Use this site to decide whether to buy. Use other software to run what you already own. Built for 1–20 units, not a 200-door office.

• Landlord Math Calculator

  Screen a listing before you drive to it. You get monthly cash flow after vacancy, capex, and the mortgage — plus cash-on-cash, cap rate, DSCR, and a Buy / Thin / Pass verdict. Numbers stay in your browser. No account.

• Deal Analyzer Spreadsheet — $19

  Same math as the calculator, in Excel. Save the deal, run rent −10% and rate +1 point, print a one-page lender pack, and keep a 25-deal pipeline so this duplex is next to last month’s. Google Sheets: File → Import.

• State Landlord Kits

  The calculator tells you if the deal works. These kits are how you run the unit after you buy it — deposit clocks, condition reports, and letters. $9 per state, or $29 for all seven in the Southeast.

• Compare Rent Collection Apps

  Getting paid on the 1st is the difference between the spreadsheet and reality. Side-by-side chart of TurboTenant, Avail, Baselane, and Stessa — listings, screening, leases, rent, books, and banking.

• TurboTenant

  List the unit, take applications, run screening, and collect rent in one free-tier stack. Best first app if you own one to a handful of doors and do not want to pay for software before you have tenants.

• Stessa

  Connect the operating account and stop reconstructing the year from bank statements in April. Income, expenses, and Schedule E-style reports. Use this when the calculator said “buy” and you now have to keep books.

• Avail

  Leases, listings, and applications with a Realtor.com listing push. Consider it if you want a state-specific lease without paying a lawyer for the first draft — still have an attorney review before you sign anyone.

• Baselane

  Landlord banking plus rent collection plus bookkeeping. Useful if you still run rent through a personal checking account and want the operating money isolated without standing up a full property-management platform.

• Insurance Quote

  Do not type a guess into the calculator and call it underwriting. Call a landlord-policy broker. The premium and the dwelling limit belong on the insurance line, not a number you saw on a forum.
