Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Percent Funded % = (Current Reserve Bank Balance / Fully Funded Balance) × 100

Step-by-Step Mathematical Derivation

1
Fully Funded Balance (FFB) Actuarial Law

For each common asset (roof, elevator, pool), Fractional Depreciation = Current Age / Useful Life. Component FFB = Replacement Cost × Fractional Depreciation.

2
National Reserve Study Benchmark

Percent Funded = (Actual Balance / FFB) × 100%. < 30% = Poor / Critical Special Assessment Risk; 30%–69% = Fair; 70%–100% = Strong / Low Risk.

3
Homebuyer Mortgage Fannie Mae Guardrail

Following the Surfside condo collapse, Fannie Mae and Freddie Mac require HOAs to allocate at least 10% of annual budget to reserves, red-flagging underfunded communities.

Frequently Asked Questions

What happens if an HOA is less than 30% funded? +
Communities with under 30% reserves face massive risk of sudden special assessments ($10,000 to $50,000+ per homeowner) when roofs, elevators, or balconies fail, often causing mortgage lenders to blacklist the building.
What is an HOA special assessment? +
A special assessment is an emergency mandatory lump-sum bill charged to all homeowners in addition to monthly dues when the reserve fund has insufficient cash to cover major capital repairs.
