CallSphere reference architecture

Real estate is a business of who-answers-first. NAR and Follow Up Boss data show that buyer inquiries that get a response inside 5 minutes convert at **6-8x** the rate of inquiries that wait an hour. But the typical residential agent is in showings, dinners, and closings — buyer inquiries from Zillow, Redfin, Realtor.com, and the team's own site are routinely getting 3-6 hour callbacks.

The pain compounds **after-hours**. Industry data shows ~55% of buyer-side leads come in between 6pm and midnight, plus Saturday-Sunday morning. Inside-sales-agent (ISA) teams cost $500-$1,500/month and only cover 12 hours/day. Most teams still drop after-hours leads.

The second pain is **lead qualification**. Most agents over-spend time on tire-kickers and under-spend on serious buyers. Pre-qualification (timing, financing, area, price band) at first call is high-leverage.

The third pain is **listing inquiry → showing**. A buyer calling about a specific listing wants the address confirmed, school district info, and a showing booked — fast.

## What an AI voice agent can do here

A 2026 real estate voice agent does five things on a single call:

1. **Answers in sub-500ms** day or night.
2. **Pulls live MLS** to confirm address, status (active/pending), school district, HOA, recent comps.
3. **Qualifies the buyer**: timing, financing (cash / pre-approved / needs lender intro), area, price band.
4. **Books a showing** directly into the agent's calendar (Google, Outlook, ShowingTime).
5. **Pushes the lead** to Follow Up Boss / kvCORE / BoomTown / Sierra Interactive / Lofty / OneRoof with structured notes and a call recording.

ElevenLabs, Brilo, Pete & Gabi, and the OneRoof platform are the most active vendors. CallSphere built its Real Estate vertical on the OneRoof integration pattern.

## How CallSphere solves this for real estate teams

CallSphere's **OneRoof Real Estate suite** ships **10 specialist agents** running on the OpenAI Agents SDK over WebRTC:

1. `OR-Reception` — call greeter, intent (buyer / seller / renter / investor)
2. `OR-Buyer-Qualifier` — timing, financing, area, price band
3. `OR-Seller-Lead` — current home, valuation hooks, motivation, timeline
4. `OR-Listing-Lookup` — live MLS pull, status, comps, school district
5. `OR-Showing-Booker` — agent calendar + ShowingTime integration
6. `OR-Renter-Qualifier` — credit band, pets, move-in date, voucher status
7. `OR-Investor-Screen` — cap rate, cash position, portfolio fit
8. `OR-CRM-Pusher` — Follow Up Boss / kvCORE / BoomTown / Sierra / Lofty push
9. `OR-Nurture-Outbound` — outbound follow-up cadence for unbooked leads
10. `OR-QA-Closeout` — post-call summary, sentiment, lead score 0-100

Native integrations: Follow Up Boss, kvCORE, BoomTown, Sierra Interactive, Lofty, Chime, Salesforce, HubSpot, ShowingTime, MLS RETS feeds.

Platform-wide: **37 agents, 90+ tools, 115+ DB tables, 6 verticals, 57+ languages, HIPAA + SOC 2 aligned**. Pricing **$149 / $499 / $1499**, **14-day no-card trial**, **22% affiliate** (perfect for brokerages and team leads).

## Setup steps for a real estate team

1. Start a [trial](/trial), pick the OneRoof Real Estate suite.
2. Connect Follow Up Boss (API key) or kvCORE / BoomTown / Sierra / Lofty.
3. Connect your MLS feed (RETS or Spark API) so the listing-lookup tool can answer questions live.
4. Upload your team roster — agent name, calendar link, license #, specialty.
5. Configure routing rules — by area, price band, lead source, agent on-call.
6. Set the after-hours cadence (we recommend immediate qualify + book; outbound nurture for unqualified).
7. Configure the SMS confirmation channel with the agent's mobile.
8. Forward your team's main line and your Zillow/Redfin lead numbers to the agent.

## ROI math for a 12-agent team

- After-hours buyer inquiries/month: 240 — currently 55% miss/late = 132 leaked/month
- Recovered leads at 30% recovery: 40/month
- Buyer-side commission per closed transaction: ~$8,500 — typical lead-to-close: 5-8%
- Recovered closings: ~2-3/month — recovered GCI: **$17,000-$25,500/month**
- ISA cost saved: $1,200/month
- After-hours agent burnout reduction: not directly measurable, real
- Total recoverable: **~$20,000+/month** vs $499/month CallSphere Pro

## FAQ

**Does it actually push to Follow Up Boss in real time?**
Yes. We use the Follow Up Boss API (events + people endpoints) to push the lead with stage, source, structured notes, and the call recording URL. The agent can also fire FUB action plans.

**Can it pull live MLS data?**
Yes. RETS or Spark API. The agent confirms status (active / pending / sold), days on market, price history, school district, HOA, and recent comps.

**What about the seller side?**
The Seller-Lead agent qualifies motivation, timeline, current home, mortgage status, and books a listing-presentation appointment. We push to FUB with seller_lead tags so the listing agent gets it routed correctly.

**Does it work with Zillow Flex / Premier Agent leads?**
Yes — Zillow Flex can post leads to FUB / kvCORE which the agent then receives + outbound calls within 90 seconds. Speed-to-lead matters most for Flex ROI.

**Can it handle Spanish-speaking buyers?**
Yes — 57+ languages. Spanish is the second-most-used language on the OneRoof suite after English; Mandarin and Vietnamese are growing fastest in coastal metros.
