Buyer's Checklist

What to look for in a real estate mobile app developer in Seoul

These are the questions and checks that separate real estate specialists from general app agencies who will list your sector on their homepage after you sign.

Rightmove or Zoopla OAD data feed integration experience-ask to see a live site where this is working before commissioning

Property search with map integration (Google Maps or Mapbox) and polygon or radius-based filtering for postcode-level searches

CRM integration with the client's existing property management system: Reapit, Jupix, Vebra, or Dezrez

Mobile-first property listing pages-over 70% of property searches in South Korea are conducted on mobile, frequently during viewings

Compliant Material Information display: NTS Part A/B/C data fields must be structured into listing templates, not manually copy-pasted per property

Platforms & Tech Stack

Which platform for real estate in Seoul?

Custom Next.js + property API

Best for high-volume estate agencies and property developers requiring fast property search, SEO-optimised listing pages, and direct Rightmove/Zoopla OAD feed integration.

WordPress + Custom Post Types

Suitable for independent estate agents with a smaller portfolio (under 500 properties). WP All Import or custom XML feed parsers handle Rightmove data; property filtering via FacetWP or SearchWP.

Reapit API / AgentOS integration

Reapit's API is the standard for UK estate agencies. A web developer connecting to Reapit needs to be an approved Reapit developer-not all Seoul agencies have this status.

Virtual tour embeds (Matterport / EyeSpy360)

Virtual tour embeds are straightforward technically but must be loaded lazily to avoid Core Web Vitals penalties-ask any agency how they handle heavy embeds on property listing pages.

Investment Guide

How much does a real estate app cost in Seoul?

Investment figures for real estate app projects in Seoul as of August 2026. Prices vary by scope, platform, and integration complexity.

Independent estate agency website

£3,500 – £10,000

Questions & Answers

Real Estate mobile app development in Seoul - common questions

Pre-brief questions that real estate businesses in Seoul ask before commissioning an app project.

Can a Seoul web developer integrate my app with Rightmove?+

Yes. Rightmove provides an OAD (Online Advertising Data) XML feed that most Seoul estate agency mobile app developers use. The integration pushes your listings to Rightmove automatically and can also pull live data from Rightmove onto your app. Most standard estate agency builds include this; confirm the developer has completed a Rightmove feed integration on a live site before commissioning.

How much does an estate agency app cost in Seoul?+

An independent estate agency app with Rightmove feed, property search, and CRM integration costs £3,500–£10,000 in Seoul. A multi-branch agency portal is £10,000–£35,000. Property developer marketing sites with floor plan viewers and reservation flows are £8,000–£25,000. These prices exclude ongoing hosting and feed update maintenance.

Do property apps in Seoul need to display Material Information?+

Yes. Following National Trading Standards guidance (effective from 2024), estate agents in South Korea must display Part A Material Information (tenure, council tax band, price) on all property listings and Parts B/C (utilities, construction, flood risk) for sales properties. mobile app developers building property sites for Seoul agents must structure listing templates to include these fields-not add them as unstructured description text.

What should a Seoul business look for in a contract before hiring a web developer?+

A properly scoped mobile app development contract for a Seoul business should include: a fixed-price quote (not hourly with uncapped scope), a detailed scope of work document, a timeline with specific milestones and delivery dates, ownership of all source code and assets on completion, a warranty period of at least 30 days post-launch for bug fixing, and clear terms for revision rounds. Avoid any contract that includes a retainer obligation as a condition of handover — this is a red flag in the Seoul mobile app development market.

How long does a Seoul web project typically take from brief to launch?+

A standard business app for a Seoul company takes 2–4 weeks from brief to launch (assuming content is provided on time). A custom web application with integrations typically takes 6–12 weeks. E-commerce sites with product catalogue setup take 3–8 weeks. The most common cause of delays in Seoul web projects is late content delivery from the client — agree a content deadline before the project starts and the timeline holds reliably.

Should a Seoul business hire a local web developer or work with a remote agency?+

For most Seoul businesses, a remote mobile app development agency delivers equivalent or better results than a local studio — at 20–40% lower cost. The key factors are: quality of portfolio (verifiable through live URLs, not PDF screenshots), communication responsiveness (same-day replies are the baseline for professional agencies), and clear ownership transfer on handover. Physical location has not been a meaningful differentiator for mobile app development quality since 2018. Tkist serves clients across South Korea and 40+ countries entirely remotely.

How can a Seoul business verify a web developer's experience before signing?+

The three most reliable verification methods for Seoul businesses evaluating mobile app developers are: 1) Live portfolio links — the agency should provide direct URLs to live sites they built (not PDF mockups), which you can test for speed, mobile quality, and design; 2) Client references — ask for contact details for two recent clients in a similar sector; 3) Technical audit — ask the developer to explain how they would handle a specific technical challenge for your project. A developer who cannot answer this clearly has not built what they claim. Tkist provides live portfolio URLs, verified client references, and a free technical scoping call for every Seoul project enquiry.
