JSMedia – A new plan to offload risk from mortgage insurers may lead the federal government to offer a government guarantee in exchange for a share of the losses on a portion of loan defaults. The concept is called risk-sharing, and it requires lenders to absorb a portion of mortgage insurance losses. But this change could also disrupt the way lenders fund multifamily loans, especially securitized financing programs. The proposal would require lenders to take one-third of the risk of early loan defaults on mortgages.
