Credit score is one of the most misunderstood factors in the home-buying process. Many buyers disqualify themselves before speaking to a lender because they assume their score is too low. The reality: there are loan programs for scores from 500 all the way to 780+, and the right program makes a significant difference in your monthly payment.
Minimum Credit Scores by Loan Type in California
| Loan Type | Minimum Score | Optimal Score | Notes |
|---|---|---|---|
| FHA | 500 (10% down) / 580 (3.5% down) | 640+ | Most lenders add 20-pt overlay |
| Conventional | 620 | 740+ | Best rates above 740 |
| VA | No VA minimum | 620+ (lender overlay) | Lenders typically require 580–620 |
| USDA | 640 | 680+ | Rural areas only |
| ITIN / Portfolio | Non-traditional credit | N/A | Rent & utility history |
| Jumbo | 700+ | 720+ | Loan > county conforming limit |
How Credit Score Affects Your Mortgage Rate
The difference between a 620 and a 740 score can cost or save you hundreds of dollars per month. On a $420,000 conventional loan in California, a borrower with a 680 score might pay 7.25% vs. 6.625% for a 740 borrower — a gap of roughly $170/month, or $61,200 over 30 years. Getting your score from 680 to 740 before buying is often worth a 3–6 month delay.
5 Things That Damage Your Score Before Closing
- Opening new credit cards or applying for new loans after pre-approval
- Making large purchases on existing credit (car, furniture, appliances)
- Paying late on any account — even once before closing
- Closing old credit cards (reduces available credit, raises utilization ratio)
- Co-signing for someone else's loan or lease
How to Improve Your Score 30–50 Points in 90 Days
- Pay down credit card balances to below 30% of the limit (utilization = 30% of your score)
- Dispute any errors on your credit report (pull free reports at annualcreditreport.com)
- Become an authorized user on a family member's old account with clean payment history
- Ask creditors to remove a single late payment as a goodwill adjustment
- Do not close any accounts — length of history matters
- Make all minimum payments on time, every time, during the improvement period
No Credit Score? You Still Have Options
FHA allows manual underwriting for borrowers with no credit score (no tradelines at all), provided you have 12 months of on-time rent payments and at least two other payment references (utilities, phone, insurance). This path takes longer but is legitimate. ITIN buyers without U.S. credit history often qualify this way. We work with underwriters who do manual files regularly.
Frequently Asked Questions
What is the minimum credit score to buy a house in California?+
500 with an FHA loan at 10% down, 580 with FHA at 3.5% down, 620 for conventional loans. VA loans have no government-set minimum, but most lenders require 580–620. ITIN/portfolio loans use alternative credit — no traditional score required.
How long does it take to improve my credit score?+
Paying down balances and disputing errors can show results in 30–60 days. Building a 12-month payment history takes — you guessed it — 12 months. Most buyers can move from 600 to 650+ in 60–90 days with focused effort on utilization and errors.
Does getting pre-approved hurt my credit score?+
A single mortgage inquiry typically reduces your score by 5 points or less and recovers within a few months. Multiple mortgage inquiries within a 45-day window count as a single inquiry under FICO's rate-shopping rules — so getting quotes from 3 lenders in a month does not triple the impact.
Can I buy a house in California with a 580 credit score?+
Yes, with an FHA loan at 3.5% down. Some lenders require 620+, so it may take a few calls to find one who underwrites at 580. We work with lenders who approve at 580 — call us and we'll connect you with the right one.
