Which Caribbean CBI option is more convenient now?

I’m exploring different citizenship options in the Caribbean as an alternative plan for my family. With the recent increase in St. Lucia’s investment threshold, I’m trying to figure out which CBI option is more convenient now: Grenada, Antigua, St Kitts, or Saint Lucia. I’ve noticed that Dominica’s prices haven’t risen yet. Do you think they might increase soon?

Dominica's investment amount for citizenship by investment under both direct monetary contribution and real estate investment options has been overhauled. The minimum investment sum is USD$200,000.00 and for family
applications comprising up to four members, the investment sum is $250,000.

Every Caribbean country with a CBI program has aligned its prices with the MoA. This now focuses on the country and its passport and the various investment options it offers. It is not a one-size fits all and choosing the right program requires a level of due diligence on behalf of the investor to ensure that the country and the program meet their own needs
