Ledger Lane is Penny the Penguin’s little workshop of landlord tools: free calculators that run the numbers in seconds, printable kits that keep every tenant file tidy, and guides that answer the 2 a.m. questions. No accounts, no fluff — just the lines that matter.
One penguin, many workbenches. Everything below is live unless it says otherwise — and the “soon” shelves are honestly labelled, because dead links are worse than no links.
Eight browser-only calculators — cash flow & cash-on-cash, cap rate, rent increases, vacancy loss, late fees, deposit deductions, tenant screening and HELOC vs cash-out. Your numbers never leave your browser.
Open the calculators →The deal-question upgrade: a refinance break-even analyzer, a BRRRR analyzer, a 5-year rent-vs-hold projection, and CSV/PDF reports for all eleven tools. One payment, lifetime unlock, no subscription.
