Abstract

Disclosed systems and methods can determine predicted rental income, estimated error of the prediction, and a set of comparable rental real estate properties for use in the valuation of a subject real estate property rental value. In one embodiment, the rent prediction system receives rental information about real-estate properties, determines feature characteristics, trains a rent amount prediction model using the feature characteristics, determines a second set of feature characteristics based on the output of the rent amount prediction model, and trains an error prediction model using the determined second set of feature characteristics. Using the trained models, the systems and method may predict a rental value and prediction error for one or more subject properties.

Claims

1. A computer-implemented process for predicting a rent amount of a subject property comprising:

(a) accessing one or more data repositories to identify rental data associated with a plurality of real estate properties, wherein the rental data comprises at least a location and a rent amount associated with each real estate property;

(b) accessing one or more data repositories to identify non-rental data associated with a plurality of real estate properties, wherein the non-rental data comprises at least one of employment data, market trends data, vacancy data, or income data associated with respective geographic regions associated with each real estate property;

(c) developing a rent amount model based at least in part on the identified rental data and non-rental data associated with the plurality of real estate properties;

(d) identifying one or more characteristics associated with the subject property;

(e) estimating a first rent amount associated with the subject property by application of the one or more identified characteristics to the generated rent amount model;

(f) developing an error model based at least in part on the identified rental data and non-rental data associated with the plurality of real estate properties;

(g) estimating an error range associated with the first rent amount by application of the one or more identified characteristics to the generated error model; and

(h) storing the estimated rent amount and error range in a data repository,

wherein steps (a)-(d) are performed by a computerized analytics system that comprises one or more computing devices,

said process performed by a computing system that comprises one or more computing devices.

2. The process of claim 1, further comprising, (i) smoothing the rental data over a plurality of nested geographic areas.

3. The process of claim 1, further comprising, (i) determining a list of one or more comparable properties within a set distance of the subject property, and (j), estimating a second rent amount associated with the subject property, wherein the second rent amount is based, at least in part, on the list of one or more comparable properties.

4. The process of claim 3, further comprising, (k) estimating a third rent amount associated with the subject property, wherein the third rent amount is based at least in part, on the first rent amount and the second rent amount.

5. The method of claim 1, wherein the rent amount model and the error model are comprised of computer instructions configured to implement a gradient boosting tree algorithm.

6. The process of claim 1, wherein the error range comprises a forecast standard deviation.

7. The process of claim 1, wherein a confidence score is determined based, at least in party, on a mapping of the error range.

8. A computerized system for predicting a rental value of a subject property, the system comprising:

data storage;

a computer system comprising one or more computers, said computer system configured to at least;

receive rental information from one or more data sources comprising rental data associated with a plurality of real estate properties, wherein the rental data comprises at least a location and a rent amount associated with each real estate property;

receive non-rental information from one or more data sources comprising non-rental data associated with one or more geographic regions comprising real estate properties, wherein the non-rental data comprises at least one of employment data, market trends data, vacancy data, or income data;

train a rent amount model based at least in part on the rental information associated with the plurality of real estate properties and the non-rental information associated with one or more geographic regions;

train an error model based at least in part on the rental information associated with the plurality of real estate properties and the non-rental information associated with one or more geographic regions;

identify one or more characteristics associated with the subject property;

calculate a first rent amount estimate associated with the subject property by application of the one or more identified characteristics to the trained rent amount model;

calculate an error range estimate associated with the first rent amount estimate by application of the one or more identified characteristics to the generated error model; and

store the first rent amount estimate and error range estimate in the data storage.

9. The system of claim 8, wherein the computer system is further configured to determine a list of one or more comparable properties within a set distance of the subject property and calculate a second rent amount estimate based at least in part on the list of one or more comparable properties.

10. The system of claim 9, wherein the computer is further configured to calculate a third rent amount estimate, wherein the third rent amount estimate is based at least in party on the first rent amount estimate and the second rent amount estimate.

11. The system of claim 8, wherein the rent amount model and the error model are comprised of computer instructions configured to implement a gradient boosting tree algorithm.

12. The system of claim 8, wherein the error range comprises a forecast standard deviation.

13. The system of claim 8, wherein a confidence score is determined based, at least in party, on a mapping of the error range.

14. A non-transitory computer storage medium which stores executable code that directs a computerized system to perform the steps of a method comprising:

accessing, by a computerized analytics system that comprises one or more computing devices, one or more data repositories to identify rental data associated with a plurality of real estate properties, wherein the rental data comprises at least a location and a rent amount associated with each real estate property;

accessing, by the computerized analytics system, one or more data repositories to identify non-rental data associated with a plurality of real estate properties, wherein the non-rental data comprises at least one of employment data, census data, loan application data, property sales data, education data, vacancy data, or income data associated with respective geographic regions associated with each real estate property;

developing, by the computerized analytics system, a rent amount model based at least in part on the identified rental data and non-rental data associated with the plurality of real estate properties;

developing an error model based at least in part on the identified rental data and non-rental data associated with the plurality of real estate properties;

identifying, by the computerized analytics system, one or more characteristics associated with the subject property;

estimating a first rent amount associated with the subject property by application of the one or more identified characteristics to the developed rent amount model;

estimating an error range associated with the first rent amount by application of the one or more identified characteristics to the developed error model; and

storing the first rent amount and error range in a data repository.

15. The non-transitory computer storage medium of claim 14, which stores executable code to perform the steps of the method, the method further comprising smoothing the rental data over a plurality of nested geographic areas.

16. The non-transitory computer storage medium of claim 14, which stores executable code to perform the steps of the method, the method further comprising calculating a second rent amount based at least in part on one or more comparable properties located within a set distance from the subject property.
