A Jumbo loan is any loan amount that exceeds the high-balance loan limit set per county. High-balance loan limits for your city in California can be found here: California City High-Balance Loan Limits with a current absolute maximum of $729,750.00.

If you exceed this amount for your city/county, then you must get a Jumbo loan.  Jumbos have been fairly hard to come by the past couple of years because many lenders found them too high-risk and did not offer them. For the lenders that did offer them, they usually came with a high rate and expensive fees.

The good news though is that there has been a rally in competitive interest rates for Jumbo loans, in particular with Adjustable Rate Mortgages (ARMs). Today’s interest rates are as follows.  (Please note that the rate and Loan-to-Value requirement is very sensitive to the location of your property.  The below rates assume FICO scores above 720, Loan Amount up to $1,000,000.00, no impound account, no cash-out on equity, single family home, primary residence.  They are all with zero points and no prepayment penalty.  APR is based on a loan amount of $800k).

Loan-to-Value (LTV) ratio of 70.0% and below:

Loan Product Interest Rate APR
5/1 ARM 3.875% 3.916%
7/1 ARM 4.250% 4.292%
10/1 ARM 4.625% 4.668%
30 Year Fixed 5.875% 5.922%

LTV ratio between 70.01% and 80.0%: (allows for lesser equity, but note the interest rates are higher):

Loan Product Interest Rate APR
5/1 ARM 4.250% 4.292%
7/1 ARM 4.750% 4.793%
10/1 ARM 5.250% 5.295%
30 Year Fixed 5.875% 5.922%

These rates are approximate .25% higher in rate than high-balance loan amounts, with the exception of the 30 Year Fixed, which is almost a full percentage point higher.
