I'm considering upgrading from an RTX 4060 Ti to an RTX 5070 and may buy the card secondhand through a local marketplace. Is purchasing a used GPU generally risky, and what should I check before handing over the money? I'd also like to know whether the performance increase is worthwhile for the price. My system has an Intel Core i5-14400F, so I don't expect the processor to be a major bottleneck.

A used GPU can be a perfectly reasonable purchase, but only if you can verify that it works before paying. Ask to see it running a benchmark or stress test, inspect the fans and connectors, and check for physical damage. A receipt, original box, and transferable warranty are useful extras. An OCCT test would be a good way to check stability and temperatures.
Also consider alternatives instead of focusing only on the 5070. Depending on local pricing, a similarly priced card from another generation or manufacturer could offer better raw performance or more memory. Check several current benchmarks and compare total cost, warranty coverage, and condition before buying.
If you mainly play at 1080p, your 4060 Ti is still capable and the upgrade may not feel dramatic. At 1440p, the extra performance will be more noticeable. Your i5-14400F should pair reasonably well with a 5070 in most games, although CPU limits can still depend on the title, resolution, and refresh rate.
The 5070 is a meaningful upgrade from the 4060 Ti, especially at 1440p or if you want stronger ray tracing and frame-generation features. Whether it’s worth it depends heavily on the asking price. If the used 5070 is only a little cheaper than a new card, the warranty and return policy may be worth paying for.
I’d compare the actual price difference against new options before deciding. A good deal makes the upgrade much easier to justify, but a small performance increase at a high cost probably isn’t compelling.

Exactly—don’t assume a particular model is automatically the best deal. Used pricing varies a lot, so the value depends on what sellers are asking in your area.
