How to use these numbers
- →These are planning ranges, not bids. A builder bid varies with site, finishes, and timing. Use this to know whether you're in the right ballpark before you spend a dollar.
- →Add land separately. Hawaii land prices vary 10x between rural and metro. Budget land independently.
- →Most clients land mid-tier. If you're imagining "modest custom," that's the mid range, not the low one.
- →Carry 10% contingency on top. Already included in our ranges, but worth knowing.
