Lets say you started a blog/website a few months ago and you're at 15 DA, few hundred visits a month, but link buiding has been slow. Then you come across an expired domain in the same exact niche with really great metrics. 40 DA, and before it expired it was getting 10k visits a month. Lets say you buy the expired domain, restore it completely, then operate it as a money site for a3-4 months. You get rankings/traffic back to mostly what it was at before it expired. THEN you do a "rebrand" and 301 the entire site to your previous site (with the DA of 15). The reason you are sticking with your old site is bc of branding and the url is sleek, etc. Is this a white hat enough of a method for your old site to get really strong really quickly once the restored for a few months expired domain is 301'd? I understand that buying an expired and 301'ing it imeediately doesnt work anymore. But if you play this restoration/rebrand game after a few months would that make the 301 effective?
