How Can Investors Verify a Real Estate Sponsor's Claimed Project Costs?

Trace each material project cost from the approved scope to its contract, invoice, or payment record. A budget total alone does not show what has been spent, committed, or left open to change. Ask an independent construction professional to examine the quantities and pricing behind the sponsor's figures.

Reconcile the Budget to the Work

Request the detailed line-item budget, plans and specifications, contractor and subcontractor agreements, bids, change orders, invoices, lien waivers, draw requests, and proof of payment. Separate amounts already paid, contractually committed, bid but not contracted, and still estimated. Tie each material line to a defined scope and identify allowances without vendor support.

Compare the stated work with site conditions and inspection reports. Ask: "What work is excluded from this number?" "Which quantities have been measured on site?" "What change orders have been approved or are expected?" Have an independent construction professional compare the scope and pricing with contractor estimates. Where work is underway, request progress reports and confirm billed work is complete.

Check for Omissions and Classification Issues

Confirm that the budget accounts for permits, insurance, taxes, utilities, financing costs, site work, and known repairs. Review soft costs and carry costs through completion and lease-up. Compare repair and maintenance allowances with the asset's age and condition. Check that capital work is not presented as ordinary operating expense, or vice versa. Look for recurring costs omitted from the forecast.

Pay close attention to property tax assumptions after an acquisition, insurance costs, management fees, and reserves for future capital work. A self-managed property still has a management cost, even if no outside firm is paid. Ask for support for any unusually low cost assumption. If the sponsor's operating case depends on expense reductions, identify the action, responsible person, evidence that savings can be achieved, and expected timing.

Review Contractor Selection and Sponsor Fees

Request the bid comparison, selection rationale, and scope of each bidder. Ask the sponsor to disclose any relationship with a contractor. Compare construction management or development fees with the governing documents and contract. Confirm the fee basis and timing. Check whether change orders create additional fees. Related-party work calls for clear disclosure and independent review of pricing and scope.

Red flags include payments without invoice support, large deposits without matching progress, repeated change orders without a clear cause, missing lien waivers, and costs paid to an affiliate without competitive support. Ask who approves invoices. Check whether the person approving payment is independent of the vendor.

Stress the Remaining Exposure

Model costs above budget alongside a longer completion schedule. Show the resulting funding need, debt maturity exposure, and effect on lease-up and cash flow. Ask the sponsor how much contingency remains after known commitments and what happens if the largest unresolved scope grows. Keep a reconciliation for each major line showing its source document, payment status, remaining estimate, and open question. Review the construction budget and timeline alongside this cost review.

Checklist

• Obtain the line-item budget, plans, contracts, bids, and change orders.
• Reconcile paid and committed amounts to invoices and payment records.
• Match reported progress to completed work and lien waivers.
• Have an independent professional review scope and pricing.
• Identify omissions, recurring expenses, and unsupported allowances.
• Review affiliate relationships and fees, plus invoice approval controls.
• Model overruns and delays against available contingency and financing.
