Interim Construction Financing

Interim construction financing is a short-term loan that funds the cost of building or substantially renovating a commercial property until the project is completed and either stabilized or taken out by permanent financing. These loans typically operate on a draw schedule tied to construction milestones, require inspections and lien waivers, and often carry interest-only payments and an interest reserve. Underwriting focuses on the construction budget, contractor capacity, and projected stabilization metrics, with covenants to manage cost overruns and schedule adherence during the construction period.

Developers and sponsors secure interim construction financing to mobilize construction, buy materials, and pay contractors according to an approved draw schedule. In practice, borrowers submit construction budgets, AIA-style draw requisitions, and inspection reports to trigger disbursements while lenders monitor progress through periodic site visits and documentation. Sponsors must coordinate the interim loan with their exit strategy—whether a permanent mortgage, sale, or refinance—and ensure reserve levels and contingency provisions are appropriate to cover overruns and avoid disruptions that could delay repayment or conversion.

Interim construction financing is vital because it turns project plans into built product; without it, projects cannot move beyond entitlement and pre-development. It allows sponsors to sequence capital efficiently, converting development risk into an asset that can be stabilized and refinanced. Good interim financing terms and disciplined draw administration limit cost and schedule risk, protect lender collateral, and provide transparency to investors. Conversely, weak oversight or under-budgeting during the interim period is a common source of project failures and can threaten the viability of the permanent capital stack.
