Buying a New Construction Home: What's Different from a Resale Purchase

Buying a new construction home differs from a resale in five specific ways: the contract is the builder's proprietary paper (not the state's standard form), inspections come in three phases (not one), a limited warranty replaces the resale's prior-owner disclosure, financing often flows through a builder-preferred lender tied to the incentive package, and contract-to-keys can run 4 to 12 months instead of 30 to 45 days. Everything else — appraisal, title, escrow, homeowners insurance — looks broadly similar.

According to the U.S. Census Bureau's New Residential Sales report, new single-family homes account for roughly 12–15% of all home sales in a typical year — meaningful, but small enough that most buyers walk into a builder's model home without a mental model for how the process is different. The general home-buying checklist covers the shared basics; this article picks up the delta unique to new-builds.

Key Takeaways

• New construction isn't a monolith — production/tract, semi-custom, spec, and custom homes carry different price flexibility and timeline risk. Base-price negotiation is tightest on production and loosest on spec homes near quarter-end.
• The builder's contract is the builder's paper, not the state form. Read (or have an attorney read) the clauses on completion-date float, allowance overages, materials substitution, deposits, and cancellation before signing.
• Get three inspections — pre-pour foundation (optional), pre-drywall (the important one), and a final walkthrough — using ASHI or InterNACHI new-construction standards.
• The 1-2-10 warranty is modeled on the NAHB Model Home Builders' Limited Warranty — but it's a limited warranty. Log punch-list items in writing before Year 1 ends.
• Builder incentives usually require the preferred lender or title company. That's legal under RESPA §8, but shop one outside lender to know the incentive's true value.

New-Build vs. Resale — What Actually Differs

The nice things about a new build: nothing is broken yet, systems are new and under warranty, layout reflects current buyer preferences, and the energy code is current. In some markets, builder incentives beat what a resale seller would concede on price.

What's asymmetric — and what buyers routinely miss:

• No prior-owner disclosure. On a new build, "condition" is defined by the builder's warranty — a limited contract with defined exclusions — not by a seller disclosure form.
• The contract is the builder's paper. Proprietary, 30–80 pages, drafted to protect the builder.
• Financing may run through the builder's lender because the incentive package requires it.
• Inspections are staged in three phases, and the municipal code inspector doesn't work for you.
• The timeline is longer. Contract-to-close on a "to-be-built" home is 4–12 months — plan against the outside date, not the target.

The Four Types of New Construction (and How Price Flexibility Differs)

Production / tract homes have fixed floorplans and materials with dozens to hundreds of copies. You choose lot, elevation, and a limited finish package. Least room on base price, but the most room to stack incentives.

Semi-custom homes offer meaningful customization inside a defined menu — structural options, kitchen layouts, finish tiers. Longer timeline, some negotiation on base plus known-cost upgrades.

Spec homes are production or semi-custom homes the builder started on speculation, typically finished with no buyer attached. Because carrying costs mount every month, spec homes are usually the most negotiable on base price and fastest to close. Timing an offer near quarter-end (March, June, September, December) helps.

Custom homes have your architect, your plans, the builder as general contractor. This guide focuses on the first three categories — custom buyers typically hire an owner's representative to advise them.

The Builder's Contract — Where It Diverges From the State Form

It's the builder's paper. A proprietary document drafted by the builder's counsel, 30–80 pages long. Assume every clause protects the builder unless proven otherwise. Have a real-estate attorney (licensed in your state) read it before you sign.

Completion-date float. Builder contracts routinely give the builder wide latitude — "on or about," "±60 days," "subject to weather and material availability." Ask what remedy you have if the builder slips 30, 60, or 90 days beyond the outside date. Most contracts let you cancel and recover earnest money after a defined slip — but not compensation for temporary housing.

Allowance overages and materials substitution. The base price includes "allowances" for tile, cabinets, fixtures, flooring. Going above the allowance is a change order with builder markup. The contract typically also gives the builder the right to substitute "materials of equal or greater value" if the specified item is unavailable — swapping components without your consent. Ask for a "no substitution without buyer consent" side letter, or a defined dispute process.

Deposits and forfeiture. Earnest money on new construction typically runs 5–10% of purchase price (versus 1–3% on resales) and may be paid in stages. It's usually non-refundable outside a narrow set of contingencies — financing failure, appraisal shortfall (sometimes), builder default. Compare with how earnest money works on a resale — Opendoor's buyer offers, for instance, include a due-diligence period during which a buyer can cancel for any reason and recover earnest money (Opendoor Help Center).

Cancellation and arbitration. Buyer-side cancellation typically forfeits all deposits and upgrade payments to date. Builder-side cancellation (rare) returns your money without further compensation. Mandatory-arbitration clauses are standard and usually preclude class action.

Builder Incentives — What's Actually Valuable and What's Baked Into Price

Builders are reluctant to move published base prices — quarterly reports, comparable-sale integrity, and appraisal comps for other buyers all constrain them. Instead, they offer incentives: closing-cost credits, rate buydowns (temporary or permanent), free upgrades or upgrade credits, and sometimes covered HOA dues.

Two rules for evaluating them:

• Value real dollars, not decorative ones. Permanent rate buydowns and closing-cost credits (which offset what closing costs actually include) are real dollar value. Free "designer packages" you'd never have bought yourself are theater.
• Most incentives require the builder's preferred lender or title. This is legal under RESPA §8 anti-kickback rules as long as the affiliated business is disclosed. The incentive is effectively paid out of the lender's rate/fee stack — compare total cost of the preferred lender (rate + fees, net of incentives) against an outside lender's best offer.

Worked example: a builder offers $15,000 in closing-cost credits at the preferred lender's 6.85% rate. An outside lender quotes 6.60% with lower fees. On a $400,000 loan, the 0.25% rate difference costs ~$65/month, or ~$23,400 over 30 years. Even after the $15,000 incentive, the outside lender wins on total cost. The math flips if rates are closer or the incentive is larger — you don't know until you shop.

Financing — Builder's Lender vs. Shopping Your Own

Get a mortgage preapproval before you walk into a model home. It signals seriousness to the sales team and tells you how much house you can actually afford before you fall in love with a floorplan.

The default — end loan through the builder's preferred lender. Fast, tied to the incentive package, familiar to the closing team. You don't know whether the rate is competitive without a shop.

Outside end-loan lenders. Bring your own preapproval from a bank, credit union, or broker. Most builder contracts accept an outside lender; the incentive package may shrink. Even if you end up back at the preferred lender, an outside quote is your leverage.

Construction-to-perm vs. end loan. On production and semi-custom homes, most buyers use an end loan — you close on the finished home the way you'd close on a resale. On custom homes (and some spec purchases where financing needs to fund construction), a construction-to-permanent (or "one-time close") loan finances the build and converts to a permanent mortgage at completion. For ground-up new construction, look at the FHA One-Time Close Construction-to-Permanent Loan (FHA-CTP) or Fannie Mae's Single-Close Construction-to-Permanent product. FHA 203(k) is for rehabilitation and reconstruction of existing homes — not ground-up new builds — so don't confuse the two.

Inspections — Three Phases, Not One

The municipal code inspector confirms the home meets local code — a floor, not a ceiling, and the code inspector doesn't work for you. Both ASHI and InterNACHI publish new-construction inspection standards recognizing three phases.

Phase 1 — pre-pour foundation (optional). Before the concrete slab or basement pour, an inspector reviews footings, rebar, moisture barrier, and grade. Valuable in expansive-soil regions (Texas, parts of Colorado, coastal Carolinas) and on custom homes. Skippable on production tract homes where the foundation package is well-documented.

Phase 2 — pre-drywall. The single most important inspection. Framing, rough plumbing, rough electrical, HVAC ductwork, insulation, and moisture flashing are all visible before drywall covers them for the next 30–100 years. Schedule this with the builder when framing is complete and mechanicals are roughed in.

Phase 3 — final walkthrough and punch list. Before closing, walk the home with your inspector — not just the builder's superintendent — and generate a written punch list of every item needing correction. A formal home inspection checklist for buyers keeps you systematic. The builder should agree in writing which items are pre-close corrections and which move to Year-1 workmanship coverage.

Budget $400–$900 per inspection. On a $500,000 home, three inspections at $600 each is 0.36% of purchase price for materially better information.

Warranty — the 1-2-10 Framework and What It Excludes

Most production builders offer a limited warranty modeled on the NAHB Model Home Builders' Limited Warranty. The industry shorthand is 1-2-10.

Structural coverage is typically backed by a third-party warranty administrator — 2-10 Home Buyers Warranty, Residential Warranty Company, and StrucSure Home Warranty are the largest — rather than the builder directly. That matters if the builder goes out of business, which happens more often than buyers assume during downturns.

Read the warranty booklet before closing — it's usually 20–40 pages and defines every term. Common exclusions: normal shrinkage cracks under 1/16 inch, cosmetic drift, consumer-product appliance failures (covered by the manufacturer's separate warranty), owner-caused damage, and secondary damage from unresolved punch-list items.

Should You Bring Your Own Agent?

Yes. The builder's on-site sales representative works for the builder — their fiduciary duty runs to the builder, not to you. Your buyer's agent negotiates incentive packages and upgrade credits, reviews the contract before you sign, and manages the punch-list handoff. Their commission is typically paid by the builder as part of the marketing budget.

Important logistic: most builders require the buyer's agent to register on the first visit. If you walk into the model home alone and later bring an agent, the builder can decline to pay the buyer-side commission — which usually ends the agent's ability to represent you.

After Closing — The First 30 Days

Use the new homeowner checklist as your base and layer on new-construction specifics:

• Register the warranty and store the paperwork somewhere you'll find it in five years.
• Log remaining punch-list items in writing within the first week.
• Let the house settle for 60–90 days before final touch-ups. Normal shrinkage is expected and covered separately from workmanship claims.
• Month 11: do a full self-walkthrough and submit a consolidated Year-1 warranty list before coverage closes — the single most-missed step in new-construction ownership.
