I have my own house in Aruba, which is not build by Better Homes.
I have a friend with me now that is looking to buy and seriously considering buying from Better Homes.
We went to a friend's house here that is build by them, and it looks very nice and they have had no problem. The got the house build on time and to a very good price.
Their whole street is build by Better Homes, and they told that it was about 50/50 when it comes to peoples experience with BH.
So like Retagger pointed out, if you just buy on standard terms, you are probably likely to be in a coinflip situation when it comes to result, but like always you should make sure the contract is tight.
