Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. 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. Actors are written with capital "A". ## 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. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Real Estate Financial Monitor — ROI, Cap Rate & Investment Analyzer Automatically analyze any property listing and get full financial metrics. Works on Zillow, Redfin, Realtor.com and more. **No API keys needed.** --- ### What This Actor Does Paste in any property URL and get back: **Property Data (auto-extracted)** - Address, price, beds, baths, sqft, year built - Days on market, HOA fees, lot size - Zestimate vs listing price gap - Tax assessment value and annual taxes - Price history (last 5-8 transactions) - School ratings, Walk Score, Transit Score **Financial Calculations (from your inputs)** - Monthly mortgage payment - Monthly ownership cost (mortgage + expenses + HOA) - Cap Rate (%) - Cash-on-Cash Return (%) - Gross Rent Multiplier - Price-to-Rent Ratio - Annual Net Operating Income (NOI) - Annual Cash Flow - Break-even rent needed - Down payment amount **Investment Summary** - Investment rating: Excellent / Good / Fair / Poor - Recommendation: Buy / Hold / Pass - Underpriced vs Zestimate signal - Cash flow positive/negative flag --- ### Use Cases - **Buy-and-hold investors** — evaluate dozens of properties in minutes - **House flippers** — check price vs tax assessment and price history - **First-time buyers** — compare total monthly cost across listings - **Real estate syndicators** — batch analyze 50+ deals quickly - **Portfolio managers** — monitor property values over time - **Agents** — build investor reports for clients automatically --- ### How To Use #### Basic: Single property ```json { "propertyUrls": [ "https://www.zillow.com/homedetails/456-Oak-Ave-Austin-TX-78701/12345_zpid/" ], "estimatedRent": 2800, "downPaymentPct": 20, "mortgageRatePct": 7.0, "mortgageYears": 30, "annualExpenses": 5000 } ```` #### Batch: Multiple properties ```json { "propertyUrls": [ "https://www.zillow.com/homedetails/property-1/", "https://www.zillow.com/homedetails/property-2/", "https://www.redfin.com/TX/Austin/property-3/" ], "estimatedRent": 3000, "downPaymentPct": 20, "mortgageRatePct": 7.25, "annualExpenses": 6000 } ``` #### Flip scenario (no rent needed) ```json { "propertyUrls": [ "https://www.zillow.com/homedetails/your-flip-property/" ], "estimatedRent": 0, "purchasePrice": 265000, "downPaymentPct": 100, "annualExpenses": 20000 } ``` *** ### Input Fields | Field | Type | Default | Description | |-------|------|---------|-------------| | `propertyUrls` | array | \[] | Listing URLs (Zillow, Redfin, Realtor.com) | | `searchUrls` | array | \[] | Search page URLs to batch-scrape | | `estimatedRent` | integer | 0 | Monthly rental income estimate ($) | | `purchasePrice` | integer | 0 | Override listing price (0 = use listed) | | `downPaymentPct` | integer | 20 | Down payment % (0-100) | | `mortgageRatePct` | number | 7.0 | Annual mortgage rate % | | `mortgageYears` | integer | 30 | Mortgage term: 10, 15, 20, 25, 30 | | `annualExpenses` | integer | 5000 | Annual non-mortgage costs ($) | | `useProxy` | boolean | false | Enable Apify proxy rotation | *** ### Output Example ```json { "property": { "address": "456 Oak Ave, Austin, TX 78701", "listingPrice": 385000, "beds": 3, "baths": 2, "sqft": 1850, "pricePerSqft": 208, "daysOnMarket": 12 }, "valuation": { "zestimate": 392000, "zestimateDeltaPct": 1.82, "taxAssessedValue": 310000, "priceHistory": ["Jul 2026 | Listed | $385,000", "Mar 2022 | Sold | $340,000"] }, "investment": { "monthlyMortgage": 2050, "monthlyOwnershipCost": 2467, "annualCashFlow": 4000, "breakEvenRent": 2467 }, "ratios": { "capRatePct": 7.43, "cashOnCashReturnPct": 5.19, "grossRentMultiplier": 11.46 }, "summary": { "investmentRating": "Good", "recommendation": "👍 Buy — solid investment", "cashFlowPositive": true } } ``` *** ### Supported Sources | Site | Listing | Pricing | Tax Data | Price History | |------|---------|---------|----------|---------------| | Zillow | ✅ | ✅ | ✅ | ✅ | | Redfin | ✅ | ✅ | ✅ | ✅ | | Realtor.com | ✅ | ✅ | ⚠ Partial | ⚠ Partial | | Generic sites | ✅ | ✅ | ❌ | ❌ | *** ### Pricing **$0.20 per property analyzed** - 5 properties = $1.00 - 25 properties = $5.00 - 100 properties = $20.00 All financial metrics included.
