South Lanarkshire 1-bed rents rose 5.6% in the year to September 2025. Greater Glasgow's rose 9.0%. The gap is 3.4 percentage points in a single year — and it sits along the boundary of PA's catchment.

Gov.scot published the figures in the Private Sector Rent Statistics 2010 to 2025 on 25 November 2025. South Lanarkshire's 1-bed mean moved from £536 to £566. Greater Glasgow's moved from £794 to £865. Both are BRMA-level means (Broad Rental Market Areas are the rent geographies the Scottish Government uses, not council areas).

If you let a flat in Hamilton, Motherwell, Bellshill, Uddingston, Blantyre, Bothwell, Cleland or Ferniegair, that gap matters more this year than the headlines do. Not the Edinburgh average. Not the Scotland-wide story. The one quietly widening on your boundary.

The point of this article is not to tell you what to do. Three landlords on three different streets will get three different right answers. The point is to lay out what the gap means, and the three honest options on the table: refinance, sell, or sit.

What the +5.6% vs +9.0% gap actually means

Take the gov.scot numbers at face value. South Lanarkshire 1-bed: £536 in 2024, £566 in 2025 — £30/month more on a fresh letting. Greater Glasgow 1-bed: £794 in 2024, £865 in 2025 — £71/month more. Both moved up. One moved up more than twice as fast.

Run that against a defensible Hamilton 1-bed run-rate of £575 in 2023, the going rate for that stock at the time. The 2025 South Lanarkshire mean now sits just below that at £566. The 2025 Greater Glasgow mean sits £299 above it at £865. Same property type, two BRMA benchmarks, almost £300 of monthly headroom between them.

Two things to caveat before you act on that arithmetic.

First, the BRMA mean is a wide average. The Scottish Government reports it as a mean, not a median. Your specific street, bedroom count and tenant situation will sit somewhere either side. A tidy Bothwell flat above the train station and a 1-bed conversion above a takeaway are not the same property even when both are 1-beds.

Second, this is the mean for a fresh letting in the open market. While your tenant is in place, you are not in that market. The PRT regime caps in-tenancy rent rises at the lower of CPI, market or a prescribed figure under any future Rent Control Zone. A sitting tenant on an older rent is not immediately exposed to the gap. The exposure shows up at three points: when they leave, when you remortgage, and when your lender's valuer benchmarks a refinance.

For context: the Lothian BRMA mean 2-bed rent ran at £1,356 a month, the highest in the country. Greater Glasgow 4-bed rents have grown 104% cumulatively since 2010. South Lanarkshire 1-bed is rising, just less fast than next-door Glasgow.

That is the data. Now the three options.

Three options — refinance, sell, or sit

One disclosure before we walk through them. Property Angels is a letting agent. We earn a recurring management fee on flats that stay let and nothing on a sale. We do not earn referral fees from brokers, solicitors or accountants. Weigh that when you read the recommendation.

Refinance

The BTL refinance pressure is real and present-tense. Fixes taken in 2019-2021 at 2 to 3% are rolling onto products at 4.5 to 6.5% across 2025 and 2026. HSBC's BTL standard variable rate sat at 7.50% from August 2025 and reduced to 7.25% during 2026 (HSBC published rates, as of writing).

Lender stress tests for ICR (interest cover ratio) typically apply a 5.5 to 6% stress rate. They also apply a cover ratio multiplier: 125% for basic-rate taxpayers, 145% for higher-rate. Scotland's 42p band starts at £43,663 in 2025-26; England's 40p starts at £50,270. A Scottish landlord on £45,000 is already in 145% cover-ratio territory. An English landlord on the same salary is still in 125%.

Here is the other bit landlords miss. The lender stress-tests against current market rent for that property type and BRMA. Not the rent on your statement. Your benchmark is the South Lanarkshire mean of £566, unless your broker uses a national lender whose valuer reaches for Greater Glasgow at £865. Either side of that gradient produces a different answer.

Treat this as a working hypothesis, not documented procedure. RICS Red Book comparable selection is judgement-based; brokers working Lanarkshire flag the pattern, and it fits how the ICR maths bites.

Worked example. Hamilton 1-bed, 75% LTV, £100,000 outstanding mortgage. The lender stresses interest at 6% and applies a 145% cover ratio for a higher-rate taxpayer. Required annual rent is £100,000 × 6% × 1.45 = £8,700.

Run that against three comparables a Hamilton landlord could face:

  • 2023 Hamilton run-rate £575/month = £6,900/year. Fails by £1,800.
  • 2025 South Lanarkshire mean £566/month = £6,792/year. Fails by £1,908.
  • 2025 Greater Glasgow mean £865/month = £10,380/year. Clears with £1,680 to spare.

Same flat. Same loan. Three different lender answers depending on which comparable the valuer reaches for. The South Lanarkshire mean has not risen fast enough to clear the test. Greater Glasgow next door has.

That is the maths most landlords don't run until the broker asks. Modelling it is the cheapest thing you can do this week.

Sell

Around 350 landlords a month have been leaving the Scottish Landlord Register since the May 2024 housing emergency declaration. Cumulatively that is 35,591 individual landlords since 2016 (gov.scot FOI 202500486687 plus the Scottish Landlord Register data series). The SAL Portfolio Survey 2025 found 54% of its members plan to shrink their portfolio in the next five years; only 9% plan to expand. The sell question is not unusual to ask.

The numbers a Lanarkshire seller should put on the table before deciding:

  • ADS at 8%. The Additional Dwelling Supplement rose from 6% to 8% on contracts entered on or after 5 December 2024. Sell one Lanarkshire BTL and rebuy another on a £200,000 purchase and you absorb £16,000 in ADS before any other cost. Crucially, you cannot reclaim ADS just because the new flat is your only let. The reclaim mechanism is tied to selling your main residence, not your investment.
  • CGT, worked through. Annual exempt amount is £3,000 from April 2024 (HMRC). Residential rates are 18% inside the basic-rate band and 24% above, from 30 October 2024. Take a £50,000 gross gain — £47,000 after the £3,000 exemption. A basic-rate landlord with £15,000 of basic-rate headroom pays 18% on £15,000 and 24% on £32,000 — about £10,380. A higher-rate landlord pays 24% on the full £47,000 — about £11,280. The gap matters most around the threshold; model your specific income.
  • Mortgage early-repayment charges. Most BTL fixes carry ERCs of 1-5% during the fixed term. A £100,000 mortgage redeemed mid-fix at a 3% ERC is £3,000 the seller cannot dodge.
  • Sale transaction costs. Scottish solicitor-estate-agent fees run 0.75-1.5% plus VAT. Home Report £300-£500. Conveyancing £600-£1,200. On a £150,000 sale that stacks to around £2,500-£4,000.
  • EPC remediation pressure. The Heat Retention Rating reform is paused, but a buyer's solicitor still flags an EPC D or E and offers below asking. Remediation to a C runs £500-£5,000+ on Lanarkshire stock, depending on the start point.
  • Sell with the tenant in situ vs sell vacant. With the tenant in occupation you sell to another landlord, often 10-15% below vacant possession. To sell vacant you serve a Notice to Leave on Ground 1, which takes 84 days. If contested at the First-tier Tribunal Housing and Property Chamber, the wait is materially longer. The Chamber carried 3,988 open cases into 2025-26 (Scottish Tribunals Annual Report 2024-25). The queue is real.

The market is also receiving more rental stock from other landlords doing the same maths. The share of sold Scottish rentals that stayed in the sector rose from 9% in 2024 to 17% in 2025 (SafeDeposits Scotland 2025). The buyer pool is partly other landlords looking at the same conditions you are.

Stack those costs against the gain. ERCs, agent and legal fees, EPC remediation and CGT can absorb £15,000 to £25,000 on a typical Hamilton 1-bed sale. The sell case stands or falls on the size of the gain after fifteen or twenty years of holding. Run the modelling before you list.

Sit (hold with tenant)

Holding is the most common position right now. Tenant stays, rent stays, you ride out the gap and revisit when your fix matures. PA explicitly supports this path alongside stay-and-let and step-back.

The honest cost list against the actual decision:

  • Section 24 drag at higher rate. From April 2027, UK rental income faces a separate "property basic rate" of 22% versus the 20% employment basic rate. Higher and additional rates run 42% and 47%. For a Scottish higher-rate landlord with a mortgaged flat, that 2pp uplift compounds across every year held.
  • Refinance roll-on. Each year held is a year closer to a fix rolling off into a higher rate environment. The South Lanarkshire mean is rising more slowly than Greater Glasgow, so the lender's stress-test benchmark for your catchment lags the comparable next door. The cover-ratio cushion gets harder to clear each cycle, not easier.
  • Rent Control Zone exposure. If your BRMA is designated a Rent Control Zone under the Housing (Scotland) Act 2025, in-tenancy rent rises are capped. The cap is the lower of CPI, market or the prescribed figure. Holding a sitting tenant on an older rent means waiting for them to leave before a market reset.
  • Stock-condition costs. A 1-bed in its twelfth year of letting needs a kitchen update. A 2017-vintage boiler is approaching replacement. The £85 landlord registration fee is the cheap line. The £6,000 kitchen and £2,500 boiler are the lines that come up while you wait.
  • Opportunity cost of capital. Equity locked into a holding rental is equity not earning elsewhere. For a 50-plus landlord with one or two flats, that may matter more than the political weather.

None of these is catastrophic in a single year. In aggregate they explain why "hold and wait" is a real decision with real ongoing drag, not the free option it can feel like.

The honest answer: depends on your situation

There is no portfolio-wide right answer to refinance-vs-sell-vs-hold. Three landlords on the same Hamilton street with the same property type will land in three different positions. Tax band, mortgage status, life stage and time horizon push the answer somewhere different each time.

Before the Health Check, an honest broker's view of the headline patterns.

If your fix rolls off before March 2027 and your current rent sits above the South Lanarkshire mean, refinance leans favourable. Model against both the South Lanarkshire and Greater Glasgow comparables this quarter. The pressure point is whichever benchmark your lender uses.

If you are a higher-rate taxpayer who has held the flat fifteen years or more, the sell case starts looking realistic. The CGT bite is the cost on the table. So is the ERC if your fix is mid-term.

If your fix runs through 2027 and a sitting tenant still passes a 145% ICR test on current rates, hold-and-watch is the least-bad bet. Rent Control Zone designations land in 2027. That is your trigger to revisit.

Those are the headline patterns. The Health Check is the route into the answer for landlords whose situation does not fit one of the three cleanly.

The Health Check is a free 2-minute diagnostic. Eleven questions cover portfolio size, location, property type, management style, rent review history, your biggest current challenge, void periods, and your twelve-month goals. The output is a recommendation specific to your portfolio in current market conditions.

For a Hamilton or Motherwell respondent, the output names the South Lanarkshire vs Greater Glasgow rent-growth gap and what it means for your bedroom count. For a landlord weighing the sell decision, it points at the ADS and CGT modelling. For a landlord facing autumn refinance, it points at the lender-stress-test angle.

The Health Check is the Health Check. Not a sales call. The result lands in your inbox and one of us reads it. If the answer is "you do not need PA to do anything", that is what we tell you.

What we're seeing on the ground

A note in a different register.

This week three Hamilton landlords asked me the same question: refinance now, refinance later, or hold off and see. The three flats are different. One is a 1-bed near the station with a six-year tenant on a 2022 rent. One is a 2-bed in Burnbank with a fix expiring in October. One is a Motherwell let the owner inherited eighteen months ago and has not really looked at since.

The answer is different in each case. The 1-bed near the station sits above the South Lanarkshire mean — whether the lender notices depends on which BRMA the valuer uses. The Burnbank 2-bed has a 5.6% fix on offer and an ICR test that just clears at 6.2%. The Motherwell flat has a deposit prescribed-information problem. Different problem entirely.

What I am not doing is telling all three the same thing. The 3.4-point gap between South Lanarkshire and Greater Glasgow is a real piece of context. Not a single answer for either side of the boundary.

I am watching whether the autumn refinance round shifts that pattern. Three is a small sample. Three could become five by November.

The Health Check

Eleven questions. Two minutes. propertyangels.uk/health-check/.

The output is a personalised position report against current Lanarkshire market data. It uses the gov.scot rent statistics for your bedroom count, plus the cost lines to model before a remortgage or sale. No charge, no follow-up call unless you ask for one.

If you would rather come in and talk in person, we are at 14 Main Street in Bothwell. Most weeks we have time for a half-hour with no obligation. Call first to check we are around.

The point is to do the thinking before the bank does it, and before a buyer offer sets the timeline.

Sources and methodology

Methodology note: BRMA-level mean rent statistics are wide averages across the South Lanarkshire and Greater Glasgow geographies. Worked examples use the gov.scot 2024 → 2025 BRMA means (£536 → £566 South Lanarkshire; £794 → £865 Greater Glasgow), plus a defensible Hamilton 1-bed run-rate of £575 in 2023 for the ICR worked example. The £575 figure is a market practitioner's run-rate, not a published statistic — your own street, property condition and tenant position will sit somewhere either side of all three numbers. The article is general guidance; the Health Check produces a recommendation against your specific portfolio.

Note on the -11.1% / £526 → £468 figure that appears elsewhere in the publication: gov.scot Table 5 (1 Bedroom Shared Properties), p. 20, reports a -11.1% fall in the South Lanarkshire 1-bed shared category. That is the HMO-room-equivalent segment, not self-contained 1-bed flats. The publication itself flags the shared table for small underlying sample sizes in several BRMAs. A typical PA-catchment landlord owns self-contained stock, not rooms in shared accommodation, so the standard 1-bed Table 1 figure is the one this article uses.
