Conventional: A "traditional" mortgage, not directly insured by the Federal Government. Most conventional loans under $275,000 are administered through Fannie Mae or Freddie Mac (private corporations but regulated by the government). Those loans over that amount are designated "jumbo loans" and are funded by the private investment market.

FHA: Insured by (but not funded by) the Federal Housing Administration (FHA) a division of the U.S. Department of Housing and Urban Development (HUD), and designed for, in general, low- and middle-income borrowers and many first-time buyers. There are, however, limits (which vary from county to county) to the maximum loan amount. On January 1, 2000 HUD began insuring home mortgage loans of up to $121,296 in communities where housing costs are relatively low, and loans ranging up to $219,849 in communities where housing costs are relatively high. FHA loans have somewhat more relaxed qualifying standards and ratios than conventional loans and have the availability of both 15 and 30 year fixed as well as 1 year adjustable mortgages.

VA: For those qualified by military service, the Veterans Administration (VA) insures (but does not fund) 15 and 30 year fixed as well as 1 year adjustable mortgages with lower down payment requirements (as low as 0 down) and somewhat more lenient qualifying ratios.

No-Document ("No-doc) Loans: No-doc mortgages are generally a wise choice for self-employed people, those who do not wish to verify their income, and those with a brief or blemished credit history, or no credit. The benefits of a no-doc mortgage include a shorter application process since you are not required to provide income, employment or asset documentation, as well as a streamlined approval process because there is little subsequent verification. However, no doc mortgages generally will be at slightly higher interest rates and are offered by fewer lenders.
