Search

The query string. Represents the property name, address, etc. We'll also surface aliases and other names, as well as other known addresses.

The expected city. When specified, matched properties will be filtered by city. Careful: the name of the city must be spelled correctly, for this reason, we recommend using the state or zip code instead.

The expected state. When specified, matched properties will be filtered by state. For example, 'CA' for California.

The zip code. When specified, matched properties will be filtered by zip code. Accept both 5 and ZIP+4 digits formats (e.g. 12345 or 12345-6789). If a leading zero is missing, it will be added automatically.

Whether to allow properties with no units to be included in the results. False by default.

The minimum year built of the rent comps. Does not filter properties with no year built.

The maximum year built of the rent comps. Does not filter properties with no year built.

Whether to allow properties with no year built to be included in the results. False by default.

Post Property

Get the unit pricing for a property given its details. We use all property and unit details (characteristics, amenities, location, etc.)
to find similar units in the market that have been rented recently. We then use the rent prices of these units to estimate the unit pricing.

Pricing

Get the expense benchmarks for a property given its details.
Our models use all property details (characteristics, #stories, amenities, location, etc.) to compute the estimates.

The CompetitionProfile object is used to explain the competition profile of a property.
It describes how many properties are in the high, medium, and low similarity buckets within a given radius (non overlapping, non-cumulative).

CompetitionProfile

The number of properties in the high similarity bucket. (similarity in [0.8, 1])

The number of properties in the medium similarity bucket. (similarity in [0.6, 0.8[)

The number of properties in the low similarity bucket. (similarity in [0, 0.6[)

CompsResponse

Defines optional settings for computing comps. These settings control the scope and criteria of
the comparison. We advise to leave these settings empty to get the most accurate results, but
they can be used to enforce specific criteria for the comparison.

CompsSettings

The maximum search radius (in miles) for comparable properties. This limits how far out
from the subject property the search for comparables will go.

Force the search to only consider units having a specific status (active, closed, or all).
By default, all units are considered.

The start date for the period within which comparable units should be considered.
This filters the data to include only those units occurring after this date.

The end date for the period within which comparable units should be considered.
This filters the data to include only units occurring before this date.

Determines whether to include outlier data in the comparison. Outliers can significantly
affect the average and median values of the comps.

regardless of other criteria.

A list of unit IDs to be excluded from the comps analysis. This can help remove
known anomalies or non-comparable units from the dataset.

Indicates whether the subject property itself should be excluded from the comps analysis.
This is useful when the subject property's data might skew the comparison.
