Indeed.
And if want to sell without stuff in, that's also why house clearance people exist.
When my father passed, I had to deal with his house. He hadn't lived in it for a few years- he'd been in sheltered accommodation after a stroke- and it wasn't in the best state although it was heated and weather-tight. I was living over 300 miles away and working...... so I visited with my sister, we took a few things we wanted to keep as memories, made sure that computers etc were securely dealt with, then we got a house clearance firm in. Then sold it as was, got a reasonable price although not top of the "market" (well, I got reasonable offers once I got a grip of the local estate agent who was trying to sell under price to mates). Of the 3 similar reasonable offers I had, I went for the family who wanted to move in and renovate, they were cash buyers.
In the light of my recent experience of my "project" in west Wales, I have no doubt in hindsight that that was the best option. Yes, in theory I could have cleared it myself, renovated it and then sold. But doing so would have cost me my job and quite possibly my marriage. It's not always about maximizing sale price, some things are far more important.
Yeah, property priced suitably will sell. It's those properties in areas like West Wales which were bought at above market value during COVID that are not shifting, because sellers expect to sell for more than they bought for- but they are over priced now because (a) there's a glut of similar properties with folks offloading second homes and (b) many of them are really proper remote and need serious renovation- they only fetched what they did because London buyers fleeing the capital had a lot of spare dosh.
The cash buyer who wants a project and buys at a bit below "market value" can overall be a much better deal than waiting ages in a chain which collapses and expenses get repeated for the next set and the "market value" drops in the interim. Or the buyer plays brinkmanship to get the seller to accept a lower offer to avoid collapsing the chain and being back to square one...... and even a "simple" cash sale can take anything up to 6 months to go from offer to completion.
Life is complicated, it's about what one's priorities are. It's not admitting defeat to take the option that works best overall for oneself, there's no One True Way- just what the best (least worst?) option is for a particular time/situation.
