There are some lenders that arrange FHA financing and also arrange for mortgages that will be sold to Fannie Mae, and they might also arrange for a loan that will be sold to a private investor or a small bank, etc, etc. Just because they are capable of arranging any type of mortgage situation from the borrower, it doesn't mean that all guidelines for all clients would apply in a single transaction. If it is to be an insured FHA loan, then all the guidelines in 4150.2, FAQs, National HOC Reference Guide and now the policy regarding missing tags would apply. Completely separate and two different situations. So if it is an FHA loan then all HUD requirements apply. It it is a Fannie Mae type loan, then all Fannie Mae guidelines apply. Same for if it was a VA loan or a loan that would be sold to Freddie Mac. Each type of lender has their own little box to fit in--and trying to combine all guidelines in one package just doesn't work or apply. The 1004C is for loans to be sold to Fannie Mae only--although private investors or portfolio lenders might want a check list (grrrrr), and if they do then I will provide the 1004C, but it is not automatically required like Fannie Mae.
FHA loan == HUD requirements only apply
Fannie Mae loan == Fannie Mae guidelines only apply, the 1004C is for loans that Fannie Mae will purchase, where they are going to be chancing their money
Other types of loans == whatever the client guidelines say (as long as it is honest and ethical).
