We've previously sold in August, September (twice), October (twice), March and May. However, the current market is very weird, so not sure the usual advice of Sept/Spring applies. Where we are (West Sussex) the only properties going sstc are the reasonably priced/unique ones.
We put our last house (rural Wales) on the market in November 2023 on the advice of our EA who suggested it wouldn't hurt (our original plan was to wait till early Spring 2024). Knowing it was a niche property that might take a while to sell, we took a punt.
We'd spent lots on renovating the property from a repossessed tip that had previously taken years to sell and hoped to make sufficient profit to enable us to return 'home' to southern England. Some of the EA valuations were wildly over/under priced imo, so we went for the middle ground.
We had zero viewings between November and January.
First viewings (late Jan) were from non-proceedable 'buyers' who more or less admitted to our EA they were being nosey.
First serious viewings were in early March and we accepted an offer (25k under asking price - so 400k which gave us a very decent profit) in early May from someone who'd first viewed in March.....
Tdlr: I don't actually think it would hurt to market now if you price realistically.
