How Modular Construction Funding Has Stacked in the Past: Lessons from a Changing Industry

In recent years, modular construction has emerged as a transformative force in the building industry — promising faster delivery, higher quality control, and reduced waste. Yet, despite its clear advantages, funding modular projects has often been a challenge. Understanding how modular construction funding has “stacked” in the past — that is, how financing has traditionally been layered and structured — helps explain both the progress and the pitfalls of this fast-evolving sector.

1. The Traditional Capital Stack in Construction

Before modular came along, the capital stack for a conventional real estate project was relatively straightforward:

• Senior debt from banks or institutional lenders,

• Mezzanine debt or preferred equity to fill the gap,

• And common equity from the developer or project sponsors.

The model was designed for traditional, on-site construction where payments were made progressively as the building rose out of the ground. That system aligned with how lenders viewed risk — they could see the work as it happened and release funds accordingly.

2. Why Modular Changed the Funding Equation

Modular construction flips that sequence. Instead of building most of the structure on-site, large portions of the project are fabricated off-site in a factory, then transported and assembled on location. This shift created a timing mismatch that many traditional lenders weren’t ready for.

Here’s the problem:

• Upfront capital requirements are higher. Factories need payment early to purchase materials and start production.

• Collateral looks different. Modules in a warehouse don’t always count as “secured property” from a bank’s perspective.

• Draw schedules don’t align. Traditional lending relies on inspections of on-site progress, but much of the value in modular is created off-site, beyond the lender’s usual comfort zone.

The result? Developers often found themselves front-loading equity or seeking alternative financing to cover the factory phase.

3. How Funding Has Been Stacked Historically

In the past decade, we’ve seen modular projects financed through a mix of creative capital stacks:

• Developer Equity & Early-Stage Capital: Developers often contributed more equity upfront to kick-start manufacturing, absorbing risk until construction loans could be drawn.

• Bridge Financing: Short-term, high-interest loans or private funds were used to bridge the gap between factory production and traditional construction draws.

• Factory Financing & Vendor Credit: Some modular manufacturers offered their own financing terms or payment deferrals, effectively acting as lenders to the project.

• Public and Impact Investment: Especially for affordable housing and sustainability-driven projects, public agencies and impact investors have stepped in to de-risk the capital stack with grants, low-interest loans, or guarantees.

• Joint Ventures: Developers and modular builders have partnered to align incentives and share capital risk, creating vertically integrated models.

4. What the Industry Learned

The early years of modular funding taught several key lessons:

• Timing is everything. Synchronizing factory payments with lender draw schedules is critical.

• Education matters. Traditional lenders need to understand modular’s workflow and risk profile.

• Collaboration reduces friction. The most successful projects involved close coordination between developers, lenders, manufacturers, and investors.

• Data builds trust. Proven track records and performance metrics from modular projects are helping lenders become more comfortable with the model.

5. The Road Ahead

While funding modular projects used to require patchwork solutions, the industry is maturing. Today, more construction lenders and investors are adapting their underwriting standards to fit modular timelines. Some are even developing modular-specific loan products and insurance-backed guarantees to streamline funding.

In the future, expect to see standardized modular capital stacks that integrate:

• Early manufacturing loans,

• Off-site progress verification,

• And hybrid debt-equity instruments designed for modular’s unique flow.

Final Thoughts

Modular construction funding has evolved from a fragmented, high-equity model into a more sophisticated financial ecosystem. Understanding how the capital stack was built in the past helps us design better structures for the future — ones that unlock modular’s full potential for efficiency, scalability, and affordability.
