Real Estate & PropTech Due Diligence – What Investors Need to Know

Real Estate & PropTech Due Diligence – What Investors Need to Know

Why Due Diligence Matters More Than Ever

In today’s investment environment, speed is often prioritised. Deals move quickly, founders want fast decisions, and competition between investors is fierce. But rushing into a PropTech or real estate investment without deep due diligence is a recipe for failure. Many high-profile PropTech firms have collapsed in recent years, not because the idea wasn’t strong, but because investors overlooked critical flaws in business models, compliance, or scalability.

The unique challenge for PropTech is that it sits at the intersection of two industries: property and technology. Each carries its own risks. Combining them multiplies the complexity. That’s why modern due diligence can’t simply copy and paste a checklist from general VC playbooks. It requires tailored thinking.

Key Areas of PropTech Due Diligence

1. Business Model Resilience

Ask: Is this company built to scale in real-world property markets, not just spreadsheets? Many PropTech ideas look elegant in theory but falter when exposed to regulatory hurdles, adoption timelines in construction, or the notoriously slow-moving real estate sector.

2. Data Integrity and Technology

In PropTech, data is both the product and the risk. Investors need to stress-test how accurate, reliable, and unique a company’s datasets are. Do they depend on public data anyone can access? Do they rely on scraping methods that may breach terms of service? A great algorithm on weak data is worthless.

3. Regulatory and Compliance Alignment

Unlike pure-play SaaS, PropTech companies are exposed to real estate regulations, planning law, building codes, anti-money laundering requirements, and more. Due diligence must go deeper than legal entity checks. It should assess whether the company’s compliance frameworks can keep pace as it scales.

4. Commercial Traction vs. Vanity Metrics

Startups often emphasise downloads, demo requests, or site traffic. In PropTech, the critical question is: Who’s paying, and how sticky are they? A single pilot project with a large developer is encouraging, but recurring revenue across multiple clients is far more telling.

5. Real Estate Domain Knowledge

A red flag is when a PropTech founding team has strong technical skills but little experience in real estate. The inverse can also be true. Successful PropTech businesses tend to blend both skill sets, a team that understands the pain points of developers, planners, and agents while also being capable of building scalable technology.

How PropTech Complicates Traditional Due Diligence

Traditional VC due diligence usually covers team, market, product, legal, and financials. In PropTech, every category is more nuanced:

• Market Size: Real estate is huge, but the slice addressable by a given PropTech tool might be small. Is the company overestimating its TAM?
• Team: Does the leadership have credibility in both property and technology?
• Product: Does the tech actually integrate with existing real estate workflows, or does it require behaviour changes that the market resists?
• Financials: Property cycles can dramatically affect adoption. What happens to the business model in a downturn?

Real Estate Due Diligence for Investors

When investors back PropTech, they’re indirectly betting on real estate assets and workflows. That makes it vital to apply real estate due diligence thinking too:

• Title and Ownership Risks – Is the company exposed to ownership disputes or data reliability issues?
• Planning and Zoning Exposure – Does the product rely on planning outcomes beyond the company’s control?
• Partnership Dependencies – Does the model depend on ongoing cooperation from developers, councils, or data providers?

What Smart Investors Do Differently

1. Simulate Stress Scenarios – Test how the business survives in a housing downturn, or when regulation shifts.
2. Talk to Customers, Not Just Founders – Direct customer feedback often reveals whether the product is mission-critical or a nice-to-have.
3. Check Tech Debt – Many PropTech firms rush to market with fragile prototypes. Review the codebase, not just the demo.
4. Validate ESG Claims – Sustainability is a big PropTech theme. Investors should confirm whether the company’s carbon or housing affordability claims are measurable and defensible.

Conclusion

Due diligence in PropTech isn’t a box-ticking exercise. It’s about asking harder questions that sit between two industries. Investors who adapt their approach stand a far better chance of avoiding high-profile failures and backing businesses that truly transform real estate.
