Why is CF24 leading the pack?
There’s no single reason CF24 has surged to the top – it’s a combination of location, lifestyle and long-term opportunity. Let’s break it down.
Prime tenant mix
CF24 includes several of Cardiff’s most in-demand rental neighbourhoods:
- Cathays – the heart of Cardiff’s student scene
- Roath – a trendy area popular with young professionals
- Splott – an up-and-coming spot with affordable stock and strong yields
With over 30,000 students at Cardiff University and thousands more at nearby institutions, the tenant pool is deep and consistent. Graduates often stay on in Cardiff, creating strong crossover into the professional rental market.
High rental demand
In CF24, multiple tenant types converge:
- Students looking for shared HMOs
- Graduates seeking one-beds and studios
- Young professionals moving for jobs in tech, media, and public sector roles
- Families priced out of more central areas
This makes void periods rare – and rent increases easier to implement.
Solid infrastructure and regeneration
CF24 has seen major investment in:
- Cycleways and public transport – making it easy to access the city centre
- High Street upgrades – including shops, cafés, coworking spaces
- New build-to-rent schemes – proving institutional confidence in the area
And with the South Wales Metro expansion underway, connectivity across the city is only set to improve.

What investors need to know in 2026
If you’re buying in Cardiff this year, here are the trends and rules shaping the market.
EPC targets and green upgrades
From 2026 onwards, landlords may need to ensure EPC ratings of C or above for new tenancies – though final legislation is still being debated.
Start planning now to:
- Improve insulation
- Upgrade boilers and heating systems
- Consider solar panels for HMOs
Grants and local support may be available. Our property management team can advise on what improvements offer the best ROI.
HMO licensing in Cardiff
HMO rules in Cardiff are strict – especially in Cathays and Roath. If you’re planning to invest in a 3+ bedroom shared home, you’ll need:
- A full HMO licence from Cardiff Council
- Fire safety upgrades and floor plans
- Clear tenancy documentation
Don’t skip this step – non-compliance can lead to heavy fines.
Mortgage market shift
Mortgage rates have begun to settle in early 2026, with some lenders offering:
- Buy-to-let rates under 5%
- 75% LTV deals for HMOs
- Green mortgage incentives for energy-efficient properties
That said, affordability remains key. Lenders are stress-testing for potential rate increases, so aim for solid rental coverage.
The February advantage: act before the spring rush
February is one of the smartest times of year to buy investment property. Here’s why:
- Less competition from casual buyers
- More motivated sellers after the Christmas and new year break
- Faster completions with quieter conveyancers
Savvy landlords are already locking in their next CF24 opportunity before the market heats up in spring.
By March and April, bidding wars on high-yield properties in Roath and Cathays are common.
