Warehouse Lending

Warehouse Lending is a specialized form of credit offered by banks and large non-bank lenders (Warehouse Lenders) to companies involved in the mortgage banking industry. These lines are used to fund mortgage loans that borrowers use to purchase property.  The mortgage loan is then sold into the secondary market, either directly or through a securitization and the draw on the line is repaid. Dwell time, consisting of the time the warehouse lender holds the loan prior to it being sold to the investor (secondary market) is usually 2 to 15 days, but may be longer. Warehouse lenders advance a percentage against the mortgage loan, typically 96% - 99% (if the warehouse provider is also the investor the advance is 100% with no discount), forcing the mortgage banker to provide some of its own capital.   If the dwell time is too long, the warehouse lender may force the mortgage banker to pay back the advance with their own funds.

There are two forms of funding in warehouse lending, wet funding and dry funding. Under wet funding the mortgage loan provider get its funds at the loan closing, but prior to the documentation being submitted to the warehouse lender. Under dry funding, the mortgage loan provider receives and reviews the mortgage loan documents prior to releasing the funds. 

Wet Funding has higher fraud risk for the warehouse lender.  Accordingly, the warehouse lenders needs to complete due diligence on the mortgage banker and on its systems and processes.  Technology has reduced processing time and cost, and improved accuracy.
