Why a 7% Yield Isn't Worth the Risk Without Security
A high yield is not automatically bad. An unexamined one is. Here is what the extra percentage points are compensating you for, and the questions that separate the two.
A yield is a price, not a prize. When a property pays 7% and a similar-looking one pays 4%, the market isn’t being careless with the cheap one. It’s charging less for it because something about it’s worse, and the extra three points are what buyers demanded before they would take that something on.
The mistake isn’t buying a high yield. It’s buying one without finding out what it’s compensating for. My own Hunt Lane purchase in Bentley ran at 12.7% gross, and it was a good deal. The difference between that and a bad 12.7% is entirely in what I knew before I bought it.
First, the honest case for high yield
The argument for chasing yield is stronger than sourcers who sell “prime” stock like to admit.
Income compounds. A property returning 8% net rather than 4% net doubles the cash you can redeploy, and the second property you buy with that cash is the real return. Cheap properties also carry less capital at risk per unit: buying four houses at £70,000 spreads tenant risk, void risk and area risk across four streets instead of concentrating it in one £280,000 flat. Low-value stock in the north is often bought with cash, which removes interest rate risk entirely. And the buy-to-let case in high-value southern markets frequently rests on capital growth, which is a forecast, while rent is a payment that arrives.
None of that’s wrong. So when someone tells you a 7% yield is inherently reckless, they’re usually selling something with a 4% yield.
What the extra points are paying for
Yield is the market’s discount for five specific problems. Price each of them for the actual property.
Tenant quality and rent collection. The relevant number isn’t the rent, it’s the rent you actually receive. Arrears are the most common reason a real return misses a projected one, and the process for dealing with them is now slower than most overseas buyers assume. Since the Renters’ Rights Act 2025 took effect, section 21 no-fault possession has gone: to recover a property you need a stated ground, evidence, and a notice period. The mandatory arrears ground requires the arrears to have reached a set level and carries its own notice period before you can even start a claim, and the court queue runs after that. Ask who lives there now, what they pay, whether they have ever missed, and how long a possession claim takes in that county court.
Void periods. Every month empty costs you a twelfth of the annual rent plus council tax, which falls on the owner when a property is unoccupied. A high-yield area is often high-yield because demand is thin. Two months empty a year turns 12% into 10% before you have spent anything on it.
Maintenance load. Cheap houses are usually old houses. Old houses have solid walls, original roofs, and heating systems near the end of their life. The number that matters isn’t the purchase price, it’s the purchase price plus everything the property will need in the first three years. A boiler, a rewire and a roof aren’t unusual on pre-1930 terraced stock, and they arrive as lump sums, not as a smooth annual percentage.
Energy standards. You cannot let a property in England or Wales with an EPC below band E, and improvements up to a £3,500 cap are your responsibility if it falls short. Government has also stated an aim for as many privately rented homes as possible to reach band C or equivalent by 2030, without the implementing detail yet published. On a solid-walled terrace that is a real, and potentially large, capital number. The current rules are on GOV.UK (checked 25 August 2026).
Exit liquidity. This is the one that gets skipped. Ask who buys this property from you in ten years. If the answer is only other investors, you’re exposed to investor sentiment alone, and that market thins fast when lending tightens. If owner-occupiers also want the street, you have two buyer pools. Streets where nobody lives by choice have both high yields and thin exits, and those two facts are the same fact.
Area trajectory. Not what the street is now, what it’s heading towards. Employment, school catchment, tenure mix, how many properties on that road are already rented. A road that is 90% rented behaves differently to one that is 30% rented, and no yield calculation shows you that.
The arithmetic, run properly
Gross yield is annual rent divided by purchase price. It’s a screening tool and nothing more. Here’s what happens to a real one when you finish the sum.
Hunt Lane cost my client £61,500 and lets at £650 a month, so £7,800 a year. That’s a 12.7% gross yield. Now the deductions. Every figure below is an illustration to show the shape of the calculation, not a quote. Get your own numbers in writing.
| Line | Illustrative annual figure |
|---|---|
| Rent received | £7,800 |
| Letting agent management, say 10% plus VAT | (£936) |
| Buildings insurance | (£300) |
| Repairs and maintenance allowance | (£900) |
| Safety certificates, annualised | (£150) |
| Void allowance, one month | (£650) |
| Net rent | £4,864 |
On the purchase price alone that is a 7.9% net yield. Then add the capital you actually deployed. On a £61,500 second property, Stamp Duty Land Tax sits in the 0% band on the standard rates, but the 5% additional property surcharge still applies, giving £3,075, and a non-UK resident buyer adds a further 2%, so £1,230 more. Add conveyancing, a survey and any sourcing fee, and the real capital in is meaningfully above £61,500, so the real net yield is lower again. Rates checked on GOV.UK on 25 August 2026; they change, and how they apply to you depends on your circumstances, so confirm with your solicitor.
The point isn’t that 12.7% was a lie. It’s that 12.7% gross became something closer to 7% once the sum was finished, and 7% honestly arrived at is worth more than 12% that hasn’t been checked. Hunt Lane was bought for an overseas investor who never visited the country, which means every one of those numbers had to be right without them being able to look. You can read the full deal here.
The questions that separate an examined yield from an unexamined one
If a sourcer or agent presents you with a high yield, ask these. The answers tell you more than the headline number.
- Is that gross or net, and what is deducted to get from one to the other?
- Is the rent achieved, or estimated? If achieved, show me the tenancy agreement and the rent account.
- What is the EPC rating today, and what does it cost to get it to a C?
- What has been spent on the property in the last five years, and what is due next?
- What has sold on this street in the last two years, and to whom?
- How long do properties sit on the market here before they sell?
- What percentage of this street is rented?
- If the tenant stopped paying tomorrow, what is the realistic timeline and cost to recover the property?
A sourcer who has done the work will have the answers. One who hasn’t will tell you the yield again.
What to do next
Treat yield as the first filter, never the last. Screen on gross, decide on net after voids, maintenance and the energy standards work, and refuse anything where you can’t describe the exit buyer in a sentence.
I publish the numbers on the purchases I’ve written up in full on case studies. If you want the longer version of this argument, security versus high yield sets out the trade-off, and cashflow priority versus wealth preservation covers which of the two you should actually be optimising for.
