The hidden cost of a bad housing experience: how corporate housing affects employee retention

The international assignment starts before the first day of work. It starts the moment an assignee walks through the door of their new apartment. That moment, the cleanliness of the space, the working Wi-Fi, the instruction manual for the heating system, is the first data point a professional uses to judge whether the move was worth it. Most relocation agencies know this. Very few have built a housing strategy that actually accounts for it.
The numbers behind early assignment failure
International assignments are expensive. According to Mercer, the average cost of a failed assignment — recruitment, relocation, and productivity loss combined — runs between €300,000 and €1 million per employee. The most cited reason for premature return? Personal and family adjustment difficulties. That category quietly absorbs a significant number of cases where the housing was simply wrong: poorly equipped, slow to maintain, or misaligned with what the assignee was expecting.
The relocation agency is rarely blamed directly. But it is rarely hired again.
The first 90 days are not forgiving
The first three months are the most fragile part of any international assignment. The professional is adjusting to a new city, a new team, a new role, and often a new language. Every friction point during this period hits harder than it would later.
When that friction comes from housing — a broken boiler that takes four days to fix, internet that drops during video calls, a landlord who won't respond to messages in English — it doesn't stay in the apartment. It bleeds into the workplace. It becomes the story the assignee tells their partner every evening. It becomes the reason they start quietly looking for a way out.
Brookfield Global Relocation Services has tracked this for years: spouse and family dissatisfaction, driven largely by daily living conditions, is the single biggest cause of assignment failure. Housing is the daily living condition the relocation agency directly controls at placement.
What "all-inclusive" actually means under pressure
The all-inclusive model is usually sold on administrative convenience: one invoice, one contact, no utility setup. These are real benefits. But they miss the point. When a professional moves into a Nested apartment, the space is fully operational from day one. The Wi-Fi works. The apartment has been professionally cleaned to a documented standard. Every appliance has been tested. Maintenance requests go to an in-house team, available seven days a week, with tracked response times.
For the assignee, the result is simple: housing is never a problem they have to solve. It works. And when something breaks, the response is fast — not a three-day negotiation with a private landlord who is reluctant to spend.
That absence of friction in the first 90 days is not a luxury. It is the difference between an assignment that succeeds and one that ends early.
The relocation agency's blind spot
Most agencies measure performance at placement: Was the apartment confirmed? Did the assignee move in on time? Was the invoice correct? Right questions. But they stop at the door.
What happens after check-in is where most housing partnerships fall apart. The landlord who answered calls during the viewing stops picking up once the contract is signed. The "professionally managed" property turns out to mean a local handyman with no defined response time. The consultant ends up fielding calls from a frustrated assignee about a clogged drain at 8 PM on a Friday.
This is not an edge case. In conversations with relocation professionals across Brussels, it comes up constantly — and it almost never appears in post-placement satisfaction surveys, because those surveys run before the problems start.
The question worth asking is not "did the apartment pass the move-in inspection?" It is: what does the housing partner actually do when something breaks in month two?
Reframing housing as a retention investment
Corporate clients increasingly want more than placement. They want data. They want auditable standards. They want to know that if an assignment fails, it did not fail because of something as preventable as inadequate housing.
The agencies best placed to answer that question have moved beyond apartment sourcing into structured housing partnerships — working with providers who apply consistent standards across their portfolio, produce compliance documentation on request, and have operational systems built to respond rather than react.
In Brussels, where the rental market is fragmented and regulatory requirements are tightening, this matters more than in most European capitals. The gap between an informal private landlord and a professionally managed housing portfolio is not just about amenities. It is about reliability, accountability, and the documented performance that HR departments are starting to demand.
The metric missing from most housing contracts
Assignment retention is rarely written into a housing partnership agreement. It probably should be. At minimum, it should be part of the conversation when evaluating a housing partner. Not just: can you provide X apartments at Y price? But: what is your protocol when something fails? What are your documented response times? What does "in-house maintenance" mean in practice?
At Nested, those answers are specific. Our maintenance team is Brussels-based, available seven days a week, and works exclusively within our managed portfolio. We do not forward calls to a third-party helpline. When an assignee reports a problem, the person who responds is the same person who knows the apartment.
That setup is not the easiest way to run a housing business. It is the only way to provide the consistency that keeps assignments — and client relationships — going.
