I get the feeling the value of used Bransons depends heavily on the strength of the dealer support, and therefore brand overall, in your local market. In my area (eastern Ontario), there's a successful, long term Branson dealer and people know the brand (even if they've bought something else), and recognize it as a manual rather than electronic workhorse. But I know folks elsewhere, where Branson was never really a thing, who would look at a 4225H as a deprecated model from a no-longer marketed brand (Branson) of a 2nd tier manufacturer (Tym), and discount accordingly.
For what it's worth, I have a Branson 4225h, no cab, about 280 hours, bought 2019. Had backhoe on it. When I bought a miniex and had it delivered earlier this year, the delivery driver asked what I was going to do with the tractor+backhoe, and offered me C$30k for it after briefly looking it over. He upped his offer quickly to C$32k and it was pretty clear his intent would be to fix some stuff I hadn't gotten around to and then resell it, i.e. it was worth more.
We weren't interested in selling the whole tractor (use it for a range of stuff and have a bunch of attachments), just the backhoe attachment itself, which I ended up selling on consignment at the local Branson dealer later this summer. It was bought by a guy who was just acquiring a used(I think) Branson sitting on the dealer's lot, so there is interest in Bransons.
I'm not sure Canadian pricing is fully comparable to U.S. since the price on new equipment is distorted in weird and wacky ways by tariffs in both countries, and that percolates through to the used market too. But C$32k converts to U$23.5k. That's including backhoe, which ended up being sold separately for U$5700 (converted). So there's one datapoint for you - 4225h like yours, 2019, 280 hours, decent but not super shape, up here presumably worth more than U$18k (23.5-5.7), with loader and bucket but no other attachments. How much more, who knows.
