He suggested that Congress could consider allowing the companies, known as "government sponsored enterprises," buy mortgages of as much as $1 million from lenders
Grrrr, the Government has no business guarenteeing loans for $1,000,000. Loans of that value do not promote ownership for the general public.
In fact, IMHO, the GSE limits should be a simple function of 5X median income for a MSA. That promotes healthy ownership of the masses.
