Flipping LEGO sets isn’t just for hardcore collectors — it’s one of the most consistent ways to make real profit from sealed retail items. In 2025, these five LEGO sets still have strong upside for resellers, especially once they retire and inventory dries up.
Pro tip: You can buy these new on Amazon or Bricklink now, then track their resale value over time on eBay. Many flippers double their money within 12–24 months of retirement.
1. LEGO Star Wars UCS Razor Crest (75331)
Large UCS Star Wars sets like the Razor Crest are legendary in the LEGO flipping world. With Mandalorian hype still strong, this set is a long-term winner. Retired UCS sets often sell for 2x–3x their retail price.
2. LEGO Icons Eiffel Tower (10307)
At nearly 5 feet tall, this is one of the tallest and most visually striking LEGO builds ever. Big Icons sets tend to explode in value after retirement, and demand from architecture and travel fans adds to its upside.
3. LEGO Ideas The Office (21336)
TV-themed LEGO sets are limited runs and often have a cult-like following. This one already sells above retail on some marketplaces — a strong signal for future gains once it retires.
4. LEGO Winter Village Holiday Main Street (10308)
Holiday sets are perfect for annual flipping — prices spike every Q4 when nostalgic demand kicks in. Even modest winter village sets often resell at 1.5x–2x retail just one year post-retirement.
5. LEGO Creator Medieval Castle (31120)
Castle sets are one of the most reliable long-term holds. This Creator 3-in-1 version is affordable, nostalgic, and has cross-theme appeal — perfect for first-time LEGO investors.
