AI-powered real estate solutions we build
We design and integrate AI models into real estate products, so your team spends less time on lease paperwork and maintenance tickets. A person stays in the loop wherever a decision affects a tenant or a deal.
Lease and document extraction
Pulls rent, dates, renewal options and clauses out of leases and closing documents into structured data your team can search and report on.
Maintenance request triage
Reads incoming tenant requests, sets urgency, routes each one to the right vendor and drafts the reply.
Valuation and pricing models
Rent and price recommendations trained on your own portfolio plus market data, with the reasoning shown next to every number.
Tenant and lead assistant
Answers common questions and books viewings around the clock, then hands complex cases to staff with the full conversation attached.
Predictive maintenance
Models that spot equipment heading for failure from sensor readings and work-order history, so repairs get scheduled before tenants notice.

Since 2012, Building Real Estate and PropTech Software
For more than a decade, we have built and run real estate software for property companies and proptech startups. Every product is delivered by senior in-house engineers who know how a property business runs day to day.
global reach
Our Real Estate Software Development Process
Discovery
A look at your properties and the systems you already run. You get a scope and a realistic budget range before any build starts.
Design and prototype
User flows and clickable prototypes, tested with real tenants or property staff where possible.
Build and integrate
Two-week sprints with working demos. Integrations with your platforms and hardware are built and tested early, since that is where surprises usually live.
Pilot
Launch in one building or one region first. We watch real usage and fix what the pilot shows before the wider rollout.
Rollout and support
Portfolio-wide release, with ongoing development as your needs change.
A few quick questions show which kind of project yours most likely is.

PropTech Software Development Projects

Goldfarb Properties
Rental app with a smart-lock key
A rental app for a New York landlord with more than 7,000 apartments: a prospective tenant gets a smart-lock key on their phone and views the apartment alone. We also built Goldfarb Connect, the residents’ door-access app, live since October 2024.

SelfTour IQ
Self-guided apartment tours
A self-guided tour platform for multifamily, student housing and build-to-rent operators: renters book a tour, unlock the doors with their phone and apply, all in one app. Walk In IQ reports it cut vacancy loss by 25% across Goldfarb Properties’ portfolio.

DOORe
Smart door lock and video doorbell
A fingerprint smart lock and HD video doorbell for homes and apartments, with time-limited virtual keys for family and guests. We built the mobile apps, the AWS backend and the device firmware. Read in press (CTech, June 2020).

FAQs on Real Estate Software Development
1. How much does custom real estate software development cost?
It depends mostly on the platforms involved and how much hardware the software touches. A focused tenant app costs far less than a portfolio-wide data platform. Integrations affect the cost most: an older property management system with a limited API or a mix of lock and sensor brands takes more work than a modern stack.
2. How long does it take to build?
A first release of a focused app or portal usually takes three to six months, including discovery and a pilot. Larger platforms are released in stages, so your team gets working software early and the rest follows.
3. Do you work with smart locks and building hardware?
Yes. We connect software to smart locks, access control, sensors and building management systems, and write device firmware when a product needs it. We can work with the hardware you already have or help you choose devices that fit the software.
4. Who owns the code?
You do. Every project starts with an NDA, and you receive the source code and documentation.
5. How do you handle data security and compliance?
We encrypt tenant data in transit and at rest by default, and payments go through PCI DSS compliant providers, so card details never touch your servers. Staff accounts get multi-factor sign-in and role-based access. We follow GDPR in Europe and US state privacy laws such as the CCPA.
6. Do you build MVPs for proptech startups?
Yes. We build MVPs for proptech startups and develop them into the full product once the idea is proven.
7. Can you modernize or extend real estate software we already run?
Yes. Most of our real estate work sits next to an existing platform. We can add a new module to a platform you rely on, or move an in-house system to a modern stack in stages so the business keeps running throughout.
8. Do you provide support after launch?
Yes. We stay on after release for monitoring and new features, and the team that built the product is the team that supports it. Support can scale up for a portfolio-wide rollout and back down once things are stable.
