Homeowners' Defense Act of 2007

Homeowners' Defense Act of 2007 - Establishes the National Catastrophe Risk Consortium as a nonprofit, nonfederal entity to: (1) maintain an inventory of catastrophe risk obligations held by state reinsurance funds, and state residual insurance market entities; (2) issue, on a conduit basis, securities and other financial instruments linked to catastrophe risks insured or reinsured through Consortium members; and (3) act as a centralized repository of state risk information accessible by certain private-market participants.

Instructs the Secretary of the Treasury to implement a national homeowners' insurance stabilization program to make liquidity loans and catastrophic loans to qualified reinsurance programs to: (1) ensure their solvency; (2) improve the availability and affordability of homeowners' insurance; (3) provide incentive for risk transfer to the private capital and reinsurance markets; and (4) spread the risk of catastrophic financial loss resulting from natural disasters and catastrophic events.

Authorizes the Secretary to establish and collect, from qualified and precertified reinsurance programs, a reasonable fee to offset expenses of the program.

Instructs the Secretary to require full repayment of all loans made under this Act.
