Before you buy
What to know about new construction homes in King County.
Bring your own agent — it costs you nothing
Builder contracts include buyer agent commissions whether or not you use one. Going direct with the builder's sales team means the same commission stays in the builder's pocket while you lose independent representation.
Design center upgrades add up fast
Most new construction base prices are for a stripped-down package. Flooring, countertops, appliances, and finish upgrades at the design center can add $50,000–$200,000+ to your purchase price. Set a firm upgrade budget before your design center appointment.
Builder contract terms are not standard
Builder contracts are written to protect the builder, not the buyer. Inspection rights, earnest money terms, closing timeline flexibility, and warranty coverage vary significantly between builders. Have your agent review the contract before signing.
Construction loan vs. standard financing
Most buyers use a standard mortgage that closes at completion, not a construction loan. Lock timing matters — if rates change significantly during construction, your rate lock strategy affects your final payment.
New community infrastructure timeline
New King County developments often open before surrounding retail, parks, and schools are built. Understand the full community build-out timeline and what amenities will actually be available at your closing date.

Common questions
King County new construction homes FAQ.
- What new construction communities are available in King County?
- RexMont tracks active new construction communities in King County across all major builders. Your agent can compare pricing, lot availability, included features, and builder reputation.
- Can I negotiate price on a new construction home?
- Sometimes. Builders are more negotiable on upgrades, closing cost contributions, and rate buydowns than on base price — especially in the final phases of a community or when inventory is sitting. Your agent knows which builders have room to negotiate.
- Do I need a home inspection on new construction?
- Yes. New construction can have significant defects despite being brand new. A pre-drywall inspection and a final walkthrough inspection are both worth doing — they often uncover issues the builder's crew missed.
