Mortgage Calculator for Southern California Home Buyers
California home prices are among the highest in the nation. Before you start shopping, you need to know what monthly payment you can comfortably carry — and that number includes more than just principal and interest.
This mortgage calculator is built for Southern California buyers. It factors in California property taxes (typically 1.1–1.25% of assessed value under Prop 13), homeowners insurance, HOA dues common in LA and OC condos, and PMI for buyers putting less than 20% down.

Frequently Asked Questions
What is the average mortgage payment in Southern California?
On a $750,000 home with 20% down ($600,000 loan) at 6.5% interest over 30 years, your principal and interest payment would be approximately $3,792/month. Add property taxes (~1.1% in CA, or ~$688/month) and insurance (~$150/month) and you are looking at roughly $4,600/month total.
How much do I need to earn to buy a home in Los Angeles?
Lenders typically require your housing costs to be no more than 28–31% of your gross monthly income. For a $4,600/month payment, you would need approximately $177,000–$197,000 in annual household income. Dual-income households and strong credit scores can improve your options.
What are property taxes in Southern California?
California property taxes are capped at 1% of assessed value under Proposition 13, plus local assessments that typically bring the effective rate to 1.1–1.25%. On a $750,000 home, expect $8,250–$9,375 per year ($688–$781/month) in property taxes.
Do I need PMI if I put less than 20% down in California?
Yes. Private mortgage insurance (PMI) is required on conventional loans when you put less than 20% down. PMI typically costs 0.5–1.5% of the loan amount annually. On a $600,000 loan, that is $250–$750/month until you reach 20% equity.
