Real Estate Business Information Model
A structured inventory of the business data entities a real estate business runs on — property, building, unit, lease, tenant, owner entity, work order — in editable Word, with a data modeling guide.
About This Business Information Model
The Building Is Physical. The Asset Is Legal. They Are Not the Same Thing.
Real Estate Business Information Model is a structured inventory of the business data entities a real estate business runs on — property, building, unit, space, lease, tenant, owner entity, work order, valuation — organized into foundational, transactional and informational layers, in an editable Word document with a guide to business data modeling.
Real estate data confuses physical and legal structure almost everywhere. A property is a physical thing with buildings and units; an asset is a legal thing owned by an entity, financed by a loan, and reported to an investor. One property can be several assets, and one asset can be several properties.
The lease side compounds it. A lease is between a tenant and an owner entity, covers one or more spaces, may include options, escalations and recovery terms, and is amended over its life. Systems that treat lease as a property attribute cannot answer questions about a tenant across a portfolio.
This model separates physical, legal and contractual structure. It is a business information model rather than a database design — it states what the business means, which is the layer that determines what can be rolled up later.
The Distinctions This Is Meant to Make
Three modeling decisions that determine what a portfolio can report on.
Property, asset, or entity? Physical structure, investment structure and legal ownership rarely align one to one. Modeling them as one hierarchy is why portfolio and entity reporting have to be reconciled by hand.
Unit, space, or suite? Leasable area is divided differently by leasing, by facilities and by accounting. A demised space that spans two units is ordinary and breaks a single-hierarchy model.
Who is the tenant? The signing legal entity, the guarantor, the occupying business and the parent covenant can be four parties. Credit exposure across a portfolio requires all of them.
Why This Matters Now
Financing conditions and reporting demands both reward portfolios that can roll up cleanly.
Lenders and Investors Ask for Roll-Ups
Rent rolls, exposure by tenant covenant, and NOI by asset all require the physical, legal and contractual structures to be separable. Portfolios that conflated them produce these slowly.
System Consolidation Needs a Common Vocabulary
Property management, accounting and asset management platforms each impose a structure. Mapping between them requires an owner-defined model to map to.
Lease Accounting Made the Contract Entity Load-Bearing
Accounting treatment now depends on lease terms as data rather than as document text. That only works if the lease is an entity with structure.

Who This Is Built For
This model pairs with the Real Estate Capability Model, which states what the business does; the information model states what it does it to. Neither substitutes for the other.
How to Put It to Work
- Separate physical structure, legal ownership and investment structure into distinct hierarchies.
- Model the lease as an entity with terms rather than as a document attached to a unit.
- Capture tenant, guarantor and covenant parent so exposure can be seen across the portfolio.
- Use it as the owner-defined target when mapping property management and accounting systems.
Where Owners and Managers Typically Start
Producing a portfolio roll-up that ties. Separate the three hierarchies rather than reconciling them each reporting period.
Answering tenant exposure questions. Model covenant and guarantor so exposure can be aggregated at all.
Consolidating property systems. Map each platform to an owner-defined model rather than to each other.
Supporting lease accounting. Turn lease terms into structured data rather than text in a stored document.
What You Are Actually Buying Is Time
Building this internally means gathering definitions from leasing, property management, accounting and asset management — teams often spread across properties rather than sitting in one office.
- The first draft is the expensive part. Reviewing a proposed set of entities is a different task from inventing one, and a much shorter one.
- Disagreement becomes visible immediately. A written definition of unit surfaces the leasing-versus-accounting difference in the first session.
- It outlives the project that prompted it. The same model serves a system consolidation, a lender reporting pack, and a lease accounting effort.
Definitional sessions across leasing, property management, accounting and asset management.

Terms You Should Know Before Purchasing
Read the description above in full before you buy. Delivery is immediate and the files are yours to keep, which is also why we cannot take returns, issue refunds, or swap a purchase for a different product once it has been downloaded. What you receive is what is listed — no warranty beyond that, and no bundled customization, implementation help, or support. A Enterprise License covers everyone inside one organization; if you intend to reuse the material across several clients, the Consultancy License is the one you need. The full digital product terms govern the sale.

The questions worth settling first. Still unsure? Email us before purchasing — all sales are final.
What exactly do I receive?
The files listed under "What's Included" on the product page, and nothing beyond them. Most products are editable PowerPoint, Excel, and Word documents; some are supplied as archives containing those files. Delivery is immediate — a download link is issued as soon as payment completes.
Are the files editable, or locked?
Editable. They are working documents in their native formats, not locked PDFs or images, because the point of the product is that you customize it. A few reference guides are supplied as PDF where editing them would serve no purpose.
How long is my download link valid?
Links stay active for 7 days after purchase and allow up to 3 downloads. Save the files somewhere durable when you receive them. If a link expires or you run out of downloads, email support@finantrix.com and we will issue a new one — that is a support request, not a repurchase.
What is the difference between the Enterprise and Consultancy licenses?
An Enterprise License covers use anywhere within a single organization — your colleagues can all work from the material. A Consultancy License covers use across multiple client engagements, which the Enterprise License does not permit. If you advise more than one organization, the Consultancy License is the one you need. Full terms are at /legal/digital-products-terms.
Do I get a receipt and proof of license?
Yes, both, automatically. Your order confirmation email links to a purchase receipt and a license certificate, and normally carries them as PDF attachments as well. Unlike the download link, those documents do not expire and opening them does not use up one of your 3 downloads — they are there for expense claims, accounting, and procurement reviews that arrive long after the files do. Finantrix collects no sales tax or VAT, so the receipt shows the tax line as not applicable rather than as a computed amount.
Can I get a refund?
No. These are digital products delivered immediately and in full, so all sales are final — no returns, refunds, or exchanges once a purchase completes. That is why every product page carries a detailed manifest and an honest note on fit: we would rather you decide correctly before buying than be disappointed afterwards. If you are unsure whether a product suits your situation, email support@finantrix.com before purchasing and we will tell you.
How much customization should I expect to do?
A meaningful amount, and that is by design. These are generic, sector-level artifacts intended as a substantial head start rather than a finished deliverable for your organization. Each product page includes an honest note on fit setting out, deliverable by deliverable, what is complete and what you will need to supply.
Is implementation help or support included?
No. The purchase covers the files only — it does not include customization, implementation assistance, training, or consulting. Our consulting team is available separately on a paid basis if you want deeper help; contact us to discuss scope.
Do you offer a preview or sample before purchase?
Not as a downloadable sample. The product page is the preview: it lists every file, states the capability counts and levels of decomposition, and sets out where the artifact stops. If something specific would settle your decision, email support@finantrix.com and ask.
Can I share the files with colleagues or clients?
Colleagues within your organization, yes, under the Enterprise License. Clients, no — that requires a Consultancy License. Redistribution, resale, or publishing the material publicly is not permitted under either license.
How current is the content?
The artifacts describe business structure — capabilities, value streams, information entities — which changes far more slowly than technology or regulation. Where a product includes market-facing material such as vendor profiles, the product page says so and advises verifying currency before relying on it for a decision.
