Eastern Peak is a property management software development company working with landlords and property managers, and with proptech teams building products for them. We cover leasing, rent, maintenance, owner reporting and building access, in one system or as additions to the one you run today.
Our property management software solutions are designed around the day-to-day work of running rental buildings. We deliver secure, scalable products for proptech startups entering the market and for established companies that need to modernize or extend their current systems.
Property Management Software We Build
Each module can run on its own or as part of a full rental property management platform.
Tenant portals and apps
Web and mobile tenant portals where residents pay rent, sign renewals, submit requests and get building notices. Most residents only ever see this part of your software, so it gets the most design attention.
Leasing and viewings
Listings, applications, screening checks and lease signing in one flow. Self-guided viewings let prospects tour an empty unit with a phone key and no agent on site.
Maintenance and vendors
Requests arrive with photos and go straight to the right technician or vendor. Your team sees what each open job costs and how long it has been waiting.
Rent and accounting
Rent collection, late fees, deposits and owner payouts, connected to your accounting system so nobody types the same numbers twice.
Owner and investor reporting
Statements and dashboards owners can open themselves, with occupancy and cash flow for each property. Fewer report requests land on your team at the end of the month.
Access control
Phone keys for residents and time-limited access for vendors and visitors, with a log of every door that opens. We build this layer down to the lock firmware when your hardware needs it.
Extend the System You Already Run
Add a module
Most property managers already run a core platform for accounting and leases, and replacing it is rarely the first step. We usually start by adding what it lacks, such as a better tenant app or a maintenance workflow, and connect the new module through the platform’s API.
Migrate in stages
When an in-house system has reached its limits, we move it to a modern stack one module at a time. Rent keeps coming in and leases keep renewing while the migration runs.
Property Management Software Projects

Goldfarb Properties
Tenant and resident apps
We built the tenant and resident apps for a New York landlord with more than 7,000 apartments. Prospective tenants view units alone with a phone key, and residents open lobby and apartment doors through Goldfarb Connect, live since October 2024.

SelfTour IQ
Self-guided tours for leasing teams
A leasing platform where renters book a self-guided tour, open the doors with their phone and apply in the same app, while agents follow each lead in a web portal. Walk In IQ reports it cut vacancy loss by 25% across Goldfarb Properties’ portfolio.
Technologies & Integrations
We build on a widely used, well-supported stack and connect your property management software to the systems around it.

AI for Property Management
We add AI where it saves your team hours of repeated work. A person signs off on anything that affects a tenant’s lease or money.
Renewal risk scoring
Flags residents who are likely to leave months before they give notice, based on payment history and service requests, so your team can act while there is still time.
Early arrears warning
Spots the payment patterns that usually come before arrears and suggests a payment plan before the balance grows.
Move-in and move-out inspections
Compares inspection photos from both ends of a tenancy and drafts the deposit deduction for any new damage, for a person to approve.
Vendor invoice checks
Matches each invoice against its work order and past prices for the same job, and holds anything unusual for review.
Our Property Management Software Development Process
Discovery
We look at how your team handles leasing and maintenance today, and where the current tools slow it down. You get a scope and a budget range before any build starts.
Design and prototype
Clickable prototypes of the tenant app and staff screens, tested with residents and site teams where possible.
Build and integrate
Two-week sprints with working demos. Connections to your accounting system and door hardware come first, because they carry the most risk.
Pilot
Launch in one building first. We fix what residents and staff run into before the rest of the portfolio moves over.
Rollout and support
Building-by-building rollout with data migration from the old system, then ongoing development as your portfolio grows.
A few quick questions show which kind of project yours most likely is.

FAQs on Property Management Software
1. How much does property management software development cost?
It depends on how many modules you need and how much the software has to connect to. A single tenant app costs a fraction of a full platform that replaces your current system. Older systems and door hardware add the most work.
2. How long does property management software development take?
A first module, such as a tenant portal or a maintenance app, usually goes live in a pilot building within a few months. A full platform is released in stages, so your team works with real software early.
3. Can you connect it to the property management system we already use?
Yes, as long as the system offers an API or a data export. We add the modules your platform lacks and keep it as the system of record, or move away from it in stages if that is the goal.
4. How do you move our data from the old system?
We map tenants, leases, balances and history into the new system and check test migrations with your team before switching over. Buildings move one at a time, so a problem never reaches the whole portfolio.
5. Will tenants get a mobile app or a web portal?
Usually both, running on one backend. Residents who only pay rent often prefer the web, while door access and maintenance photos work better in the app.
6. How do you keep tenant data secure?
Tenant data is encrypted in transit and at rest, and card payments go through PCI DSS compliant providers instead of your own servers. Each staff member sees only the properties and records their role needs. We build to GDPR in Europe and to US state privacy laws such as the CCPA.
7. Do you support the software after launch?
Yes. The team that built your platform stays on for updates and new modules, and support grows with the number of buildings you add.
