That is your opinion. We are on our 3rd newly built home and wouldn't do it any other way. We pick the lot we want then design it to our liking. We've never been disappointed and don't have to worry about replacing the roof the air conditioner etc..
Oh and by the way the 2 homes we've sold...one sold in 24 hours and the second during our first open house 6 days after putting it on the market.
