OwnerReach — Find Property Owners on Zillow

Find property owner phone & email on Zillow listings. Instant cap rate, cash flow, and ROI calculator for real estate investors.

OwnerReach — Find Property Owners on Zillow Stop guessing if a rental property is a good deal. Start knowing in seconds. You found a listing on Zillow. The price looks reasonable. The photos look good. But is it actually a good investment? You open a spreadsheet, start punching in numbers — mortgage payment, property tax, insurance, vacancy, maintenance — and 20 minutes later you're still not sure if the math is right. That's the problem. Zillow gives you listing data, but not investment data. And running the numbers manually for every property you look at is slow, tedious, and error-prone. OwnerReach fixes that. WHY ANALYZING ZILLOW DEALS IS SO HARD Zillow shows you price, photos, and basic details. But it doesn't tell you: - What your actual monthly cash flow would be after all expenses - Whether the cap rate meets typical investor thresholds - How much total cash you need to close the deal - Whether the property passes the 1% rule - What your cash-on-cash return looks like with your specific financing terms Most investors either skip the math entirely and go with gut feel, or spend 15-20 minutes per property in a spreadsheet. Neither approach scales when you're scanning dozens of listings per week. OwnerReach runs the full analysis in seconds — right on the Zillow page you're already looking at. WHAT THIS EXTENSION DOES OwnerReach is an investment calculator that lives directly on Zillow. When you open any property detail page, it reads the listing data automatically and lets you analyze the deal without leaving the page. No spreadsheets. No formulas. No copy-pasting numbers between tabs. Here's what you get: Auto Data Extraction — OwnerReach reads the purchase price, Rent Zestimate, property tax, HOA fees, bedrooms, bathrooms, square footage, and year built directly from the Zillow listing. Everything fills in automatically. Floating Calculator Panel — A compact calculator appears on the Zillow page itself. Adjust rent, down payment percentage, and interest rate. Click Analyze Deal to see your key metrics instantly without leaving the listing. Full Side Panel — Click to open a detailed calculator with every input you need: financing terms, closing costs, insurance, maintenance reserve, vacancy rate, and property management fee. All adjustable. All with sensible defaults. Deal Verdict Scoring — Every analysis gets a clear verdict: Great Deal, Decent, or Weak Deal. The scoring is based on four investment signals: cap rate, cash-on-cash return, the 1% rule, and positive monthly cash flow. Monthly Expense Breakdown — See exactly where your money goes each month: mortgage principal and interest, property tax, HOA, insurance, maintenance, and management. Income versus expenses, clearly laid out. Investment Summary — Total cash needed to close, loan amount, down payment, closing costs, and net operating income. Everything you need to decide if this deal is worth pursuing. HOW IT WORKS 1. Install OwnerReach and go to any property on zillow.com 2. Open a property detail page — the floating calculator appears automatically 3. The listing price, estimated rent, tax, and HOA are already filled in 4. Adjust any inputs if needed — down payment, interest rate, rent estimate 5. Click Analyze Deal — see Cap Rate, Cash Flow, Cash-on-Cash, and the 1% Rule instantly 6. Click Open Full Calculator for the detailed side panel with monthly breakdown That's it. What used to take 20 minutes in a spreadsheet now takes 10 seconds on the page. WHY A SIDE PANEL INSTEAD OF A POPUP Most Chrome extensions use a tiny popup window. That works for simple tools, but investment analysis requires space — you need to see multiple inputs and detailed results at the same time. OwnerReach uses Chrome's side panel, which stays open alongside the Zillow page. You can scroll through the listing while reviewing your analysis. No switching between windows. No cramped popup that disappears when you click elsewhere. The floating panel on the page gives you quick results. The side panel gives you the full picture. Both work together. ANALYSIS HISTORY Every deal you analyze is saved to your local history. You can review past analyses, compare properties, and track which listings you've already evaluated. History is stored locally in your browser. Nothing is sent to any server. You can clear it anytime. REAL SCENARIOS WHERE THIS HELPS Scanning Zillow for rental properties: You're browsing Zillow looking for your next rental investment. Instead of bookmarking 30 listings and analyzing them later in a spreadsheet, you evaluate each one in real time as you browse. In 10 minutes, you've screened a dozen properties and identified three worth investigating further. Evaluating a deal from your agent: Your agent sends you a Zillow link and says "this one looks interesting." You open it, OwnerReach pulls the data, you adjust the rent estimate based on your local knowledge, and in 15 seconds you know the cap rate is 3.2% — below your 5% minimum. You pass and move on. Comparing financing scenarios: You're looking at a $350,000 property and wondering whether to put 20% or 25% down. You run the analysis twice with different down payment percentages and instantly see how it changes your monthly cash flow and cash-on-cash return. House hacking a duplex: You found a duplex on Zillow for $420,000. You plan to live in one unit and rent the other. You enter the rent for one unit as your monthly rent input and see whether the rental income covers enough of the mortgage to make it worth it. BRRRR strategy analysis: You're evaluating a property for a Buy-Rehab-Rent-Refinance-Repeat strategy. You enter your expected after-repair value as the purchase price and your target rent. The cash-on-cash return tells you if the deal pencils out after refinancing. Wholesaling property screening: You're scanning Zillow for properties that might work as wholesale deals. The 1% rule check and cap rate give you a quick filter. If a property doesn't pass basic investment thresholds, you skip it immediately instead of spending time on deeper analysis. WHAT THIS EXTENSION DOES NOT DO OwnerReach does not scrape, export, or download any data from Zillow. It reads the listing page you already have open in your browser — the same data you can see with your own eyes. OwnerReach does not access your Zillow account, your login credentials, or any personal information. OwnerReach does not send your browsing data, search history, or analysis results to any external server. All calculations run locally in your browser. The only permissions it uses: - storage — to save your analysis history and daily usage count locally on your device - sidePanel — to open the full calculator panel alongside the Zillow page - activeTab — to read listing data from the Zillow page you're currently viewing - host_permissions (zillow.com) — required for the content script that extracts listing data from Zillow property pages No tracking. No analytics. No data collection. The extension works entirely offline after installation. FREE TIER OwnerReach is free to use with 5 deal analyses per day. The counter resets every day at midnight. For most casual investors browsing Zillow a few times a week, 5 per day is plenty. You can see your remaining count at the top of the side panel. THE MATH BEHIND THE ANALYSIS Every metric is calculated using standard real estate investment formulas: Monthly Mortgage (P and I) = P x [r(1+r)^n] / [(1+r)^n - 1], where P = loan amount, r = monthly interest rate, n = total payments Effective Monthly Rent = Monthly Rent x (1 - Vacancy Rate) Monthly Cash Flow = Effective Rent - Mortgage - Tax - HOA - Insurance - Maintenance - Management Cap Rate = Net Operating Income / Purchase Price x 100 Cash-on-Cash Return = Annual Cash Flow / Total Cash Invested x 100 GRM (Gross Rent Multiplier) = Purchase Price / Annual Gross Rent 1% Rule = Monthly Rent / Purchase Price. Passes if >= 1% Total Cash Needed = Down Payment + Closing Costs Default assumptions: 20% down payment, 7% interest rate, 30-year term, 3% closing costs, 5% vacancy rate, 1% annual maintenance, 0% management fee. Insurance estimated at 0.35% of purchase price if not specified. All defaults are adjustable. No hidden logic. No proprietary adjustments. The same formulas taught in every real estate investing course.
