    Where the money goes

    Monthly operating expenses + debt service.

    Rent sensitivity

    Rent is the most-fudged number in every analysis. Here's the verdict if you're off by 15% either way.

    Long-term outlook

    Appreciation, sale proceeds, IRR and tax — the hold-for-years view. Rough estimates, not tax advice.

    How it works

    Three steps. No account, no spreadsheet.

    1. Enter the deal. Price, rent, expenses, financing — or flip numbers (price, rehab, ARV). Everything updates live.
    2. Get the verdict. Instant cash flow, cap rate, cash-on-cash, DSCR, IRR and a Strong / Review / Weak call — measured against criteria you set yourself.
    3. Export the report. One click turns it into a clean PDF you can send a partner or lender. $5 once, free analysis forever.

    Questions

    How is this better than a spreadsheet?

    Speed and the verdict. Spreadsheets make you build the formulas and interpret them yourself; DealLens gives you the numbers plus a Strong / Review / Weak call with the reasoning spelled out — in about a minute.

    What do I get for $5?

    The PDF report: a clean, professional one-pager with the verdict, all key metrics, the expense breakdown, and your assumptions — ready to send a partner, agent, or lender. The analyzer itself stays free.

    Is this financial advice?

    No. DealLens is an estimation tool. It can't see the roof, the tenants, or the neighborhood. Always do your own due diligence before buying a property.

    Does it work for cash purchases?

    Yes — tick "Cash purchase" and the financing section disappears. DSCR doesn't apply without debt, and the verdict adjusts accordingly.
