Your tenancy agreement is coming to an end. Whether you stay or move will determine years of costs.
With Stay or Move, we work through both options for you – calculating costs per workstation and net present value over ten years, rather than relying on gut feeling. It’s free, regardless of which way you decide to go.
Two approaches. Both are verified, not estimated.
We carry out the assessment in collaboration with a specialist planner. There is no cost to you.
-
STAY — Stay and improve
How much is your current premises really worth? What could be achieved by refurbishing it? And what is your landlord prepared to offer if you have a genuine alternative to hand?
-
MOVE — Move house and win
What premises are actually suitable for you? How many workstations can you accommodate there? And what will the move cost — including refurbishment, relocation and double rent?
-
OUTCOME: A proposal for a decision
Both options calculated using the same criteria, based on reliable figures rather than assumptions. Ultimately, you decide for yourselves — but on a basis that will stand up to scrutiny by any committee.
What we use to measure.
Three factors determine whether a space is cost-effective. The rent per square metre is not one of them.
-
Cost per workstation
The basic unit for every calculation. Not what a square metre costs, but what a workstation costs — based on the rent inclusive of service charges, i.e. including service charges, over the entire term.
-
Net present value over the term
Both scenarios are calculated over a period of ten years, using the same indexation and the same interest rate. This is the only way they can be compared at all.
-
Negotiating position
How much your move-out would cost your landlord. This figure changes the dynamics of every lease renewal negotiation — even if you want to stay.
How much does a workstation cost you — and where could you make savings?
Three figures are all it takes. Two sliders then show what an optimised space would mean over ten years. All rent figures are quoted as ‘warm rent’, i.e. inclusive of service charges.
How this calculation is arrived at
A simplified model calculation based on your input — not a forecast or a guarantee. The comparison is based on basic rent costs over ten years, excluding indexation, discounting, renovation, moving and furnishing costs, and rent-free periods. In the full analysis, we factor all of this in and compare the net present values of both options — including what it would cost your landlord if you moved out. Your input remains in your browser; we do not store or transmit anything.
The figure above is a model. Let’s turn it into a business case.

The more expensive square metre may actually be the better value workplace.
The rent per square metre is listed right at the top of every property listing. It’s simple, easy to compare — and regularly leads to the wrong decision. This is because an efficiently laid-out space with a higher price per square metre can work out significantly cheaper per workstation than a cheaper space where each employee takes up thirty square metres.

And the bill that almost nobody takes into account: your landlord’s.
When a large tenant moves out, the owner incurs costs that very few tenants have ever put a figure on. We’ll work it out openly — using a model case: 3,700 square metres at 39 euros per square metre per month, including service charges.
| Item | Assumption | Calculation method | Cost per m² |
|---|---|---|---|
| Vacancy period until re-letting | 12 months’ marketing | 12 × 39 € | €468 |
| Vacancy period during refurbishment | 9 months of fit-out and dismantling | 9 × €39 | €351 |
| Rent-free period for the new tenant | 12-month incentive | 12 × €39 | €468 |
| Estate agent’s fee for new tenancy | 5 months’ rent | 5 × €39 | €195 |
| Demolition and new build | Construction costs per m² | flat rate | €1,000 |
| Total | 33 months without rental income | around €2,500 |
Money your landlord won’t have to spend if you stay. Anyone who knows this figure negotiates differently.
From the initial figure to the decision paper.
| Step | What happens | How you benefit |
|---|---|---|
| 1 · Site assessment | Fifteen minutes, four key figures. We’ll give you an honest assessment of whether a full analysis is worthwhile. | An initial reliable figure — free of charge and with no obligation |
| 2 · Defining objectives | Requirements, timelines and framework conditions are defined. | A clear requirements profile, which is often simply missing in many processes |
| 3 · Evaluating both options | Existing space and alternatives are planned and compared in terms of net present value. | Two fully costed options rather than a guess |
| 4 · Decision | Decision proposal, followed by negotiation and implementation. | A proposal that stands up to scrutiny by any committee |
The final outcome
- Net present value comparison of both approaches over the full term
- Costs per workstation today and in the future, including ancillary and refurbishment costs
- Occupancy and feasibility planning by an independent specialist planner
- Negotiation strategy with your landlord
- A clear recommendation — and the figures for you to check yourself
The planning is carried out by a specialist planner whom we select from our network of partners for each property. We are not tied to any particular planner, and their quote is available for your review.
It’s free of charge for you. And here’s why you can trust us.
Our aim is to ensure there are no costs to you. In every process, we strive to reach agreements with the owners that mean you incur no costs.
-
Planning
Angermann NRW will cover the planning costs — in advance, before a decision is made.
-
Fee
Our fee is paid by the owners: the current landlord if you stay, or the new owner if you move out.
-
Independence
It’s the same in both cases. Whether you stay or move house makes no financial difference to us — which is why we can advise you to stay.
The two years leading up to the loan will determine your creditworthiness.

A single percentage point lower financial standing can quickly add up to a six-figure sum over ten years, particularly for a larger property.
The best time to do this calculation is two years before the contract ends. The second-best time is today.
When does your tenancy agreement end?
A quick chat is all it takes to work out whether it’s worth it for you.
A real-life case. Anonymised, as we do not discuss client matters.
| Background | Space per workstation | Cost per workstation (all-inclusive) | Difference over 10 years |
|---|---|---|---|
| 3,700 m², city centre location, 120 workstations, lease renewal pending | 30.8 m² → 21.3 m² | €1,079 → €797 | around €4.8 million |
On paper, the existing property was the cheaper option — the alternative cost more per square metre. The full calculation showed the opposite.
All rent figures are inclusive of service charges. Assumptions: annual indexation of 2.35 per cent, discount rate of 5 per cent. Case study from the Angermann Real Estate Group.
Questions we are asked.
-
What exactly is Stay or Move?
Stay or Move is a decision-making analysis for companies whose office lease is due to expire in the foreseeable future. We carry out a full cost-benefit analysis of both options: one scenario involves remaining in the existing premises, possibly with refurbishment and a renegotiated lease, and the other involves moving to an alternative location. Both options are assessed using the same criteria — based on the cost per workstation and as net present value over the full term of the lease.
The result is a decision-making document that you can use to present your case to the management board, advisory board or shareholders. Not a recommendation that you simply have to take on faith, but a calculation that you can verify for yourself.
-
How much will it cost me?
The site assessment is free of charge. For the full analysis, our aim is to ensure that there are no costs to you: we cover the specialist planner’s planning costs up front, and we recover our fee from the property owner — the current landlord if you stay, or the new owner if you move out.
We deliberately say ‘commitment’ rather than ‘guarantee’. In the vast majority of cases, this arrangement can be implemented; should anything different apply in an individual case, we will discuss this with you before any costs are incurred — not afterwards.
-
What's the catch?
There is one, and we’d rather set it out in writing: If you have the analysis carried out in full and then, without any intervention on our part, decide to maintain the status quo — that is, neither to renegotiate, nor to refurbish, nor to relocate, but simply to exercise an extension option, for example — you will bear the actual planning costs incurred by the specialist planner.
In return, you will receive all the planning results: the occupancy concept, space requirements and feasibility study. This is work that retains its value even if you do not relocate. As soon as you renegotiate, refurbish or relocate, the following applies once again: at no cost to you.
-
They’re paid by the landlord. Why should I trust your recommendation to stay?
Because our fee is the same in both cases. Whether you stay in your current premises or move makes no financial difference to us. We earn from your decision, not from the direction you take — and that’s not just a marketing slogan, but the basis on which we operate.
The more honest way to deal with this question is to ask it openly, rather than sidestepping it. Anyone who can’t explain their business model without getting flustered probably has one that doesn’t stand up to scrutiny.
-
Isn’t that a conflict of interest?
Every piece of advice in the property market operates within a complex balance of interests. We deal with this openly, rather than hiding it. In practical terms, this means that we clearly identify any property for which you would be liable to pay commission and factor it fairly into our comparisons — like for like. You can see at any time who is paying whom for which service.
-
How do you differ from the major international firms?
There, everything is usually provided from a single source: letting, consultancy, planning, and often investment interests in the same property. This can be efficient. The question that is rarely asked, however, is: where exactly within this structure is the user’s best interest actually being considered?
We are not tied to any specific specialist planner and select the most suitable one for each property. Our fee is independent of the direction your decision takes. And we are based in Cologne; we know the properties, the owners and the key players from first-hand experience — not from a database.
-
At what size does it start to be worth it?
As a rule of thumb, this applies to office space of around 1,000 square metres or more. However, it is not the floor area alone that is decisive, but the combination of size, rent level and remaining lease term. For 1,000 square metres at a very low rent, it’s not worth the effort for either party; for 1,500 square metres in a good city-centre location, the sums involved can quickly become substantial.
We’ll give you an honest assessment of whether it’s actually worth it for you in our free location check. If not, we’ll tell you that too — and you’ll still have one more figure to go on than you did before.
-
My contract still has years to run. Is it too early?
On the contrary, this is the right time. You build up bargaining power around twenty-four months before the contract expires, not three months beforehand. If you start too late, you can no longer seriously consider any alternatives, let alone plan for and secure them — and so you end up negotiating without any leverage.
The best time to do this is two years before the end. The second-best is today.
-
We’ve actually already decided to stay.
In that case, this analysis will be particularly valuable to you. A verified move-out option is your strongest bargaining chip in any lease renewal negotiation — especially if you want to stay. Your landlord calculates very precisely what your move-out would cost him; in our example, this amounted to around 2,500 euros per square metre.
So you pay nothing to be in a stronger position in these negotiations. And if the calculation ultimately suggests you should stay — then that’s a result, not a failure.
-
We are already in talks with another estate agent.
That’s standard practice and not a problem. The question is a different one: has anyone there worked out your costs per workstation and broken down your landlord’s statement of account for you? If so, you’re in good hands. If not, you’re missing the two figures on which the decision actually hinges.
The location assessment doesn’t commit you to anything and costs you nothing. It’s simply a second opinion – nothing more.
-
Do I have to sign a contract?
Not for the free site assessment. For the full analysis, yes — and that’s fair: we cover the costs up front and bear the planning costs; in return, we get exclusive rights to the project.
The contract has been deliberately kept brief. It sets out who does what, who pays for what, and what happens if the process is terminated. No five pages of small print for a first step.
-
How long does the whole process take?
The site assessment takes around fifteen minutes for the consultation, plus an initial evaluation. The full analysis — needs assessment, market analysis, planning and net present value comparison — takes several weeks, depending on the size and complexity of the project.
We set a binding timetable at the outset, working backwards from the end of your contract. This means you can see right from the start when each decision is due.
-
What do I need to contribute?
For the site assessment, we need four pieces of information: approximate floor area, current rent, number of staff at the site and the end date of the lease. That’s all.
For a full analysis, we need to review the existing tenancy agreement and the current space situation. We do not carry out any stock-taking, interview anyone or disrupt your business operations.
-
Who draws up the plans?
A specialist planner from our network of partners — selected based on who is best suited to your building and your project. We are not tied to any particular provider and will present their quote to you without any filters.
This freedom is an advantage, not a mere detail: a planner who specialises in optimising existing properties works differently from one who develops new-build sites. The right person should work on your project, not someone with a vested interest.
-
Will my current landlord find out that I’m thinking about moving out?
Only if and when you want it. Whether, when and how an alternative is put forward to the landlord is part of the strategy we will draw up together with you. None of this will happen without your knowledge.
In many cases, it is tactically wise to signal early on that you are looking into your options. In others, it is better to exercise restraint. It is precisely this kind of judgement that forms part of our work.
-
What happens to our data?
We treat everything you entrust to us as strictly confidential and do not pass it on to third parties. Your budget, your timeline and your internal considerations remain with us.
The specialist planner receives only the information they need for their work. And the data entered into the calculator on this page never leaves your browser.
-
Do you do that outside Cologne as well?
We provide consultancy services throughout North Rhine-Westphalia, with a focus on the Cologne and Düsseldorf markets. As part of the Angermann Real Estate Group, we also have a nationwide network — which is often the deciding factor for companies with multiple locations.
-
We don’t want to move, we want to expand. Would that be alright?
Yes. The question ‘Where can I find extra space?’ boils down to the same calculation, just with a different perspective: expanding within the existing premises, adding space within the same building, or moving to a larger unit. Here, too, it is not the price per square metre that matters, but rather the cost of the additional workstation.
-
What if the analysis shows that we should stay?
In that case, we’ll let you know — and support you through the renewal negotiations. Financially, nothing changes for us, as our fee is the same in both cases. For you, however, a lot changes: you’ll go into the meeting with two fully calculated options and your landlord’s final bill – whereas most companies go in empty-handed.
-
And what if, in the end, we do nothing at all?
That, too, is a legitimate outcome. In that case, the scenario described above applies: you bear the actual planning costs incurred, and you receive all the deliverables. We consider this to be the fairest of all arrangements — it protects both parties from getting drawn into a process that neither side seriously intends to see through to the end.
Your free location assessment. 15 minutes, no obligation.
We’ll take a look at your key figures and give you an honest assessment of whether the full analysis is worth it for you. If not, we’ll tell you that too — and you’ll still have one more figure than you had before.
Whether to stay or move is your decision. Our job is to make sure it’s the right one.
