I don't have any hidden gem.
I scout in the market and look if there are some actual gems that I've missed. For the project you've mentioned, I've seen them very active in marketing not only in the forum
But also in social medias, I won't get in during the sale, I'll wait until they're open to the market.
Your decision seems to be a smart move, considering the fact that we can't be certain about a project until they commence the project development. Jumping into a project too early could be disastrous because we tend to have many new projects abandoned by their developer.
Must have steps and choices in making decisions, so that we don't get stuck in projects that don't have a movement in the future, many project developers don't think about future developments, they only focus on the near year and take advantage of investors to make big profits, if the ability to recognize projects that we do not have, it is difficult to develop, especially today many new projects appear simultaneously.
