Renovation content performs well on TikTok and Reels specifically because the format rewards visual transformation - a well-shot demo-to-finished clip can outperform almost any other content type for reach, even from a small account with no existing following.
The realistic bar: you don't need to be a content creator. A simple time-lapse of a real project, filmed on a phone, with a short caption, is enough to work. The mistake to avoid is treating it like paid advertising - the accounts that do well post authentically and consistently, not polished and rarely.
