Free landlord tools
Every generator and calculator here runs in your browser — nothing you type is sent anywhere, and there is no signup. The state-aware tools are wired to the same verified statute records as the law pages — all 50 states — so what a tool tells you always matches what the law page cites.
- Security Deposit Return Letter Generates an itemized return letter with your state's deadline built in State-aware — all 50 states
- Rent Increase Notice Notice letter with your state's required notice period State-aware — all 50 states
- Late Fee Calculator Days late, grace-period check, and your state's cap rule State-aware — all 50 states
- Deposit Interest Calculator State and city deposit-interest math from the verified rate tables, with every year's rate cited State-aware — all 50 states
- Prorated Rent Calculator Partial-month rent under three proration methods
- Rental Profitability Calculator Cash flow, cap rate, and cash-on-cash return
The paid tools
Beyond the free tools, we sell two things. The state landlord kits are the documents you send — deposit return kits and lease disclosure packets built for each state from the same verified records as the law pages, every figure cited and dated, re-issued when the rule changes (deposit return kits $7.99 a state or $39 for all 50; lease disclosure packets $9.99 a state or $49 for all 50). The same page lists a lease agreement and a month-to-month rental agreement as all-50-state downloads ($5.99 each). The Landlord Operations Bundle ($14.99) is a rent ledger with IRS Schedule E expense tracking, a unit-turn workbook, a printable move-in/move-out inspection checklist, and six notice-letter templates. Everything on this page stays free; the paid tools cover the operational side the free tools don't.
Put these tools on your own site
Every free tool here is also embeddable — one line of HTML puts the working tool on your resource page, blog, or guide, free, with a small attribution link back here. Snippets and previews on the embed page.
How the state-aware tools work
The deposit letter, rent increase notice, and late fee tools read their deadlines, notice periods, grace periods, and cap rules from our state records — every state verified against official legislature sources, each with its own verified date. Details in how we verify.
