Harmelo Registry: Live For REITs · Asset Managers · Developers
For multifamily owners, operators, and REITs

Fewer emergency calls. Safer buildings. Capital you can plan.

If you own or run rental and multifamily buildings, the building systems inside them are where the surprise costs live. Harmelo keeps every one of those systems on the record across all your properties, so you cut emergency breakdowns, keep tenants safe and comfortable, and budget replacements before they blindside you. The same record scales up to REIT and institutional disclosure when you need it.

What a breakdown really costs
Replacing a system after it fails runs three to five times the cost of the same job planned ahead. In a rental building it also means tenants with no heat or hot water while you scramble for a part.

Return on planned maintenance
Every dollar spent on planned maintenance offsets roughly four to five in later emergency cost. Capturing that swing means knowing which systems are aging, and when, before they go.

Any age
Works on the equipment you already have
You do not need new installs to start. Harmelo works on the furnaces, boilers, rooftop units, and energy systems already in your buildings, and the record only gets more valuable as it grows.

Why operators run on it

Run your buildings on what's actually happening inside them. Not guesswork.

Most rental and multifamily operators plan around equipment they cannot really see, so replacements arrive as emergencies and reserve numbers are half guess. Harmelo puts every building system on one record, and turns it into the four things that actually move the needle in a rental building.

Less downtime
Catch it before it quits
See which systems are aging or drifting out of spec and get ahead of them. Fewer no-heat calls, fewer emergency truck rolls, fewer tenants without hot water while you chase down a part.
Tenant safety and satisfaction
Comfortable, safe, renewing
Every system's condition and signed service history in one place, including the life-safety equipment you are accountable for. Warm, safe tenants renew. Cold ones with a dead furnace do not.
Capital budgets
A number you can defend
See what is aging across every building and what it will cost to replace, so your reserve and capital plan is a forecast you can take to ownership or a lender, not a guess pulled off an age chart.
Buy the right equipment
Know what actually held up
Watch how each unit performs over its real life. When it is time to replace, you know which makes and models lasted in your buildings and which did not, so the next purchase is the smart one.
The Harmelo operator console showing a multifamily portfolio with condition, properties, systems, and what needs attention
Your whole portfolio in one console. Condition, capital, and what needs attention today.
In the console

See it the way your team will. Not a slide about it.

This is the console operators actually run their portfolio in. Contractors log their work in the field for free and it flows straight into the record, and it stays with the building even when management changes or a contractor rotates out. Nothing resets at a sale or a handover.

Capital planning

Reactive replacement turned into a planned number, by year, so the next budget is a forecast instead of a fire drill.

Condition at a glance

Every system scored across every building, with the ones drifting toward end of life surfaced first.

Positioning

It's not a property management system. It's the data layer beneath one.

Your PMS tracks leases, tenants, and work orders. Your CMMS schedules tasks. Harmelo doesn't replace either, it sits underneath them as the neutral, persistent record of what's physically installed, how it's aging, and what it will cost.

The registry is the verified source of truth your existing systems read from, and the record that survives when they're swapped, when operators change, and when the building changes hands.

Works alongside your stack

Identity attaches during normal install and service activity. No rip-and-replace, no new operator workflow, no disruption to your contractor network.

Neutral and portable

The record is tied to the asset, not to any one operator or platform. It moves with the building across every transition, which is exactly why it stays reliable.

Built for capital decisions

Where a PMS answers "what's leased," the registry answers "what do we own, how is it aging, and when will it need capital", the questions reserve studies and the Infrastructure Disclosure Report actually turn on.

Working together

Set up around your portfolio. Not off a shelf.

Every portfolio is different: residential, commercial, mixed-use, industrial, each with its own mix of building systems, regulations, and capital cycles. We work directly with your team to fit Harmelo to how your portfolio actually runs, and we stay in it with you after go-live. Here is what a partnership includes.

Ask Elo

An assistant that knows your portfolio

Every account includes Elo, our assistant. Ask it why a system is flagged, what a fix involves, or how to sequence your capital, and get a straight answer without digging through the record.

Onboarding

Set up with you

We help you get every building system across your portfolio onto the registry, so you start from a complete picture instead of a blank page.

Your team

People who stay

A dedicated account team for your portfolio operations, with regular reviews so the registry keeps pace with your buildings.

Your process

Templates or your own

Use our checklist templates for thorough service, or build your own field records tailored to how your crews already work.

Who it is for

Built first for the people who run rental buildings.

Multifamily and rental operators are where Harmelo pays off fastest, and the same record scales up to developers, long-term holds, and REITs when you need disclosure and diligence. The framing changes, the verified record underneath does not.

Rental Portfolio Operators
Capital planning
Track mechanical and energy systems across buildings, monitor aging equipment, and plan capital replacements across the portfolio. Reactive maintenance gives way to forecastable, board-defensible capital plans.
Mixed-Ownership Developers
Transaction readiness
Transferable infrastructure records move with each unit, improving buyer confidence and reducing warranty disputes whether you rent, sell, or do both. Continuity survives every ownership transition.
Long-Term Hold & Institutional
Reserve forecasting
For multi-decade ownership horizons, predictability is everything. The registry is the data layer that makes long-horizon reserve and capital planning reliable, auditable, and defensible.
REITs & Asset Managers
ESG & disclosure
Surface which systems are aging, which contractors perform, and which manufacturers deliver, across the whole portfolio. ESG and disclosure reporting reference verified operating data, not estimates.

What Harmelo Is Not

Honest about what we do and don't do.

Harmelo is a registry. It is not an appraisal firm, an audit service, a regulatory filer, or a substitute for the professional reports and regulatory frameworks that institutional portfolio operators work within.

Permits & municipal compliance

We do not pull permits, contact municipalities about permits, pay for permits, or verify that a permit is on file with the relevant authority. Permit numbers attached to the registry record reflect what your contractor entered, verification with local authorities is the responsibility of the permit-holder.

Inspection, certification & workmanship

We do not perform, supervise, certify, or verify the quality of any work performed. We are not licensed contractors, engineers, building inspectors, or code-compliance auditors. The registry verifies that the contractor signing a record is a real, credentialed, insured tradesperson; the workmanship itself is between the operator and the contractor.

Service, dispatch & warranties

We do not perform, schedule, dispatch, quote, or charge for any service work. We do not issue, manage, transfer, or honor warranties. Manufacturer warranties and labour warranties are issued by the manufacturer or contractor and stay with them. Warranty documents on the record are stored for reference; we don't administer or enforce them.

Appraisals, audits & valuations

Harmelo does not perform property appraisals, financial audits, or asset valuations. Registry data provides verified condition information that can inform these processes; the appraisals, audits, and valuations themselves are produced by licensed professionals operating under their own regulatory frameworks. The registry is supplemental to professional financial reporting, not a substitute for it.

Regulatory & compliance reporting

We do not file or certify regulatory reports, securities filings, ESG disclosures, climate reporting, tax filings, or other regulated submissions. Registry data may inform these reports, but the certification, attestation, and submission of regulated reports is the operator's responsibility under their own regulatory obligations.

Transaction execution

We do not execute, advise on, or facilitate transactions, acquisitions, dispositions, refinancings, or restructurings. Registry records support diligence processes; the transactions themselves are run by the operator's investment, legal, and advisory teams under their own engagement letters and fiduciary frameworks.

The registry is the record, not a substitute for the professional judgment, regulatory processes, or contractual relationships that govern your work. If something on a record needs to be verified, corrected, or disputed, that conversation happens with the contractor who signed it or the authority responsible for the underlying process. Our role is to keep the record straight, structured, and accessible to the parties who need it.
