Real Home Cost — Homebuyer Lens for Zillow

Description

Real home cost tool for Zillow: first-year forecast, age-based risks, red flags, and true monthly cost. See what a Zillow listing really costs to own, before you buy it. Homebuyer Lens is a free Chrome extension for first-time homebuyers. It reads every Zillow listing and shows you the numbers Zillow does not: the true cost of owning that specific house in its first year, the risks common to its era, and the top mistakes it is set up to trigger. WHAT YOU GET ON EVERY ZILLOW LISTING ▸ First-Year Maintenance Forecast Based on the home's age, size, and condition signals in the listing. Uses 2026 US average repair costs adjusted for property age. A 1998 home in decent shape forecasts very differently than a 1962 home sold as-is, and the panel shows you the difference. ▸ True Monthly Cost Stack Zillow shows you mortgage. That is it. The panel stacks mortgage + property taxes + 2026 insurance average + monthly maintenance reserve, so you see what the house actually costs you every month. Every number cites its data source: Federal Reserve, Insurance Information Institute, HomePlaybook. ▸ Age-Based Risk Profile Twelve statistical risk patterns keyed to the year the home was built. A pre-1970 home flags likely galvanized plumbing and knob-and-tube wiring. A 1978 to 1995 home flags polybutylene pipes. A pre-1978 home flags lead paint. A pre-1980 home flags asbestos. These are patterns for the era, not property-specific findings, so you walk into your inspection knowing exactly what to check. ▸ Listing Red Flag Detection Scans the listing description for language that signals expensive problems: Sold as-is and cash only Original roof, HVAC, windows, or plumbing Fixer-upper and handyman special Knob-and-tube wiring, aluminum wiring, galvanized pipes, polybutylene Motivated seller, short sale, foreclosure Positive signals get counted too. Recent roof, new HVAC, updated electrical are flagged as risk-reducers and adjust the forecast down. ▸ Top 3 $5K Mistakes To Watch Ranked heuristics from the HomePlaybook 47-mistake catalog. Different aged homes surface different mistakes. A 1955 home leads with electrical concerns. A 1982 home leads with basement moisture and foundation settling. The top 3 you see are the most likely surprise problems for a home of that specific age. ▸ Save And Compare Up To 20 Homes Save any listing to your local list. Open the compare dashboard to see up to four saved homes side-by-side: forecasts, monthly costs, listing red flags, age-based risks, and top mistake per property. Everything stays in your browser. WHO IT IS FOR First-time homebuyers. People about to make the largest purchase of their lives who have never owned property and do not know what a 1970s water heater actually costs to replace, or that "sold as-is" language is not a negotiating tactic. It is a signal. If you already own several properties, this is not built for you. If you are buying your first, second, or maybe third home, this is exactly for you. PRIVACY FIRST Zero personal data collected by default. No account. No login. No signup. All forecast calculations happen locally on your device. Your saved homes list is stored in your browser's local storage and never uploaded anywhere. The only data transmission the extension ever makes is if you choose to submit your email address to receive our free $5K Mistake Checklist. That email goes directly to our email service provider (Brevo). It is not shared with any third party, and you can unsubscribe from any email in one click. DATA SOURCES CITED IN THE PANEL Mortgage rate: Federal Reserve 2026 average Property taxes: 1.1% national average Insurance: Insurance Information Institute 2026 average Maintenance forecast: HomePlaybook 47-mistake catalog and 2026 US repair costs Every number in the cost stack shows its source inline. Nothing is invented. WHAT HOMEPLAYBOOK IS HomePlaybook is a homeowner education brand. The forecast logic, mistake catalog, and age-based risk patterns come from the same system we sell as the HomePlaybook Mastery guide, a $44 12-month maintenance playbook for first-time owners. This free extension is the pre-purchase version of that system, delivered at the moment you actually need it: when you are looking at a house you might buy. CURRENT LIMITATIONS Works on Zillow listings only. Redfin and Realtor.com support planned. Estimates use national 2026 averages. Regional variance is real, and your actual costs will differ. Not financial or legal advice. Always get a professional home inspection. IMPORTANT — PLEASE READ This extension provides estimates for educational purposes only. It is not a substitute for a professional home inspection, appraisal, mortgage quote, insurance quote, tax opinion, legal advice, or financial advice. All figures are based on 2026 US national averages and vary significantly by region and specific property. Age-based risks are statistical patterns for the era, not verified findings for any specific home. Listing red flag detection depends entirely on what the seller chose to disclose in the description. Absence of flags does not mean absence of problems. Before making any offer or buying decision, you must engage a licensed home inspector, mortgage lender, insurance provider, real estate attorney, and financial advisor. HomePlaybook accepts no liability for decisions made in reliance on this extension. Your use of the extension constitutes acceptance of our Terms of Service.
