How San Diego affordability actually works in 2026
With the 30-year fixed near 6.71% and a San Diego County detached median around $1.03 million, affordability here is tighter than most of the country. But "can I afford it?" isn't one number — it's the interaction of your income, your existing debts, your down payment, and the two costs buyers routinely underestimate: property taxes and insurance.
The 28/36 guideline
Most lenders want your total housing payment under about 28% of gross monthly income, and all your debt payments combined under about 36%. This calculator uses the more conservative of the two so your estimate is realistic, not optimistic.
Don't forget taxes and insurance
San Diego County's effective property-tax rate runs roughly 1.05–1.25% of value per year, and California home-insurance premiums have climbed sharply — State Farm won an emergency 17% homeowner rate hike and more zip codes now lean on the state FAIR Plan. Price insurance before you fall for a house; in many neighborhoods it moves the math as much as the mortgage rate.
Rate moves change your budget weekly
Because mortgage rates track the 10-year Treasury, your buying power shifts as markets move. I keep today's rate live and updated daily on the Market Journal IQ homepage — check it before you lock a price range in your head.
