Eastern Peak is a real estate portal development company working with brokerages and property companies, and with proptech startups building listing businesses of their own. Our real estate website development covers the whole platform: the public site buyers and renters search on, plus the admin side and data feeds your team relies on.
Our real estate web portal development solutions are designed around how people search for a home and how agents and landlords keep their listings up to date. We build them for startups launching a new marketplace, and for brokerages that have outgrown a template site.
Real Estate Portals We Build
Each portal is shaped by who lists on it and who comes to search.
Listing marketplaces
Real estate marketplaces where agents and private owners post homes for sale or rent, and buyers search all of them in one place. Duplicates are merged, so each home shows up once.
Rental listing portals
For landlords and operators who list their own buildings. Renters filter by budget and move-in date, then apply or book a viewing straight from the listing. Once the lease is signed, the tenant moves over to your property management software.
Brokerage and agent websites
Real estate websites with IDX search across the whole MLS on your own domain, and your agents’ listings shown first. Every enquiry lands in the right agent’s CRM.
Commercial property portals
Office and industrial space searchable by size and availability date, with floor plans and brochures on each listing. Brokers get enquiries with the tenant’s requirements already filled in.
Portal modernization
We rebuild portals that run on a website builder or an IDX plugin, and redirect every old URL to its new page. We also extend existing custom platforms and add a property listing app that runs on the same API.
Real Estate Portal Features
Most portals launch with a few of these and add the rest as listings and users grow.
- Map search: draw an area on the map or search by commute time
- Saved homes and alerts: a message the moment a match is listed or its price drops
- Tour booking: pick a time on the listing page, in person or by video
- Cost calculators: monthly mortgage or rent shown next to the price
- Languages and currencies: for portals that list homes in more than one country
- Listing editor: photos, video, floor plans and 3D tours in one form
- Bulk import: inventory pulled from a CRM or feed file on a schedule
- Lead inbox: messages and tour requests from every listing in one place
- Listing stats: views and enquiries for each property
- Listing moderation: approve or reject new listings before they go live
- Users and roles: separate access for agents, landlords, brokerages and staff
- Verification: agent credentials and landlord ownership documents checked at sign-up
- Review moderation: ratings of agents and buildings, held for review when flagged
- Admin dashboard: leads and revenue by city
- Featured listings: paid placement at the top of search results
- Agent subscriptions: monthly plans with a set number of active listings
- Pay per lead: agents pay for each enquiry they receive
- Advertising: ad slots for mortgage lenders and moving companies
Our PropTech Projects
Goldfarb Properties
Apartment search with a phone key
Goldfarb Properties, a New York landlord with more than 7,000 apartments, wanted renters to view the apartments they found without waiting for an agent. In the app we built, a renter picks an apartment, gets a generated key for its smart lock and views it on their own schedule.
SelfTour IQ
Tours booked from the listing
Renters schedule a SelfTour in the app and unlock the doors themselves when they arrive, while leasing agents follow each lead in a web portal. Walk In IQ reports the platform cut vacancy loss by 25% and staffing costs by 35% across Goldfarb Properties’ portfolio.
Technologies & Integrations
We build portals on a stack that handles large inventories and fast search, and connect them to the services around them.

AI in Real Estate Portals
We add AI where buyers search and agents handle leads, and keep search results within fair housing rules.
Search in plain language
A search box that understands “three bedrooms near a good school under $600k”. The portal reads the request, sets the filters itself and keeps them editable, so buyers can still adjust the price or area.
Home value estimates
Owners and agents see a likely price range for any address and how long similar homes nearby took to sell, based on your listing history and recent local sales.
Listing assistant
Answers questions about a listing at any hour and books viewings. Each lead goes to the agent who covers that area, with a short summary of what the person asked.
Duplicate and scam detection
Compares each new listing with the inventory by photo and address, and holds likely copies and scams for a moderator.
Our Real Estate Portal Development Process
Discovery
We define who will post listings and who will search them, and scope what the first version needs. You get a scope and a budget range before the build starts.
Design and prototype
Clickable designs of the search and listing pages, which buyers and agents try out before we write any code.
Build and integrate
Development in two-week sprints, with a working version of the portal after each one. Data feeds go in early, since partner approvals can take weeks.
Launch
We open the portal in one market or to a first group of agents, fix what they report, then roll it out wider.
Support and growth
New markets and features as the portal grows, and an alert the moment a listing feed stops updating.

REVIEWS
We wanted to enhance our shipping solutions by migrating our desktop-based platform and its users to a new web application. Good KPIs met our expectations, generating plans for future collaboration with Eastern Peak.
interview on Clutch
We had a development challenge, as well as a business one. We needed quality people quickly, so we decided to approach Eastern Peak. The results were excellent and we were able to exploit the full potential of the IoT.
interview on Clutch
Eastern Peak assumed responsibility for their results and never tried to deflect it. They stood behind their promises and were very pragmatic. We have received input on app development as well as on our general business model, which helped a lot.
interview on Clutch
We needed to find people who were experienced specifically with startup schedules. Most of the people I’ve worked with had experience of five or six startups, and they’re in their mid-20s. These guys have a good reputation, and I just got very lucky to work with them.
interview on Clutch
They gave me the knowledge, expertise, and experience I needed to launch everything from the beginning and to support it further. They’re like a partner in terms of thinking and creating new concepts, new features, and new ideas.

FAQs on Real Estate Portal Development
1. How much does real estate portal development cost?
The cost of real estate portal development depends on the project. The main factors include where the listings come from, how many markets the portal serves, the features it needs and whether you’re moving from an existing site.
2. How long does it take to build a real estate portal?
A first version for one market usually goes live within a few months. MLS approval runs on the board’s own schedule, so we start that paperwork in the first week of the project.
3. Can you build a website like Zillow?
Yes, in the sense most clients mean: map search across a large inventory, with leads routed to the right agent. Most portals start with one market and the feeds that cover it, then add markets once the first one brings in steady traffic.
4. Can we move from an IDX plugin without losing our rankings?
Yes. We redirect every old URL to its new page and keep the titles of pages that already rank. Rankings can move for a few weeks after any migration, and we watch them closely through that period.
5. Do you support the portal after launch?
Yes. The team that built it stays on to keep the MLS connections running and to add markets and features as the portal grows.
