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.
The impact of these factors on mammary function is evident from the known effects of frequency of milk removal on milk yield, the effects of galactopoietic hormones on milk secretion, and the effects of milk stasis-induced mammary involution on mammary function.
