The market

Real estate is being transformed by technology

PropTech is one of the fastest-growing sectors in technology investment globally. Platforms connecting buyers, sellers, tenants and landlords digitally are redefining how properties are bought, sold and rented. Successful real estate marketplaces combine intelligent search, identity verification, secure payments and exceptional user experience.

Building a real estate marketplace is one of the most complex technical challenges in product development. It's not just about listing properties: you need a matching system that connects supply with the right demand, identity and property verification processes that comply with regulations, payment gateways supporting deposits, reservations and monthly payments, and precise geolocation search that works with thousands of simultaneous properties.

Moreover, PropTech marketplaces must manage two sides of the market with different needs. Landlords want visibility, tenant screening and contract management. Buyers and tenants seek transparency, easy comparison and a frictionless hiring process. The balance between both sides determines the platform's success, and technology is the fundamental enabler.

At Soamee we have direct PropTech experience. We built Invisible Inícios, an off-market property marketplace in London with over 80,000 registered buyers and AI matching. We developed ElDomi, a comprehensive property management platform. And we created TrasterOne, the storage space rental marketplace connecting supply and demand with geolocation search. We know the technical and business complexities because we have solved them in production.

Key features

What we build for your PropTech marketplace

From intelligent matching to secure payments, every component designed to scale and build trust.

Buyer-seller matching

AI algorithms that connect buyers with relevant properties based on explicit preferences, browsing behavior, budget and desired location. The system learns from each interaction to progressively improve recommendations. Smart notifications when a matching property appears, increasing conversion rates.

KYC/KYB verification

Integrated identity verification processes compliant with anti-money laundering and data protection regulations. Document verification, property ownership checks, solvency analysis and risk scoring. Integration with providers like Onfido, Veriff or Jumio to automate the process and reduce user friction.

Integrated payments

Payment gateway designed for real estate: reservation deposits, earnest money, rental monthly payments, split commissions between agent and landlord, and conditional refunds. Integration with Stripe Connect or Mangopay for escrow fund management. PCI DSS compliance and automatic receipt and invoice generation.

Geolocation search

Search engine with advanced filters (price, area, bedrooms, type) combined with precise geographic search. Interactive maps with property clustering, zone polygons, commute time calculations and nearby points of interest. Search by address, neighborhood, city or area drawn on the map. Optimized for catalogs of thousands of properties.

Communication and negotiation

Internal messaging system between buyers, sellers and agents with complete conversation history. Integrated offer and counteroffer functionality, visit scheduling with synced calendar and video conferencing for virtual tours. Multi-channel notifications (push, email, SMS) configurable by user.

Document management and contracts

Centralized document repository per property and transaction: photos, floor plans, habitability certificates, energy certificates and contracts. Automatic contract generation with customizable templates. Integrated electronic signature with legal validity. Complete traceability of the document process.

FAQ

Perguntas frequentes about PropTech marketplaces

How long does it take to develop a real estate marketplace?

A PropTech marketplace MVP with core features (property listings, geolocation search, user profiles and messaging) can be in production in 10-14 weeks. Adding advanced features like AI matching, KYC verification, integrated payments and document management typically requires 4-6 months for the complete version. We always recommend launching with a focused MVP, validating with real users and scaling features iteratively based on usage data.

How does intelligent matching between buyers and properties work?

The matching system combines collaborative filtering with machine learning. First, it uses explicit user preferences (budget, location, property type, bedrooms). Then it enriches the profile with behavioral data: which properties they visit, how long they spend on each, what they save to favorites and what they dismiss. The model learns patterns from similar buyers to anticipate properties they might like. The result is a "Spotify for properties" experience with personalized feeds.

Which payment gateways are suitable for a real estate marketplace?

For real estate marketplaces we recommend Stripe Connect or Mangopay, designed for platform models with multiple parties. They support split payments, escrow funds, recurring payments for rent and conditional refunds. Both comply with PCI DSS and European PSD2 regulation. The choice depends on transaction volume, target countries and whether you need advanced banking features like virtual IBANs.

Can it integrate with existing real estate portals like Rightmove or Zillow?

Yes, we can integrate your marketplace with major real estate portals through their APIs or XML feeds. This allows publishing your platform's properties on external portals for increased visibility, or importing listings from agencies already publishing on those portals. We also integrate with real estate CRMs like HubSpot to synchronize contact and property data. The integration strategy depends on your business model and whether you want to be complementary or alternative to existing portals.

How is scalability managed with thousands of properties and users?

Our architecture scales from hundreds to hundreds of thousands of properties and users. We use PostgreSQL with PostGIS for efficient geospatial queries, Elasticsearch for full-text search with complex filters, Redis for caching frequent results and CDN for optimized images. Infrastructure is deployed on AWS or GCP with auto-scaling. Search performance stays below 200ms even with catalogs of over 100,000 properties.
