What is Build a Marketplace for Proptech?
Build a Marketplace for Proptech means building a marketplace specifically designed around the workflows, compliance expectations, and user needs of property technology companies and real estate platforms. Unlike generic software or off-the-shelf tools, a custom-built solution gives your team full control over features, data, and the product roadmap — without paying for capabilities you don't need or working around limitations that slow you down.
Real estate technology needs to handle complex property data, multiple stakeholder types (buyers, sellers, agents, property managers), and workflows that vary significantly by market.
Why Proptech companies need custom build a marketplace
Proptech products often need map integrations, complex property data structures, and different views for different user types. Generic tools can't handle the combination of location data, user roles, and transaction logic that real estate workflows demand.
Most proptech teams start with generic tools because they're fast to deploy. But as the business grows, those tools create friction — missing the specific logic, integrations, and workflows that proptech operations actually need. A custom-built product eliminates that friction permanently.
How long does it take to build?
Basic listing platforms can launch in 3–6 weeks. Full property management or transaction platforms take 8–14 weeks. The timeline depends on scope, the number of user types, and the depth of integrations with existing proptech systems. A well-scoped project with clear requirements moves significantly faster than one that evolves through the build. We scope tightly before starting so timelines stay predictable.
What does it cost?
Proptech builds typically range from $8k–$35k depending on map integrations (Google Maps, Mapbox), property data sources, and transaction complexity. The biggest cost drivers are integration complexity, the number of distinct user roles, and whether the product needs to handle regulated data or compliance workflows. We provide a clear scope and fixed-price quote before any work begins.
Custom build vs. off-the-shelf tools
Off-the-shelf tools work well for standard use cases. But proptech companies often have requirements that generic SaaS tools weren't built for: property data structures that don't fit standard database templates, multiple user types (buyers, sellers, agents, managers) needing different views, or workflows that don't fit the assumptions baked into general-purpose platforms.
A custom-built product gives you:
- Full ownership — no per-seat fees or platform lock-in
- Workflows built exactly for how proptech teams operate
- Integrations with the tools and data sources you already use
- A foundation you can extend as your product and team grow
The right time to build custom is when generic tools are creating real friction, costing more in workarounds than a custom build would cost, or blocking product-critical workflows that your proptech business depends on.

Proptech MVP questions answered
What makes custom proptech different from building a generic marketplace?+
Proptech requires property data structures (address, coordinates, valuation, features), multiple stakeholder types (buyers, sellers, agents, managers), maps, and complex workflows. Generic marketplaces can't handle property-specific logic without major hacks. Greta builds property data and workflows at the core: geocoding, boundary search, transaction stages, agent coordination.
Can you integrate maps, property data, and MLS?+
Yes. We integrate Google Maps (free search/display) or Mapbox ($0–$10K/month depending on volume). For property data: MLS APIs (regional, varies by board), Zillow (paid API, limited), or custom data sources. Map features add 2–4 weeks. Data partnerships take 2–8 weeks depending on access level. We handle the integrations; you handle vendor relationships.
What's the timeline for a proptech MVP?+
Listing platforms (search, filters, details, contact agent): 3–6 weeks. Property management (tenant portal, rent collection, maintenance): 8–12 weeks. Transaction platforms (offers, escrow, inspections, signatures): 12–18 weeks. Timeline depends on workflow complexity, not on proptech specifically.
How do you handle real estate transactions with multiple parties?+
Multi-party transactions need: offer workflows (buyer → seller acceptance), title/escrow coordination, inspection stages, financing contingencies, and e-signature integration (DocuSign, HelloSign). We build state machines that track each stage, require approvals, and prevent invalid transitions. Complex, but doable in 12–18 weeks.
Can you build a proptech platform for a specific market (e.g., commercial real estate vs residential)?+
Yes. Commercial vs residential vs land have different workflows, data needs, and regulations. Greta specializes in custom workflows — tell us your market and user types, we build accordingly. Commercial real estate (longer deal cycles, complex financials) needs more sophisticated workflows than residential.
How much does a proptech MVP cost?+
Listing platforms: $12K–$25K. Property management platforms: $20K–$40K. Transaction platforms: $40K–$75K. Location data (MLS, property APIs): $2K–$5K setup + monthly fees. Maps (Google/Mapbox): $0–$5K/month depending on traffic.
How do you handle property search with geographic boundaries?+
We use reverse geocoding (address → coordinates), bounding box search, and radius search for map-based discovery. Google Maps API does geocoding cheaply. Mapbox is similar. Database indexing (PostGIS, MongoDB geo) handles fast geographic queries even with 100K+ properties. Result: instant map search, no lag.
Can you integrate proptech with CRM systems for agents?+
Yes. We integrate custom proptech with agent CRMs (Salesforce, Follow Up Boss, BoomTown). Agent platforms track leads, properties, transactions, and pipelines in one system. Integration adds 3–5 weeks depending on CRM API maturity. Many proptech platforms ARE CRMs for agents — combining property search with lead tracking.
