Property budget flux analysis for the S.L. Nusbaum RealPage portfolio. Scope is over-budget expense lines only: income and non-operating income accounts, payroll accounts and management fees are excluded by design, and a line must have actual spend above budget before it can flag — over 10% of budget, sign switch, or unbudgeted activity. Stage 1 rules gather the evidence free: T12 monthly pattern, GL line items grouped by document, AP rows with bill-to-post lags. Every flagged line then goes to Claude Haiku (temperature 0) with its full evidence pack, which writes the variance commentary the way a junior accountant would for management review — what drove the overspend and the action to take. Upload the JCF financial package (or the Income Statement with Budget Comparison + Monthly Spread), the GL export, and the AP register — one property or the whole portfolio at once.
