Custom real estate software: portfolio management, tenant portals and data-driven asset management

From rent collection to sustainability reporting, bring your property processes together in a platform that scales with your portfolio. Real estate firms that unify administration, maintenance and yield analysis in one system often save dozens of hours monthly on coordination.

The real estate industry is rapidly evolving under pressure from multiple forces: tightening regulations around energy efficiency (EPC ratings, Paris Agreement targets), tenant protection legislation, environmental reporting requirements and the growing expectation from both tenants and investors for digital transparency. Housing markets across Europe remain structurally tight, while construction costs outpace rental income growth for many landlords. Institutional investors demand increasingly granular ESG reporting (GRESB, CRREM, SFDR Article 8/9), and housing associations face stricter assessments from regulators on both financial and social performance. The shift from property as a purely financial asset to property as a service requires a fundamentally different digital infrastructure, one that places the tenant at the centre while reducing the administrative burden on property managers. Investors, developers, housing associations and property managers frequently operate with a mix of spreadsheets, disconnected property management tools and manual communication. This fragmentation leads to delays in rent collection, maintenance requests lost in email inboxes and reports that fail to meet the standards demanded by institutional investors or regulatory bodies. Custom software integrates portfolio management, tenant communication, maintenance workflows and financial reporting into a platform that scales with the size of your holdings. By connecting with land registries, property valuations, energy label databases and accounting packages, a single source of truth emerges for both operational teams and board-level decision makers. MG Software builds real estate platforms that automate processes and deliver real-time insights into yield, sustainability progress and tenant service levels, enabling data-driven decisions rather than gut-feel management.

Pain points

  • Fragmented administration across spreadsheets, standalone property management tools and email, resulting in a lack of overview and errors in rent collection, lease renewals and maintenance allocation
  • Absence of a centralised tenant portal where residents can report maintenance, view rent status and download documents, leading to an overloaded service desk and low tenant satisfaction scores
  • Complex reporting requirements from investors, auditors and regulators (including ISAE 3402 for property managers) that are compiled manually and prone to errors
  • Increasing regulatory pressure around sustainability (energy labels, Paris Proof targets), tenant protection legislation and environmental compliance requiring additional registration and transparency
  • Maintenance cycles managed reactively rather than preventively, driving up costs and frustrating tenants with long turnaround times for repairs
  • Limited visibility into actual yield per property, complex or portfolio because financial and operational data reside in separate systems that are not reconciled automatically
  • Difficult integration with external systems such as land registries, property valuations, market data providers and accounting packages like Xero, QuickBooks or Sage
  • Institutional investors and housing regulators demanding standardised ESG reporting (GRESB, CRREM) that requires data aggregation from multiple operational sources

Our solutions

  • Centralised real estate platform combining portfolio management, lease contracts, maintenance and financial reporting in a single application with role-based access for property managers, investors and maintenance teams
  • Tenant portal with self-service functionality: maintenance reporting with photo upload, rent status overview, document downloads, automatic status updates and in-portal communication replacing phone calls and emails
  • Preventive maintenance management with planning dashboards, automated reminders for periodic servicing (boilers, lifts, roofs) and contractor portal integration for quotes and sign-off
  • Automated financial reporting including rent collection overviews, yield calculations per property or complex, rent indexation and automatic export to accounting packages
  • Sustainability dashboard with energy label registration, energy consumption monitoring, CO2 footprint per property and roadmap to Paris Proof or target label, including reporting for GRESB, CRREM or internal ESG frameworks
  • Integrations with land registries, property valuations, market data and building registers for automated property registration and market value updates without manual data entry
  • ESG and regulatory reporting module with built-in validation rules, data aggregation across the portfolio and export functionality meeting institutional investor and housing authority standards

Benefits

  • Dozens of hours saved monthly on administration as rent collection, contract management, maintenance and reporting are driven from a single system without duplicate data entry
  • Higher tenant satisfaction through self-service capabilities, faster maintenance resolution and transparent communication via the tenant portal
  • Real-time visibility into yield per property, complex and portfolio, enabling investors and managers to make data-driven decisions about acquisitions, disposals, renovations and pricing strategy
  • Lower maintenance costs through the shift from reactive to preventive maintenance, with automated schedules and timely flagging of deferred works
  • Full compliance with reporting obligations to investors, regulators and auditors through automated exports and built-in validation rules
  • Acceleration of sustainability targets through centralised insight into energy labels, consumption data and the route to Paris Proof per property

Our approach

We start by mapping your property structure, lease types and financial reporting cadence: which reports must be delivered monthly, quarterly or annually? Which systems are authoritative for which data? From there we build a prioritised roadmap, beginning with the process that consumes the most time (typically rent collection or maintenance coordination). Every two weeks we deliver working software tested by property management teams using real property data and lease contracts. We involve tenants early through a pilot with a limited set of properties, ensuring usability is proven by real feedback rather than assumptions. Integrations with land registries, valuations and accounting packages are added incrementally, with careful attention to data quality and deduplication of property records. Migration support is included: we assist in transferring historical data from legacy systems so you do not have to start from scratch. Post go-live we monitor performance and provide ongoing maintenance so the platform scales with your growing portfolio.

How to measure success?

Key metrics include maintenance request turnaround time (from report to completion, broken down by category and priority), collection rate and average collection period in days, percentage of tenants actively using the portal within the first quarter after launch, financial report accuracy measured by the number of corrections after delivery to auditors or investors, yield insight per property, complex and portfolio versus internal benchmark and market average, occupancy rate and average void period between tenancies, and progress on the sustainability roadmap (percentage of properties at target label per year). We also track tenant service levels: average response time to reports, first-time fix rate and NPS score per quarter. Dashboards are accessible to operational teams, management and investors, with automated monthly and quarterly reports.

Frequently asked questions

Yes. The platform is modular: investors use portfolio and yield modules, while housing associations additionally access regulatory reporting, housing authority integrations and social management modules. The core (properties, contracts, maintenance, tenant portal) is shared across both segments. Each user role sees only the dashboards and data relevant to their responsibilities, so a maintenance coordinator is not overwhelmed by financial reports and an investor is not distracted by individual repair tickets.
We build automated connections that retrieve cadastral data, property valuations and building register information and synchronise them with your property database. Changes in ownership, surface areas or zoning designations are flagged automatically. The synchronisation runs on configurable schedules and can also be triggered manually, for example during an acquisition or property split. Discrepancies between your internal records and external sources are highlighted for manual review, ensuring data integrity across the portfolio.
Yes. The sustainability dashboard records energy labels per property, monitors consumption based on smart meter data or manual input and calculates the CO2 footprint per property and per portfolio. You can create improvement roadmaps to target labels or Paris Proof standards with indicative measure costs and payback periods. Reporting in line with GRESB, CRREM or internal ESG frameworks is generated from the same underlying dataset, ensuring consistency across all stakeholder reports.
A core platform with property management, tenant portal and maintenance starts from around 25,000 euros. A fully integrated platform with financial reporting, external data connections and sustainability dashboards ranges from 60,000 to 200,000 euros, depending on portfolio size and the complexity of lease structures. We always provide a transparent quote based on a joint assessment of your property structure and operational workflows, so you know upfront which investment yields which time savings.
Yes. Tenants submit maintenance requests via a user-friendly form with photo upload and category selection. The request is automatically routed to the appropriate maintenance team based on property location, fault type and SLA agreements. Tenants receive status updates at each step via the portal and optionally by email or push notification, so they always know where their request stands without needing to call the management office.
A first working version with property management, lease contracts and maintenance is typically ready within 10 to 14 weeks. The full platform including financial integrations, tenant portal and reporting modules takes 5 to 9 months, depending on the number of property types, external connections and lease structure complexity. We prefer to launch the first version with a pilot group of property managers on a limited set of assets, so the system is validated before broader rollout across the portfolio.
Yes. The data model supports different property types (residential, office, retail, industrial, logistics, parking) with specific lease forms, indexation rules and reporting per segment. You manage the entire portfolio from a single platform with segmentation at any level you require: by geography, asset class, fund or any custom grouping. Consolidated and per-segment reports are generated from the same dataset, so there is no risk of misaligned numbers between operational and investor views.
