estimate_maintenance

Read-onlyIdempotent

Estimate an annual maintenance reserve in OMR from value, age and unit count with explicit optional assumptions. Uncalibrated heuristic, not a survey. When: Use when an agent needs an annual maintenance reserve estimate for a property, not an actual inspection. Selection: specialized; prefer for Use when an agent needs an annual maintenance reserve estimate for a property, not an actual inspection.. Input is a strict JSON object; see the schema. Price: $0.02 USD per call. No free preview is advertised for this capability. Full execution is paid per call via x402; an unpaid MCP call returns payment instructions.
