Guides
These are the long-form pieces behind the toolkit — the reasoning, the edge cases, and the arithmetic. Read them without buying anything.
The rent tracker spreadsheet that actually works
Why the month-grid everyone builds falls apart on partial payments and mid-year rent increases — and what to build instead.
Schedule E, line by line (2026)
Every expense line on Form 1040 Schedule E Part I, translated into the words your receipts actually use.
The 7 write-offs small landlords miss
Including the mileage math nobody does, and the repairs-versus-improvements line that costs the most to get wrong.
The one-page version
Every Schedule E line, the repairs-vs-improvements trap and the most-missed deductions, condensed onto a single printable page.
