How Coin Show Experiences Are Shaping the Future of PropTech and Real Estate Software

The real estate industry is changing fast, and technology is leading the charge. As a PropTech founder and real estate developer, I’ve watched traditional practices merge with digital tools in surprising ways. One unexpected source of inspiration? The 2025 Rosemont/Chicago Great American Coin Show. At first glance, coins and real estate feel worlds apart—but look closer, and you’ll see how the habits and innovations of coin collectors are shaping the next generation of real estate software.

The Analog to Digital Transition in Real Estate

At the coin show, I watched dealers and collectors trade rare coins like seasoned investors. It felt a lot like real estate transactions—paper trails, provenance, handshake deals. But just as digital tools are transforming coin collecting (think online auctions, digital verification), PropTech is reshaping how we buy, sell, and manage property.

Both industries share a common truth: trust matters. And the best way to build trust today? Transparency through digitization. Coins get verified with grading reports. Properties should get the same treatment—digitally.

Digitizing Property Management

Modern property management systems (PMS) are moving beyond spreadsheets. Forward-thinking teams now use digital ledgers—sometimes blockchain—to record everything from ownership changes to maintenance history. It’s like a coin’s pedigree, but for real estate.

This isn’t just about security. It’s about speed. When a buyer can instantly verify a property’s full history, transactions close faster. And when disputes arise, the record speaks for itself.

Actionable Takeaway: If you’re still tracking property history manually, now’s the time to explore digital record solutions. Look for PropTech companies offering tamper-proof ledgers—or consider building one tailored to your portfolio.

API Integrations with Zillow/Redfin

Coin dealers don’t just stand at tables—they post online, use social media, and list on multiple platforms. Smart real estate teams do the same. That’s why seamless integration between your PMS and marketplaces like Zillow and Redfin isn’t optional anymore.

When your system talks directly to these platforms, listings update instantly. Price changes, availability, even photo swaps—everything stays in sync. No more double work. No more missed opportunities.

Example integration code:


// Example: Updating a property listing via Zillow API
const axios = require('axios');

async function updateZillowListing(listingId, updates) {
try {
const response = await axios.put(
`https://api.zillow.com/v1/listings/${listingId}`,
updates,
{
headers: {
'Authorization': 'Bearer YOUR_ZILLOW_API_KEY',
'Content-Type': 'application/json'
}
}
);
console.log('Listing updated:', response.data);
} catch (error) {
console.error('Error updating listing:', error.response.data);
}
}

// Usage
updateZillowListing('12345', { price: 450000, status: 'For Sale' });


Smart Home Technology and IoT in Real Estate

At the show, dealers checked every coin’s details—weight, edge, surface marks. They treated authenticity like a religion. In smart homes, data plays that role.

IoT devices—smart thermostats, water sensors, security systems—generate a constant stream of information. When this data flows into your PropTech platform, you get real-time visibility into a property’s health.

IoT for Property Monitoring

Picture this: A water leak starts in a basement. Sensors detect it within minutes. Your system alerts the property manager and auto-schedules a plumber. No damage. No angry tenant. Just smart prevention.

That’s the power of IoT. It turns reactive maintenance into proactive care—cutting costs and keeping tenants happy.

Actionable Takeaway: Start small. Install a few sensors on high-risk properties. Choose devices with reliable API access so you can build custom alerts and workflows. And always, always prioritize security.

Smart Home Features as Selling Points

Just like a rare coin’s history boosts its value, smart features add real appeal. Buyers and renters today want convenience, safety, and efficiency—and they’re willing to pay for it.

A National Association of Home Builders study found 65% of buyers pay more for smart homes. In competitive markets, that’s the difference between a fast sale and a long wait.

From energy-saving thermostats to voice-controlled lighting, these aren’t gimmicks. They’re expectations.

Data-Driven Decision Making

Coin dealers don’t guess values. They study price trends, rarity scores, and market demand. The best PropTech platforms do the same—using data to guide every decision.

With the right tools, you can predict maintenance needs, spot tenant turnover risks, and even forecast neighborhood growth. It’s not magic. It’s math.

Predictive Analytics for Property Management

Imagine knowing—three months in advance—when a tenant might leave. Or which units need a fresh coat of paint before summer. Predictive models make this possible by analyzing lease history, maintenance logs, and market patterns.

The result? Fewer vacancies. Lower costs. Higher profits.

Actionable Takeaway: Begin by collecting more data—tenant feedback, repair timelines, utility usage. Then feed it into analytics tools like Power BI or Tableau. Even simple models can reveal powerful insights.

Market Trend Analysis with Redfin API

Redfin’s API gives you a real-time window into local markets. Home prices, demand spikes, inventory changes—all available with a few lines of code.

Use it to time purchases, set competitive rents, or spot up-and-coming neighborhoods before they heat up.

Example integration:


// Example: Fetching market trends from Redfin API
const fetchMarketTrends = async (city) => {
const url = 'https://api.redfin.com/v1/market-trends';
const params = {
city: city,
regionType: 'city',
timePeriod: '12M'
};

try {
const response = await axios.get(url, { params });
return response.data;
} catch (error) {
console.error('Error fetching market trends:', error.message);
}
};

// Usage
fetchMarketTrends('Chicago').then(data => {
console.log('Market trends:', data);
});


Enhancing User Experience with Technology

The coin show buzzed with energy—people handled coins, asked questions, compared details. It was interactive, personal, real. In PropTech, we need to recreate that experience online.

That’s where virtual tours, AR, and 3D models come in. They don’t just show a property. They let people feel it.

Virtual Tours and AR

With AR-powered tours, buyers can walk through a home from their couch. They can measure rooms, view floor plans, even see how furniture might fit. Some platforms overlay renovation history or energy ratings right into the tour.

It’s not just convenient. It builds confidence. And confident buyers act faster.

Actionable Takeaway: Start with tools like Matterport or Zillow 3D Home. For high-end listings, consider custom AR experiences using Unity or Unreal Engine. Think of it as a digital open house—available 24/7.

3D Modeling for Property Development

Before shovels hit the ground, 3D modeling helps developers test designs, spot flaws, and win over investors. One team I know used a detailed model to pre-sell 70% of a luxury condo—before construction began.

Tools like SketchUp and Revit make this accessible, even for small projects. The key? Involve stakeholders early. Let them see, touch, and suggest changes—virtually.

Conclusion

The coin show reminded me that even in a digital age, people connect with stories, details, and trust. PropTech isn’t about replacing the human touch. It’s about enhancing it.

By digitizing records, integrating Zillow/Redfin APIs, using IoT for smarter homes, and letting data guide decisions, we’re not just modernizing real estate. We’re making it more transparent, efficient, and personal.

The future of real estate isn’t just code and cameras. It’s about blending the tangible—the feel of a home, the thrill of a rare find—with the power of technology.

As I walk the PropTech path, I keep the coin show in mind. Whether you’re managing a portfolio, developing property, or investing in the next big idea, remember: the best tech feels human. And that’s where real transformation begins.
