A Zestimate Is Not an Appraisal! This is where things get ugly. A lot of homeowners, and I suppose some in the industry, seem to get tripped up into thinking a Zestimate is an appraisal. Zillow explains right on its informational page that a Zestimate is not an appraisal, and cannot be used in place of an appraisal.
Lactorrhea, the occasional production of milk by the glands, can occur in any mammal, but in most mammals lactation, the production of enough milk for nursing, occurs only in phenotypic females who have gestated in recent months or years. It is directed by hormonal guidance from sex steroids.
It stimulates the mammary glands to produce milk (lactation): increased serum concentrations of prolactin during pregnancy cause enlargement of the mammary glands and prepare for milk production, which normally starts when the levels of progesterone fall by the end of pregnancy and a suckling stimulus is present.
