Pre-Purchase Advisory — before you sign
You are close to buying a property in Munich, the Five Lakes region or Upper Bavaria — and wondering what refurbishment costs and obligations under the GEG (German Building Energy Act) are really coming your way? We assess the property from an energy perspective before you sign — at short notice, in a structured way and with a clear report.
Independent, bankable, with a negotiation memo. Marc Strassner is listed on the dena expert register for federal funding — and is himself a property investor. He knows the buyer's perspective from his own experience and understands where a precise look before signing pays off the most.
Why a pre-purchase advisory?
For most buyers, a property is the single biggest investment of their lives. The energy-related substance is the item that is least transparent in the listing — and at the same time, it can amount to a six-figure sum if it is overlooked. A pre-purchase advisory closes exactly this gap: between the seller's marketing wording and the actual technical reality of the building.
First reason: hidden refurbishment costs. A GEG-compliant heating system, thermal protection for the roof and outer walls, controlled ventilation, hazardous substances (asbestos, MMVF (Man-Made Vitreous Fibres), PAH (Polycyclic Aromatic Hydrocarbons)), an aged heating-oil tank — such items rarely show up in the listing, yet they quickly add up to figures that substantially affect the purchase price. Anyone who knows this before signing negotiates with arguments rather than gut feeling.
Second reason: GEG obligations on change of ownership. With the purchase, obligations take effect that the previous owner often avoided for decades — replacement obligation for old constant-temperature heating boilers over 30 years old, insulation obligation for the top-floor ceiling, hydraulic balancing. These obligations typically apply within a few years after change of ownership and are not negotiable.
Third reason: funding strategy is decisive for the purchase. Anyone who has the individual refurbishment roadmap (iSFP) drawn up before the purchase can strategically use the 5 percent iSFP bonus on BEG individual measures and additionally examine the FKG track within the City of Munich. If the iSFP is only drawn up after purchase, part of the optimisation opportunity is lost because certain measures have already been commissioned. We examine funding options on a case-by-case basis — and plan the right entry point with you.
The 12-point pre-purchase checklist
We work through these twelve points systematically in every pre-purchase advisory. They form the backbone of the later report and ensure that no relevant item is overlooked.
- Building envelope — Heat transmission of outer walls, roof, basement ceiling, base plate — record component thicknesses, estimate U-values, identify weak spots such as thermal bridges or uninsulated components.
- Heating system — Heat generator age, fuel, efficiency, GEG replacement-obligation risk, heating surfaces — does the system fit the building, or is a replacement due within a few years?
- Hot water & storage — Separation from heating, storage volume, circulation, legionella risk in larger systems — indicators of modernisation needs and possible follow-up costs.
- Windows & doors — Glazing type, U-value, installation situation, mould risk at connection points — often a hidden item that quickly becomes significant in larger properties.
- Ventilation & moisture protection — Existing ventilation systems, traces of mould, indoor climate, signs of building-physics issues — often critical, especially after partial refurbishments.
- Electrical installation — Main distribution, residual-current protection, cable age, prepared routes for PV, wallbox or heat pump — important for the later refurbishment sequence.
- Heating-oil tank / gas connection — Decommissioning and disposal costs for the oil boiler, availability of connections for alternatives such as heat pump, pellet or district heating — often decisive for the roadmap.
- Hazardous substances — Asbestos in roof coverings, floor coverings or facade panels, MMVF in old insulation, PAH in adhesives — indications based on year of construction and materials.
- GEG obligations — Which replacement, insulation and balancing obligations apply within the next five years after change of ownership — and which of these are relevant to costs in the short term?
- Funding potential — BEG, KfW 261, BAFA individual measures, FKG Munich, tax advantages possible — we examine funding options on a case-by-case basis and sketch what makes sense for this property.
- Refurbishment sequence — Which measures make sense in which sequence — today, in three years, in ten years? A smart sequence saves significant costs in many cases.
- Value increase potential — Energy-class jump, ESG relevance for rental or later sale, market arguments — measurable in many cases, the actual result depends on the market.
Process in 4 steps
We know that buyers are under time pressure. That is why our process is consistently designed for fast, reliable decision foundations — from the first feedback to the bankable report.
Listing review(24-48 h, online)
You send us the listing, the energy certificate (if available), floor plans and photos. Within one to two working days, we provide initial feedback: which risks we see in the documents, where the open questions are, whether a site visit is worthwhile or whether a purely online assessment is sufficient. You receive an honest assessment before commissioning the full advisory package.
Site visit(2-3 h, on site)
Measurement and component check, assessment of the heating and hot-water system, visual inspection for hazardous substances, ventilation and moisture assessment, photo documentation. Ideally, you accompany us on site — your questions are clarified directly and you see with your own eyes what is technically classified in the report later.
Report(5-7 working days)
You receive a written, bankable report: the complete 12-point assessment, an estimate of refurbishment costs in three scenarios (minimum GEG, obligation plus reasonable measures, efficiency-house standard), an outline of the funding potential and concrete negotiation pointers for the conversation with seller or estate agent.
Negotiation support(1-2 appointments, optional)
If you wish, we accompany your price negotiation with arguments from the report or clarify open technical questions with seller and estate agent. This can be a phone call, a joint site visit or a written preparation of the most important negotiation points — depending on what the situation requires.
What you actually receive
The central deliverable is a written, bankable DOCX report, typically twelve to twenty pages long. Bankable means: the report is structured and documented in such a way that it is recognised as a reliable decision foundation in financing discussions with your house bank or KfW — relevant if refurbishment funds are to be co-financed.
In the report, you will find a 12-point assessment matrix with a risk traffic light: each of the twelve points from the checklist is classified as green, amber or red, with a brief justification. At a glance, you see where the critical points of the property lie — and which topics are currently rather uncritical.
The estimate of refurbishment costs is divided into three scenarios: minimum (only what is legally required under the GEG), obligation plus sensible additions (economically reasonable standard) and efficiency-house standard (ambitious full refurbishment with maximum access to funding). This way, you see the bandwidth and can choose the strategy that fits you.
Added to this: a funding-strategy outline (which programmes make sense in which sequence — we examine funding options on a case-by-case basis), a refurbishment roadmap with a time horizon of zero to three, three to ten and ten years and more, a negotiation memo (which items are concretely suitable as arguments for a price reduction), a forecast of the likely energy class after refurbishment and complete image and photo documentation of the site visit.
What does the pre-purchase advisory cost?
The following prices are flat rates including VAT and apply to properties in southern Munich, the Five Lakes region and Upper Bavaria. We name the exact fixed price after a brief review of the listing.
| Service | Flat rate incl. VAT | Note |
|---|---|---|
| Listing review (online, 24-48 h) | approx. 250 € – 450 € | Initial assessment, no site visit |
| Full advisory single/semi-detached/terraced house (site visit + report) | approx. 950 € – 1,500 € incl. VAT | incl. negotiation memo |
| Full advisory multi-family house (up to 5 units) | approx. 1,400 € – 2,200 € | incl. economic feasibility outline |
| Full advisory multi-family house (6+ units) | from 2,000 € — individual | depending on size |
| Negotiation support (additional) | approx. 150 € – 250 € per appointment | on request |
The pre-purchase advisory itself is not directly eligible for funding. In the event of a purchase, however, it can be transferred seamlessly into a BAFA-funded energy advisory (iSFP) — the pre-purchase data then flow in, which accelerates the iSFP and in many cases reduces the effective owner contribution.
Pre-purchase advisory from a buyer's perspective
What distinguishes our pre-purchase advisory from a classic surveyor's report: Marc Strassner is himself a property investor. He knows the negotiation and purchase dynamics not only theoretically from textbooks, but from his own practice — the mix of time pressure, gut feeling, agent arguments, financing questions and the worry of having overlooked something essential. It is precisely this buyer's perspective that shapes our reports: they are not only technically correct, but tailored to the decision you actually have to make.
We are listed on the dena expert register for federal funding. This means two things: first, our report is bankable, i.e. reliable enough for financing discussions with your house bank, savings bank or KfW. Second, after the pre-purchase advisory — if you buy — we can transition without a break into the BAFA-funded energy advisory and into the iSFP, with all the funding options that depend on it.
Independent position means: we have no craftsman commission interest, no estate-agent mandate, no hidden link to the seller. Our recommendation to you is exactly that — a recommendation in your interest, free of incentives to favour a particular product or measure.
Regional experience: we assess properties in southern Munich, the Five Lakes region and Upper Bavaria. We know the building stock of the region — Wilhelminian-era, the 1950s to 1970s, the 1980s, farmhouses, lakeside villas — and know which weak points are typical. Our locations in Grünwald and Utting on Lake Ammersee mean short journeys within the region, typically twenty to forty-five minutes to the site visit.
