Inmobi — AI-powered real estate platform

Overview

This case study details how KAUFAST built the InmobiMobi platform — a solution that could serve property buyers, sellers, and investors enabling borderless property investment across 5 European and Latin American markets, each with its own legal frameworks, tax structures, and language expectations. We built a full-stack multilingual real estate platform supporting 12 locales, country-specific property intelligence, and native mobile apps from a single shared codebase. The platform handles the full property lifecycle — from initial search with map-based exploration through to mortgage pre-qualification and transaction management — with country-specific workflows for each market.

The engagement covered the full product lifecycle — from multi-locale architecture and AI-powered data pipelines to native iOS and Android apps sharing a single codebase. Every component was designed to feel native in each market, adapting tax calculations, mortgage tools, and listing formats to local expectations. Cross-border mortgage calculators account for non-resident buyer restrictions, notary fees, and currency exchange margins specific to each jurisdiction.

The Challenge

Cross-border real estate is fragmented. A buyer in Germany looking at property in Spain faces language barriers, unfamiliar tax systems (ITP, AJD, Grunderwerbsteuer), and incompatible listing formats. Existing platforms either serve one country well or many countries poorly. InmobiMobi needed to feel native in every market — showing Stamp Duty calculators in the UK, Kaufnebenkosten breakdowns in Germany, Fideicomiso guidance in Mexico, and EPC energy certificates in Spain — all while maintaining a single deployable application. The technical challenge: zero hardcoded text across 25 translation namespaces, country-aware financial calculators, and hybrid mobile apps for iOS and Android.

A single codebase serves property seekers in 5 countries across 12 languages — from council tax bands in London to Fideicomiso zones in Cancun — with zero hardcoded text and sub-1.5s page loads.

Results

InmobiMobi's multi-market platform proved that a single codebase can deliver country-native experiences at scale. Within the first quarter, the platform served buyers and sellers across Spain, the UK, Germany, Mexico, and Colombia — each market with fully localized financial calculators, tax breakdowns, and listing formats. The hybrid mobile apps achieved 95% code sharing between web, iOS, and Android via Capacitor, reducing development time by more than half compared to native builds. Page load performance stayed under 1.5 seconds LCP even with property image galleries containing 20+ high-resolution photos, thanks to progressive image loading and Cloudflare R2 edge delivery. The AI-powered data pipelines process listings from multiple MLS feeds, normalizing formats and currencies across markets in real time.
