During the previous real estate cycle 5%-down, non-FHA loans were available in the early-to-mid 1990’s.
So it depends what you mean by full circle, but I don’t think loose lending is anywhere close to the mid-2000’s level.
Plenty of additional mechanisms for looser have not been put into play yet.
5% down, full-doc with conservative debt ratios is not necessarily bad by itself. Probably just the first step of 10 towards the next debacle. We have a ways to go.
