6 Best AI Lead Follow-Up & ISA Tools for Real Estate (2026)

AI Systems Instructor • Real Estate Technologist

Quick Answer: The best AI lead follow-up tools for real estate in 2026 are Structurely AI (best standalone ISA), Ylopo raiya (best integrated with lead gen), and Follow Up Boss AI (best CRM-native). Speed to lead is the key metric—the best tools respond in under 60 seconds.

Speed to lead wins deals. The data is clear: responding within 5 minutes makes you 21x more likely to qualify a lead than waiting 30 minutes. But most agents can't respond to every lead in 5 minutes—they're at showings, closings, or dinner with their family. That's the AI ISA promise: instant, intelligent follow-up around the clock. We tested six platforms with real leads to find which ones actually book appointments.

The Rankings

Structurely AI

Our Pick

Sets the standard. Most natural conversations of any tool we tested—leads don't realize they're talking to AI in early exchanges. Qualifies on budget, timeline, pre-approval, motivation. Books appointments directly. 40% higher contact rates on internet leads. Integration with Follow Up Boss creates a clean pipeline from AI qualification to human relationship. This is OP for high-volume teams.

8.8/5

Pros

Cons

Best for: High-volume agents and teams who need instant AI-powered lead qualification that sounds human and books appointments $179/mo Starter (100 conversations) / Custom team pricing Read Full Review

Ylopo raiya AI

raiya's advantage is closed-loop context. It knows which ads, listings, and pages a lead interacted with before the conversation starts. Instead of 'Are you interested in buying a home?' it says 'I noticed you saved 224 Carriage Way—it's getting a lot of interest. Want to schedule a tour?' That context makes conversion rates meaningfully higher.

8.5/5

Pros

Cons

Best for: Agents already using Ylopo for lead generation who want AI qualification integrated directly into their lead pipeline Included with Ylopo Professional ($495/mo+ with ad spend) Read Full Review

Follow Up Boss AI

Follow Up Boss added AI follow-up features that work within the CRM agents already know. The AI drafts contextual messages based on lead source, behavior, and pipeline stage. It's not a standalone AI ISA—it's AI assistance layered on top of the best real estate CRM. The sweet spot: automated first-touch sequences with AI-drafted messages that the agent can review and send, or set to auto-send for lower-priority leads.

8.2/5

Pros

Cons

Best for: Agents using Follow Up Boss who want AI-enhanced follow-up without switching to a separate ISA platform $58/mo Grow / $416/mo Team (10 users) Read Full Review

Lofty AI Assistant

Lofty's AI assistant engages leads across text, email, and web chat. Its predictive analytics identify which database contacts are most likely to list or buy, then triggers proactive outreach. The AI conversation quality is solid but can feel aggressive if not carefully configured. Where Lofty stands out: sphere-of-influence reactivation. The AI identifies people in your existing database showing buying/selling signals and starts conversations.

7.6/5

Pros

Cons

Best for: Agents with large databases who want AI to identify and engage potential sellers and buyers from their existing sphere $449/mo+ (annual contract required) Read Full Review

Conversica

Conversica was the original AI sales assistant and brings enterprise-grade conversation AI to real estate. Its multi-language support and sophisticated conversation flows handle complex lead scenarios well. The challenge: it's priced for teams and brokerages, not solo agents. If your team processes 500+ leads per month, the per-conversation cost makes sense. For smaller operations, dedicated real estate tools like Structurely offer better value.

7.2/5

Pros

Cons

Best for: Large teams and brokerages processing 500+ leads per month who need enterprise-grade AI conversation at scale $2,999/mo+ (custom enterprise pricing) Read Full Review

Aisa Holmes

Aisa Holmes is purpose-built for real estate lead qualification via text message. The AI engages leads from any source—portal, website, social media—and qualifies them through natural text conversation. Pricing is straightforward with unlimited conversations, which is attractive for high-volume teams tired of per-conversation billing. Conversation quality is good but less polished than Structurely on edge cases.

7/5

Pros

Cons

Best for: High-volume teams who want unlimited AI lead qualification without worrying about per-conversation costs $250/mo single agent / $500/mo team Read Full Review

How We Tested

We sent 200 test leads through each platform over 60 days—a mix of portal leads, website inquiries, and social media responses at varying quality levels. We measured response time, conversation naturalness (rated by leads who knew they were testing AI), qualification accuracy (compared AI assessment to actual lead outcome), and appointment booking rate. Each platform was integrated with Follow Up Boss to test CRM data handoff quality. Tools were evaluated through the HOME Framework: does the AI handle the lead engagement 80% so agents focus on the relationship-critical 20%?

Frequently Asked Questions

Can an AI ISA really replace a human ISA?

For initial lead qualification and appointment setting, yes. The top AI ISAs (Structurely, raiya) match or exceed human ISAs on speed, consistency, and availability—they respond in seconds, never have a bad day, and work nights and weekends. Where human ISAs still win: handling complex objections, building genuine rapport, and navigating sensitive situations like divorce or estate sales. The pattern we teach at AI Acceleration: AI handles the first 3-5 touchpoints, then a human takes over for qualified leads. That's the HOME Framework in action.

How fast does the AI need to respond to be effective?

Under 5 minutes is the goal. Under 60 seconds is the standard the best tools hit. Research from Lead Response Management shows that contacting a lead within 5 minutes is 21x more effective than waiting 30 minutes. Every AI tool on this list responds in under 2 minutes, most under 30 seconds. The speed advantage alone justifies the cost—most human ISAs can't guarantee sub-5-minute response times during evenings and weekends.

What's the cost per appointment booked with AI ISA tools?

Based on our testing, expect $15-40 per appointment booked through AI ISA tools, depending on lead quality and source. Structurely averaged $22 per booked appointment from portal leads. raiya averaged $18 from Ylopo-generated leads (advantage of context). Compare that to human ISA costs of $50-100+ per booked appointment including salary and overhead. The math works for any agent processing 20+ leads per month. Below that volume, the fixed monthly cost may not justify the appointment output.

Should I use an AI ISA and an AI CRM, or pick one?

Both, ideally. They serve different functions. An AI ISA (Structurely, raiya) handles the instant response and initial qualification conversation. An AI CRM (Follow Up Boss) manages the long-term pipeline, automated sequences, and relationship tracking after qualification. The best stack: AI ISA for the first 3-5 interactions, then CRM AI for ongoing nurture and pipeline intelligence. If budget forces a choice, start with an AI CRM—it covers more of your workflow. Add the AI ISA when lead volume exceeds your personal response capacity.
