About

Maven Cost Segregation: Tax Savings & Cash Flow Analyzer

Instantly analyze property tax savings and rental cash flow on Zillow, Redfin, and Realtor.com.

The Maven Cost Segregation extension is a professional-grade financial tool designed for real estate investors, CPAs, and tax strategists. It bridges the gap between a standard listing page and a deep-dive tax analysis, allowing you to instantly estimate the impact of Cost Segregation, Bonus Depreciation, and REPS (Real Estate Professional Status) on your next acquisition.

KEY FEATURES

Automatic Data Extraction: 
Seamlessly scrapes purchase price, monthly rent estimates, property taxes, and square footage from Zillow, Redfin, and Realtor.com.

Advanced Cost Segregation Engine: 
Dynamically reallocates building basis into 5, 7, and 15-year MACRS asset classes based on specific property types (Single Family, Multi-Family, Short-Term Rental, etc.).

Total Year 1 Deduction: 
Leads with the "Big Number"—the total accelerated depreciation deduction unlocked by your study.True Cash Flow Analysis: Calculates actual Net Operating Income (NOI) and True Annual Cash Flow by including 30-year fixed mortgage amortization (P&I) and Operating Expenses.

Interactive Assumptions Sandbox: 
A red-alert "Verify Assumptions" drawer lets you overwrite any scraped data, adjust down payment, interest rates, and land value percentages in real-time.

THE MATH BEHIND THE MAVEN STRATEGY

This tool utilizes standard accounting formulas to provide institutional-grade estimates:

Mortgage Amortization: 
$M = P \frac{r(1+r)^n}{(1+r)^n - 1}$ (Principal & Interest calculation).

MACRS Reallocation: 
Hardcoded asset class matrices derived from professional cost segregation case studies (e.g., allocating ~35% of basis to short-life assets for Short-Term Rentals).

Tax Savings Calculation: Projects net tax savings based on your marginal tax bracket and current Bonus Depreciation rules (100%, 80%, or 60% elective).

🏡 SUPPORTED PLATFORMS

Zillow (Auto-extract)
Redfin (Auto-extract)
Realtor.com (Auto-extract)

Manual Entry Mode: 
Use the extension as a universal real estate calculator on any website by manually entering values into the top-level drawer.

PRO-TIP: DATA LOADING

If you receive an error stating a site cannot be scraped, it may be due to the platform's "lazy-loading". Simply SCROLL down the property listing page OR REFRESH the page to ensure all data is loaded and try analyzing again.
