Getting a Home Loan With Bad Credit in California
What it costs, what it takes, and how long before you can refinance out of it.

What Bad Credit Actually Costs
The premium is real and worth quantifying before you decide whether to buy now or wait. Conventional pricing moves in tiers, and the spread between the top and bottom of the range is substantial.
| Credit score | Typical rate impact | Monthly cost on a $700,000 loan |
|---|---|---|
| 760+ | Best available pricing | — |
| 700–739 | +0.25% to +0.375% | +$105 to +$160 |
| 660–699 | +0.50% to +0.75% | +$210 to +$320 |
| 620–659 | +0.875% to +1.25% | +$375 to +$540 |
| 580–619 (FHA) | FHA pricing plus MIP for life of loan | Varies — MIP adds ~0.55%/yr |
Figures are illustrative for a 30-year fixed and move with the market. The point is the shape: the penalty accelerates as the score falls, and the jump below 660 is the steepest.
Buy Now or Wait?
The honest answer depends on two numbers — how fast your score can realistically improve, and what the property market does meanwhile.
If you can gain 40 points in 60 days by paying down revolving balances, waiting is usually worth it, because one pricing tier on a large California loan outweighs two months of appreciation in most markets. If your score needs two years of seasoning after a bankruptcy or foreclosure, waiting has a real cost in a rising market, and buying with a non-QM loan and refinancing later often wins.
The Refinance Exit
A bad-credit mortgage is rarely meant to be permanent. The standard plan is to buy now at a higher rate, then refinance into conventional pricing once two things are true: your score has recovered past 680, and any credit event has aged past its seasoning window.
Budget for the refinance cost when you take the original loan — typically 2% to 3% of the loan amount — and avoid prepayment penalties, which are common on non-QM but usually negotiable at application. Run the numbers with the refinance calculator before committing.
FHA mortgage insurance is not removable
On an FHA loan with less than 10% down, mortgage insurance runs for the life of the loan — unlike conventional PMI, which cancels at 20% equity. That is a strong reason to plan the refinance into conventional rather than treating an FHA loan as permanent. At roughly 0.55% a year on a $700,000 loan, MIP alone is about $320 a month indefinitely.
Documentation Matters More at Low Scores
Files with damaged credit get scrutinised harder. Every large deposit needs a paper trail, every gap in employment needs an explanation, and every derogatory item benefits from a written letter of explanation with supporting documents.
Assemble this before you apply rather than in response to underwriting conditions. A file that arrives complete moves faster and, in marginal cases, is more likely to be approved — underwriters exercising discretion respond to a well-documented story.

Frequently Asked Questions
How much more does a mortgage cost with bad credit?
On conventional financing, a 620 to 659 score typically adds 0.875% to 1.25% to the rate versus a 760+ borrower. On a $700,000 California loan that is roughly $375 to $540 a month. The penalty accelerates as the score falls, with the steepest jump below 660.
Should I wait to improve my credit before buying?
If you can gain 40 points within about 60 days by paying down revolving balances, waiting usually pays — one pricing tier on a large California loan outweighs two months of appreciation in most markets. If recovery requires two years of post-bankruptcy seasoning, buying now with a non-QM loan and refinancing later often works out better.
Can I refinance later once my credit improves?
Yes, and it is the normal plan. Refinance into conventional pricing once your score passes roughly 680 and any credit event has cleared its seasoning window. Budget 2% to 3% of the loan amount for the refinance, and avoid prepayment penalties — common on non-QM but usually negotiable at application.
Does FHA mortgage insurance ever go away?
Not with less than 10% down — it runs for the life of the loan, unlike conventional PMI which cancels at 20% equity. At roughly 0.55% annually on a $700,000 loan that is about $320 a month indefinitely, which is a strong argument for planning a refinance into conventional.
What documents should I prepare with damaged credit?
Everything a standard file needs, plus a written letter of explanation for each derogatory item with supporting documentation, a paper trail for every large deposit, and explanations for any employment gaps. Assemble it before applying — a complete file moves faster and fares better in marginal decisions.
Is a higher rate worth paying to buy now?
It depends on the alternative. In an appreciating market, the cost of waiting two years can exceed the extra interest paid meanwhile, particularly if you refinance out once credit recovers. In a flat market with a fast credit fix available, waiting is usually cheaper. Run both scenarios rather than assuming.
