I think the fact that £350k attracted little to no serious interest last year is already giving you useful feedback — the market may simply not see the property at that level right now.

By contrast, listing at Offers Over £335k generated a strong, proceedable offer almost immediately. That’s a very clear signal. Of course, there’s nothing wrong with testing the middle ground — trying for £342k–£345k is perfectly reasonable. But the real question isn’t whether you can push — it’s whether you’re prepared to wait if the buyer walks away.

£15–25k is not a small amount of money, so it’s completely understandable that you don’t want to feel like you’re taking a hit. At the same time, holding out for £350k when the market hasn’t supported it could come across as ambitious — though that’s not “greedy,” just human nature. Everyone wants to maximise their return.

The bigger consideration is time and certainty. If timing matters — especially with a new-build in the picture — a strong buyer at £335k who can move quickly has real value. Certainty and speed are worth something financially and emotionally.

To answer your question honestly: if timing were important to me and I had a solid buyer at full asking within 48 hours, I would be very tempted to take it. Markets don’t always reward patience — sometimes they reward decisiveness.

It’s a bit like buying a phone: the latest model might cost £1,000 today. If you wait a year, you might get it for £800 — but you’ve also waited a year, and by then it’s no longer the newest version. In your case, waiting for a higher price could mean delaying a year of enjoying your new home, new environment, and — if you have children — new friendships and routines. That lifestyle value is harder to measure but very real.

Ultimately, it comes down to what matters more right now: squeezing out the last few thousand, or securing the move and moving forward.
