The buyer's side states a large renovation sum and wants to deduct it from the price. Perhaps the amount comes from a quote, perhaps from a rough estimate. You should not respond to this with your own remote diagnosis or with an immediate price reply. Our editorial method for Austria and Germany helps to understand the actual basis of the proposal. It does not provide construction cost figures and does not assess any defect.
Clarify the purpose of the stated figure
Ask which measures are meant by the sum and what the figure is based on. A concrete service offer, a professional cost estimate and a personal modernisation wish list are different bases. Use the information actually presented; a heading “Sanierungskosten” does not yet answer the scope.
Separate the expressed price request from an asserted technical fact. The buyer's side may make a decision that suits them. Whether a particular measure would be technically necessary or legally owed, however, requires an appropriate examination.
Break down the included scope
Our recommendation: Assign each discernible block of measures to a reason. Is it about a described condition, a personal comfort wish or an investigation still to be carried out? Mark missing details. Do not invent the technical execution yourself to make the list look complete.
Also pay attention to the temporal basis. Does the assessment refer to the actually offered property and its current condition? Which parts were inspected and which limits were stated? An external quote for another house is not a cost basis confirmed by this article for this property.
An invented amount with different aims
An interested buyer wants to purchase an older house and submits an overall estimate for the bathroom, kitchen and a roof measure that still needs to be examined. The seller initially perceives the amount as an attack on the condition of the house. In an orderly conversation it becomes clear that the kitchen mainly concerns a personal redesign, while the roof issue really does need further investigation.
Both topics remain relevant in the negotiation, but are not presented as the same technical necessity. The seller has the specific outstanding roof question professionally examined and can then explain their offer position more precisely.
Use your own evidence appropriately
Existing invoices or technical reports are assigned to the affected area. An older repair does not automatically prove that every measure mentioned today is superfluous. Likewise, a current single report is not extended without examination to a complete renovation list.
New facts also belong in appropriate sales and contract advice. The article does not determine a general disclosure obligation, any warranty consequence or any statutory price reduction. It recommends consciously separating technical clarification and negotiation.
Decide on the overall deal afterwards
When the scope of the statement is understandable, you check which price expectation and conditions are acceptable to you. The amount does not have to be mathematically taken one to one as a deduction or rejected outright as a lump sum. Which economic decision is sensible depends on your specific offer and your alternatives; no general effect on value is claimed here.
The result of the discussion can be a changed price expectation, a further investigation or an unsuitable purchase idea. What matters is that the decision is not triggered solely by a large but substantively unclear figure.
