First-time buyer in South Wales: the step-by-step walkthrough
Or call 02922 820 840
Quick answer: Buying your first home in South Wales starts with working out your deposit against real local prices — in Cardiff, the average house price is £273,000 (ONS, May 2026), and first-time buyers there typically pay around £235,000. You'll usually 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
Most lenders ask for a deposit of at least 5% of the price. You'll usually get better interest rates with 10%, and better again with 15% to 25%. Here's what that means at Cardiff's average house price of £273,000 (Office for National Statistics, 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 to bear in mind:
- The average mixes every type of home. A flat in Cardiff typically sells for around £162,000 and a semi-detached house for around £325,000 (ONS, May 2026), so your deposit depends on what and where you buy. Our areas and prices guide breaks this down.
- First-time buyers pay less than the average. First-time buyers in Cardiff paid £235,000 on average over the same period, which is a better guide if you're comparing yourself with other first-time buyers.
Buying in Wales: Land Transaction Tax, with no first-time buyer discount
Most first-time buyer advice online assumes you're buying in England. Two things are different in Wales:
- You pay Land Transaction Tax, not stamp duty. Both are taxes you pay when you buy a home. Wales has had its own version since 2018, with its own rates, collected by the Welsh Revenue Authority rather than HMRC.
- There's no first-time buyer discount. In England, first-time buyers pay no stamp duty on the first £300,000. In Wales, everyone pays the same tax on the same price. Wales charges no tax on the first £225,000 (England's starting point for other buyers is £125,000), which helps on cheaper homes. But above roughly £225,000 to £300,000, a first-time buyer can pay more in Wales than in England. Our Land Transaction Tax vs stamp duty guide has the full rates, and the stamp duty Wales calculator works out the figure for your price.
The rest of the process is much the same as anywhere in the UK: the lender's mortgage offer, your solicitor's checks on the property, then exchange of contracts (when the purchase becomes legally binding) and completion (when you get the keys).
Welsh schemes that can help
The Welsh Government runs schemes for people who can't quite afford to buy at full price on the open market:
- Help to Buy – Wales: a Welsh Government loan towards a new-build home, which you pay back as a share of the home's value. Open to applications until 31 March 2027.
- Homebuy – Wales: a similar loan for an existing home, mainly in areas where affordable homes are hard to find.
- Shared Ownership – Wales: you buy part of the home and pay rent on the rest.
Our low-deposit routes guide explains who can apply and how each one works, including which were still taking new applications in July 2026.
Choosing an area
Price is only part of it. Commute time, schools, flood risk and whether a home is leasehold (you own it for a set number of years, but not the land it stands on) all affect what your budget really buys. The cheapest area on paper isn't always the best choice once you add in the cost of commuting and how easy the home would be to sell later. Our areas, prices and commutes guide covers the areas first-time buyers tend to look at, from the commuter towns to Cardiff's own suburbs.
Getting mortgage-ready before you view
Before you start viewing, get a rough idea of what you can borrow, so you don't fall for homes outside your budget. Most mainstream lenders start at about 4.5 times your income, and some go up to 5 or 5.5 times, depending on your deposit, your outgoings and your circumstances. Our salary needed guide shows what that means for different types of home in Cardiff.
Two things help:
- Get an Agreement in Principle. This is a lender's written estimate of how much it might lend you, based on your income and a look at your credit file. Estate agents and sellers often expect to see one before they take your offer seriously.
- Check your credit file. This is the record of how you've handled credit, such as loans, cards and bills. A missed payment or an old default you'd forgotten about can affect what lenders offer, and it's far better to find it now than in the middle of your application.
Mistakes first-time buyers in South Wales make
- Using an England stamp duty calculator. Wales has its own tax with its own rates, so an England calculator gives the wrong figure.
- Expecting a first-time buyer discount. There isn't one in Wales. Include the full Land Transaction Tax in your budget from the start, rather than finding out from your solicitor's final bill.
- Checking Help to Buy – Wales too late. It only works with builders who take part, so check the scheme fits before you view, not after you've made an offer.
- Ignoring the lease on a flat. Many flats in Cardiff city centre and Cardiff Bay are leasehold, with ground rent (a yearly charge to the owner of the land) and other terms that can affect whether lenders will lend on them and how easy they are to sell.
- Aiming for the average price. Cardiff's £273,000 average mixes flats, terraces, semis and detached homes that sell for very different amounts. Work from the price of the type of home you actually want.
FAQ
Do I need a bigger deposit in Wales than in England?
No. Your lender sets the deposit, not the Welsh Government, so the same 5% minimum generally applies on both sides of the border. What's different is the tax you pay on top, and the Welsh schemes that can help with the deposit itself.
Is Help to Buy – Wales still open to new applicants?
Yes. Applications must be in by 31 March 2027 (the deadline was moved from 30 September 2026). Check the latest on gov.wales if you're timing a new-build purchase around it, as deadlines can change.
Can I use a Welsh scheme and a gifted deposit together?
Often, yes. A gifted deposit is money a family member gives you towards your deposit. Most schemes allow one, but each has its own conditions, so check with your lender and, where relevant, the scheme provider before relying on both.
Figures checked against the ONS UK House Price Index and gov.wales in July 2026; the Help to Buy – Wales deadline re-checked October 2026. House prices, tax rates and scheme availability all change over time — confirm current figures before making a purchase decision. This guide is general information, not a personal recommendation.
