords currently sit.
Frequently Asked Questions
A few short answers to the questions that come up most often around yield calculations. If you’re after a quick reference, this section’s the one to bookmark.
Is a 5% rental yield good?
5% is a reasonable benchmark for most UK regions. Average to slightly above average outside London. Whether it’s “good” depends on whether it’s gross or net, the property’s location, and whether it’s mortgaged. On a fully mortgaged BTL, a 5% gross yield often produces only 1–2% net cash return after costs.
How do you calculate rental yield?
Gross yield = (annual rental income ÷ property value) × 100. Net yield = ((annual rental income − annual costs) ÷ total investment) × 100. Use gross to compare deals quickly; use net to assess actual performance.
What’s the difference between yield and ROI?
Yield measures income performance against property value. ROI measures total return on the cash you’ve actually invested, and includes capital growth and finance costs. ROI is the more complete metric; yield is the simpler one for fast comparison.
Should mortgage interest be included in net yield?
Standard definitions of net yield don’t include mortgage interest. Yield measures the asset’s income performance, not how you’ve funded it. For a finance-inclusive view, switch to ROI or cash-on-cash return instead.
Are HMO yields really higher?
HMO gross yields are typically 8 – 12%, which is significantly higher than standard BTL. Net yields land closer to standard BTL once you’ve factored in higher management, compliance, void, and refurbishment costs.
Does stamp duty affect rental yield?
Yes, indirectly. The 5% buy-to-let stamp duty surcharge increases your total investment, which reduces net yield even though it doesn’t appear on the income side. HMRC’s SDLT guidance has the current rates and thresholds.
Final Thoughts
Yield is the cleanest like-for-like metric you have for comparing rental income performance across very different properties. But only when you calculate it honestly. Gross yield earns its place at the shortlist stage. Net yield earns its place everywhere else. Most landlords default to gross and quietly underestimate the gap, and in 2026 that gap is wider than it’s been in years.
The landlords who consistently outperform aren’t necessarily the ones buying the highest-yielding properties. They’re the ones tracking yield rigorously across every property they own, spotting underperformers early, and acting on what the numbers show. Whether that’s a rent review, a refurbishment, or a sale. The number is only useful when you do something with it.If you want to start putting that into practice, two next steps are worth your time. First, download our free Maximise Your Rental Yields Guide for the practical tactics (rent reviews, void reduction, cost control) that actually move yields.
