Finding value-add office properties: My 70/30 sourcing engine

The deals that give you outsized returns are not the ones every major agency house is shopping to 40 counterparties at the same time. By the time a value-add office building lands in a broadly marketed process, the spread between going-in yield and stabilized exit has already been compressed by competitive bidding. What I have learned over the past decade is that the best entry points come from the other 70 percent of the market—the buildings that never get teased to the institutional crowd.

This post is about where I actually find the opportunities I underwrite, how I read the market signals that separate real value from priced-in upside, and the screening criteria I use before I spend capital on legal and technical diligence. It is not a generic sourcing checklist. It is the sourcing engine I actually run at VVS Group.

The 70/30 split: why I chase off-market deals

My sourcing portfolio breaks down roughly 70 percent off-market, 30 percent selectively marketed. The difference matters because it changes what you can underwrite. On a marketed deal, everyone is seeing the same information—the same teaser, the same technical reports, the same broker assumptions about future tenancy. You are competing on price alone, and you are likely competing against someone with deeper pockets or lower cost of capital.

Off-market deals give me time to think. I can run my own phase-two condition survey instead of relying on a seller's engineer. I can talk to the existing tenants about their real lease intention—not what the asset manager thinks they will do, but what they have said to me in a quiet conversation. I can underwrite a capital program that is actually defensible, not padded for psychological comfort. And when I find something worth buying, I can have a price conversation with an owner who is motivated by something other than seeing if the market will give him another 50 basis points.

The 70 percent off-market also means I can walk away from garbage. If a deal does not work, there is no sunk cost in the competitive process. No advisor who has already spent fifty hours on it. No obligation to the broker who brought it in. Just a quiet file closed and a lesson learned.

Three sources of off-market flow

The off-market deals come from a small set of repeat sources. I spend more time managing those relationships than I do on any single transaction.

Special servicers and debt funds. When a commercial real estate loan goes bad in the Netherlands or elsewhere in Europe, it does not instantly go to auction. It goes to a special servicer who is working with the borrower—or working them out—toward a resolution. That resolution often means finding a quiet buyer who understands the asset, can take a long-term view, and will not blow up the wider portfolio. I have relationships with six or seven servicers across the Netherlands, Belgium, and Germany who know that when they have a repositionable office building and an underwater borrower, I will move fast and I will close. Those relationships are worth far more than any single transaction.

Tired first-generation owners. The Dutch institutional office market has a cohort of family-office and individual buyers who acquired their buildings in the 2005-2012 cycle. They bought low, held long, and have done well. But they are now tired. Asset management is a pain. The building needs a capital program they do not want to finance. A major tenant is approaching a break option. The owner has aged into a different return expectation. They do not want a public sale because it exposes them to a circus of competitive bidding and makes them look like they are dumping the asset. They want a quiet phone call from someone credible who can close inside twelve weeks.

Rotterdam, Amsterdam Zuidoost, Utrecht Papendorp—these regional hubs are full of mid-market assets held by owner-occupiers and small family offices who fit that profile. The sourcing on those deals is relentless. But once you are in the Rolodex, deal flow is steady.

Corporate occupiers consolidating. Every large corporate in Europe is right-sizing its real estate footprint. Five years of hybrid work have consolidated demand. A tech company that occupied three buildings in Amsterdam now occupies one-and-a-half. A law firm that leased four floors in Rotterdam now leases two. That means surplus space, in buildings owned by the company, that needs to move without embarrassment. Those owners do not call brokers. They call investors they know who can take the complexity off their table.

Eindhoven, with its concentration of tech headquarters, is a case study in this dynamic. I have sourced three buildings there in the past three years from owner-occupiers consolidating their footprint.

Reading the marketed teaser for real value

I do look at marketed deals, but only when something in the teaser signals that I can underwrite value that others may have missed. The trick is reading what the seller is trying to hide inside the tidy narrative.

Short weighted average lease term. When a broker is pitching a building with a 4.5-year WALT and calling it "stable income," what he means is there are major re-leasing events in years two and three. That is exactly when a value-add operator is supposed to show up. Everyone else sees execution risk. I see the window when I can upgrade the tenant mix.

Single large anchor with a break. A building that is 60 percent occupied by one tenant, with a 24-month break option coming up, looks terrifying to a core buyer. To me it looks like I have two years to execute a pre-leasing plan and hit the market with a better tenant profile. The risk is real, but it is a risk I have priced and can manage.

Larger capital backlog than the seller admits. Every office building in continental Europe has a growing CapEx backlog—aging HVAC, non-compliant EPC label, common areas that have not been refreshed in a decade. Sellers have a way of understating this, particularly if it is an unfunded liability on their balance sheet. I read the technical reports like I am looking for what is not being said. An engineer who notes "system end-of-life in estimated 24-36 months" is telling me the capital spend is actually coming in year one or two, not year four.

When a marketed deal has one or more of those flaws, I will do the work. The flaws are where the basis gets wider and the competition gets thinner.

Screening criteria before I spend money on diligence

Once I have identified a building I want to look at, I use a quick screening filter before I commit to legal and technical diligence. If these do not pass, the deal goes in the "no thanks" file.

EPC label and compliance timeline. Every office building in the Netherlands will be EPC-C or better by 2027, EPC-B or better by 2030. A building that is currently D or E label is already burning capital against the clock. I need to underwrite that the capital program gets me to B or better by exit, and that the green premium on the stabilized cap rate offsets the cost. If the label is so bad that the building is headed for non-compliance within my holding period and I cannot finance the fix into the underwriting, I walk.

Weighted average lease term. Below 3.5 years and the lease-up risk is real. Below 2.5 years and I need a lease pipeline that I have actually touched, not a broker's sketch. I will take short WALT if the pre-leasing momentum is there. But I will not take it on faith.

Tenant concentration and quality. One tenant above 40 percent is a flag. Two tenants above 60 percent combined is a red line unless the breaks are more than four years away and I have had an actual conversation with each one about their intention to renew. Tenants on individual ICAs, not master leases, without corporate guarantees—those are buildings I can upgrade. Tenants that are spinning out of a chapter-11 or a selective default—those are buildings I skip.

Capital backlog sizing and credibility. I want to know the full unfunded CapEx, not the seller's version of it. Common areas, envelope, installations, EPC improvements, fire safety upgrades—it all adds up. I commission an independent phase-two site survey on anything I am serious about, and I use that to stress-test the seller's estimate. If the seller has been understating the capital need by more than 20 percent, the relationship becomes harder.

Submarket targeting and regional thesis

I do not play core markets where institutional capital sets the spreads. Amsterdam CBD, Rotterdam CBD, the German CBD markets—those are where size and scale win and where you are competing against open-ended funds and US-based platforms. My target is the secondary and tertiary hubs where a specialist operator can actually move the needle.

Amsterdam Zuidoost is a case in point. Five years ago it was seen as peripheral. Today it has the highest population density in the Netherlands, rising employment in tech and creative industries, and office rents that are up 25 percent while CBD rents have stalled. Buildings in Zuidoost that were soft 10 years ago can now deliver 5.5 percent core cap rates and 8 percent value-add yields-on-cost. I have three buildings in execution there right now.

Rotterdam Alexander is another. It is the emerging mixed-use hub south of the CBD, with younger tenants, lower rents than CBD, better access to the highway, and genuinely strong fundamentals on employment. I sourced two repositionings there in 2024 and expect more.

Utrecht Papendorp is the tech park on the southern edge of Utrecht. It is transitioning from a pure business park to a mixed-use employment zone with residential, hospitality, and creative tenants. That transition is where value-add lives. The rents are lower than CBD, the space is more fungible, and the tenant demand from growth companies is real.

Eindhoven Strijp is a converted industrial zone with high-ceiling warehouse space that tenants are taking at better yields than traditional office. That flexibility attracts young companies and gives me multiple re-leasing pathways I do not get in a rigid six-meter-floor-to-floor office building.

These are not the markets everyone is chasing. That is the whole point. When I source in secondary and tertiary markets, the competition is thinner, the seller expectations are more realistic, and the spreads reward the work I do.

Building and maintaining the sourcing relationship

The highest-leverage thing I do is stay in regular contact with special servicers, tired owners, and corporate real estate teams, even when I am not actively seeking. A conversation every quarter. An email when I close something in their market. A direct call when something in their portfolio is moving.

Most investors wait until they need a deal to start networking. By then, they are a stranger asking for favors. The people I source from best know that I close when I say I will close, I do not flood them with ridiculous offers, and I do not blow up deals over small issues during legal. That reputation is worth more than any platform or database.

If you are serious about value-add sourcing, spend 80 percent of your time building relationships with those three groups—servicers, tired owners, corporate occupiers—and 20 percent on everything else. The marketed deals will always be there. The quiet off-market flow only comes to people the market knows and trusts.

The specifics of how I underwrite these deals once I have sourced them, and the targets I hold them to, is covered in my post on value-add real estate strategy.
