What jumbo loans are and how they differ from conforming financing.
Jumbo loans are non-conforming mortgages that exceed the Federal Housing Finance Agency (FHFA) conforming loan limit. In San Diego County, the 2026 conforming limit is $1,104,000. Any loan amount above this threshold requires jumbo financing.
Key distinction: Jumbo loans are not backed by Fannie Mae or Freddie Mac, which means lenders assume more risk. This typically results in stricter qualification requirements (higher credit scores, lower debt-to-income ratios, larger down payments) and slightly higher interest rates compared to conforming loans. However, San Diego County's competitive jumbo market often offers rates within 0.25-0.50% of conforming rates.

The qualification requirements and underwriting process for non-conforming financing.
Jumbo loans require stronger financial profiles than conforming loans due to increased lender risk. Lenders evaluate credit score, income stability, debt-to-income ratio, liquid reserves, and down payment. San Diego County jumbo borrowers typically need 700+ credit scores and 10-20% down payment.
20% down = $300,000. Loan amount: $1,200,000 (jumbo). Monthly payment: ~$8,000 (principal + interest at 7% rate).
20% down = $500,000. Loan amount: $2,000,000 (jumbo). Monthly payment: ~$13,300 (principal + interest at 7% rate).
25% down = $750,000. Loan amount: $2,250,000 (jumbo). Monthly payment: ~$15,000 (principal + interest at 7% rate).
Credit score: 700+ minimum, 720+ preferred for best rates. 740+ may qualify for 10% down options.
Debt-to-income ratio: Typically 43% maximum, including the new mortgage payment.
Liquid reserves: 6-12 months of mortgage payments (PITI) after closing. Loans above $2,000,000 require 12-24 months reserves.

A first-time homebuyer in Chula Vista qualifies for a 3% down payment conventional loan through the HomeReady program. They purchase a $650,000 property with $19,500 down (3%) and finance $630,500. With a 680 credit score, they pay PMI monthly. After several years of payments and property appreciation, they reach 20% equity and request PMI removal, reducing their monthly payment by approximately $250.
A San Diego County homeowner sells their current property and uses $150,000 in proceeds as a down payment on a $900,000 home in Carlsbad. With 16.7% down, they finance $750,000 and pay PMI. Their 750 credit score qualifies them for competitive rates. Within two years, property appreciation brings them to 20% equity, and they request PMI removal.
A buyer purchasing a $1,050,000 property in La Jolla requires financing above the baseline conforming limit ($832,750) but below the San Diego County high-balance limit ($1,104,000). They put 20% down ($210,000) and finance $840,000 with a high-balance conventional loan. They avoid PMI and secure competitive terms without entering jumbo loan territory.
