## Pricing

from $1.13 / 1,000 results

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Home Value Estimate: 3 Estimates per Address, Monthly Change

**Home Value Estimate** - Paste your home addresses and get today's value from three estimate providers, plus how much it moved since your last run.

### What does Home Value Estimate do?

Every address comes back with three independent value estimates (Quantarium, Cotality, Collateral Analytics) side by side, the 12-month change, and the change since the last scheduled run - the leading value-history tool gives one Zillow series only.

- Plain street addresses in, no property ids or API keys needed
- Three value estimates per home with low/high range and date
- 12-month change and a 12-month forecast
- Change since the last run for scheduled monthly syncs
- Beds, baths, sqft, year built, property tax and assessed value

### Who uses Home Value Estimate, and for what

- Personal finance app users - auto-update the home value in their net worth every month
- Landlords - track the value of every rental in one sheet
- Agents - send owners a monthly value update
- Investors - spot homes whose value moved most this year

### Why this Home Value Estimate?

Low tools ask for internal property ids or the user's own paid API key, so a normal person cannot even start a run. This Home Value Estimate checks every run and tells you plainly when a page could not be read, instead of returning empty or wrong rows.

### Data you get from Home Value Estimate

Every result is one flat row with these fields (values from a real run):

One flat row per result.

### How much does Home Value Estimate cost?

You pay only per result (pay per event) - no monthly fee, no minimum, and the price per result is lower on Apify's Bronze, Silver and Gold plans. The exact price is on the **Pricing** tab. Apify's free plan credit is enough to try it on real input.

| You want | What you pay for |
|---|---|
| A quick test with the example | a few results |
| A daily scheduled run | only the rows that run returns |
| A big one-off export | the results delivered - set a maximum in the input |

### FAQ

**Does Home Value Estimate need a login, cookies or an API key?** No. It reads public pages only.

**Can I run Home Value Estimate on a schedule?** Yes - with Apify Schedules; each run returns fresh rows.

**Can I call it from Python, JavaScript or an AI agent?** Yes - through the Apify API, the Apify client libraries or the Apify MCP server.

**Is it legal?** It collects only data anyone can see without logging in. You are responsible for using it within the source site's terms and data protection law (GDPR, CCPA).

**What if the site blocks a request?** The run retries from a fresh connection and, if it still cannot read the page, stops with a clear message - never with made-up rows.

**Do I need proxies?** No setup needed - Home Value Estimate uses Apify Proxy by default where the site needs it.

### Troubleshooting

- **No results:** check the input (a public URL or a search term that returns results in a normal browser), then try the example input once.
- **Fewer results than expected:** raise the maximum in the input; some sites show only a part of their data without logging in, and Home Value Estimate never logs in.
- **The run stopped with a message:** the message says what the site answered; run it again later or with fewer items.
