Remember that the subject is never part of a prepositional phrase. The subject of a verb will never be part of a prepositional phrase. A prepositional phrase begins with a preposition [in, on, at, between, among, etc.] and ends with a noun, pronoun, or gerund.
Jumbo loan limits in California range from $417,000 to over $600,000. The median value of a home in California is more than double the median values of homes for United States as a whole, even though the median income is only slightly higher.
Any loan amount higher than this is considered a jumbo loan and will not be backed by Fannie Mae or Freddie Mac. The next level, referred to as a super jumbo loan, is for loan amounts over $1 million.
