* 0 = all possible matches
* 1 = comparable
* 2 = comparable + better and lesser
* 3 = maximum filter

#### Comparable surface area and build year

For inner surface area the comparable function works as follows:

* 0 = all possible matches
* 1 = comparable between <10% and >10% surface area difference
* 2 = comparable between <20% and >20% surface area difference
* 3 = comparable between <30% and >30% surface area difference

For buildyear:

* 0 = all build years
* 1 = comparable between <10 and >10 buildyear difference
* 2 = comparable between <20 and >20 buildyear difference
* 3 = comparable between <30 and >30 buildyear difference

**Comparable distance**

For distance to target object

* **0**: search within the entirety of The Netherlands
* **1**: search within a maximum radius of 1 kilometers
* **2**: search within a maximum radius of 5 kilometers

**Date limit**&#x20;

To give preference to more recent properties it is possible to add the actual entry "date\_limit" to search the database for reference objects from 6 to 60 months.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.altum.ai/english/property-valuation-and-market/interactive-reference-api/comparable-functions.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
