Real Estate Profitability Analyzer

Unlock the full potential of your real estate investments with the Real Estate Profitability Analyzer. This Chrome extension seamlessly integrates with Zillow for-sale listings to provide instant profitability insights. Whether you are an investor or a real estate enthusiast, this tool helps you quickly analyze properties for their potential return on investment.

Key Features:

Automatic Data Fetching: Pulls key data from Zillow for-sale listings, including price, rent Zestimate, address, beds, baths, square footage, and property details.

Profitability Metrics: Calculates essential metrics such as Cap Rate, Cash-on-Cash Return, and Net Operating Income (NOI) to give you a clear picture of the property’s financial performance.

Mathematical Functions:

• Net Operating Income (NOI): Calculates the annual effective income (rent minus vacancies) minus operating expenses (assumed as a percentage of gross income). This helps determine the property's ability to generate profit.
Formula: NOI = (Annual Rent × (1 - Vacancy Rate)) - Operating Expenses

• Cap Rate: Measures the annual return on investment based on the NOI and property price, expressed as a percentage.
Formula: Cap Rate = (NOI / Property Price) × 100

• Cash-on-Cash Return: Evaluates the return on cash invested (down payment) by considering the annual cash flow after mortgage payments.
Formula: Cash-on-Cash Return = (Annual Cash Flow / Down Payment) × 100

• Mortgage Calculation: Uses the standard mortgage formula to compute monthly payments based on loan amount, interest rate, and loan term.
Formula: Monthly Payment = [Loan Amount × (Monthly Interest Rate × (1 + Monthly Interest Rate)^N)] / [(1 + Monthly Interest Rate)^N - 1]

Editable Rent Zestimate & Rental Estimate: Both the Rent Zestimate (in property details) and the Rental Estimate (in investment metrics) are fully editable. Click to change the value and see all metrics recalculate instantly—no need to refresh. Perfect for testing different rent scenarios against local market projections.

User Preferences: Customize your analysis with your own assumptions. Set Vacancy Rate, Operating Expense Ratio, Down Payment Ratio, Interest Rate, and Loan Term. Save your preferences and they persist in your browser—no account or login required.

Profitability Classification: Classifies the property as "Highly Profitable," "Moderately Profitable," "Potentially Profitable," or "Potentially Unprofitable" based on Cap Rate and Cash-on-Cash Return thresholds.

Easy-to-Use Interface: Clean popup displays all property data and investment metrics. Works on Zillow single-property listing pages (not search results). Accurate parsing of formatted prices (e.g. "Est. $102,600") so calculations stay correct.

Works Only on Zillow For-Sale Listings: The Real Estate Profitability Analyzer is designed to work exclusively with Zillow's for-sale listings, ensuring you're analyzing only relevant investment opportunities.
