Who benefits from the individual renovation roadmap?

If you plan to substantially upgrade your home over the next 1–10 years, the iSFP pays off twice: once through the structured sequence, and once through the iSFP bonus on subsequent measures. Typically, the report becomes worthwhile at the latest when the first major single measure (heating, roof, facade) is on the horizon.

For apartment buildings and homeowner associations (WEG), the iSFP is almost indispensable. It gives all parties a shared, technically grounded basis for decisions. On request, we prepare the report as a resolution document for the owners' meeting — with a clear cost-benefit view and a realistic timeline.

For investors and landlords, the iSFP serves as an investment decision template: which measures lift value, which secure lettability, which combine funding and modernisation allocation optimally? We look at your property from a commercial perspective — not just an energetic one.

Before an acquisition, an iSFP-oriented pre-purchase report can be useful. It shows realistically expected retrofit costs and which funding paths remain available after purchase. The retrofit perspective then flows into the price negotiation.
