225% Higher Revenue Through Lease Review & a Second Mobile Operator

Challenge: Low Rental Income Due to Unfavourable Contract Terms

A. Meier, a property manager based in Hamburg, had already leased roof space for a mobile antenna. However, the rental income fell short of expectations, as the existing contract was heavily skewed in favour of the network operator. Without expert advice, Mr Meier risked giving away financial advantages and entering into long-term obligations without leveraging his negotiating position.

Solution: Better Lease Terms and a Second Operator on the Rooftop

FALKENFUNK reviewed the existing lease, assessed the site value and negotiated with precision. Our experts developed a strategy that not only increased rental income from the rooftop mobile site, but also made it possible to bring in a second network operator. Thanks to our professional guidance, the following results were achieved:


+34% higher income from the existing legacy contract

Improved contract terms to ensure long-term flexibility

Additional operator – double the income from rooftop leasing

Legal protection to minimise risks for the property owner

Complete project management for an optimal outcome


“Thanks to FALKENFUNK, we not only improved our existing contract but also brought in a second tenant. Now our property is fully utilised and generating stable income.” – A. Meier

Result: 225% More Income Through a Smart Leasing Strategy

Significantly Better Terms Through Mobile Mast Lease Optimisation on Rooftops

Challenge: Lease Terms Did Not Reflect Actual Usage

An institutional property owner in Düsseldorf leased out the rooftop of their building to two mobile network operators. A routine review revealed unexpected technical discrepancies:

  • The actual rooftop usage exceeded the contractually agreed area by a significant margin

  • The technical installation was far more extensive than specified in the lease agreement

These differences were previously unknown to the owner and resulted in lost rental income.

FALKENFUNK Consulting reviewed the lease agreements, identified the imbalance, and negotiated a fair solution with the mobile operators:

✅ 65% increase in rental income, effective immediately
✅ Optimisation of the existing lease agreement, despite ongoing term
