I saw a broschure today they are developing Parkvill 3 in Thalang with houses around 2m baht aswell. The house I want to buy cost 4.3m (3 bed rooms and 3 bath rooms) with 60 sqw land. The price differs between the houses depending of the land plot size.
Application form and papers finished today, they said the bank will contact Ead in 1-2 weeks. Just hope for the best.
