Are you considering moving home in Southampton over the next 6 to 12 months? You may be a Southampton landlord deciding whether to grow your portfolio or sell off a few properties. Or you’re a Southampton first-time buyer wondering if 2025 is the right time to move.
Understanding whether the current property market favours buyers or sellers is key to making the right call.
If you follow my regular Southampton property updates, you’ll know one of the most reliable ways to assess the market is by looking at the percentage of homes marked as “Sold STC” or “Under Offer” compared to the total number of properties on the market.
Let’s show that in practice. For example, if say there are 500 properties on the market in a location, and 200 are under offer or Sold STC then 200 as a percentage of 500, gives us a sales percentage of 40%. It is this percentage that strongly indicates the local property market temperature and who holds the upper hand, i.e. buyers or sellers (or somewhere in between).
This percentage figure acts as a barometer for market conditions and can be analysed using this table:
- Extreme Buyers’ Market (0%-20%)
- Buyers’ Market (21%-29%)
- Balanced Market (30%-40%)
- Sellers’ Market (41%-49%)
- Hot Sellers’ Market (50%-59%)
- Extreme Sellers’ Market (60%+)
How Does Southampton Compare?
Looking at historical data from the website, The Advisory, which has tracked this metric for years, we can observe some key trends for each May since 2018. (For this exercise, Southampton is SO14-SO19).
- In the years before the pandemic, in Southampton’s market, the percentage figure was 52% in May 2018 and 45% in 2019 (2019 was a tough year for the property market as we were in Brexit negotiations).
- May 2020 was the mid-point in the first lockdown, the percentage dropped, as expected, to 20%.
- Demand rebounded sharply post-pandemic after the end of lockdown, and a year later, in May 2021, the percentage had risen to 65%.
- In May 2022, we were at 72%.
- However, with the fallout of the Liz Truss and Kwasi Kwarteng budget in late 2022 and increasing interest rates, by May 2023 it had settled to longer-term average levels of 55%. May 2024 saw similar levels at 52%.
- Now, we are in May 2025; we see the figure sitting at 47%.
These percentage figures are an average of the Southampton postcodes (as noted above).
For interest, if I break the May 2025 figure into the individual Southampton postcodes, it does actually tell an even more interesting story…
- SO14 – 30%
- SO15 – 47%
- SO16 – 47%
- SO17 – 47%
- SO18 – 55%
- SO19 – 57%
Look at the difference between the postcodes!
Implications for the Southampton Property Market in Mid-2025
So, what does a 47% “Sold STC to total stock” ratio for Southampton as a whole tell us?
It firmly places the Southampton market in a sellers’ market, meaning sellers hold a slightly more dominant position and buyers must bring their A-game.
For Southampton Sellers:
We are now in a market where patience, presentation, and precise pricing are not optional but essential. With buyers enjoying more choice, it’s no longer enough to simply list your property and wait. The standout homes are the ones that are priced right from day one, have strong photography, floor plans, virtual tours, and are marketed properly both online and offline.
If you overprice your Southampton home, expect it to linger on the market. And when a property lingers, price reductions follow, confidence drops, and you lose leverage in negotiations, often resulting in lower offers and a higher chance of fall-throughs before exchange. Getting it right from the start is more important than ever.
That said, the May 2025 interest rate cut brings a welcome tailwind. With the Bank of England shaving 0.25% off the base rate, mortgage rates are easing, and confidence is gradually returning to the buyer pool.
Here’s why that matters:
- First-time buyers in Southampton now face lower monthly mortgage payments, which could help more of them step onto the ladder. That brings fresh energy into the market and supports a healthy chain from the bottom to the top.
- Home movers may use better fixed-rate deals to upsize or remortgage, releasing more stock and unlocking stalled chains.
- Buy-to-let investors, especially those operating in high-yield areas of Southampton, may find the numbers starting to stack up again, particularly with net rental yields improving as borrowing costs fall.
- Buyer confidence is getting a boost. Rate cuts send a signal. They show the Bank wants to support stability and growth. That kind of message can turn ‘wait-and-see’ buyers into ‘let’s book a viewing’ buyers.
- This recent interest rate cut is not a one-off. It’s part of a series of interest rate reductions that began in late 2024. If the trend continues, momentum could build into summer and autumn. Mortgage lenders are already adjusting, with some two-year fixed-rate deals expected to dip nicely below 3.5% and five-year fixed-rate deals not far behind, before the end of the year.
For Southampton Buyers:
This property market is more measured compared to the frenzied pace of 2021 and 2022. There’s room to breathe, to think, and in some cases, to negotiate. That doesn’t mean you can take forever or submit lowball offers on the best homes. Desirable properties are still attracting multiple viewers, but it does mean there are opportunities, particularly for those willing to look beyond the most in-demand streets.
Crucially, get your mortgage agreement in principle before you make an offer. It strengthens your hand massively. Sellers want certainty, and being financially ready sets you apart from others.
Also, don’t be afraid to widen your search boundaries. Often, the best value is found just beyond the traditional hotspots.
My Final Thought:
With a new Government settling in and inflation softening, this interest rate cut could help cement the stable period the Southampton property market has experienced in the last 18 months. It’s not boom territory, but it’s not bust either. It’s a continued return to something more balanced, considered, and sustainable.
If you’re thinking of moving in 2025 or just want to discuss your options, I’d love to hear your thoughts. However, if you aren’t planning to move, yet want to share your thoughts on the Southampton property market, please do make comment.
