First-time buyer in Cardiff: the step-by-step walkthrough
Quick answer: Buying your first home in Cardiff starts with working out your deposit against real local prices — the city's average house price is £273,000 (ONS, May 2026), and first-time buyers here typically pay around £235,000. You'll need a deposit of at least 5% to get a mortgage, the buying process runs on Welsh Land Transaction Tax rather than English stamp duty (and Wales gives first-time buyers no tax relief at all — a genuine difference from England), and a handful of Welsh-specific schemes can lower the deposit or income bar further. None of this is complicated once you see it laid out — it's mostly a case of knowing which numbers apply in Wales specifically, rather than assuming the England-wide advice you'll find everywhere else applies unchanged.
How much deposit you need at Cardiff prices
Lenders typically ask for a minimum 5% deposit, with better rates generally available from 10% and again from 15–25%. Here's what that looks like against Cardiff's verified average house price of £273,000 (ONS UK House Price Index, May 2026, provisional):
| Deposit % | Deposit needed | Mortgage needed |
|---|---|---|
| 5% | £13,650 | £259,350 |
| 10% | £27,300 | £245,700 |
| 15% | £40,950 | £232,050 |
Two things worth knowing alongside that table. First, £273,000 is a city-wide average across all property types — a flat in Cardiff typically sells for around £162,000 and a semi-detached home around £325,000 (ONS, May 2026), so your actual deposit target depends heavily on what and where you're buying; see our areas and prices guide for a breakdown. Second, first-time buyers specifically paid an average of £235,000 in Cardiff in the same period (ONS) — a more realistic anchor than the all-buyer average if you're comparing yourself to other first-time buyers rather than the whole market.
The buying process in Wales — LTT, not SDLT, and no FTB relief
If you've read general UK first-time-buyer advice, most of it assumes you're buying in England. Two things are different in Wales:
- You pay Land Transaction Tax (LTT), not Stamp Duty Land Tax (SDLT). Wales set its own property tax in 2018 and it has its own rates and bands, run by the Welsh Revenue Authority rather than HMRC.
- Wales gives first-time buyers no relief at all. In England, first-time buyers pay 0% tax up to £300,000. In Wales, everyone — first-time buyer or not — pays the same LTT on the same price. Wales's tax-free band is higher than England's standard band (£225,000 versus £125,000), which helps at lower prices, but the lack of first-time-buyer relief means Wales can end up more expensive above roughly £225,000–£300,000. Our LTT vs stamp duty guide has the full rate tables and worked examples if you want the exact numbers for your price point.
Everything else about the process — mortgage offer, solicitor searches, exchange and completion — follows the same broad shape as anywhere else in the UK; it's really just the tax and the local scheme landscape that differ.
Welsh schemes that can help
A handful of Welsh Government schemes exist specifically to reduce the deposit or income barrier for buyers who can't quite reach a full-price purchase on the open market — Help to Buy – Wales (new-build equity loan, though it's due to close to new applications on 30 September 2026), Homebuy – Wales (equity loan for existing homes, mainly in areas with limited affordable supply) and Shared Ownership – Wales (buy a share, rent the rest). Our low-deposit routes guide covers eligibility and how each one actually works, including which ones are still accepting new applicants as of July 2026.
Choosing areas as a first-time buyer
Price is only one filter. Commute time, schools, flood risk and whether a property is leasehold all affect what a given budget actually buys you in Cardiff, and the right area for a first-time buyer often isn't the cheapest one on paper once you factor in resale demand and commute cost. Our areas, prices and commutes guide walks through the main areas first-time buyers tend to consider, from the commuter belt towns to the city's own suburbs.
Getting mortgage-ready before you view
Before you start viewing seriously, it's worth having a rough sense of what you can actually borrow, so you're not falling for houses outside your realistic budget. Most mainstream lenders work from roughly 4.5× your income as a starting multiple, with some willing to stretch to 5–5.5× depending on your deposit, outgoings and circumstances — see our salary needed guide for how that plays out against real Cardiff prices by property type. Two practical steps help here: get an Agreement in Principle from a lender before you view seriously, since estate agents and sellers in a competitive market often expect one, and check your credit file for anything unexpected — a missed payment or an old default you'd forgotten about can affect what's on offer, and it's far better to find that out before you've fallen for a specific house than during the application itself.
Mistakes Cardiff first-time buyers make
- Budgeting off the England-wide stamp duty holiday headlines. Wales runs its own tax system on its own bands — LTT calculators for England will give you the wrong number.
- Assuming first-time buyer relief exists here. It doesn't. Build the full LTT liability into your budget from day one rather than discovering it at your solicitor's completion statement.
- Only checking new-build scheme eligibility once you've fallen for a specific house. Help to Buy – Wales, for instance, only works with participating builders — check the scheme fits before you view, not after you've made an offer.
- Ignoring leasehold and ground rent terms on flats, which are common in Cardiff's city-centre and Bay developments and can affect both mortgageability and resale.
- Treating the average Cardiff price as the target. £273,000 is a city-wide blend of flats, terraces, semis and detached homes that sell for very different amounts — work from the price of the property type you actually want, not the headline average.
FAQ
Do I need a bigger deposit in Wales than in England?
No — deposit requirements come from your mortgage lender, not from Welsh Government rules, so the same 5% minimum generally applies either side of the border. What differs is the tax you pay on top (LTT versus SDLT) and the local schemes available to help with the deposit itself.
Is Help to Buy – Wales still open to new applicants?
Yes, as of July 2026, but applications are due to close on 30 September 2026 — check the current position on gov.wales if you're timing a new-build purchase around it, since scheme deadlines can move.
Can I use a Welsh scheme and a gifted deposit together?
Often, yes — most schemes and gifted deposits aren't mutually exclusive, but each comes with its own conditions, so confirm compatibility with your lender and, where relevant, the scheme provider before assuming they'll combine cleanly.
