Three levels of DIY and most people overestimate what they can handle. Level 1: buy a finished unit, handle site prep yourself. You save $3,000 to $8,000 in labor. I recommend this to 90% of people. Level 2: buy a bare shell, finish the interior yourself. Insulation, electrical, plumbing, flooring. You save $5,000 to $12,000 but you need moderate skills and it takes 3-6 months. Level 3: buy a raw container, cut openings, weld, finish everything. Save up to $15,000-$25,000 but you need expert welding and construction. Not for first timers. Biggest mistakes: not checking permits first, cutting structural corners (compromises the frame), no thermal break (condensation and mold), underestimating timeline, budget overruns. Most DIY builds end up costing 80-90% of a factory finished unit after fixing mistakes. At $7,995 to $28,550 delivered and ready, factory finished is usually the better bet.
