Ground-Up Construction Loans: Sizing LTC Limits and Contingencies

Ground-up construction loans are short-term, interest-only commercial debt instruments used by real estate developers to fund the land acquisition, horizontal site preparation, and vertical building of new properties. Unlike standard bridge debt used for acquiring existing cash-flowing assets, these facilities fund projects that produce zero revenue during their term, making the underwriting highly dependent on future valuations, stringent budgeting, and the developer's execution track record.

When a sponsor brings a raw dirt or shovel-ready project to Phoenix Capital, the entire conversation begins with the constraints of the capital stack. Private lenders typically constrain ground-up construction loans by two primary metrics: Loan-to-Cost (LTC) and Loan-to-After-Repair-Value (LTARV). A standard private lending term sheet will offer up to 75% or 85% LTC, capped at 65% to 70% LTARV. The lender will fund whichever number is lower. This dual-cap structure protects the lender from over-leveraging a project that is built inefficiently, while ensuring the developer has enough skin in the game if market caps rates expand during the 18 to 24 months it takes to complete the build.

Sponsors must understand exactly what qualifies as "cost" in that LTC calculation. A proper project budget is divided into land basis, hard costs, soft costs, interest reserves, and contingencies. Hard costs cover the tangible materials and labor required to go vertical—lumber, concrete, framing, plumbing, and electrical. Lenders will fund 100% of these hard costs in arrears, meaning the developer completes a phase, an inspector verifies the work, and the lender reimburses the developer. However, the initial capital injection from the sponsor must cover the gap between the total project cost and the loan amount. This sponsor equity is almost always required to be deployed first, typically going toward land acquisition, permitting, and architectural plans.

Soft costs are often the friction point in underwriting ground-up construction loans. These include architectural and engineering fees, legal costs, permits, environmental reports, and holding costs like taxes and insurance. While private lenders will finance certain soft costs, developers cannot expect to borrow against arbitrary developer fees or vague overhead allocations. We require a highly itemized soft cost budget, and we scrutinize these line items to ensure every dollar requested is directly advancing the physical completion and legal compliance of the asset.

Because a ground-up project generates no income, the interest payments must be capitalized into the loan itself. This is known as an interest reserve. If a developer secures a $5 million loan at SOFR plus 500 basis points, the projected interest over an 18-month term must be calculated and set aside from the loan proceeds at closing. The lender draws from this reserve monthly to pay the interest bill. Sponsors often mistakenly view the interest reserve as "lost" money, but it is a critical mechanic that prevents the project from defaulting while the property is still wrapped in scaffolding. The size of the reserve depends on the draw schedule; since interest is only charged on deployed capital, a back-loaded build schedule will burn less interest than a project requiring massive upfront infrastructure expenditures.

Contingencies are another non-negotiable element of the budget. A standard private construction loan requires a hard cost contingency of at least 5% to 10% of the total construction budget. If supply chain disruptions cause lumber prices to spike, or if a site grading issue requires unexpected excavation, this contingency pool keeps the project moving without requiring the sponsor to scramble for an emergency capital call. Lenders will not allow developers to under-capitalize a project just to make the return metrics look better on a spreadsheet. If the contingency is not used by the time the project reaches its final phases, those funds can often be reallocated to premium finishes or simply left undrawn, reducing the final principal balance.

Beyond the math, the execution risk of ground-up development requires specific structural guarantees. Even on non-recourse or limited-recourse loans, lenders demand a strict Completion Guaranty. This is a legally binding commitment from the sponsor that, regardless of cost overruns or budget shortfalls, they will physically finish the building. If the developer runs out of money, the Completion Guaranty obligates them to bring outside capital to finish the job, protecting the lender from taking back a half-finished shell.

Navigating the current macroeconomic environment makes private construction loans increasingly valuable. Regional banks, traditionally the primary source of this capital, have severely restricted their commercial real estate exposure due to regulatory pressures and deposit flight. Bank loans may offer rates in the 7% to 8% range, but they now demand 40% to 50% cash equity and require months of agonizing committee approvals. Private lenders move at the speed of the market, offering reliable execution for developers who have secured their entitlements and are ready to break ground immediately.

Ultimately, successful ground-up development is about managing downside risk. The developer brings the vision, the general contractor brings the execution, and the lender brings the fuel. By understanding how lenders underwrite LTC limits, scrutinize soft costs, and mandate interest reserves, sponsors can structure their capital stacks efficiently. When the numbers align, construction loans provide the exact leverage required to turn raw dirt into stabilized, institutional-grade real estate assets.
