# Realy > Realy is a Chrome extension and analytics platform that instantly calculates Cash-on-Cash returns, Cap Rates, cash flow, and full ROI metrics for every Zillow listing — turning any property page into an underwriting workspace for real estate investors. Realy overlays institutional-grade investment math directly on Zillow's listing pages. Investors no longer need to copy data into a spreadsheet to evaluate a property: cap rate, cash-on-cash return, gross rent multiplier, net operating income, monthly cash flow, and 10-year projections are computed in real time using configurable assumptions (down payment, interest rate, vacancy, management, maintenance, insurance, taxes). Properties can be saved to a portfolio for side-by-side comparison and deeper analytics. The platform serves solo investors, real estate agents, and institutional acquisition teams who want fast, consistent underwriting without leaving the listing. ## Core pages - [Home](https://realy.app/): Product overview, hero demo, feature list, pricing teaser - [About](https://realy.app/about): Company mission, team, story behind Realy - [Pricing](https://realy.app/pricing): Plans for solo investors and institutional teams - [Sign In](https://realy.app/auth/signin): Existing user login - [Sign Up](https://realy.app/auth/signup): Create a new Realy account ## Legal - [Privacy Policy](https://realy.app/privacy) - [Terms of Service](https://realy.app/terms) ## Key concepts Realy computes - **Cap Rate**: Net Operating Income ÷ Purchase Price - **Cash-on-Cash Return**: Annual Pre-Tax Cash Flow ÷ Total Cash Invested - **Gross Rent Multiplier (GRM)**: Purchase Price ÷ Gross Annual Rent - **Net Operating Income (NOI)**: Gross Rent − Operating Expenses (excluding debt service) - **Debt Service Coverage Ratio (DSCR)**: NOI ÷ Annual Debt Service - **Cash Flow**: Monthly income after mortgage, taxes, insurance, vacancy, and maintenance reserves - **10-Year Projections**: Appreciation, equity buildup, cumulative cash flow, internal rate of return (IRR) ## Frequently asked questions **Do I need a Zillow account or any login?** No. Realy reads the public listing page you're already viewing — there's no account linking, no scraping of your Zillow profile, and no signup required to install the extension. **How does Realy estimate rent and expenses?** Rent starts from Zillow's Rent Zestimate as a baseline. Expense defaults — taxes, insurance, vacancy, management, maintenance, and CapEx — are layered on as percentages or fixed dollar amounts. Every value is editable per property. **Can I change the assumptions for my strategy?** Yes. Down payment, interest rate, loan term, vacancy, property management, repairs, and CapEx reserves are all editable. Set defaults once and Realy applies them across every listing automatically. **Does it work on Redfin, Realtor.com, or the MLS?** Today, Realy works on Zillow only. Redfin and Realtor.com support are on the roadmap. MLS integration isn't planned for the current beta. **Does it work for multifamily, short-term rentals, or flips?** Realy is built for buy-and-hold long-term rentals — single-family and small multifamily up to 4 units. STR (Airbnb) and flip analysis modes are on the roadmap. **What about commercial properties?** Not yet. Realy is focused on residential investment properties (1–4 units). Commercial isn't currently planned. **What happens to my lifetime access after the beta ends?** Lifetime means lifetime. The first 100 users who pay $99 get every current feature, every future feature, and every data add-on — at no additional cost, ever. **Is there a refund if it doesn't work for me?** Yes — 30-day no-questions-asked refund. Email hello@realy.app within 30 days for a full refund of the $99. ## Audience Real estate investors evaluating single-family rentals, small multifamily, and BRRRR opportunities.
