What you need
Requirements

- For meaningful comparisons, at least two points in time or one event.
Practical guidance
Helpful tips
- Record major work promptly and link invoices to the renovation project.
- Keep the purchase price and market value as different sizes.
Deliberate limits
What this tool does not do
- An investment does not automatically increase the market value by the same amount.
- The logbook does not calculate any tax-binding values.
- It explains connections, but does not prove the cause of market movements.
Quick answers
Frequently asked questions
Is the purchase price automatically the new market value?+
It is an important market observation point, but may be higher or lower than a general estimate due to special circumstances.
Can I delete or change my own events?+
Your own entries can be corrected. Data that is automatically transferred remains assigned to its source.
