i have had extensive dealings with this guy. in my opinion and with the benefit of hind sight, i would not deal with him.
he is only interested in money, hey so we all want to make it, and thats why we want to invest here in DR. ...but this guy is not interested in any kind of problems you encounter after you have paid him his money. i have seen him slap his hand together and wipe the air away in front of his face in a single gesture, while saying that its not his problem any more.
he uses his own lawyer, lupo, from santo domingo, a 4 hour drive, and offers to do most legal work within the buying process for free, but the contracts i have seen have been legalised by this guy, with different dates at the bottom of the page, even though they were all signed on the same day.
my personal advice.... be careful...
