# AppFolio Cost Tuning ## Overview AppFolio Stack API pricing is partner-agreement based, with costs scaling by API call volume per managed property. Property management portfolios generate high-frequency reads for tenant lookups, lease status checks, and maintenance requests. Each redundant API call erodes margin on per-unit revenue. Optimizing call patterns directly impacts operational profitability, especially for portfolios managing hundreds or thousands of units where even small per-call costs compound rapidly. ## Cost Breakdown | Component | Cost Driver | Optimization | |-----------|------------|--------------| | Property/unit reads | Per-call pricing on tenant and unit endpoints | Cache with 10-15 min TTL; property data changes infrequently | | Lease operations | Bulk lease queries across entire portfolio | Fetch all leases once, filter locally instead of per-unit calls | | Maintenance requests | Polling for new work orders | Use webhooks to receive push notifications | | Reporting exports | Large payload downloads for financial reports | Schedule off-peak, cache results for 24h | | Vendor/owner lookups | Repeated lookups for the same contacts | Build a local lookup table, refresh daily | ## API Call Reduction ```typescript class AppFolioCache { private cache = new Map<string, { data: any; expiry: number }>(); get(key: string): any | null { const entry = this.cache.get(key); if (!entry || Date.now() > entry.expiry) return null; return entry.data;...
