From Data to deals: The new property currency

• Data without insight is noise; insight drives pricing power and smarter deals.
• 30 years of property data fuels AI-driven, bank-grade valuations.
• Western Cape demand, ageing buyers, and bond trends reshape strategy.

Lightstone’s valuation edge

‍‍

“Data turns uncertainty into insight, insight into action, and action into advantage.”

‍

That was the core message from Hayley Ivins-Downes at the eXp Conference and it landed squarely with estate agents navigating a complex 2026 market.

We are living in a world of roughly 149 zettabytes of data. That’s 21 zeros. Smartphones, AI, satellite imagery, cloud systems, data surrounds every transaction we touch.

But here’s the truth: data on its own is useless. If you’re not turning it into pricing intelligence, buyer insight, and negotiation confidence, you’re guessing, not advising.

Lightstone’s power lies not in collecting data, but in transforming it into decision-making advantage.

The Property Landscape: What the numbers really say

South Africa has approximately 8.56 million properties, spanning residential and non-residential stock. That database stretches back three decades giving Lightstone near-complete national coverage.

Key structural insights:

• Only 30% of properties are bonded (many assume it’s far higher).
• Estates command around 50% price premiums over freehold homes.
• Gauteng leads in volume; Western Cape leads in growth momentum.

For agents, this matters. It tells you where demand is concentrated, where lifestyle premiums exist, and how financial exposure is distributed.

The Western Cape Effect

‍One of the clearest shifts over the past decade has been value growth in the Western Cape. Semigration accelerated post-2020. Remote work allowed flexibility. Demand surged. Prices followed.

Today:

• Western Cape achieves is closer to 91 - 92% of asking price.
• Gauteng averages under 90%.
• Days on market are shorter in the Western Cape (mid-70s to 80s) versus around 90+ in Gauteng.

Translation? Demand concentration creates pricing resilience.

Agents who understand this can position stock differently, price more strategically, and manage seller expectations with data, not emotion.

The Buyer Shift: Why first-time buyers are older

‍Ten years ago, the average buyer age was around 30.

Today? It’s 38. That’s a major signal.

It means affordability pressure has increased. Entry into property ownership is delayed. Agents must now engage financially mature, often dual-income, buyers who may be more risk-conscious and data-driven.

Pricing and financial advice need to reflect that.

The Heartbeat: AI-Powered valuation models

‍Lightstone’s Automated Valuation Model (AVM) is where data becomes actionable. Banks have used it for two decades. Today, it’s AI-enhanced and recalibrated monthly.

Two core metrics drive lending decisions:

• Confidence Score - How accurate is the valuation estimate?
• Safety Score - What is the probability the value is not under-estimated?

For example: If a property is valued at R1 million, the system may show 75% confidence within a defined range, and 88% safety that value exceeds a threshold.

Banks set internal rules around these scores to approve bonds faster and more efficiently.

For agents, this means:

• Faster approvals
• Less friction
• Better price counselling
• Fewer collapsed deals

That’s competitive advantage.

AI beyond the obvious

Lightstone isn’t just analysing deeds data.

They integrate:

• Satellite and drone imagery
• Roof types and structural detection
• Pool identification
• Area under roof measurement (often missing from deeds)
• Weather and fire risk modelling

This enhances valuation precision and insurance modelling. In short: the model sees more than the eye.

Market Cycles: COVID, rates and recovery

‍The 2020 - 2022 period was buoyant, record-low interest rates drove transaction spikes.

Then rate hikes cooled momentum. Now, with rates stabilising and easing, activity is beginning to pick up again.

Transaction volumes dipped during COVID, surged during low-rate years, tapered during tightening cycles and are now flickering upward again in 2025 - 2026.

Agents must understand the lag in deeds data and interpret momentum shifts early.

Time on market & price realities

‍Days on market and percentage achieved of asking price are powerful pricing tools.

If Gauteng takes longer to sell and achieves lower percentages, overpricing becomes dangerous.

If Western Cape stock moves faster at higher achieved percentages, strategic pricing can protect margin.

Data gives you negotiation authority.

The three pillars of trusted AI

‍Hayley highlighted three foundational pillars:

1. Transparency - Human oversight remains central.
2. Integrity - Lightstone is Africa’s only member of the European AVM Alliance.
3. Outcomes - Faster banking decisions, higher efficiency, sharper pricing intelligence.

This is narrow AI, focused precision on residential valuation accuracy. Not hype. Focus.

Why this matters for Agents

‍Data-backed pricing:

• Builds seller trust
• Protects commissions
• Reduces time on market
• Strengthens negotiation position
• Supports bond approval conversations

In a competitive environment, agents without data are opinion-based. Agents with data are advisory-led. That’s a big difference.

Insight creates advantage

‍The property market doesn’t reward guesswork. It rewards accuracy. Lightstone’s role is not to replace human judgement, it’s to empower it. The agent of the future is not just a deal-maker. They are a data interpreter.

And in a market shaped by semigration, shifting buyer age, bond dynamics, and AI-powered valuation, those who understand the numbers will lead. Because in property, uncertainty is expensive. Insight is profitable.
