How much deposit do I need in South Wales?

5% deposit products exist, but rates improve materially at 10% and again at 15%. Lower average prices in Newport and the valleys mean a given cash sum goes further here than in Cardiff or Bristol.

Should I use the agent's recommended mortgage adviser?

You are never obliged to, and an offer cannot lawfully be made conditional on it. Compare independently before deciding.

Can I pull out after having an offer accepted?

Yes, up until exchange of contracts, though you will lose anything already spent on searches, survey and legal work.

Buying & selling

Buying your first home in South Wales — the order to do things in

The steps of a first purchase in the order they actually happen, with the South Wales specifics that generic national guides leave out.

1. Work out what you can borrow before you view anything

Lenders typically work to a multiple of income, adjusted for your commitments and the stress-tested payment. Getting a decision in principle first tells you your real budget and makes your offer credible — many South Wales agents will not put an offer to a seller without one.

Bear in mind that the deposit is not the only cash you need. Budget separately for the survey, legal fees, searches, tax if applicable, and moving costs.

2. Understand Land Transaction Tax, not Stamp Duty

Wales does not use Stamp Duty Land Tax. Purchases in Wales are subject to Land Transaction Tax, which has its own bands and thresholds set by the Welsh Government, and no separate first-time-buyer relief of the kind that exists in England. If you are buying in Bristol or across the border, SDLT applies instead — the two are genuinely different, and a national calculator will mislead you.

Check the current bands before you fix your budget, because the tax is payable within 30 days of completion and is not something a lender will advance against.

3. Choose the right survey, not the cheapest

A mortgage valuation is for the lender, not for you — it confirms the property is worth what you are borrowing against, and it will not tell you the roof is failing. For most purchases a Level 2 Homebuyer Report is the sensible middle ground. For anything pre-1900, visibly altered, or of unusual construction, a Level 3 Building Survey is worth the extra.

In the valleys in particular, older solid-wall terraces with later extensions repay a proper survey. The cost of a Level 3 is a fraction of the cost of discovering the problem after completion.

4. Expect a mining search, and read it

Most of the South Wales coalfield requires a coal mining search. Findings are common, and they are not automatically a reason to walk away — but a result that flags a mine entry near the property, or historic subsidence, needs proper explanation and sometimes a further stability report before your lender is comfortable.

Ask your conveyancer to explain the result in plain English rather than forwarding you the PDF.

5. Instruct quickly once your offer is accepted

The first two weeks after an offer is accepted set the pace of the whole transaction. Instruct your conveyancer immediately, complete the identity and anti-money-laundering checks the same week, and get your mortgage application submitted rather than sitting on the decision in principle.

Ten to sixteen weeks to completion is normal. Leasehold flats — most common in Cardiff Bay and the city centre — sit at the longer end because of the management pack.

6. What to have ready before you need it

Having these to hand removes most of the avoidable delay from a first purchase:

Photo ID and two proofs of address
Three months of bank statements and payslips, or two to three years of accounts if self-employed
Evidence of the deposit's source, and a signed letter if any of it is gifted
Your decision in principle
Details of any existing credit commitments

7. Between exchange and completion

Exchange makes the contract binding and fixes the completion date; buildings insurance normally needs to be in place from exchange, not completion. Arrange removals, meter readings and a final inspection of the property in that window, and confirm with your conveyancer exactly when keys will be released on the day — funds usually move in the morning but release times vary with the chain.
