The review
before your decision

Before an acquisition, before a sale
and for your existing assets.

We review the documents, calculate the interdependencies
and make your position evidence-based.

Discuss your plans

The IM states an income figure. The documents show what supports it. We read both, check the figures and back every discrepancy with its *source.*

01 / OUR STANDARDFROM OUR REVIEWS.

Leases, costs and building services
reviewed a second time

We combine hands-on property experience with our own review and calculation tool, so that buyers can assess risks, vendors can substantiate their position and owners can develop their portfolio further.

Typical findings from our reviews

What a second look reveals

In the IMIn the documents
Passing rent per rent rollTwo leases terminated, one already expired
Non-recoverable costs as a flat-rate allowanceService charge cap in the anchor tenant's lease, with the owner bearing the difference
Lease terms per rent rollOption not exercised, rent-free months in an addendum
Maintenance in a normal yearMaintenance backlog per maintenance report, not in the budget

Each of these points changes the income and therefore the price. We identify each one, evidence it and quantify it in euros.

Every figure with its source.

Document and page appear directly in the result. Anyone wishing to verify a figure finds the passage straight away.

Every assumption identified.

Evidence and judgements are kept separate. Assumptions can be switched off or changed.

Every effect in euros.

Each finding is translated into income and purchase price, calculated transparently and reviewed by property professionals.

02 / YOUR PLANSCHECK. REVIEW. SUPPORT.

Three occasions
for a review

Whether buying, selling or holding, we review the same documents, each time with a different question. It starts with a fixed-fee check; you then decide whether the full review is worthwhile.

01

Buying

A closer look before you buy.

From the first IM to the pricing and financing decision. You know which income is evidenced and which questions remain open.

03 / THE RESULTTHIS IS WHAT THE RESULT LOOKS LIKE.

Documented figures and assumptions
are kept apart in the report

From document to decision, the derivation stays visible. Change the assumptions and see what moves in the calculation.
