What Credit Score Do You Need to Buy a House in California?
There is no single credit score that fits every mortgage. Here is how conventional, FHA and VA requirements differ and why the full loan cost matters.

What credit score do I need to buy a house in California?
It depends on the mortgage and the lender. FHA guidelines allow scores of 580 or higher for financing with as little as 3.5% down, or 500–579 with at least 10% down, subject to other requirements. VA sets no minimum score. Conventional requirements vary; Fannie Mae’s Desktop Underwriter does not require a fixed minimum score. Lenders can set stricter requirements, and a score alone does not guarantee approval.

If you are planning to buy a home in San Diego, Riverside or elsewhere in Southern California, you may wonder whether your credit score is high enough.
You do not have to figure that out alone. The useful starting point is to understand which loans may fit your situation, what each would cost, and what the lender needs to see.
Conventional loan credit requirements
Conventional loans are not insured by FHA or guaranteed by VA. Many buyers have heard that a conventional mortgage always requires a 620 score. That is too broad.
Fannie Mae’s Desktop Underwriter, an automated system lenders use to assess applications, no longer requires a fixed minimum credit score. It still reviews the borrower’s creditworthiness.
Fannie Mae’s manually underwritten fixed-rate loans generally retain a minimum of 620. Other products and lenders have their own requirements. A lender may require a score above an agency’s minimum.
So a score below 620 is a reason to ask about your options. It is not a promise that a conventional loan will be available.
FHA credit and down payment requirements
For borrowers with a credit score, FHA’s standard purchase guidelines provide these starting points:
- 580 or higher: potentially eligible for maximum financing, with as little as 3.5% down.
- 500–579: financing is limited to 90% of the property’s adjusted value, meaning at least 10% down.
The adjusted value generally uses the lower of the purchase price or appraised value, with certain adjustments. A low appraisal can increase the cash you need.
These are FHA program rules. The lender can set a higher minimum score, and you still need to meet income, debt, property and other requirements. Your down payment also does not cover every closing cost.
VA credit requirements
VA does not set a minimum credit score for its home loan benefit. Individual lenders may set one and must review your ability to repay.
Eligible borrowers may be able to buy without a down payment. VA loans do not require monthly mortgage insurance, although a funding fee may apply unless you qualify for an exemption.
If you are eligible, ask to compare VA financing with your other available options.
Credit can affect costs as well as approval
A higher credit score can improve the loan pricing available to you. Your down payment, loan type, loan term and lender also matter.
Mortgage insurance is another cost to compare:
- Conventional: with less than 20% down, private mortgage insurance, or PMI, is usually required. Its cost can vary with your score and down payment.
- FHA: mortgage insurance includes an upfront premium and an annual premium collected monthly. Its premium rates are not based on your credit score.
- VA: there is no monthly mortgage insurance. Include any applicable funding fee when comparing costs.
FHA mortgage-insurance costs are separate from the lender’s interest rate and fees. The same insurance rules do not mean every FHA borrower gets the same rate.
No loan type is automatically the least expensive for everyone. Ask for a comparison that includes the full monthly payment, closing costs and how long you expect to keep the loan.
Buying with a 640 credit score
A 640 score may leave you with options, but it cannot tell us whether you qualify or whether buying now fits your budget.
I would also want to understand your income, current debts, savings, price range and the property you are considering.
Then we can compare the options available now and discuss whether working on your credit first could help. Future rates, prices and credit-score changes are uncertain, so any later scenario is an estimate.
What to do before making changes to your credit
Before closing a card, opening a new account or making a large debt payment to prepare for a mortgage, ask how that change could affect your application and the cash you need for closing.
Keep making required payments on time. A mortgage review is not a reason to delay a payment.
Ask the loan officer which credit scores they are using, what the lender requires and what else you need to qualify.

Frequently asked questions
Do I need a 700 credit score to buy a home?
A 700 score is not a universal mortgage requirement. The loan program, lender and the rest of your application determine eligibility. A stronger score may improve your available pricing.
Does meeting FHA’s minimum score guarantee approval?
No. A lender can require a higher score, and your income, debts, funds and property must also meet its requirements.
Does VA have a minimum credit score?
VA does not set a minimum score. Individual lenders can set one and still need to review your credit and ability to repay.
