1) to save money
2) to have your dream house (design/floor plan etc not available from mass

If your goal is to save money, then: KNOWLEDGE IS MONEY. You have to work
hard to gain the necsssary knowledge and spend a lot of time before, during
and after the construction.
If your goal is 2), then much simpler. Just call around and get quotes from
