Start with shared criteria
Two houses can look similar in listings yet suit very different plans. Before comparing prices, write your criteria: location, use, availability, acceptable work and total budget. Separate essentials from preferences. This preparation prevents changing criteria with every appealing photograph. It also helps explain why a cheaper property might require effort you do not want to undertake.
Prepare a separate file for each property
Collect each house’s documents in a separate folder with a clear reference. Check dates and sources. Do not analyse a mixture of documents from several lots: conclusions become hard to attribute. Record missing documents for each property. Your comparison should not treat an empty box as an advantage. Unknown information remains uncertain even when the other file explicitly describes a constraint.
Prepare your next step: Choosing between two properties? Compare the life that comes with them.
Compare analyses in the dashboard
In ComparImmo, create an analysis from a compatible PDF for each file, then use the dashboard comparator. It can compare two to four analyses. Examine themes individually and return to documents where a point affects your decision. The table makes differences readable. It does not guarantee that all useful documents were supplied or every technical item correctly interpreted.
Add viewings and answers received
Document comparison should be checked against reality. After visits, revisit the same questions for both houses and request missing details from the relevant contacts. Distinguish your observations, statements received and available documents. A feeling about brightness differs from a certificate; an oral work estimate is not a quotation. This discipline helps you understand the quality of each item rather than treating everything equally.
Share an understandable decision
You can view the comparison online and download its PDF. Use it to explain your reasoning to someone supporting you: what attracts you, what concerns you and what remains to check. Bidding takes place on Biddit under each sale’s conditions. ComparImmo neither chooses the property for you nor guarantees a bargain. The desired result is a decision you can explain using checked information.
