A family office CFO has 9 operating businesses, 32 leases, and no current view into whether the consolidated CAM and reconciliation spend is correctly billed. The family has worked with a CPA for 15 years on bookkeeping and tax, but the CPA does not audit reconciliations against leases. The estate counsel handles transactional real estate work but does not run reconciliation audits. The CFO knows there is leakage in the portfolio. They do not know how much, and they do not have a way to surface it without committing to a six-month consulting marathon.
I built CAMAudit because that engagement structure does not work for family offices. The principal wants results in weeks, not quarters. With the platform handling per-property audit production, a 32-lease portfolio audit becomes a 6- to 8-week project. The bottleneck moves from analysis to principal-facing presentation, which is exactly where partner judgment matters most.
This is the playbook.
What a family office lease audit is
A family office lease audit is a coordinated review of every lease and reconciliation across the operating businesses the family controls, run as a single engagement under the family office umbrella. The deliverables:
Per-property findings report. Lease summary, expense pool analysis, the 14 detection rules applied, dispute letter draft if overcharges exist.
Portfolio rollup. Aggregated view across the cohort — total recoverable dollars, distribution by detection rule, geographic and entity-level concentration, units with highest exposure.
Recovery roadmap. Prioritized list of disputes to pursue, expected timeline per dispute, and the principal-facing summary of next steps.
The scope difference from a single-building audit is that the engagement spans entities. A property under one operating company is on a retail anchor lease; another is on a warehouse triple-net; a third is an urban office sublease. Each has different lease structures and different overcharge patterns. The portfolio approach captures the full picture rather than spot-checking one building at a time.
The family office services overview frames the audit inside the broader CRE service line. This article focuses on the audit engagement itself.
How partners run the audit
Phase 1, weeks 1-2 — kickoff and inventory:
Engagement letter signed at the family office level. Portfolio inventory pulled — list of all leases across all operating companies, current occupants, lease term, expiration date, last reconciliation received, prior-year statements available.
Single secure intake. Family offices reluctantly share data; do not multi-thread the document collection. One intake page, one upload location, one point of contact at the family office side.
Phase 2, weeks 3-6 — audit production:
Bulk upload to CAMAudit. Tag each property by operating company. The platform runs Textract extraction, classification, and the 14 detection rules in parallel.
Per-property review. The platform's outputs are deterministic on math rules and probabilistic on classification rules — spot-check the latter. Average review time is 30 to 60 minutes per property depending on lease complexity.
Edge case handling. Roughly 15 to 20 percent of family office portfolio properties have a complication: missing prior-year data, ambiguous lease language, sale-leaseback structures that complicate the expense pool. Allocate week 6 for second-pass work.
Phase 3, weeks 7-8 — deliverables:
Per-property reports and dispute letter drafts finalized. CAMAudit generates the report and letter; you customize the cover, tone, and signature block to match the operating company's relationship with each landlord.
Portfolio rollup deck. 12 to 18 slides showing aggregated findings, recovery roadmap, and prioritization.
Principal presentation. 60- to 90-minute walkthrough with the family office CFO and (often) the principal directly. This is the conversation that determines whether you become the recurring CRE reporting provider or stay a one-time engagement.
What it costs and pays
A 30-lease family office portfolio audit typically prices as a project plus contingency:
Project fee. $1,000 flat per lease (30 × $1,000 = $30,000) covers your audit and review time regardless of recovery outcome.
Contingency. 25 percent of recovered dollars. Industry-typical recovery rate when overcharges exist runs $4,000 to $7,000 per lease on average across CAM, taxes, and insurance. At $5,000 average and 70 percent clearance: 30 × $5,000 × 0.7 × 0.25 = $26,250.
Total year-one revenue: $56,250 from the audit alone.
Software cost on CAMAudit is sub-$50 per audit at the 5-pack tier. On 30 leases: $1,500.
Net before partner time: $54,750 in year one. Partner time investment is roughly 50 to 80 hours across the 8-week engagement, putting effective hourly rate well above $500 even before the recurring retainer the audit usually opens up.
The advisor fee comparison walks through how to structure the project versus retainer versus contingency mix across these engagements.
What family office audits surface that other audits miss
Three patterns show up disproportionately in family office portfolios:
Multi-entity expense allocation errors. When the family controls multiple operating companies and some share landlord-managed properties, the pro-rata share calculations can be wrong in ways that single-tenant audits do not surface. Each entity's share is computed against a different denominator depending on how the property is leased.
Sale-leaseback CAM ambiguity. Family offices often hold real estate in one entity and operate from it through another (a captive sale-leaseback structure). The CAM and operating expense passthrough between the property entity and the operating entity can be miscalculated in ways that look like internal accounting but actually involve a third-party landlord on a portion of the property.
Long-tenure base year drift. Family-owned operating companies tend to occupy their spaces for long stretches. Base year errors compound over 10 to 20 years of occupancy, and most CFOs have never reset the base year analysis since the original lease signing. The audit recovers material dollars from this alone.
The pitch sequence covers how to surface these patterns during the initial conversation. The portfolio benchmarking article covers the occupancy cost analysis that often runs alongside the audit.
Where CAMAudit fits
The platform handles the audit production phase end to end.
Per property: lease and reconciliation upload. Textract extraction. Classification of expense lines. Application of the 14 detection rules. Dispute letter draft generation.
Across the portfolio: rollup view aggregating findings, recovery prioritization, distribution analysis. This is the artifact that anchors your principal presentation and that re-uses across the CRE reporting cadence in subsequent quarters.
Branding: white-label at /partners/white-label replaces CAMAudit's branding with your firm's. For family office engagements this is required, not optional — the principal sees your firm's deliverable.
Alternative model: revenue-sharing at /partners/revenue-sharing refers individual operating companies directly to CAMAudit and pays you commission. This is rare in family office work because the principal is usually buying a single, branded engagement, but it can fit when one operating company has a one-off audit need outside the broader portfolio scope.

Closing CTA
Family office lease audit is the engagement that opens the recurring CRE retainer. The audit pays for itself in year one through recoveries; the relationship pays for years through quarterly reporting and project add-ons.
Run a free audit at /scan, then look at white-label for principal-facing branded delivery or revenue-sharing for referral commission. The first family office you close turns into a multi-year partnership.
Frequently Asked Questions
What is a family office lease audit?
A family office lease audit is a coordinated review of every lease and CAM reconciliation across the operating businesses a family controls. The deliverable is a per-property findings report, a dispute letter draft where overcharges exist, and a portfolio rollup that ties the recovery picture back to the consolidated financials. The audit usually covers 20 to 60 leases across 5 to 15 entities and runs 6 to 10 weeks end to end.
How do partners actually run a family office lease audit?
Partners engage at the family office level, get a portfolio inventory of leases and operating companies, collect documents through a single secure intake, and run the full set through CAMAudit. The platform handles extraction and the 14 detection rules per property. Partners spend their time on principal-facing deliverable formatting, dispute letter customization, and the rollup presentation. The cadence is annual or biennial in mature engagements.
What does a family office lease audit cost or pay?
Most partners price family office audits as a project with a contingency component. Project fee runs $30,000 to $100,000 depending on portfolio size, plus 20 to 30 percent of recovered overcharges. A 30-lease portfolio at $1,000 flat plus 25 percent on $105,000 of expected recoveries yields roughly $56,000 to the partner in year one. Software cost on CAMAudit is sub-$50 per audit at pack tiers.
Where does CAMAudit fit into a family office lease audit?
CAMAudit runs the per-property audit production. The 14 detection rules cover CAM caps, controllable caps, gross-up, pro-rata share, base year, management fee, and the classification overcharges across insurance, taxes, utilities, and landlord overhead. White-label produces principal-facing deliverables under your firm's brand. The platform also generates the portfolio rollup that anchors your year-end principal presentation.
