A wobbly leg, a scuffed heel, a missing remote. The instinct is either to fix everything or fix nothing. Both are usually wrong.
The only formula you need
A repair is worth doing when the increase in realistic sale price is comfortably larger than the cost of the repair plus the value of your time. "Comfortably" matters — if it's close, list it as-is and describe the flaw honestly.
Where fixing usually pays
Cleaning. Almost always. A deep clean costs an afternoon and moves an item from "used" to "cared for", which is a different price bracket entirely.
Missing standard parts. Cables, remotes, shelf pins, cushion covers. Cheap to source, and their absence knocks a disproportionate amount off the price because buyers assume more is wrong than actually is.
Structural stability on furniture. A chair that rocks reads as broken. Tightening it reads as solid.
Where it usually doesn't
Specialist repairs on low-value items, cosmetic refinishing on anything with collector value (originality often beats condition), and anything requiring a part you'd have to wait weeks for. Time on market has a cost too.
Let the numbers decide
In GoSell, the repair ROI view puts the estimated repair cost, the time it takes and the expected value uplift side by side, so the decision stops being a feeling. If you're flipping for profit, it's surfaced by default — because for a flipper, that spread is the entire business.
