Should You Sell Your House at Auction in This Market (South Wales)?

I get asked this question a lot – “Mark, should I sell my house at auction right now?”

The truth is, it depends on your situation, your property, and how quickly you need to sell.

I’ve been buying and selling property in South Wales for over 20 years, and I’ve seen the auction market go through highs and lows. Right now, we’re in a bit of a mixed market. Interest rates are higher than they’ve been for a long time, mortgage affordability is tight, and buyers are being more cautious. That means the auction room isn’t quite as lively as it was during the property boom – but that’s not necessarily a bad thing for the right seller.

If you need a fast sale, a property auction can still be one of the quickest routes here in South Wales. If the auction completes and the reserve is reached, the buyer is legally committed, and you can usually complete within 28 days. This is ideal if:

• Your property needs a lot of work and may not appeal to standard mortgage buyers.
  
• You’ve inherited a property and don’t want a long sales process.
  
• You’re facing financial pressure and need certainty.
  
• You have a unique property that might create competitive bidding.
  

Example: Just last month, I helped a seller in Newport who had a terraced house with serious damp problems. It was unmortgageable, but at auction, it still attracted three investors. The seller had their cash in the bank less than a month later.

💡 Tip: If your house has major issues, don’t spend thousands fixing it before sale – investors often prefer to do the work themselves and will factor that into their bid.

The biggest risk with auctions is not getting the price you hoped for, or for the property not to meet the reserve price. In this market, there are fewer investors than in previous years, and those that are bidding are looking for bargains. If two or three keen bidders turn up, you might do well – but if they don’t, your property could sell for less than you expected. Or not at all, rendering it difficult to then sell with an estate agent.

Also, remember that once the hammer falls, you can’t back out without serious penalties. You have to be ready to sell for the final bid price.

Example: Earlier this year in Cardiff, a three-bedroom semi in decent condition went under the hammer with a low guide price to attract interest. Unfortunately, only one serious bidder turned up. The seller got a quick sale, but £12,000 less than the estate agent’s valuation.

💡 Tip: Always set a realistic reserve price – low enough to attract bidders, but high enough to protect yourself from underselling.

At the moment, I’m seeing:

• More distressed sales coming to auction – repossessions, probate properties, and houses in need of renovation.
  
• Investors are being choosy – they’ll buy if the numbers work, but they won’t overpay.
  
• Some sellers are achieving excellent results for rare or high-demand properties, but ordinary homes in average condition often sell for less than on the open market.
  

Example: In the Valleys, I’ve noticed run-down former miners’ cottages still doing well at auction if they’re in villages with strong rental demand. Investors from outside the area see them as good long-term buy-to-lets.

💡 Tip: Speak to local auctioneers to see what’s been selling well recently – each South Wales town can have a very different auction climate.

If interest rates come down, confidence will grow and we may see more competitive bidding at auctions again. Until then, the auction market will remain buyer-friendly. That’s great if you’re buying – but if you’re selling, you need to be realistic.

I expect we’ll see more renovation projects hitting the auction rooms in the next year, particularly in areas like Merthyr Tydfil and Ebbw Vale where sellers often prefer a quick, no-fuss sale.

💡 Tip: If you can hold off selling for 6–12 months and the market improves, you might achieve a better auction price – but weigh that against your need for speed and certainty.

If speed and certainty are your top priorities, auction can still be a great option. But if your goal is to get the absolute highest price, you might be better off with a private sale – even if it takes longer.

Before you decide, I always recommend:

1. Getting a free auction valuation and comparing it with an estate agent’s valuation.
   
2. Talking to someone who understands both markets – like myself – so you can weigh up the pros and cons for your specific property.
   
3. Thinking about your timeframe and financial position.
   

If you’d like my honest opinion on whether an auction is right for your property, I’m always happy to take a look and share my thoughts based on today’s market – no jargon, just straight advice.

💡 Tip: Knowledge is your best tool – the more you understand the current South Wales auction scene, the better your decision will be.
