Missed Calls Are Costing South Florida Agents and Property Managers More Than They Think

Disclosure: I'm a Marblism partner. I earn a commission if you sign up through my link. I haven't run a real estate or property management business on Marblism myself, so this post sticks to public research and what the product's own pages say it does.

If you sell homes or manage rentals in Broward, Palm Beach, or Miami-Dade, your phone rings at the worst times. A buyer calls about your listing mid-showing. A seller calls on Sunday night. A tenant calls at 1 a.m. because water is coming through the ceiling. A renter wants a Saturday showing, and nobody calls back until Monday.

I'm a software engineer in Coral Springs who builds AI agents. When I look at where local businesses lose work, it's rarely pricing or marketing. It's the call nobody picked up, or picked up too late.

What the research says about missed calls and slow follow-up

These are the numbers I could trace to an original source. I left out the ones I couldn't.

• Most buyers and sellers only talk to one agent. In NAR's 2025 Profile of Home Buyers and Sellers, 74% of buyers interviewed only one agent, and 80% of sellers contacted only one agent before picking the one who sold their home. Phone was the most common way buyers first reached their agent (26%). If most people only ever talk to one agent, being the one who answers matters.
• Unanswered callers move on. In a September 2025 survey of 1,000 U.S. consumers, CallRail found that when a business doesn't answer, only 42% leave a voicemail and 21% immediately call another business. 78% said they have taken their business elsewhere after failing to reach a company by phone.
• Speed-to-lead is real. A Harvard Business Review study of 1.25 million sales leads (2011) found that firms that tried to contact a lead within an hour were nearly seven times as likely to qualify it as firms that waited even an hour longer, and more than 60 times as likely as firms that waited 24 hours or more.

None of these studies is about your brokerage or your portfolio, but they point the same way: a buyer who just saw your sign usually doesn't wait for a callback. They call the next name in the search results.

Two different phone problems

Agents: speed-to-lead. Buyer and seller inquiries come from signs, portals, open houses, and referrals, often at night and on weekends. You can't answer during a showing or a closing, and a 9 p.m. voicemail often becomes a callback the next afternoon. By then the buyer may have booked a showing with someone else.

Property managers: volume and after-hours. Your calls mix prospects asking about showings, tenants with maintenance requests, and a few real emergencies. You can't tell which call is the leak until someone answers. South Florida adds hurricane season, summer storms, and a lot of callers who'd rather speak Spanish, Haitian Creole, or Portuguese.

The usual fixes have trade-offs. Answering everything yourself burns you out. An assistant covers business hours, not nights and weekends. A traditional answering service takes messages but usually can't book a showing.

What an AI receptionist actually does

An AI receptionist is software that answers your business line in a natural-sounding voice and handles the call the way a trained front-desk person would. A good one should:

1. Answer every call, 24/7, including evenings, weekends, and the morning after a storm.
2. Answer common questions from what you teach it: office hours, which areas you cover, how showings work, how tenants submit a maintenance request.
3. Book the appointment (a listing consultation, a buyer call, a rental showing) into your calendar while the caller is on the phone.
4. Hand off emergencies by transferring the call to you or your on-call person, with a text summary first.
5. Give you a record of every call (a transcript or summary) so nothing gets lost.

It covers the calls nobody was going to get to anyway.

How to evaluate one: a checklist

Before you sign up for any AI receptionist, test these yourself:

• Call it. Call the demo line at a bad time. Interrupt it and act like a stressed tenant or an impatient buyer.
• Emergency handoff. Can it tell "there's water pouring through my ceiling right now" from "my faucet drips"? For fire, a gas smell, or anyone hurt, it should tell the caller to call 911 first, then reach your on-call person fast. It should never promise a repair time you haven't approved.
• Showings and calendars. Does it book into the calendar you actually use? If your showings run through your MLS's showing service, check whether it can work with that, or only with your own calendar.
• Your existing number. Can you forward your current line to it, or do you have to advertise a new number?
• Language. Test it in Spanish, and in Haitian Creole or Portuguese if your callers need that.
• Call recording and consent. Florida generally requires all parties to consent before a phone call is recorded (Fla. Stat. § 934.03). If the tool records or transcribes calls, ask how it tells callers, and check with your attorney.
• Outbound calls. Answering inbound calls is one thing. If any tool places AI-voice calls for you (old leads, expired listings), the FCC confirmed in February 2024 that AI-generated voices fall under the TCPA, so those calls require the called party's prior express consent.
• Fair Housing. What the AI says for you is a statement about housing. Federal law (42 U.S.C. § 3604) and Florida law (Fla. Stat. § 760.23) prohibit statements that indicate a preference or limitation based on race, color, national origin, religion, sex, disability, or familial status. Local ordinances can add more. Script it to give every caller the same facts about the property, to stay out of questions like "is this a good area for families?" or "who lives around here?", and to send accessibility, service-animal, and accommodation questions to a person. Read the transcripts in the first few weeks.
• Pricing math. Ask what's included and what costs extra. Compare that to what one closed deal or one filled vacancy is worth.
• Exit. Is there a trial or refund window, and can you cancel without a long contract?

Where Marblism fits

Marblism sells a team of "AI employees" for small businesses. Its receptionist, Rachel, is the one that matters here. According to Marblism's Rachel page, Rachel:

• gets a dedicated phone number (U.S., Canada, UK, Mexico, and Australia), or you can forward the line you already use
• answers 24/7 in your business's name and answers questions you've taught her about your hours, services, prices, and the areas you cover
• books appointments into a connected Google or Outlook calendar and handles reschedules
• transfers urgent calls to your cell or office line and texts you the caller's name, number, and reason first
• sends a transcript and short summary of every call
• detects the caller's language and switches automatically, including Spanish and French

The page also lists a public demo number (+1 607-303-6540 when I checked), so you can call it before you pay anything.

Rachel comes bundled with Marblism's other AI employees (email, social media, lead generation, SEO, websites, contracts). As of this writing, the pricing page lists plans from $24/month billed yearly or $44/month billed monthly, with 50 hours of AI work a month and paid top-ups after that. The site advertises a 7-day full refund guarantee. Check current terms before you buy, and ask how phone calls count against the monthly hours on a busy line.

My honest take: if your main problem is buyer and seller calls going to voicemail during showings, or tenant calls piling up after hours, a tool like this is cheap enough to test for a week against your own call log. Script your Fair Housing and emergency answers first, then call the demo line at 11 p.m. as your most difficult tenant and decide from there.
