Construction Pro Forma: Draws, Interest Reserve, and Loan Balance

Follow acquisition costs, construction spending, loan draws, accrued interest, and sale proceeds from project start through condominium closings.

Created by Desen Lin · California State University, Fullerton

One project, two linked schedules

The project pro forma determines when funds are needed. The construction-loan account determines how those needs are financed.

Project-level pro forma

When do project costs and sale proceeds occur?

Acquisition and construction create negative unlevered cash flows. Presales and condominium closings determine when positive cash flows become available.

Construction-loan account

How much of the facility remains for project costs?

Cash advances and accrued interest share one commitment. Interest can increase the loan account even when no new construction work is funded.

Cash advances outstanding + accrued interest = total loan balance ≤ construction-loan facility

Interactive condominium development model

The default assumptions reproduce the structure of Figures PIII.13 and PIII.14. Move one assumption and every linked schedule updates.

Construction spending and the S-curve

Per-period spending follows a concentrated construction schedule. Cumulative spending converts that distribution into an S-shaped path.

The gray baseline remains fixed. Duration, peak timing, spread, budget, and cost overruns change the navy active-case series.

A steeper middle section means that a larger share of the budget is spent over a shorter interval. Sales-only assumptions do not change either construction curve.

Construction-loan account

The total loan balance combines cash advances and accrued interest. The second panel isolates the accrued-interest balance that compounds inside the facility.

Quarterly project and financing schedule

The table joins the unlevered project cash flows from Figure PIII.13 with the financing schedule from Figure PIII.14.

Period Project costs Net sales cash Unlevered cash flow Cash advance Interest expense Loan repayment Ending loan balance Equity contribution Cash to equity

Project costs are shown as positive uses in this schedule. Cash-flow rows in a conventional pro forma would display those uses as negative amounts.

What students should notice

The timing of otherwise identical project costs changes financing needs and the developer’s equity outcome.

Interest uses loan capacity

When the facility includes an interest reserve, every dollar of accrued interest leaves one less dollar available for acquisition or construction costs.

Timing changes financing cost

Earlier spending creates a larger balance sooner. A longer period before closing allows interest to accrue for more quarters.

Sales follow a repayment waterfall

Net closing proceeds first cover interest and the outstanding loan account. Equity receives only the remaining cash.

Course-case source: FIN 355 prerequisite workbook, Figures PIII.13 and PIII.14. The construction-spending visualization extends the S-curve concept in Chapter 10, Figure 10.3. This tool makes the inclusive-facility interpretation explicit: interest is estimated quarterly using the average total loan balance and compounds while it remains in the account. Presale deposits remain in escrow unless the release option is selected.
