SunRa,
Please forgive my bluntness but looking at your questions, the subsequents to the responses you have received etc., etc., etc. you are not READY to buy land or dwellings down here yet. NOBODY will be able to tell you how much land or buildings will cos YOU because you appear far too unaware of the culture & how things operate down here - hence you will be charged what people can get away with, not the true value!!
PLEASE, do yourself an emense favour & save yourself a LOT of money - come here for a month, look around & get a feel for the country. THEN, armed with SOME information, come back to live for 9 months or a year RENTING property for that period. Find out whether you want to live North, South or East of the country (West is no good for you - no Sea nearby!!). People who come down to buy property without having lived here for a while, who don't have the connections to make rational & objective decisions, who try to get the information solely from a notice board similar to this, rarely last here more than a few years. They go away dejected, very bitter about the country & ALWAYS a lot poorer than when they arrived!!
Just as a point of interest, WHY do you want to buy some land or buildings down here? Do you intend coming to live here or is this purely an investment for you? If you are coming to live here, what are you intending doing for a job? Your writing style doesn't indicate to me that you intend retiring down here - you seem far too young for that, so what is pushing you in this direction??
Honestly, I am NOT trying to be rude to you, nor inconsiderate of your needs for information BUT, I would certainly recommend you learn more about the country before you embark on investing, or coming to LIVE in the country. Try a further holiday down south - try another up north, try a third out Samana way ....... you'll find them all very pleasant but totally different. One may appeal to you more than the others & you need to know which before you even consider buying anything here!!
Good luck with your searches in the archives. We shall know from your questions/responses if you haven't done as suggested earlier - READ THE ARCHIVES - & help will be far less forthcoming if you haven't done your OWN homework!! - Grahame.
