Commercial Mortgage Warehouse Lending: How It Works & Who It’s For

Key Takeaways

• Warehouse lending bridges the gap between origination and the secondary market. It gives mortgage originators the short-term capital they need to fund commercial real estate loans while they arrange longer-term financing or prepare to sell loans to investors.
• Speed and liquidity are the core value. Rather than waiting weeks or months for permanent financing, originators can close deals quickly, and keep their pipeline moving.
• Customers Bank is a nationally recognized warehouse lender. We offer credit facilities ranging from $5 million to $300 million, with experienced teams who understand the nuances of mortgage origination at scale.
• It’s available to a wide range of originators. From large mortgage companies to smaller regional lenders, commercial mortgage warehouse lending is accessible to originators who meet eligibility criteria — not just the biggest players in the market.
• Commercial real estate moves quickly. Whether an originator is closing on an office building, a multifamily complex or an industrial property, the ability to fund loans efficiently — without getting stuck waiting for long-term capital to materialize — is often what separates a successful deal from a missed one.

That’s the problem commercial mortgage warehouse lending solves. It’s a financing mechanism built specifically for mortgage originators, giving them a reliable, short-term source of capital to fund deals as they close.

Here’s how it works and what to know before exploring it as an option.

What Is Commercial Mortgage Warehouse Lending?

Commercial mortgage warehouse lending is a form of short-term financing provided to mortgage originators: banks, mortgage companies and other financial institutions that originate commercial real estate loans. Rather than using their own capital to fund each loan at closing, originators draw on a warehouse line of credit, which they then repay once the loans are sold to investors on the secondary market.

Think of it as a revolving bridge between origination and sale. The warehouse lender provides the capital, the originator funds the loan, and when the loan is sold or securitized, the line is repaid and becomes available again for the next deal.

Customers Bank is a nationally recognized warehouse lender offering credit facilities from $5 million to $300 million. Our team has deep experience working with originators across deal types and property classes, and we’re structured to move at the pace the business requires.

How the Process Works

The mechanics of commercial mortgage warehouse lending follow a fairly consistent pattern:

• Origination. A mortgage originator (a bank, mortgage company or other lending institution) identifies and underwrites a commercial real estate loan.
• Warehouse draw. Rather than using its own balance sheet capital to fund the loan at closing, the originator draws on its warehouse line of credit. The warehouse lender provides the short-term funds.
• Secondary market sale or securitization. Once the loan is funded, the originator works to sell it to an investor on the secondary market, or packages it with other loans into a mortgage-backed security. This is how the warehouse line gets repaid.
• Repayment and recycling. As loans are sold, proceeds flow back to repay the warehouse line, freeing up capacity for the originator to fund the next deal. The cycle repeats.

Why Originators Use Warehouse Lending

• Speed to close. Warehouse lines give originators the ability to fund loans quickly, without waiting for permanent financing to be arranged or for a secondary market buyer to be identified in advance. In competitive commercial real estate markets, that speed matters.
• Capital efficiency. Rather than tying up their own balance sheet capital in funded loans, originators can use a warehouse line to fund deals and recycle that capital faster. This supports volume growth without a proportional increase in equity.
• Risk distribution. By selling loans into the secondary market or packaging them into securities, originators move risk off their books, reducing exposure to any individual loan’s performance.
• Business growth. Access to a reliable warehouse line allows originators to expand their pipeline and take on more deals than their own capital base would otherwise support.

Common Questions

What types of properties are eligible?

Commercial mortgage warehouse lending can support a broad range of property types including office buildings, retail spaces, industrial and logistics properties, multifamily residential complexes and more. Eligibility is determined based on the loan characteristics and the originator’s track record and creditworthiness.

What do lenders look at before extending a warehouse line?

Lenders typically evaluate the originator’s experience and performance history, the quality and market value of the underlying collateral and the originator’s operational infrastructure for managing loan pipelines. The strength of the originator’s secondary market relationships also factors in.

Is warehouse lending available to smaller originators?

Yes. Commercial mortgage warehouse lending is not exclusive to large mortgage companies. Smaller and regional originators can access warehouse lines, provided they meet the lender’s eligibility criteria. Customers Bank works with originators across the size spectrum.
