Underwrite commercial construction debt as a sequence from closing through work, occupancy, cash-flow stabilization, and final repayment or conversion. A commitment funds an approved project under conditions; it does not guarantee that the budget is sufficient or that a permanent loan will repay it.
Connect scope, schedule, equity, draws, interest, contingencies, leases, and exit underwriting in one model. The most consequential mistakes often occur between those schedules: work needs payment before a draw, interest consumes a capital allowance, or physical completion arrives before the income required for conversion.
Define the construction and operating milestones
Identify acquisition, design, entitlements, permits, start, major trade completion, inspections, tenant delivery, occupancy, paid rent, stabilization, and maturity. Assign responsible parties and evidence required for each.
Separate legal permission to build, physical progress, and income performance. They are related but different. A finished building may remain vacant, and a signed lease may not produce cash until delivery and concessions are complete.
For a Chicago-area project, establish the exact jurisdiction and actual approval path. Do not assume a metropolitan label supplies a reliable permit duration. Obtain property-specific professional input and reflect unresolved approvals in the schedule and decision conditions.
Build the total project budget
A hypothetical project has the following uses. The amounts are illustrative and do not establish local construction costs or financing terms.
| Use | Amount |
|---|---|
| Land or acquisition | $2,000,000 |
| Hard construction | $5,000,000 |
| Design, professional, and other soft costs | $1,000,000 |
| Financing and carrying allowance | $500,000 |
| Construction contingency | $500,000 |
| Leasing and operating support | $1,000,000 |
| Total project uses | $10,000,000 |
Assume debt commitment is $6 million and equity is $4 million. Sources equal uses. The loan is 60% of the stated total cost, but actual eligible-cost rules, value tests, reserves, and advance conditions still require approval.
The financing allowance must identify interest, fees, and other costs rather than serve as a balancing plug. The leasing allowance must include the actual delivery and concession economics. A complete total can still conceal missing scope if categories are vague.
Model equity funding order and draw availability
Assume, solely for illustration, the lender requires the first $4 million of qualifying costs to be funded by equity before its $6 million is advanced. That produces a different liquidity schedule from a pro rata funding structure.
Confirm treatment of land equity, pre-closing costs, deposits, related-party fees, change orders, and overruns. A cost counted in the investor’s total budget may not count toward the lender’s equity requirement.
Identify who pays contractors first and when reimbursement arrives. Draw inspection, documentation, retainage, and lien-related conditions can require temporary cash. The model should show peak funding, not merely final debt and equity totals.

Forecast interest from the actual balance path
Assume an 8% annual rate and quarterly average drawn balances of $1 million, $2.5 million, $4 million, and $5.5 million during the first year. Using a simplified quarter-year calculation, interest is $20,000, $50,000, $80,000, and $110,000, totaling $260,000.
This illustrates why interest on the final commitment for the entire year can differ from actual drawn-balance interest. It also shows why delay matters: balances tend to remain elevated while the project waits for completion or rent.
Actual daily accrual, fees, minimum interest, rate changes, capitalization, and draw dates can change results. Reconcile the budget to statements. If interest draws consume commitment originally expected for construction, identify the resulting scope-funding gap.
Keep cost-to-complete current
At each draw, reconcile original budget, approved changes, costs incurred, payments, remaining committed work, forecast additional costs, contingency remaining, undrawn funds, and available equity. A percentage-complete report alone does not establish financial completion.
Suppose remaining construction and soft-cost obligations are $2 million, but only $1.6 million of permitted loan funds and $150,000 equity remain. The gap is $250,000. It needs a source before further commitments are made.
Do not preserve the original contingency after approved changes have used it. Track an actual balance and distinguish committed contingency from cash already spent. Also include operating and interest effects of a delay rather than only contractor price increases.
Review the contract and completion support
Understand the contractor agreement, scope, exclusions, allowances, schedule, change-order process, security, and completion obligations. A fixed price can still contain exclusions or assumptions that leave the owner exposed.
Review guaranties, indemnities, and borrower obligations separately. ACRES’s 2025 filing provides a primary example of distinct completion and carrying-cost commitments in an actual transaction. It does not define the terms of this hypothetical project. ACRES guaranty disclosures
Document who funds an overrun and what approvals are required. A guarantor’s willingness to support a project is not the same as cash committed on a particular date. Incorporate the obligation and capacity into the investment decision.
Lease-up is part of construction financing
Model tenant improvements, commissions, free rent, operating expenses, and collections during occupancy growth. A building can be physically complete while producing insufficient income for the takeout.
Use lease-by-lease dates for commercial property. A single industrial tenant or office floor can materially change the project. A smooth annual occupancy curve can conceal the actual all-or-nothing timing of major leases.
Show the evidence level: signed leases, proposals, broker assumptions, and speculative future tenants. Do not describe a property as stabilized merely because the construction scope is finished or the marketing program has begun.
Conversion conditions must be explicit
Determine whether the loan includes a contractual permanent phase, requires a separate new loan, or has another exit. Identify completion, occupancy, income, coverage, documentation, and other conditions in the actual structure.
A construction-to-permanent label does not establish that every borrower receives long-term debt at a predetermined amount. Read the conversion mechanism, pricing, required paydown, and timing. Ask what happens if conditions are not met before maturity.
The SEC-filed Dean Owner loan agreement illustrates how advances, reserves, covenants, and additional obligations can coexist. Its terms are not a template for this project, but the structure reinforces the need to reconcile the whole agreement. SEC-filed loan agreement
Size the permanent loan independently
Assume the completed project supports $900,000 annual NOI and an illustrative 7.5% valuation cap rate. Indicated value is $12 million. At 65% LTV, the value-based ceiling is $7.8 million before other constraints.
If construction principal is $6 million and refinance costs and reserves total $200,000, that ceiling appears sufficient. But accepted cash flow, debt service, debt yield, product eligibility, and cash-out restrictions can still reduce proceeds. Do not label the difference immediately distributable.
Now stress NOI to $650,000 and the valuation cap rate to 8.5%. Value becomes approximately $7,647,059, and 65% LTV supports approximately $4,970,588. Against $6.2 million payoff and refinance uses, the value-based gap is approximately $1,229,412 before further constraints.
Plan for a delayed or failed takeout
Model extension conditions, fees, additional interest, required paydowns, rate protection, and continued operations. Identify the milestone extra time is expected to achieve. Delay alone does not cure an uncompetitive building or unsupported rent.
Compare a sale or additional-equity alternative with appropriate costs and timing. A finished project can still require a different capital structure. An investor who cannot fund the downside should reduce exposure before closing rather than assume future rescue capital.
Report the initial maturity and conditional extension dates separately. Assign responsibility for notices and tests. A long construction narrative should not conceal a short contractual clock.
Chicago execution and investor reporting
Connect the loan to actual site conditions, environmental findings, utility capacity, access, tenant use, approvals, and contractor scope. Each can affect schedule, cost, and financeability. Avoid unsupported universal local allowances.
Monthly reporting should show physical progress, cost-to-complete, reserve cash, undrawn availability, equity remaining, leasing, interest, and takeout readiness. Preserve the original budget and explain changes. Owners need to understand both what has been built and what remains funded.
The investment is ready when scope, capital, timing, obligations, and exit agree. A construction commitment is one component of that funded route from acquisition to durable operations, rather than proof that completion and permanent financing will follow automatically.
Control changes before authorizing them
Require each material change to show scope, price, schedule, funding source, contingency effect, interest effect, and any lender consent. A change that appears affordable in contractor dollars can still extend carrying costs or delay tenant rent. Approve the combined investment consequence rather than the construction invoice alone.
Keep a distinction between work committed, work completed, amounts certified, amounts paid, and retainage. Those measures can differ legitimately, but the differences must reconcile. A project reported seventy percent complete is not necessarily seventy percent paid or funded.
Before the last draw, reconcile all remaining invoices, retainage, inspections, documentation, tenant obligations, and operating support. Final physical completion should leave a clear account of who still owes what and which money remains available to fund it.
A conversion projection also needs a failure path: identify the amount and timing of equity required if the completed building misses the stipulated income test.
