Leeds's 7.4% yield claim hides a £242 monthly loss

You keep coming back to the same line on the yield table: 7.4%, sitting well above the rest of your Yorkshire portfolio, in a postcode cheap enough that the numbers look almost too good. Leeds's LS11 has been doing exactly that all year, an average purchase price low enough to make the headline yield spectacular, in a city that already has a genuine reputation for strong professional and student rental demand. The question isn't whether that 7.4% is real. It's what's left of it once you own the mortgage, the tax bill and the EPC clock.

Run the actual numbers on an LS11 terrace bought today at 75% loan-to-value, and the picture changes fast. A higher-rate taxpayer ends up roughly £242 a month worse off once you count the current buy-to-let mortgage rate, Section 24's tax treatment, and the £10,000 EPC bill every rented home in England faces by 1 October 2030. The 7.4% yield is genuine. The monthly loss sitting underneath it is too.

Why LS11's 7.4% yield looks so different from the rest of Leeds

LS11's average buy-to-let purchase price sits at roughly £138,500 against a typical monthly rent of £854, producing a 7.4% gross yield (buy-to-let market analysis, 2026). Compare that with Leeds's city-wide average price of roughly £249,000 (HM Land Registry/ONS UK House Price Index, June 2026, provisional) and it's clear why the postcode stands out: rents across the city have kept pace with demand from students and young professionals priced out of the centre, but LS11's entry price hasn't caught up. Yorkshire and the Humber's regional average gross yield sits around 6.5% (regional buy-to-let lending data, 2025), so LS11 isn't a fluke, but it is towards the top of what the region genuinely offers rather than typical of it.

Neighbouring LS9 tells a similar story at a slightly lower pitch: an average price of roughly £145,000 against a comparable rent produces a 7.0% gross yield, according to the same buy-to-let market data. Both postcodes share the same underlying driver, a large stock of two and three-bedroom terraces that never carried the price tag of Leeds's more fashionable inner suburbs, bought by landlords who then let to the same tenant pool of students, hospital staff and young professionals working in the city centre. That's a genuine demand story, not a statistical accident, which is exactly why the yield figure is worth taking seriously even as the rest of this article pulls it apart.

This site has checked headline yield claims against the real numbers before, and most of them shrink once Section 24 and true running costs are applied. The rare exception was Renfrewshire and West Dunbartonshire's genuinely top-ranked Scottish yields, which held up under the same test. LS11 doesn't hold up the same way, for reasons that have nothing to do with the rent it actually collects.

So if you're comparing yield tables across different providers before choosing a postcode, treat the headline percentage as a starting point for due diligence, not a number you can bank on until you've checked the price and rent on a specific street.

What buying at LS11's price actually costs

At 75% loan-to-value, an LS11 purchase at £138,500 needs a £34,625 deposit against a £103,875 loan. Current buy-to-let mortgage rates at that LTV sit around 5.49% on a two-year fix (comparison-site data, September 2026), part of the same swap-rate-driven repricing that has pushed residential fixed rates up this week too, ahead of the Bank of England's 17 September decision. On top of the deposit, Leeds sits in England, so Stamp Duty Land Tax applies: standard bands of 0% up to £125,000 and 2% from £125,000 to £250,000, plus a 5% surcharge on the entire price for any additional residential property, raised from 3% on 31 October 2024. On this purchase, that's £270 in standard duty plus £6,925 in surcharge, a total of £7,195 due on completion.

The monthly mortgage interest on that loan comes to roughly £475. Against rent of £854, that's a rent-to-interest ratio of around 180%, comfortably above the 125% (basic-rate) or 145% (higher-rate) cover most lenders require before they'll approve a buy-to-let mortgage.

So passing your lender's affordability test tells you almost nothing about whether the property will actually make you money after tax and real running costs, which is exactly the gap the next two sections close.

The cash flow, before tax

Strip out a 12% management fee (£102 a month), landlord buildings insurance of roughly £26 a month (ABI Premium Tracker-style estimate, 2026), a 10% maintenance reserve (£85 a month) and a one-month annual void allowance (£71 a month), and the rent of £854 a month leaves a net operating income of roughly £570 a month before the mortgage. Deduct the £475 monthly interest payment and this LS11 purchase clears roughly £95 a month before tax, working out at a net yield of around 4.9%, well below the 7.4% gross figure advertised.

So even before tax enters the picture, this is a thin margin: one missed month's rent, one unplanned repair, or a further quarter-point rate rise erases it entirely.

Section 24 turns that margin into a loss for higher-rate taxpayers

Because mortgage interest can no longer be deducted as a business expense, a landlord pays income tax on rental profit calculated before interest relief, then claims a 20% credit against the interest actually paid, a rule this site has tracked in detail since it first hit Manchester buy-to-let purchases under Section 24. On this LS11 property, annual mortgage interest of roughly £5,700 earns a tax credit of roughly £1,140, set against a profit before interest relief of roughly £6,840 a year. A basic-rate (20%) taxpayer pays around £228 a year in tax on that profit and keeps a cash flow of roughly £76 a month. A higher-rate (40%) taxpayer pays around £1,596 a year in tax on the identical profit, enough to flip the £95-a-month pre-tax surplus into a loss of roughly £38 a month.

So if you pay tax at the higher rate, this specific purchase is already losing money each month purely because of how Section 24 taxes rental profit, before a single pound is spent on the property itself.

The EPC bill Leeds's older terraces can't avoid

Every privately rented home in England and Wales needs an EPC rating of C or above by 1 October 2030, covering existing tenancies as well as new ones, under the Warm Homes Plan published 21 January 2026 (subject to final legislation). The cost is capped at £10,000 per property, but the English Housing Survey 2023-24 puts the real average cost of reaching band C at £6,864 across all homes, rising to £10,788 for homes built before 1919. Leeds has a substantial stock of Victorian and Edwardian terraces in postcodes exactly like LS11, precisely the kind of property likely to need spending at or near the cap, a pattern this site also found when it checked the EPC cost facing North East landlords with similar older housing stock. Spreading £10,000 over the roughly four years left before the 2030 deadline works out at around £204 a month.

Add that reserve to the after-tax cash flow above and the basic-rate taxpayer's £76 a month becomes a loss of roughly £128 a month. The higher-rate taxpayer's existing £38-a-month loss deepens to roughly £242 a month.

So the 7.4% yield table never accounted for the biggest single bill most Leeds landlords with older stock will face this decade, and once it's in the numbers, both basic-rate and higher-rate taxpayers are paying to hold this property rather than earning from it.

What this means for you

The maths points toward LS11's marketed 7.4% being a genuine, well-supported number on rent and price, but not a genuine 7.4% return once you own the mortgage, the tax bill and the EPC clock. If you're a higher-rate taxpayer, this specific purchase already loses roughly £242 a month once every real cost is counted, and no amount of future capital growth changes that monthly reality today. Most investors who run this calculation end up doing one of three things: buying only stock that's already rated EPC C or above, which removes the £204-a-month reserve entirely; structuring the purchase through a limited company, where Section 24's interest restriction doesn't apply; or accepting the modest basic-rate margin on offer and treating any capital growth as the genuine return, rather than the monthly rent.

Frankly, if you're weighing LS11 or LS9 against a lower-yielding but already-compliant property elsewhere in Leeds, run both scenarios through an EPC-adjusted yield calculation before you commit, because the postcode with the better headline number isn't the one that will show up in your bank account each month. A property already rated C removes the single biggest swing factor in this whole calculation at a stroke, which is worth more to most portfolios over the next four years than an extra point of gross yield on paper. That's also the same lesson this site keeps finding whenever it tests a marketed yield against Section 24 and real running costs: the number that survives contact with your tax return is rarely the number in the listing.
