Why Development Financing Is Different from a Standard Mortgage

Buying an existing home involves a relatively straightforward transaction: a lender appraises a completed property and extends a mortgage based on its current value. Development financing operates under an entirely different logic. At the start of a project, there is no finished asset to appraise — only a site, a set of plans, and a projected future value.

This uncertainty means lenders price development loans differently, impose stricter conditions, and release funds incrementally rather than upfront. Developers must demonstrate not only that the finished project will be worth more than it costs to build, but also that they have the team, track record, and equity to execute the plan. For a broader picture of how a project moves from concept to completion, see our overview of the property development process.

Development Finance Is Not Retail Lending

Construction and development loans are commercial products, not consumer mortgage products. They are typically originated by commercial banks, credit unions with commercial lending arms, or private lenders — not through the residential mortgage channels most buyers are familiar with. Underwriting standards, documentation requirements, and loan terms differ substantially from those of a standard home loan.

The Capital Stack: Understanding the Layers of Funding

The capital stack is the term used to describe how a development project is funded in layers, each with different risk and repayment priority. Understanding it is essential to understanding development finance.

  • Senior debt sits at the top. This is typically a construction loan from a bank or institutional lender. It is the first to be repaid and is secured by the property itself, which is why it commands the lowest interest rate of any layer.
  • Mezzanine debt occupies the middle. It bridges the gap between the senior loan and the developer's equity. Because it is subordinate to senior debt in repayment, it carries meaningfully higher interest rates. Mezzanine lenders sometimes negotiate equity participation rights.
  • Preferred equity is occasionally inserted between mezzanine debt and common equity. Preferred equity investors receive returns before common equity holders but after all debt is repaid.
  • Common equity sits at the bottom. The developer and any equity partners absorb the first losses if something goes wrong — but also capture the largest upside if the project succeeds.

60–70%

Typical senior debt share of total project cost

Most construction lenders advance between 60% and 70% of total project costs as senior debt, requiring developers to source the remainder through equity or subordinate financing.

12–36 months

Typical construction loan term

Construction loans are short-term instruments, generally requiring repayment or refinancing within one to three years of origination once the project reaches completion or stabilization.

20–35%

Equity contribution typically required by lenders

Commercial construction lenders generally require developers to contribute equity covering 20–35% of total project costs before advancing senior debt funds.

The ratio of debt to equity in a project's capital stack is closely scrutinized by lenders. A project that is too heavily leveraged raises the risk of default if costs overrun or sale prices disappoint — a dynamic explored in our guide to development cost overruns.

How Construction Loans Work in Practice

The primary debt instrument in development finance is the construction loan. Unlike a term loan, it is a draw-based facility: the developer does not receive the full amount at closing. Instead, funds are drawn down in stages as the project achieves defined construction milestones — site preparation, foundation, framing, mechanical systems, and so on. A lender's inspector or title company typically verifies each milestone before releasing the next draw.

Construction loans are short-term, usually carrying terms of 12 to 36 months. Interest accrues on drawn balances and is commonly rolled into the loan rather than paid monthly, preserving the developer's cash during the build. At completion, the loan must be repaid — either through a permanent refinance on the stabilized asset or through sales proceeds.

Track Draw Schedules Carefully

A mismatch between your construction draw schedule and your contractor's payment requirements is one of the most common cash-flow problems in development projects. Work with your general contractor to align milestone completion dates with lender draw timelines before breaking ground. Building in a contingency buffer — typically 5–10% of hard costs — can help absorb timing gaps without derailing the project.

Loan-to-cost (LTC) and loan-to-value (LTV) ratios govern how much a lender will advance. LTC compares the loan amount to total project costs; LTV compares it to the projected finished value. Both measures help lenders set guardrails against overleveraging.

Equity Sources and Joint Venture Structures

Equity — the developer's own skin in the game — can come from several sources. Smaller developers often contribute personal capital or retained earnings. Larger or more complex projects frequently bring in joint venture partners: institutional investors, family offices, or private equity funds that contribute equity in exchange for a negotiated share of profits.

These arrangements are governed by a joint venture or operating agreement that specifies how costs, decision-making authority, and returns are allocated. A common structure is the "promote" or "carried interest," where the developer receives a disproportionately large share of profits above a defined return threshold as compensation for managing the project. The exact terms vary significantly by deal.

Understanding who plays what financial role in a development project connects directly to the broader team structure — covered in our breakdown of development project roles. Financing structures also differ substantially between property types; residential and commercial development follow meaningfully different lending conventions.
