Which of the following is NOT a common type of mortgage?

The choice of "No Doc" is accurately identified as not a common type of mortgage compared to the others listed.

VA (Veterans Affairs) loans are designed specifically for eligible veterans, active-duty service members, and certain members of the National Guard and Reserves, offering benefits like no down payment and no private mortgage insurance. FHA (Federal Housing Administration) loans aim to assist low to moderate-income borrowers by providing easier access to home financing with lower credit score requirements and lower down payments. Conventional loans refer to mortgages that are not insured or guaranteed by the federal government and generally require higher credit scores and down payments compared to VA and FHA loans.

In contrast, "No Doc" mortgages - which involve limited documentation requirements - were more prevalent in the past but are not classified in the same category or as commonly as the first three. The lending landscape has shifted towards stricter documentation standards to ensure borrowers can meet their obligations, making "No Doc" loans less common and mainly used in specific scenarios or offered by select lenders. Thus, it stands out as the option that doesn’t align with the more standard mortgage types widely available today.
