South Wales just has to be one of the most varied and exciting regional property markets for property investors. Property investors in South Wales can choose from city property, suburban property, student property, holiday property together with the cheapest buy to let property anywhere in the entire UK! Here’s our guide to the best areas of South Wales to invest in buy-to-let.

Why Invest in South Wales?

The South Wales region is the biggest part of Wales by far with the biggest property market. Three-quarters of Wales’ population – that’s 2.2 million people – live in South Wales.

Cardiff, Swansea and Newport are the main cities of South Wales. Just to the north, the South Wales Valleys have mainly ex-industrial towns and villages with many cheap property opportunities. Areas like Monmouthshire, Pembrokeshire and Carmarthenshire are more rural.

The counties of South Wales are Blaenau Gwent, Bridgend County, Caerphilly, Cardiff, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Neath & Port Talbot, Newport City, Pembrokeshire, Rhondda Cynon Taff, Swansea, Torfaen and Vale of Glamorgan. You can check which council area applies to any South Wales property, here.

South Wales was once a heavy industrial area but the economy has been transformed in recent years and is based around manufacturing and services. Cardiff has enjoyed one of the strongest economies in the UK in recent years – the economy here has grown faster than London!

South Wales’ low property prices are actually a big advantage, not a disadvantage. They make it an attractive place for businesses to expand and relocate. South Wales good news stories include the National Digital Exploitation Centre which has already put £1 million into the Valleys area, while sports car maker TVR is building a new factory here and INEOS are planning to build a new 4x4 vehicle at Bridgend.

The South Wales economy has been boosted by the removal of tolls on the Severn Bridge in 2017. This article says property prices are rising as a result.Property investors should also keep an eye on plans for the South Wales Metro. This is an exciting scheme to make South Wales public transport some of the best in the world.

There’s a large student accommodation sector in South Wales. In Cardiff, Cardiff University has around 30,600 students, the University of South Wales has around 25,000 students and Cardiff Metropolitan University has 11,500 students. In Swansea, Swansea University has around 21,000 students and the University of Wales Trinity Saint David has around 10,000 students. The University of South Wales has Newport City Campus in Newport.

Rental Demand in South Wales

South Wales overall has good demand for rented property, with different buy to let markets in different areas. In some places, the demand for buy-to-lets is from the local market. In other parts of South Wales, investors could look at holiday lets or student lets.

Buy to let landlords across Wales as a whole can expect to earn £650 a month from an average rental property according to Homelet. Rents rose 5.5% over the last year.

Attractive rents but below UK average property prices mean South Wales can offer good investor yields often well above 5%. Average letting yields in South Wales, according to LiveYield, are as follows: Blaenau Gwent 5.5%. Bridgend County 5.3%. Caerphilly 5%. Cardiff 5.3%. Carmarthenshire 3.6%. Merthyr Tydfil 4.8%.

Property investors should find that student property yields and holiday property yields are much higher of course.

Here’s our guide to property investment in some of the main cities and towns of South Wales.


Population: 357,200
Average House Price: £216,063

Cardiff (Caerdydd) is the capital of Wales and its biggest city by far. It’s growing fast too – official figures say Cardiff will grow by 20% by 2035 as people move from around Wales into Cardiff.

Cardiff has Wales’ strongest economy. The city has a service economy with well-paid jobs in health, education and public administration, financial and business services, ICT, tourism, a growing digital and bioscience sector and a TV, film and media industry too.

Some plans which should grow the Cardiff economy in future include the Cardiff Capital Region City Deal which will invest £1.2 billion in the area, Central Square and Central Quay.

Cardiff’s growing economy means prices and rents here have risen fast in recent years so Cardiff is one of the most expensive places to buy property in South Wales. However, it’s still possible to buy property in Cardiff from £60,000 upwards.

Swansea (Abertawe) is Wales’ second-largest city. Originally a port and heavy industrial city today the main Swansea industries are services such as professional and financial services, tech., communications, life sciences, marine industries, creative industries, health, education and public administration – including the DVLA which employs 6,000.

There’s been some exciting regeneration in Swansea including the Maritime Quarter, Swansea Marina and SA1 Waterfront. In the future, the Swansea Bay City Deal could bring a £1.27 billion investment into Swansea.

As well as the local residential property market Swansea has a student property market and the area also attracts tourists so there is a demand for visitor accommodation. Swansea is one of the few cities to have a beach and the Gower Area of Outstanding Natural Beauty is nearby.

Newport (Casnewydd) is the third-largest city in Wales, having been granted city status in 2002.

Newport was traditionally a heavy industrial town. Today Newport’s main employers are services including Admiral Group, Go Compare and government departments such as the Intellectual Property Office and Office for National Statistics. The Friars Walk retail scheme has helped to regenerate the city centre and the Celtic Manor Resort and new International Convention Centre Wales are attracting more visitors. £1 billion is being invested in a whole new suburb at Glan Llyn.

Newport is a low property price area compared to much of the UK. But this national press report says that the property market in this part of Wales is on the rise thanks to a mini exodus of house buyers from Bristol into Newport.
