What we'll do for you on a new build
Builder contract redlines
Builder contracts favor the builder. We mark up the clauses you should push back on before you sign.
11-month inspection
Your 1-year warranty expires quietly. We book an independent inspection at month 11 — saves $5K+ on average in caught defects.
Verified incentives
We verify the current builder incentives every time we walk a community. Rate buy-downs, design-center credits, closing costs — all itemized.
