Can't get my head around UC project pricing

Visited Land Craft Golflinks and 11th Avenue Gaur City 2 last weekend. I noticed how Land Craft, being completed, makes the total cost of ownership clearer, no hidden PLC surprises. But for 11th Avenue, the UC project, I'm hearing about these 'preferential location charges' that really inflate the final price beyond the advertised rate. It almost feels like a trick. So, is that PLC common for most UC projects, and does it usually eat into your future appreciation? Trying to figure out if the RTM project, despite its higher initial price, actually ends up being cheaper overall compared to a UC one after all these add-ons. Any experienced buyers here with similar findings?
