Frequently Asked Questions
About extraction, analysis, supported platforms, metrics, and privacy.
What does Deal Analyzer do?+
Deal Analyzer is a Chrome extension for rental property screening. Open a Zillow or Redfin listing, review the extracted property details, adjust your assumptions, and see key investment metrics such as cash flow, cap rate, cash-on-cash return, DSCR, the 1% rule, and break-even occupancy.
Which platforms are supported?+
Deal Analyzer works on Zillow and Redfin property listing pages in Chrome on desktop. It is designed for quick single-property analysis while you browse listings.
Is it free?+
Yes. The free workflow includes property data extraction, adjustable assumptions, core investment metrics, basic formula visibility, CSV export, and recent deal history. Pro adds power-user tools such as formula breakdowns, sensitivity analysis, deal comparison, extended history, Google Sheets sync, custom defaults, and auto-open.
Do I need to create an account?+
No account is required to use the free analysis workflow. If you upgrade to Pro, Deal Analyzer may use a product ID or account connection to verify your Pro status. Recent deal history and settings are stored in your browser.
What property data does it use?+
Deal Analyzer uses listing data available on the Zillow or Redfin page, such as price, beds, baths, living area, year built, property tax, HOA when listed, lot size, and days on market. Some listings may not include every field, so you should review the extracted details before relying on the analysis.
What is the difference between Living Area and Lot Size?+
Living Area is the interior home size, shown in square feet. Lot Size is the land parcel size. Small lots are usually shown in square feet, while larger parcels are shown in acres. Deal Analyzer keeps fixed-unit values for exports so spreadsheet columns do not mix units.
What if HOA is blank or shown as --?+
If HOA is not listed on the property page, Deal Analyzer treats it as $0 per month for the calculation. That does not guarantee the property has no HOA fee. If HOA matters for the deal, verify it separately and adjust your assumptions before making a decision.
Which investment metrics does it calculate?+
Monthly mortgage payment (P&I), total monthly expenses, monthly and annual cash flow, cap rate (NOI / price), cash-on-cash return (annual CF / down payment), 1% rule (rent / price), break-even occupancy, and DSCR (NOI / annual debt service). Each metric is color-coded as good, marginal, or bad.
Can I adjust the assumptions?+
Yes. You can change down payment percentage, interest rate, loan term (15 or 30 years), estimated monthly rent, insurance, maintenance reserve, vacancy rate, and property management fee. Results update in real time as you adjust.
What is the sensitivity table?+
The Pro sensitivity table shows how cash-on-cash return changes when rent and interest rate assumptions move. Rent is shown from 80% to 120% of your current rent assumption, and interest rates are shown around the rate you entered. Each cell is color-coded so you can quickly compare scenarios.
Can I send deals to Google Sheets?+
Yes. Pro users can sync analyzed deals to Google Sheets. The sheet uses separate columns for living area, lot size in square feet, lot size in acres, and display text, so your spreadsheet stays clean for sorting, filtering, and formulas.
How does deal comparison work?+
The free tier saves up to 5 recent analyzed properties. Pro extends history to 20 properties and unlocks the Compare tab, which shows up to 3 deals side by side with address, price, and analysis date.
Does it work on mobile?+
Deal Analyzer is designed for Chrome on desktop. Mobile browsers usually do not support the same extension side panel experience, so mobile use is not supported for the first release.
Are the numbers investment advice?+
No. Deal Analyzer is a screening and calculation tool. It helps you organize assumptions and compare scenarios, but it is not financial, legal, tax, or investment advice. Always verify listing data, rent estimates, financing terms, taxes, HOA, insurance, and local rules before making an investment decision.
Is this affiliated with Zillow or Redfin?+
No. Deal Analyzer is an independent browser extension. It is not affiliated with, endorsed by, or connected to Zillow Group, Redfin, or any real estate platform.
