RentalOS is the yield-governance layer for rental portfolios. It runs every lease renewal against RERA statutory caps, models the expected value of each strategy, and books the result to a tamper-proof ledger. Cross-owner, examiner-ready, and paid on the yield it protects — not a per-seat rental.
Dubai portfolio operators are forced to choose between heavyweight foreign property-management suites that have never heard of a RERA rent cap or an Ejari record, generic SaaS that treats a renewal as a calendar reminder, or fragile spreadsheets that fall apart at the first Rental Dispute Centre challenge. RentalOS is purpose-built for the middle — real statutory compliance and a real yield model, right-sized for a multi-owner portfolio and owned outright rather than rented.
Not a generic PMS with a renewals bolt-on. Every module is shaped around how governed, cross-owner rental works here.
Validate every proposed rent against the Decree No. 43 of 2013 sliding scale before it reaches a tenant. Each evaluation issues a tamper-evident certificate, auditable by hash.
Model renewal strategies on Expected-Value arithmetic — weighing uplift against vacancy cost and owner-mandate constraints — so every decision is the profit-maximising one, not a guess.
A rolling 30/60/90/120-day pipeline with critical statutory-notice countdowns and tenant payment ratings — so no renewal window and no legal deadline is ever missed.
Draft bilingual EN/AR legal notices in a slot-locking editor, verify them, and gate dispatch behind mandatory landlord sign-off — statutory-form correct, every time.
Configure strategic owner mandates, compile board-ready report packages, and give each owner a partitioned portal that shows only their assets — cross-owner by design.
A tamper-proof, cryptographically traceable outcome-attribution ledger records every protected AED of yield, reconciles billing to the cent, and exports on demand.
Monitor live PMS sync connectors, schedule Ejari ingest, and force rent-index snapshot updates — the Dubai data stack wired in and observable in one console.
Tenants review a RERA-certified renewal proposal, verify the compliance certificate themselves, and execute the contract by DocuSign or PandaDoc — installable, no app store.
Distinct workspaces for portfolio director, CFO, asset manager, compliance officer, leasing agent, owner-principal, ops and tenant — each scoped to exactly what its role may see and do.
When a compliance exception is warranted, a director authorizes it with a PIN — and the override, its reason and its actor are written immutably to the record. Nothing off the books.
Not mockups. Every screen below is live in the RentalOS demo environment today.
The RERA Compliance Engine validates each proposed rent against the Decree 43 sliding scale and issues a tamper-evident certificate. A Rental Dispute Centre challenge becomes a hash lookup, not a scramble through email.

Renewal Radar rolls every lease into 30/60/90/120-day windows with critical notice countdowns and tenant payment ratings — so the team works the pipeline by priority instead of reacting to whatever expired yesterday.

The Integration Management Hub keeps live PMS connectors, Ejari ingest schedules and rent-index snapshots in one observable console — so the numbers a renewal is priced on are always the current, official ones.

A clean, installable PWA where tenants see their proposed terms, verify the RERA compliance certificate for themselves, and sign — building trust into the transaction instead of a PDF attached to an email.

Two walkthroughs — one from the tenant's seat, one from the back office.
Tenant experience
The full tenant renewal journey: sign in, review the proposed terms, verify the RERA compliance certificate, and execute the contract in seconds. Mobile PWA, no app store needed.
Platform walkthrough
Director, compliance, leasing, owner and finance. Governed workspaces, the RERA engine, Expected-Value yield modelling, bilingual notices and a tamper-proof outcome ledger — all wired in from day one.

Property managers, multi-owner asset managers and institutional landlords get bank-grade governance without a bank-grade budget or headcount.
Pre-built RERA compliance and Ejari integration mean you configure mandates and launch — instead of funding a multi-year property-management migration.
RERA caps, statutory notices and sign-off gates are wired into the workflow — so you clear a Rental Dispute Centre challenge because the system never let you off the rails.
From one building to a cross-owner portfolio with mandates, partitioned portals and community-level analytics — one governance layer grows with you.
RentalOS is not SaaS. Under a source-available license you receive a copy of the source code, brand it as your own, deploy it wherever you choose, and keep full control of your data and your roadmap.
You receive the complete source under a perpetual license. Read every line, audit it, and never be held hostage to a vendor's roadmap or release cadence.
White-label from the ground up — your name, logo, colors and domain across the tenant app, owner portals and staff console. Ship it to market as your product, not ours.
Your cloud, your on-prem data center, your region of choice. No mandatory vendor cloud, no per-unit metering, no usage caps that throttle portfolio growth.
Tenant PII, owner records and lease data sit in infrastructure you own — making UAE data-residency obligations far simpler to demonstrate to owners and regulators alike.
Modify and extend the platform for your own mandates and workflows. The code is yours to evolve — by your team or ours — as the portfolio grows.
A one-time license to the delivered version, yours to run indefinitely. No subscription that can be switched off, no renewal leverage held over you.
Governed renewals, RERA compliance and bilingual notices across every managed building, out of the box.
Owner mandates, partitioned portals and cross-owner reporting — govern many owners from one layer.
Expected-Value yield modelling and a tamper-proof outcome ledger for board-grade accountability.
A tenant renewal PWA and e-signature rails to run a modern, trusted leasing operation at scale.
