New-home sales and builder workflows
Builder tech is not agent tech. This chapter is written for two readers: the buyer's agent who works new construction, and the on-site sales rep at the builder's model home. Read your section, and read the shared middle.
Working the other side of the desk? The builder rep's own operating manual is The New-Home Sales Rep Operating Stack: the OSC playbook, the model home visit, incentives inside the rules, realtor relations and contract to keys, from the builder side.
New construction runs on software the agent never logs into. The builder's CRM, scheduling system, and pricing engine sit behind a sales office wall, and the agent's whole job is done from the outside: registering the buyer correctly, tracking inventory by hand or through an authorized feed, and asking the right questions in the sales office. This chapter separates what the builder side owns from what an agent or rep can actually touch, then gives each reader their own daily procedure.
How the builder side is wired
None of the systems below publish list pricing; all are enterprise, sales-assisted, demo-gated report. That is itself useful information: if a vendor pitches you a self-serve builder data feed at a public price, it is not one of these.
| System | What it is | What the agent will see | What the agent will never see |
|---|---|---|---|
| Lasso CRM (ECI) | Builder-side sales CRM, 500+ builders/developers claim | Nothing directly; the rep's follow-up emails and texts come out of it | Lead scoring, internal pipeline notes, other buyers' data |
| Hyphen BuildPro / SupplyPro / BRIX / HomeFront | Construction scheduling, trade coordination, and back-office ERP claim | Nothing; this is builder-and-trade only | Build schedules, cost data, supplier communication |
| Anewgo | Interactive floor plans, 3D renderings, lot maps, the sales-office kiosk app claim | The public-facing plan browser and virtual tours on the builder's website | The backend lead-journey dashboard the rep sees |
| AtlasRTX (merging under Verse.ai in 2026) | AI chat/SMS assistant answering buyer FAQs on builder sites, e.g. KB Home's "BuilderBot" claim | The public chat widget, if you interact with it as a visitor | The lead-scoring and analytics layer behind it |
| BDX / NewHomeSource, now under Zonda/CoStar (deal closed Aug 21, 2026) | Consumer-facing new-construction listing site, fed by builder XML overnight verified | Public listings, same as any consumer; agents can also reach "New Home Source Professional," a no-cost MLS-branded feed of new-construction inventory for Realtors via 25+ partner MLSs claim | The raw builder feed itself; no public API for individual agents |
Two structural facts worth knowing before you ask a vendor for a shortcut. First, no source in this research found a self-serve, public API or feed that hands quick-move-in inventory data to an individual buyer's agent outside an MLS partnership or a builder-authorized tool report. Second, Lennar's own terms of use are reported to prohibit "automated methods including AI agents... screen and database scraping, spiders, bots, robots, or crawlers" for accessing site content report; treat every builder site the same way even where the exact clause was not independently confirmed. Never point Claude, a script, or any tool at a builder's website to scrape inventory. The legitimate paths are listed in the tracking section below.
Registration and co-op, in plain words
This is the single highest-stakes procedural rule in new-home sales, for both readers.
- The first-visit rule. Standard trade guidance across builders: register the buyer with the builder on the first visit to the model home or sales office, in person, or the agent's ability to be recognized (and paid) on that community can be permanently lost report.
- Pre-register online. Where a builder allows it, register the buyer online or by phone before any site visit, so representation is locked in ahead of a walk-in report.
- Buyer agreement first. Since the NAR settlement (effective August 17, 2024), a written buyer-broker agreement must be signed before touring any home, specifying compensation as a dollar amount or percentage verified. New construction is not exempt. This is also standard operator practice: a working Arizona buyer's agent's procedure runs a six-document signed packet, including the Buyer-Broker Exclusive Employment Agreement, before any showing operator.
- Verify co-op per community, in writing. No builder publishes a public, current, state-specific co-op commission schedule. DR Horton, Taylor Morrison, and Meritage are reported around 2-3% standard; Lennar's is community-variable and must be confirmed each time; time-boxed promotional bumps have appeared in specific markets historically report. Since the NAR settlement moved compensation off the MLS, builders disclose it through their own registration forms, websites, and direct outreach instead report. Ask, and get the answer in writing, at every community, every time; do not assume last quarter's number still applies.
- Keep the registration confirmation. Screenshot or save whatever the sales office gives you (a signed card, an email confirmation, a portal registration record). It is your only proof of representation if the community's co-op position is challenged later.
Quick move-in inventory tracking without scraping
You cannot pull a live feed of a builder's quick-move-in (QMI) homes yourself. You can build an accurate weekly picture by hand from sources that are meant to be used this way.
- The builder's own site, by hand. Visit weekly, note price, incentive, and completion date per home. Never automate this visit; a human reads the page.
- NewHomeSource.com. Builder XML feeds import overnight, so listings are typically no more than a business day stale verified.
- Zillow builder feeds. Builders submit new-construction homes and community data via direct feed or Zillow's "New Home Feed" tool for Promoted Communities placement; a separate "Listing Connect" tool syncs MLS-published new-construction listings verified.
- MLS-partnered New Home Source Professional. A no-cost, MLS-branded feed available to Realtors through 25+ partner MLSs, built specifically to surface new-construction inventory that plan-stage homes (no fixed address or price yet) often miss in a standard MLS search claim.
Weekly manual tracking sheet, one row per home, one sheet per builder or community:
Week of: [date] Builder / Community: | Address or lot # | Plan | Sqft | Price | Incentive (exact terms) | Est. close date | Source | Last checked | |---|---|---|---|---|---|---|---| | | | | | | | | |
What Claude does with this sheet: reads the sheet you paste in, compares it to last week's version, drafts comparison notes and buyer-facing summaries. Claude never fetches a builder site itself, never opens a browser tab to check current inventory, and never treats a number it was not given as verified. If a field is blank, Claude should say so, not estimate.
The walk-in checklist
Generalized from a working Arizona buyer's agent's own written checklist for touring new construction without an agent operator. Whether you are the buyer's agent prepping a client or the on-site rep greeting a walk-in, this is the shape of the conversation that should happen before anyone signs anything.
- Before the door. Confirm the registration rule for this specific community. Bring ID, a rough budget, and an outside pre-approval if the buyer has one.
- At the model home. Ask what is included in the base price versus an upgrade, whether the model reflects base finish, which plans are available on which lots, the current incentive and exactly what qualifies for it, how many homes are left in this phase, and the direction of the last price change.
- The incentive, decoded. Is it tied to the builder's preferred lender, a closing date, or a specific inventory home? Is it a price cut, a closing-cost credit, a rate buydown, or an options allowance, and is a buydown permanent or temporary?
- The lender question. Get a Loan Estimate from the builder's lender and from at least one outside lender; compare rate, points, fees, and actual cash to close, not just the headline rate.
- The lot. What is the lot premium buying, what is planned behind and beside it, how does it drain, which way does the back yard face, and are there setbacks that limit a future pool or casita.
- The contract. Read every addendum. Confirm the completion window, earnest money terms, whether an appraisal or inspection contingency exists, and whether third-party inspections are permitted.
- Design center. Separate structural choices that must be made now from cosmetic choices that are cheaper to do later.
- During the build and at closing. Track milestones, get an independent inspection at pre-drywall and final, and calendar an eleven-month inspection before the workmanship warranty year closes.
Working a builder-provided list with consent
If a builder or a buyer hands you a list of names to follow up with, the registration card's own consent language decides whether you may text. Most cards were not written with texting consent in mind; treat any list without explicit texting consent as email-first, and follow the reply-first rule before texting anyone who has not first replied to you. Chapter 05 covers the full TCPA, A2P 10DLC, and reply-first mechanics; this chapter does not repeat it.
For the buyer's agent: daily desk
Claude workflow: builder comparison sheet for one buyer
Trigger: a buyer is choosing between two or more communities or plans.
What Claude prepares: a one-page comparison built from the weekly tracking sheet plus the buyer's stated must-haves (bedrooms, garage, lot orientation, budget ceiling), laying out price, incentive terms, plan, and estimated close date side by side.
What the human checks and does: calls each sales office to verify price and incentive are still current before presenting the sheet to the buyer, since inventory and incentives change without notice.
What is never automated: the verification call, and any recommendation about which home to choose, which stays the buyer's decision informed by the agent.
Claude workflow: weekly inventory change note
Trigger: this week's tracking sheet is filled in for a community the agent's active buyers are watching.
What Claude prepares: a diff against last week's sheet (new homes, price changes, incentive changes, homes that sold) and a short draft note to active buyers watching that community.
What the human checks and does: confirms the diff against the actual sheet before sending, and sends from the agent's own account.
What is never automated: the send, and the underlying weekly site visit that produced the sheet.
For the on-site new-home sales rep: daily desk
The daily traffic log: every visitor, registered or not, with the community, the plan they liked, and whether they came with an agent. This is the raw material for every follow-up and for verifying the registration rule was followed.
Claude workflow: appointment prep desk
Trigger: a buyer or a buyer's agent has a scheduled appointment.
What Claude prepares: a short prep sheet: the questions worth asking this buyer, a summary of the buyer's file (budget, must-haves, prior visits) if the rep has one, and the community facts the human has already confirmed (current incentive, available plans, phase inventory).
What the human checks and does: confirms every community fact in the prep sheet is still current before the appointment; nothing in the sheet should be presented to a buyer as current without that check.
What is never automated: pricing quotes, incentive terms, or any statement about qualification, all of which the rep confirms live.
What the rep may not do if unlicensed. Arizona's ADRE Substantive Policy Statement on unlicensed assistants governs on-site staff who are not licensed salespersons: unlicensed personnel generally may not negotiate price or terms, procure buyers, or receive commission-based pay tied to a specific sale report. The full policy text was not independently confirmed in a text-extractable form for this guide, so treat this as a flag, not a complete statement of the rule, and check current status with ADRE or your broker of record before assuming what an unlicensed rep can say in a negotiation counsel check.
What stays human
- Registering the buyer, in person or by pre-registration, on the first visit to any new community.
- Verifying co-op compensation per community, in writing, every time. Never assume last quarter's number.
- Every phone call confirming current price, incentive, or plan availability before it goes in front of a buyer.
- The weekly builder-site visit that feeds the tracking sheet. Claude never scrapes or browses a builder site.
- Any negotiation of price or terms, which stays with the licensed agent or rep, never an unlicensed assistant.
Do this today
- Confirm, in writing, the registration policy at the next new-construction community you or your buyer plan to visit.
- Set up the weekly tracking sheet for one active community and fill in the first week by hand.
- If you supervise or work as an unlicensed on-site assistant in Arizona, pull ADRE's current Substantive Policy Statement on unlicensed assistants and confirm what is and is not allowed with your broker.

Starting from zero? Use the field manuals first.
02 · BEFORE YOU BUY SOFTWARE
If you're still choosing the buyer, offer, stack, agents, content, customers, and delivery, don't start with a tool: start with the manuals. These create local worksheets only: no checkout, outreach, or account setup.
Find the first manual
Not sure which guide to open first? Start from your stuck point and let the finder recommend the next manual and the first worksheet question. No personal data is collected: it just points you at the right starting move.
Work the starter pack
Move through buyer, offer, stack, agents, content, customers, and delivery as a sequence of short local worksheet sessions. One artifact at a time, in order, so you build the business instead of browsing for it.
See what "done" looks like
Read a fully worked field manual before writing your own version, so the output feels concrete: a real, numbered workflow with the risky steps gated, not a fake proof claim.
