Expense Pool Mismatch Calculator

Leases vary on what's billable. This calculator flags landlord exposure.

Total billable expense

Absorbed % of billable

2.80%

How the math works

Legacy leases × mismatch categories / tenant count = landlord gap exposure.

Portfolio operating cost absorbed due to expense pool mismatch commonly runs 1-3% of total billable. On $1.65M billable, that's $15-50k/yr of quiet margin leak. Worth a one-time clean-up: map each lease, build category matrix, enforce at billing.

How to Use

Enter total billable expense.
Enter tenant count.
Enter mismatched categories dollar.
Enter legacy lease count.
Read landlord absorbed amount.

Frequently Asked Questions

Typical mismatches?

Older leases may exclude: roof repairs, HVAC replacement, parking lot maintenance, reserve funding, management fees above X%, real estate taxes. Newer leases broader. Result: some tenants billed, some not, landlord covers gap.

Audit exposure?

Billing category excluded in a tenant's lease but charged anyway creates refund liability. Audits often expose this. Portfolio-wide fix: map categories lease-by-lease, bill only what's permitted, create spreadsheet trail.

Renewal solution?

At lease renewal, align language to current portfolio standard. Legacy exemptions disappear if tenant doesn't specifically renew them. Slow multi-year process but cleans up pool mismatch over time.
