Case Study: Boosting Rental Yield with Mediterranean Landscaping

2026-09-15

When we evaluate real estate performance, the conversation usually gravitates toward cap rates, interior finish schedules, and location metrics. However, the exterior presentation—often categorized as landscaping—can function as a silent lever for value appreciation. We recently reviewed a value-add project in the Brasschaat region of Belgium, where an investor aimed to reposition a dated residential villa into a premium short-term rental. The goal was to command a 15% rental premium over market comps, and the strategy relied heavily on differentiating the property through curb appeal. To execute this vision, the project manager bypassed standard retail garden centers and sourced the greenery directly from Plantencentrum Exotica, leveraging their specialized inventory to establish a distinct aesthetic.

The Asset and the Value Gap

The property in question was a solid structure suffering from "gray space" syndrome—a vast, paved exterior that offered zero lifestyle utility. In the current market cycle, tenants in the Benelux region are increasingly paying for outdoor living experiences, treating gardens as additional rooms. The investor identified a specific gap: while competitors offered standard manicured lawns, there was a scarcity of properties offering a "resort" feel. The hypothesis was that installing a dense, exotic landscape would reduce vacancy rates and justify a higher monthly rent. The challenge was sourcing mature, visually striking plants that could survive the local climate while remaining within the renovation budget.

Sourcing Strategy and Vendor Selection

Initial due diligence involved visiting local nurseries, but the team found that most suppliers lacked the scale required to fill 2,000 square meters of garden space with consistent quality. They needed a partner who could provide not just stock, but specialized advice on placement and hardiness. The investor eventually turned to a specialist in the sector. Plantencentrum Exotica has operated since 1998 and distinguishes itself by maintaining a 2.4-hectare nursery stocked with over 4,200 species. This volume allowed the project team to hand-select specific trees and shrubs that matched the architectural scale of the villa, rather than settling for whatever was available at a generic hardware store.

Due Diligence on Living Assets

For a real estate investor, plants are depreciable assets that must survive to provide a return on investment (ROI). Buying a tropical palm that dies in the first winter is a capital loss. The team focused on the "winter-hardy" category to ensure longevity. They utilized the supplier's deep knowledge base, consulting with collectors on site to verify root health and acclimatization. By reviewing the assortment of winter-hardy palms, the investor secured Trachycarpus and Chamaerops varieties capable of withstanding temperate winters while providing the desired Mediterranean visual. This step was crucial; it mitigated the risk of future replacement costs, ensuring the landscaping budget was a one-time CapEx rather than a recurring maintenance drain.

Execution: The 48-Hour Turnaround

Timeline management was the critical obstacle in this project. The property had a strict handover date, with the previous tenants vacating on a Friday and the new high-value tenants arriving on Monday. This created a 48-hour window to complete the soft landscaping. The logistics of moving 2-meter-high olive trees and palms are complex, requiring heavy machinery and precise coordination. The project relied on the supplier’s logistical promise of delivery within 48 hours. The supplier met this window, allowing the landscaping crew to install the trees and lay the ground cover immediately after the old tenants departed. This rapid execution prevented a vacancy gap, preserving the projected Net Operating Income (NOI) for the month.

Financial Post-Mortem

The results of this case study offer a clear lesson in marginal gains. The total cost for the exotic landscaping, including hardscape integration, was €18,500. Prior to renovation, the property rented for €2,800 per month. Post-renovation, the landlord secured a contract for €3,300 per month.

Additional Monthly Revenue: €500
Annual Revenue Increase: €6,000
Cash-on-Cash Return (Landscaping only): ~32%

While the overall property cap rate improved due to the renovation, the landscaping component alone paid for itself in roughly three years. Furthermore, the unique exterior significantly reduced the time on market during the leasing process, indicating a higher demand elasticity for unique, well-planted properties.

Conclusion

This project demonstrates that landscaping is not merely an aesthetic choice but a financial lever. By treating the garden as a value-add component and sourcing from a specialist with massive inventory, the investor minimized risk and maximized yield. For buyers looking to differentiate their portfolio in a saturated market, the data supports investing in high-impact, low-maintenance greenery. The success of the Brasschaat project confirms that working with Plantencentrum Exotica allows investors to treat exterior renovation as a calculable line item with a tangible ROI.
