Warehouse Lending

Warehouse Lending

Warehouse lending is a short-term credit facility that a bank or institutional lender provides to a mortgage company to fund individual mortgage loans from origination until the loans are sold to the secondary market, typically to Fannie Mae, Freddie Mac, or private investors. The mortgage company draws on the warehouse line to close each loan, holds the loan in inventory for an average of 15 to 30 days, and repays the draw once the loan sells. The warehouse lender holds the mortgage note as collateral during that holding period.

Think of a warehouse line as a revolving credit card for a mortgage company: it funds loans on the way out and gets paid back as those loans sell forward.

How the Funding Cycle Works

The mechanics follow a predictable sequence on every loan. The mortgage company originates a loan and submits a funding request to the warehouse lender on the day of closing. The warehouse lender wires the closing funds directly to the title company or escrow agent. The mortgage note and deed of trust are delivered to the warehouse lender as collateral. Once the loan package is complete, the mortgage company delivers it to its buyer, typically a large bank or government-sponsored enterprise. The buyer purchases the loan, wires payment back to the warehouse lender to retire the specific draw, and the warehouse lender releases its collateral interest.

The cycle repeats continuously. A healthy mortgage company typically turns its warehouse line three to five times per month, meaning each dollar of credit line capacity funds three to five loans per month.

Key Terms in a Warehouse Agreement

  • Maximum facility amount: The total credit commitment the warehouse lender makes available, often ranging from $10 million for small lenders to several billion for large nonbank mortgage originators
  • Advance rate: The percentage of each loan's value the warehouse lender will fund, typically 98% to 100% of the loan's par value
  • Dwell time: How long a loan can sit in the warehouse before the lender calls the draw due. Most agreements allow 30 to 90 days, after which a penalty rate applies or the lender can demand immediate repayment
  • Gestation rate: The interest rate charged on each funded loan during the holding period, typically a spread over SOFR or the prime rate
  • Haircut: A reduction in advance rate applied to loans with elevated credit risk, including government loans with defects or loans with extended dwell times

Who the Warehouse Lenders Are

Warehouse lending is dominated by a relatively small group of banks and institutional lenders, including Texas Capital Bank, Flagstar Bank, Merchants Financial Group, and several large national banks that serve nonbank mortgage originators. The business requires significant capital commitment and specialized collateral management technology, which limits the number of active participants.

The warehouse lending market contracted sharply during 2022 and 2023 as rising interest rates caused mortgage origination volume to collapse. Several banks exited the business or reduced their commitments, tightening available funding for independent mortgage companies during exactly the period when those companies most needed liquidity support.

Risk Considerations for Warehouse Lenders

Warehouse lenders face several distinct risks that traditional commercial lenders do not. Collateral risk arises if a loan fails to sell because it does not meet the buyer's guidelines, leaving the warehouse lender holding a loan it must sell at market. Fraud risk is significant: a mortgage company that submits duplicate funding requests for the same loan, sometimes called double pledging, can draw cash from two warehouse lenders against a single piece of collateral. Warehouse lenders combat fraud through custodial document tracking, wet ink note delivery requirements, and participation in industry registries like the Mortgage Electronic Registration Systems.
