PropTech Valuation Platform for NexaRealty

NexaRealty agents were producing manual CMAs that took 3+ hours each and relied heavily on subjective judgment. Valuation variance between agents on identical properties exceeded 15%, causing deals to fall apart and client trust to erode.

For many Real Estate organizations across the United States, this type of operational bottleneck is all too familiar. Manual processes, legacy systems, and disconnected workflows create compounding inefficiencies that cost both time and revenue — often without leadership having a clear line of sight into the true cost.

NexaRealty needed a partner who understood the technical complexity and the business urgency. Delivery speed mattered, but so did long-term maintainability, security, and the ability to scale as the business grew.

We built an AVM platform trained on 5M+ historical transactions, integrating MLS data, tax records, satellite imagery features, and local market indicators. The system generates valuations in under 30 seconds with confidence intervals and comparable selection transparency.

Our engineering team architected the solution with production scalability in mind from day one — not as an afterthought. Every component was evaluated against real-world load expectations, and the system was designed to handle growth without requiring expensive re-architecture six months after launch.

We maintained weekly video demos with NexaRealty's leadership throughout the build. This meant no surprises at launch and full stakeholder alignment at every milestone. Every sprint delivered working, tested software — not just progress reports.

We trained gradient boosting models on geographic micro-markets, with separate models for property types. An LLM layer generates the narrative explanation of valuation factors. Agents review AI output and can override with documented justification.

The Real Estate sector in the United States is undergoing rapid digital transformation. Organizations that invest in custom software and AI-powered automation today are building structural advantages that will be extremely difficult for competitors to close — lower cost structures, faster response times, and better customer experiences compounding year over year.

This project for NexaRealty is a strong example of what's achievable when business requirements are clearly defined, technology choices are made deliberately, and delivery is structured around measurable outcomes rather than billable hours.

For US companies in the Real Estate space evaluating similar investments: the ROI case is typically clearer than expected, and the risk is manageable with the right partner and the right contract structure. Fixed-price engagements with milestone-based payments and clear acceptance criteria protect both sides and keep projects on track.
