Since August, gif e.V. has listed EstateMate on its website as a success story for its guideline on data rooms and document management. We built our document management on that guideline from the start.
The reason is simple: your documents have more readers than you do. The bank wants to see them when a loan comes up for renewal, your tax advisor needs them for the annual accounts, and when you sell, the buyer’s lawyer works through them line by line. Every one of them brings their own checklist, and if your documents are classified properly, you can answer any of those checklists from the same place with a single filter.
Why there was no rule for this
There has never been a shared standard for property documents. Banks have their own document lists, buyers their own indexes, and most portfolios a filing system that grew over the years. gif has published a guideline to change that. It gives every document in a portfolio a fixed place, from the land register and the leases with their amendments through to loan agreements and service charge statements. Anyone who files by it has, for the first time, really got everything together.
So far the guideline is used mainly in large portfolios, where a team runs the data room full time. Everywhere else the filing simply grew. That goes for most private landlords and for plenty of smaller funds as well: folders set up on instinct, file names that depend on the day, and an inbox doing the job of an archive. By the third change of property manager, nobody can say which version of a lease is current. The team was never the issue. There was just no rule for where things belong and what to call them.
That is the rule we built into the software. The catalogue sets the structure and the system does the filing.
What missing structure costs
You feel it at the receiving end. The buyer’s lawyer sends over an index with a hundred line items, and someone spends two weekends sorting PDFs into it, checking whether each lease has its amendment attached and flagging what is missing. Every gap comes back later as a price reduction or a warranty in the sale contract.
A classified filing spares them that job, and it spares you too.
“The standard reaches a market segment that has hardly worked in a standardised way so far.”

What gif compliant means in practice
Every document in EstateMate carries the five details the guideline asks for:
- Document class from the gif catalogue, for example lease
- Subclass, where the catalogue has one, for example residential
- Phase: planning, construction, operation or transaction
- Partner: who is involved, such as the tenant, the bank or the property manager
- Structure point: legal entity, portfolio, property or unit
Five details no file name can hold, which is why filing by file name always breaks down in the end.

There are no folders. A document lives through its attributes and shows up wherever it belongs, whether you are looking at the company, the property, the unit or the tenant. It is filed once and visible in every view. If you want the insurance policies for all your buildings, you do not go clicking through folders. You ask for them.
You never have to learn the catalogue
The gif catalogue runs to dozens of classes and subclasses, and you will not need to memorise a single one. That is the point.
When you upload a document, an AI module suggests the class and subclass and tells you how confident it is. The other details are filled in from the class, you confirm or correct, and that is it. If the confidence is low, the document comes to you for review instead of landing in the wrong class. The completeness checklist for each property and the document search both work off the same classification.
The standard does its work in the background. You notice it because you find things.
What you get
Your bank gets what it asks for. Before a loan renewal, the bank wants to see the leases, insurance policies and land register extracts for every building. In a classified filing that is a single filter, and the package is on its way. Your figures follow the gif definitions of rental income and vacancy, so the bank has nothing to convert.
Every figure has a document behind it. A tax auditor wants to see how a tenant’s deposit developed over eight years, plus every rent adjustment with the evidence for it. Every rent and every deposit in the system is tied to the document it came from, so that is a question for the filing rather than an afternoon in the basement.
Your documents are ready to hand over. When you sell, the data room is an export. The buyer’s index comes in and the documents are already there. Retention periods, versioning and an audit trail that meets GoBD, the German rules for digital bookkeeping records, are built in. Anything filed by gif can be passed on already classified, whether to the property manager, the bank or a buyer.
Paperwork is still work. It just happens once instead of every time someone asks.
