As assets evolve, so do their operational, financial and compliance requirements. Accordingly, a growing portfolio often eventually needs a rethink around how it’s managed, and who should take responsibility for doing so. Sometimes, this is prompted by a specific event, such as a new acquisition, heightened reporting expectations, or a need for clearer financial visibility. In other cases, it may just become gradually apparent over time that there’s now a need for a different approach.
This decision will directly influence how well the portfolio performs, so there are a lot of aspects that need to be carefully considered when it comes to commercial property management. Here are some of the most significant.
Key considerations
| Criterion | In house | External |
| Control | In-house provides direct control, with the in-house team retaining oversight of day-to-day decisions and priorities | External requires clear governance and a trusted partner relationship, and discussions over processes that ensure alignment with the key objectives |
| Expertise | In-house depends on the calibre of the staff, with internal knowledge that’s shaped by the team’s individual experience and capacity | External provides established sector knowledge and multi-client learning, with insight drawn from a wider range of assets and scenarios |
| Technology access | In-house requires significant investment (upfront and ongoing) in property management and financial reporting platforms and systems | External partners provide tried-and-tested systems as standard, with established platforms designed for consistent reporting and operational visibility |
| Cost | In-house has fixed overhead costs – including salaries, systems and operational expenses – that will remain constant as the portfolio evolves | External can scale with portfolio size, and typically reduces cost per unit at scale |
| Geographic coverage | In-house is limited by the team’s location, with its reach defined by where they operate and travel | External specialists operate across the UK from established networks, with national coverage for consistent management across multiple regions |
| Governance quality | In-house depends on the company’s internal culture, with processes and standards influenced by how the organisation manages compliance and reporting | RICS-regulated external partners apply documented, auditable standards, with structured governance that aligns with recognised industry frameworks |
Control – the case for in-house
It’s not uncommon for commercial property management strategies to start with in-house teams, especially for smaller portfolios. It’s generally seen as more straightforward and more cost-effective. Many portfolio owners also prefer the direct oversight that in-house property management provides, so if the portfolio is closely held, or the owner wants to be involved in the day-to-day running of their portfolio, it may be worth considering. It provides full visibility of the team as they control lease negotiations, contractor selection, occupier relationships and capital expenditure (CAPEX). That makes it easier to retain a clear view of the continuous performance of all assets, and can ensure that every decision is taken in line with the key priorities and commercial strategy.
The main trade-off is that this direct control requires a considerable amount of management capacity. As the portfolio grows, the number of decisions, interactions and oversight requirements will increase across every asset. The team will therefore need the capacity to manage this volume, and still have the time and resources they need to maintain consistently high standards.
Expertise – the case for external
External commercial property management involves bringing in a specialist organisation to handle asset performance. This approach provides access to expertise that’s built across multiple portfolios, sectors and client types. An experienced external property manager will have developed multi-portfolio and multi-sector knowledge through exposure to a wide range of assets and operating environments, which gives them a level of insight that in-house teams often find difficult to replicate unless they’re particularly well-resourced.
External specialists are also constantly reinforcing their expertise using current market intelligence. They have up-to-date insight into rental values, lease terms and occupier behaviour across different sectors and regions, and continuously refresh their knowledge through active deal flow and ongoing transaction exposure. All this means the portfolio can benefit from decisions that are informed by a comprehensive knowledge of real-time market activity, and direct transactional experience.
It’s worth noting that while in-house teams can also develop their own strong expertise over time, it’s typically rooted within the narrow context of their own portfolio. In other words, most in-house asset managers don’t benefit from the type of cross-portfolio learning that’s developed across hundreds of managed units, as an external specialist does. This is one of the major reasons why so many portfolio owners graduate from internal teams to external partners when their portfolio grows to become larger, more complex, geographically spread, or become subject to formal governance and reporting requirements.
If your portfolio is reaching a point where your internal capacity is already stretched, it may be time to review whether something needs to change in your current management approach.
Scenario comparison – which model fits best?
| Scenario | Suggested Approach |
| Single multi-let building, owner actively involved in day-to-day | In-house or owner-managed can be a viable option, as the limited scale and the owner’s direct involvement means that less specialist expertise is required |
| Single asset, owner not based locally or with limited property expertise | An external partner can be a suitable approach, as they can add immediate value through local knowledge, compliance capability and established occupier management processes |
| Growing portfolio, 5–20 assets across mixed sectors | An external partner will start to become more suitable approach at this stage, as the volume of decisions and the breadth of expertise that’s required will begin to exceed what a small in-house team can sustain |
| Diverse UK-wide portfolio, institutional ownership | An external specialist is typically the stronger choice in this context, as they can provide wide geographic coverage, as well as reporting governance, integrated technology infrastructure and senior-led accountability as standard |
| Local authority or public sector with commercial property holdings | An external partner with public sector experience is typically the more suitable approach in this context, as they can provide the governance rigour, RICS-regulated reporting and accountability structures that often can’t match |
The hybrid option: strengthening an in-house team
Some portfolio owners choose a hybrid approach – retaining the strategic oversight and key relationships of an in-house approach, while outsourcing the more complex elements to an external specialist. This can include tenant acquisition, compliance, debt management and reporting – all instances where additional expertise can strengthen how these areas are handled, and without changing the overall structure of the team. It’s an approach that’s less common than fully in-house or fully external models, but one that’s sometimes used in situations where an existing team is already in place and performing well in specific areas.
Langtree works with clients on this basis too, drawing on our considerable pool of in-house expertise to supplement in-house teams without replacing them. This enables the existing property management team to remain in place, while supporting them with senior-level asset management expertise and governance in specific areas – all with a view to achieving each client’s specific commercial goals.
How else can Langtree help?
As we began by saying, the choice between using internal or external teams for commercial property management doesn’t have a universally right answer – the best solution in each case will be strongly dependent on the key characteristics of the specific portfolio at hand. If the portfolio is at an early stage, or it’s closely-held, in-house may be the most suitable initial approach. If the portfolio is more developed in terms of scale, complexity or geographic spread, an external specialist will typically be able to deliver better outcomes – including stronger expertise, more robust governance, better technology, and lower total cost at scale.
This is exactly where Langtree can help. With £24 million in rent roll and 3 million sq ft under ongoing management across both public and private sector portfolios, we can provide all the in-depth expertise, governance knowledge and reporting capability required by complex portfolios.
