Many buy-to-let mistakes happen before any viewing, when an area is chosen on a hunch or one impressive yield figure and the numbers are then made to fit.
A better approach is to shortlist a few areas and compare them on the same measures, using free official sources you can check. This guide shows where to find them, what each can and cannot tell you, and how to pull them into a like-for-like comparison.
It is general information, not financial advice. Data is revised and local rules change, so always check the latest version of each source before you commit.
Start with what the property needs to do
Before comparing areas, be clear about your own constraints. They will rule some places out before the data does.
- Budget. Your total budget includes purchase tax, legal fees and a reserve, not just the price.
- The kind of home you plan to let. A one-bedroom flat, a family house and a shared house each have different running costs and, in some cases, different licensing rules.
- How you will manage it. If you plan to self-manage, distance from where you live matters. If you will use an agent, their fees belong in your sums.
Then choose three or four areas to compare: enough to measure against, few enough to research properly.
1. House prices: use sold prices, not asking prices
HM Land Registry Price Paid Data records residential sales in England and Wales. It is updated on the 20th working day of each month. The most recent two months are incomplete, because registrations can lag completion by anything from two weeks to two months (gov.uk).
Use a typical (median) price for the property type you want in each postcode district or sector, compare like with like, and use a long enough period to smooth out one-off sales.
For a wider trend, the UK House Price Index is published monthly by HM Land Registry with the ONS and others. Recent months are revised, so treat the newest figure as provisional.
2. Rents: combine official averages with local evidence
The ONS publishes average private rents in its Private rent and house prices bulletin. Local figures are available at local authority level. The latest release when this guide was checked was 21 October 2026, with the next due on 18 November 2026.
For context, the October 2026 release gave these averages:
| Nation | Average monthly private rent (September 2026) | Average house price (August 2026) |
|---|---|---|
| UK | £1,406 | £273,000 |
| England | £1,466 | £294,000 |
| Wales | £848 | £216,000 |
| Scotland | £1,011 | £198,000 |
National averages are a sense check, not a target. Add local evidence: comparable properties currently advertised and, where you can, conversations with local letting agents about what lets and how quickly.
3. Gross yield: a like-for-like check for each area
Once you have a typical price and a typical rent for each area, work out a gross yield for each one:
Gross yield (%) = typical annual rent ÷ typical price × 100
Illustrative example only. These are made-up numbers to show the method, not data for any real place.
| Area A | Area B | |
|---|---|---|
| Typical price | £180,000 | £260,000 |
| Typical rent | £950 a month (£11,400 a year) | £1,250 a month (£15,000 a year) |
| Gross yield | £11,400 ÷ £180,000 = 6.3% | £15,000 ÷ £260,000 = 5.8% |
Purchase tax widens the gap. Using the Stamp Duty higher rates for additional dwellings in England:
- Area A: 5% × £125,000 + 7% × £55,000 = £6,250 + £3,850 = £10,100
- Area B: 5% × £125,000 + 7% × £125,000 + 10% × £10,000 = £6,250 + £8,750 + £1,000 = £16,000
Scotland and Wales work differently. Scotland adds an 8% Additional Dwelling Supplement on the whole price on top of LBTT, and Wales has its own Land Transaction Tax higher rates. If you are comparing areas across a border, run the purchase tax for each nation separately.
Higher gross yield is not automatically better: it can reflect higher running costs, more turnover or weaker demand. For net yield, mortgage costs and tax, see our guide on how to calculate buy-to-let rental yield.
4. Crime: useful, with caveats
data.police.uk publishes street-level crime data for the 43 forces in England and Wales, plus British Transport Police and the Police Service of Northern Ireland. It is updated monthly.
Two caveats matter when you use it:
- Locations are anonymised. Each crime is placed on a nearby map point (a street centre or public place) rather than an exact address, and the date is given to the month only. So it is better suited to comparing counts across an area, or within a radius, over several months than to judging a single street.
- It does not cover Scotland. For Scottish areas, use the Scottish Government's Recorded crime in Scotland statistics.
Compare the same period and the same radius for each area, and look at trends rather than one month.
5. Schools: go to the source
Schools can matter if you are letting a family home. In England there is no national catchment dataset. Catchment areas are set by each admissions authority, so check with the local council. For inspection outcomes, read the reports through Ofsted, which also publishes monthly management information on gov.uk.
In Scotland, use school inspection reports from HM Inspectorate of Education. In Wales, use My Local School and Estyn reports. In all three nations, catchments come from the local council.
6. Licensing and local rules
Licensing can change both your costs and what you can let, and it varies by council. There is no single national list of licensing schemes in England, so find the local council for each area and read its private housing licensing pages.
What to look for in England:
- Mandatory HMO licensing applies to properties let to five or more people from two or more households (gov.uk HMO guidance).
- Additional licensing lets a council require licences for smaller HMOs in designated areas.
- Selective licensing lets a council license all private lets in a designated area. Since 23 December 2024, councils have not needed Secretary of State approval for schemes of any size, so check for new or proposed schemes as well as current ones.
Since 1 May 2026, the maximum civil penalty for licensing offences in England is £40,000.
Scotland and Wales have national registration schemes with set fees, so budget for them if you are comparing areas there.
Scotland. Landlords must register with the council, and registration lasts three years. The Scottish Landlord Register charges a principal fee of £85 per applicant and £20 per property. If you apply online to two or more councils, the principal fee is £42.50 per council. A late application fee of £170 applies if you do not renew before expiry, or register only after two requests from the council. Fees rise each 1 April in line with CPI.
Wales. Landlords must register with Rent Smart Wales, and anyone who lets or manages their own property needs a licence, which requires training. Both last five years. Under the fee policy in force from 1 April 2025:
| Rent Smart Wales | Online | Paper |
|---|---|---|
| Landlord registration | £60 | £102 |
| Landlord licence (self-managing) | £254 | £327 |
Rent Smart Wales licence training for landlords costs £35 online or £100 in a classroom. Other authorised training providers may charge different fees.
Fees can change, so check the official page before you budget.
7. Energy efficiency of the local housing stock
Private lets in England and Wales currently need at least an EPC rating of E. The government has confirmed a planned move to EPC C or equivalent from 1 October 2030, with a cost cap of £10,000 per property. This is not yet law: the regulations still need Parliamentary approval.
If an area is dominated by older, harder-to-insulate homes, allow for possible upgrade costs, and check the EPC of any property you consider.
8. Transport, amenities and demand: your own research
There is no single official dataset that rates transport links, local amenities or tenant demand. This is where your own legwork counts:
- Visit each area at different times of day and on different days of the week.
- Note journey times to the places tenants are likely to travel to.
- Look at how long similar properties stay on the rental market.
- Write down where each judgement came from, so you can revisit it later.
Score each area on the same scale, and note the source next to each score.
Pulling it together
A simple comparison table works well:
- List your three or four areas across the top.
- Add rows for typical price, typical rent, gross yield, purchase tax, crime trend, schools, licensing, EPC profile, transport, amenities and demand.
- Score the judgement-based rows on a consistent scale, such as 1 to 5.
- Decide in advance how much each factor matters to you, and weight the scores.
- Rank the areas against each other.
The result is a relative ranking for your goals, not an objective rating of a place. Its value is that every area faces the same questions. Once you have chosen an area and a property, our tenant screening checklist covers finding a tenant in England.
Using the data in anything you share
Most of these sources use the Open Government Licence v3.0, so credit them if you share your comparison. Price Paid Data restricts address use, so share aggregated figures, not addresses.
FAQ
What is the most important factor when comparing buy-to-let areas?
It depends on your goals, but rent you can evidence and a realistic total purchase cost come first. Everything else helps you judge whether that rent is likely to hold.
How do I find average rents for a specific town?
The ONS publishes private rent averages at local authority level in its private rent and house prices bulletin. Combine that with comparable lets currently advertised in the streets you are looking at.
Is police.uk crime data accurate to the street?
Not exactly. Locations are moved to nearby anonymous map points and dates are given by month, so it is best for comparing areas or a radius over time, not a single address.
How do I know if an area has selective licensing?
Check the local council's private housing or licensing pages. There is no single national list in England, and councils can now introduce schemes without Secretary of State approval.
Compare your shortlist on one page
The Ashlar Ledger Area Comparison template puts up to four areas side by side on one A4 page. You enter a typical price and rent for each, it works out gross yield, and you add your own scores for crime, schools, transport, amenities and demand, each with a note of its source. A weighted score then ranks the areas against each other.
It is also part of the Landlord Starter Kit bundle, with the yield calculator and the tenant screening pack. View the Area Comparison template
