Real estate app development cost: prices by app type, MLS access, and support

A real estate app starts from $10,000 when it is a property search app for iOS and Android, with its own backend and one feed from a multiple listing service (MLS). A property management platform, with a web app for managers and a mobile app for tenants, starts from $30,000. A rental or sales marketplace starts from $20,000 for one platform. Each extra user role and MLS adds to the price, and MLS data fees are paid on top of the build.

This guide is for brokerages, property managers, and founders who want a budget before they ask for quotes. It covers prices by app type, the MLS step that can set the schedule, costs after launch, and ways to spend less.

Real estate app development cost by app type

Each price below is the starting price for the smallest working version of that type of app, and it is the whole price: design, project management, testing, the backend, the admin panel, and our integration work are in it. It covers one client platform, a web app or one iOS and Android app, and each extra platform starts from half of it. The timeline column gives the minimum; the project timeline comes with the estimate.

The property management row shows how extra platforms add up: the tenant app is a second platform on the same backend and admin panel, so it costs half of the first. For a fuller product, we estimated a real estate platform with client and partner accounts, an admin panel with a CRM, AI search, and subscriptions at about $43,000 and 14 weeks. Before the build, an optional analysis phase turns your idea into user flows and a scope document with a budget and timeline estimate. It costs $1,000-$2,000 and takes at least one week; a rough estimate is free.

MLS license fees and provider fees are paid to those providers and are not part of our price. Meeting each MLS's rules is part of the build: our engineers map every field and check the display rules.

What drives the cost of a real estate app

Five things move the price within each app type. Settle them before design starts: they decide how many apps, screens, and integrations the estimate has to cover.

• User roles: buyers, renters, agents, landlords, property managers, and your own staff each need their own screens and permissions. A new role can mean a new app or a web panel.
• Listing source: listings that owners or your staff add need an admin panel and moderation. Listings from an MLS need a data license and a feed integration.
• Map search: search by area, a drawn shape on the map, and nearby places need a maps provider, which bills by use.
• Money and documents: rent and deposit payments, e-signatures, and tenant screening go through providers. Our integration work with them is part of the build estimate, and each provider charges its own fees. The marketplace price already includes payments and identity checks.
• Platforms: a React Native app covers iOS and Android with one codebase, while native development means a separate app for each platform.

MLS and IDX access: the part of the budget outside the code

If your app shows listings from a multiple listing service (MLS), the local database through which brokers share their listings, the data license sets part of the cost and can set the schedule. You pay the MLS its own fees, and the approval can take longer than the integration takes to build.

MLSs owned and operated by REALTOR® associations must make their data available through the RESO Web API, a standard from the Real Estate Standards Organization. RESO does not provide listing data itself: you get access through the local MLS after you agree to its data use and licensing policies. RETS, the older standard, is deprecated and no longer supported by RESO, so a new integration should use the Web API.

IDX, short for Internet Data Exchange, is the policy that lets brokers show each other's listings on their websites and apps. NAR's IDX policy (Policy Statement 7.58) shapes the app in three ways:

• A broker controls the display: IDX listings must be under the actual and apparent control of an MLS participant, which is a broker. If your company is not a brokerage, you need a participating broker behind the app, or a different data license if the MLS offers one.
• Listing pages carry required details: the display must name the brokerage that runs it, and each listing must show the listing firm and its email or phone number. Short previews, such as thumbnails, can skip these details only when they link to a page that has them.
• The data stays fresh: displays fed by MLS downloads must be refreshed at least every 12 hours, so the backend needs a scheduled sync.

Under the same policy, the MLS must act on an IDX feed request within five business days, but a review of how the broker and the vendor will use the data can take longer. An app that covers areas served by different MLSs needs a license and an integration for each of them.

“Settle the MLS license before the build budget is spent, not while the code is being written. The license terms can change who may use the app and what it may show, and every screen built before you know them is one you might pay for twice.”

Evgeny Leonov, CTO at Ronas IT

The license and its fees stay between you and the MLS. On the app side, the optional analysis phase before the build maps user flows for search and listing pages and assesses whether the feed integration is technically feasible.

Real estate app features by role

Features follow the roles. Plan the first version around the buyer or renter side and the side that supplies the listings, and add the other roles in later releases.

Buyers and renters

• Search: filters by price, bedrooms, property type, and area, and a map where the user can draw the area.
• Listing page: photos, details, the location on the map, and the listing firm's contacts where the MLS requires them.
• Saved searches: favorites and an alert when a new listing matches a saved search.
• Contact: a tour request or a chat with the agent or the landlord.

Agents and landlords

• Leads: every request with the listing it came from.
• Own listings: adding and editing listings that do not come from an MLS.
• Tours and applications: a calendar of tours and, for rentals, applications from tenants.

Property managers and tenants

• Leases and rent: tenants and leases in one place, rent collected online, and reminders before the due date.
• Maintenance requests: a tenant reports a problem with photos and follows its status.
• Documents: leases and notices signed online and stored with the property.

Admin panel

• Control: users and roles, listing moderation, and the content of the app.
• Reports: leads, listings, and payments over any period.

Costs after launch

After launch you pay for support, for new features, and for the third-party services the app uses. The support price depends on what runs in production. The monthly fee pays for an engineer who works with AI agents to watch the app, fix problems, and ship updates.

• Support for one app, from $1,000 per month: a search app with its backend once it is live. It covers monitoring for availability issues, bug fixes, compatibility updates for new iOS and Android versions, and the changes Apple and Google require to keep the app in their stores.
• Support for the whole system, from $2,000 per month: several apps on one backend, such as a manager web app and a tenant app, with the same monitoring, fixes, and updates across all of them. New features are priced as development work.
• DevOps and hosting, from $200 per month: environments, the release pipeline, and monitoring for one project. The cloud bill itself comes to you from the provider.

Third-party services bill you directly:

• MLS data: fees set by each MLS.
• Maps: Google Maps Platform charges for each billable event above a free monthly amount for each service. The Dynamic Maps service, for example, gives 10,000 map loads per month for free, then costs $7.00 per 1,000 loads, with lower rates at higher volumes.
• App stores: the Apple Developer Program costs $99 per membership year, and Google Play charges a one-time registration fee of $25.
• Hosting, payments, and e-signatures: billed by their providers. The app runs in your own cloud account, so hosting bills come to you directly.

Ready-made software or a custom app?

Buy ready-made software when your process is standard. Build a custom app when the software is your product, or when your process does not fit the tools on the market.

• A brokerage website with listings: if you only need listing search on your website, compare the prices of ready-made IDX products with the cost of a custom build.
• Property management with standard leases: check whether off-the-shelf property management software already handles your rent collection, maintenance requests, and accounting.
• A product for other people: a startup that sells the app, a new kind of marketplace, or a workflow no tool supports needs its own data model and integrations, and these cases call for custom real estate software development.

If a ready-made tool fits your case, we will say so and suggest it instead of a custom build.

UK Retreats: one mobile-first web app instead of a native app and a website

UK Retreats already had a database of unusual holiday stays across the UK when it asked us to build UKR Club, a community for property owners and their guests with access by subscription and no MLS feed.

The audience research showed that UK Retreats customers would rather use a mobile device than a laptop. To meet the client's budget, we dropped the plan for a native mobile app plus a website and built one mobile-first web app instead, so the client paid for one codebase rather than two. The web app had a map of stays on the home page and an admin panel for uploading new stays with photos, descriptions, locations, and tags. The MVP was ready within 3 months.

• Web app and landing page: React for the web app, and Next.js for the landing page that we built after the web app to bring in subscribers.
• Backend and admin panel: Laravel, with Laravel Nova for the admin panel.
• Integrations: Stripe for subscriptions, Google Maps with the Geocoding API to place each stay on the map, and Mailgun for email.

How to lower the cost of a real estate app

Start with one area, one codebase, and ready-made services, then spend the rest of the budget where users show they need it.

• One MLS and one area first: each extra MLS adds a license, fees, and an integration.
• One codebase: a React Native app that runs on both iOS and Android, or a mobile-first web app, as in the UKR Club project.
• Providers for payments, e-signatures, and screening: an integration costs less than building and maintaining these parts yourself.
• 3D tours from a tour provider: embed the provider's viewer instead of building your own.
• AI features in a later release: each AI feature added to a live app, such as a chatbot or listing recommendations, starts from $3,000, so add them once you know what users ask for.

“In a first release, I would put the budget into search and alerts, because that is where buyers spend their time. A simple admin panel is enough at the start. Once we see which filters people use, we know where the next budget should go.”

Alexander Storozhevsky, Lead developer at Ronas IT

The tech stack we start from

For a new build, our default is one React Native codebase for iOS and Android and one backend that owns the listings and the users.

• Mobile apps: React Native with Expo.
• Web app: Next.js or plain React.
• Admin panel: Laravel Backpack by default, or Laravel Nova.
• Backend: Laravel with PostgreSQL.
• MLS feed: scheduled jobs in the backend pull updates through the RESO Web API, at least as often as your MLS's display rules require. We confirm the field mapping on a sample of your feed.
• Chat and live updates: Laravel Reverb as the WebSocket server, so a new message reaches the agent without a page refresh.
• Maps and payments: providers such as Google Maps Platform and Stripe.

What to do next

1. Pick the app type and the first area. The cost table gives the starting price of each type.
2. Ask your MLS three questions. What does its data license cost, how long does approval take, and does your app need a participating broker?
3. Build the budget. Take the build price of your app type for each platform you need, then add monthly support, DevOps and hosting after launch, and the third-party fees.

With these answers, an estimate describes your app instead of a generic one, and the first version stays small enough to launch in one area and learn from real users.

Tell us which type of app you need, who its users are, and which MLS you plan to use, and we will send you a rough estimate for that scope.
