How to Get the Best Purchase Mortgage in California — 2026 Guide

Buying a home in California is one of the biggest financial decisions you will ever make. The mortgage you choose — the interest rate, loan type, down payment, and closing costs — will affect your finances for years or even decades. Getting it right from the start can save you tens of thousands of dollars over the life of your loan.

Bill Lewis at Choice One Mortgage has helped hundreds of California homebuyers navigate this process since 1995. As a mortgage broker, we shop your loan across dozens of competing wholesale lenders to find the best rate and lowest costs for your specific situation. This guide shares the strategies we recommend to every buyer we work with.

1. The Do’s and Don’ts of Buying a Home

The period between deciding to buy a home and closing on your mortgage is financially sensitive. Actions that seem harmless — like buying furniture for your new house or switching bank accounts — can derail your loan approval. Here is what to do and what to avoid.

Do’s: Steps That Help Your Mortgage Approval

• Do pay every bill on time. Credit cards, car loans, student loans — any late payment during the mortgage process can lower your credit score and jeopardize your approval.
• Do keep your bank balances stable. Lenders will verify your accounts multiple times during the process. Large unexplained deposits or withdrawals create red flags that require documentation and can delay your closing.
• Do leave your money where it is. Moving funds between accounts — even your own accounts — creates a paper trail the underwriter must verify. Every transfer requires an explanation and documentation.
• Do gather your documents early. Have your last 30 days of pay stubs, two years of W-2s, two years of tax returns, and 60 days of bank statements ready before you apply. Delays in providing paperwork are the most common reason closings are delayed.
• Do get pre-approved before you start looking. A pre-approval letter from a reputable lender tells sellers you are a serious, qualified buyer. In competitive California markets, offers without pre-approval letters are often rejected without consideration.

Don’ts: Mistakes That Can Kill Your Mortgage

• Don’t buy a car or any large item — not even if you are paying cash. A new car loan adds to your debt-to-income ratio and can disqualify you. Paying cash for a large purchase depletes your reserves, which lenders also verify.
• Don’t quit your job or change employers. Lenders verify your employment right before closing. A job change — even to a higher-paying position — can delay or derail your loan if the new employment cannot be verified in time.
• Don’t open new credit accounts or take on new debt. Every new account creates a hard inquiry on your credit report and changes your debt profile. Even a new store credit card can cause problems.
• Don’t make large or unusual bank deposits. If a family member gives you money for the down payment, there is a specific process (called a gift letter) that must be followed. Random large deposits without documentation will trigger underwriting questions and delays.
• Don’t exaggerate or omit information on your application. Mortgage fraud is a federal crime, and underwriters are trained to identify inconsistencies. Beyond the legal risk, even innocent mistakes create delays when the underwriter asks for clarification.

2. How to Improve Your Credit Scores Before Applying

Your credit score is the single most important factor in determining the interest rate you will be offered. A higher score means a lower rate, which translates directly into lower monthly payments and tens of thousands of dollars in savings over the life of your loan.

Mortgage Credit Scores Are Different From Free Scores

This is something most buyers do not realize: the credit scores you see on Credit Karma, your bank’s app, or other free services are not the scores mortgage lenders use. Free scores use consumer scoring models (like VantageScore), while mortgage lenders use FICO scores developed specifically for the mortgage industry.

We have seen cases where a buyer’s free score showed 720, but their mortgage-specific FICO score came back at 680. That 40-point difference can mean thousands of dollars more in costs over the life of the loan.

At Choice One Mortgage, we perform a soft credit pull that does not affect your scores. This gives us your actual mortgage FICO scores from all three bureaus — Equifax, Experian, and TransUnion — so we are working with real numbers from day one.

Credit Score Tiers and What They Mean for Your Rate

Mortgage pricing is based on credit score tiers. Small differences in your score can have a significant impact on your costs:

• 740 and above: Best available rates with the lowest pricing adjustments
• 720-739: Excellent rates, minimal pricing adjustments
• 700-719: Good rates, but you will start to see some Loan Level Pricing Adjustments (LLPAs)
• 680-699: Rates increase noticeably — the same rate that costs 0 points at 720 may cost 0.5 to 1 point here
• 660-679: Higher rates and costs, fewer program options
• 620-659: Minimum for most conventional loans — significantly higher costs
• 580-619: FHA loans available, but conventional options are limited

We Offer a Free Credit Improvement Program

When we see a client whose score is close to a tier boundary, our team analyzes their credit report and provides specific recommendations to raise their scores — often within 30 to 90 days. This is a free service we offer to every client. Common strategies include:

• Pay down credit card balances to below 30% of the limit — credit utilization is the fastest way to boost scores
• Dispute inaccurate items on the report — errors are more common than you might think
• Avoid new credit applications — each hard inquiry can lower your score by 2-5 points
• Keep old accounts open — even if unused, the length of credit history helps your score

Important: Only let one lender pull your credit report. Ask that lender to share your scores with you, and then provide those scores verbally to other lenders you are comparing. This prevents multiple hard inquiries from lowering your score during the shopping process.

3. How to Determine What You Can Afford

Before you start touring homes and falling in love with properties you may not be able to afford, it is critical to understand your budget. There are two questions to answer:

1. How much will a lender approve you for? This is based on your income, debts, credit score, and down payment.
2. How much are you comfortable spending each month? Just because a lender approves you for $800,000 does not mean you should buy an $800,000 home. Your lifestyle, savings goals, and comfort level matter.

The Debt-to-Income Ratio

Lenders use your debt-to-income ratio (DTI) to determine how much you can borrow. Your DTI is calculated by dividing your total monthly debt payments (including the proposed mortgage payment) by your gross monthly income.

• Front-end DTI: Your housing payment (mortgage, taxes, insurance, HOA) should generally not exceed 28% of your gross monthly income.
• Back-end DTI: Your total monthly debts (housing plus car payments, student loans, credit cards, etc.) should not exceed 43-50% depending on the loan program.

Use our Purchase Loan Scenario Builder to estimate your monthly payment for different purchase prices, down payments, and interest rates. It will help you narrow down your budget before you talk to a lender.

4. Down Payment and Closing Cost Strategies

The down payment is often the biggest hurdle for California homebuyers, especially in high-cost markets like the South Bay, Coachella Valley, and Conejo Valley. But there are more options than most buyers realize.

Down Payment Requirements by Loan Type

• VA Loans: 0% down — the best deal in mortgage lending, available to eligible veterans and active-duty military
• Conventional Loans: As low as 3% down for first-time buyers, 5% for repeat buyers. A 20% down payment eliminates private mortgage insurance (PMI)
• FHA Loans: 3.5% down with a credit score of 580 or higher
• Jumbo Loans: Typically 10-20% down, depending on the loan amount and your financial profile
• CalHFA Programs: California offers down payment assistance for qualifying first-time buyers — ask us about current availability

Putting the Numbers in Perspective

On a $600,000 home in Southern California:

• 3% down (conventional first-time buyer) = $18,000
• 3.5% down (FHA) = $21,000
• 5% down (conventional) = $30,000
• 10% down = $60,000
• 20% down (no PMI) = $120,000

Don’t Forget Closing Costs

In addition to the down payment, you will need to budget for closing costs — typically 2% to 4% of the purchase price. On a $600,000 home, that is approximately $12,000 to $24,000. Closing costs include:

• Lender fees (underwriting, processing)
• Title insurance and escrow fees
• Appraisal fee
• Prepaid property taxes and homeowner’s insurance
• Recording fees

Pro tip: At Choice One Mortgage, we do not charge points. And there are strategies to reduce or eliminate out-of-pocket closing costs — including seller credits (where the seller pays a portion of your costs) and lender credits (where you accept a slightly higher rate in exchange for the lender covering your fees). A good loan officer will help you find the right balance between rate and costs for your situation.

5. How to Choose the Right Loan Officer

This may be the most important tip in this entire guide. The loan officer you choose will have a direct impact on your interest rate, your closing costs, the smoothness of your transaction, and ultimately how much your home really costs you.

Start With Referrals

Ask friends, family, and your real estate agent for recommendations. Someone who had a great experience with their loan officer is the best referral you can get. If you cannot get a personal referral, interview at least two or three loan officers from different lenders.

Questions to Ask Every Loan Officer

• Are you a broker or a bank? (Brokers like Choice One Mortgage can shop dozens of lenders for the best rate; banks can only offer their own products.)
• What makes you different from other lenders?
• What unique programs, rates, or pricing advantages can you offer?
• Do you charge an origination fee, processing fee, or administration fee?
• Can you provide a complete written breakdown of all costs?
• How quickly can you close?

Broker vs. Bank: Why It Matters

When you go to a bank, you are limited to that bank’s products and pricing. When you work with a mortgage broker, your loan is shopped across a network of competing wholesale lenders — often 30 or more. This competition works in your favor, typically resulting in lower rates and fees than what any single bank can offer.

At Choice One Mortgage, we have access to wholesale pricing that is not available to consumers directly. This is one of the primary reasons our clients consistently get better rates than what they are quoted by retail banks and online lenders.

6. Getting a Complete Breakdown of All Costs

Before you commit to a lender, ask for a detailed Loan Estimate — the standardized document that every lender is required to provide. This document breaks down every cost associated with your loan, including:

• Origination charges: Fees the lender charges for processing your loan. Look out for “administration fees” or “processing fees” — not all lenders charge these, and when you see them, they are often pure profit margin.
• Third-party fees: Appraisal, title insurance, escrow, credit report — these are generally similar across lenders.
• Prepaid items: Property taxes, homeowner’s insurance, and prepaid interest — these are not lender fees but are part of your closing costs.
• Points: A point equals 1% of the loan amount. Some lenders build points into their quotes to make the rate look lower. Always compare rates at the same point level.

Watch out for this common tactic: A lender quotes you a great rate but buries a 1-point origination fee in the fine print. On a $500,000 loan, that is $5,000 in additional costs. Always ask: “What is the rate at zero points?”

7. Understanding Your Loan Options in 2026

The mortgage market offers more options than most buyers realize. Here is a quick overview of the programs available to California homebuyers today:

Conventional Loans

The most common loan type. The 2026 conforming loan limit is $766,550 in most California counties, but high-cost counties like Los Angeles ($1,209,750) and Ventura ($1,017,750) have significantly higher limits. Best for buyers with good credit (680+) and at least 3-5% down.

FHA Loans

Government-insured loans with lower credit requirements (580+) and just 3.5% down. Ideal for first-time buyers and those with less-than-perfect credit. FHA loans do require mortgage insurance for the life of the loan.

VA Loans

Zero down payment and no monthly mortgage insurance — available to eligible veterans, active-duty military, and surviving spouses. One of the best mortgage products available, period.

Jumbo Loans

For homes that exceed the conforming loan limit in your county. Competitive rates are available with 10-20% down and strong credit. We work with specialty jumbo lenders who offer flexible terms for high-value California properties.

Non-QM Loans

If you are self-employed, a real estate investor, or have non-traditional income, non-QM loan programs may be the answer. Bank statement loans, DSCR investor loans, and asset depletion programs qualify you based on your actual financial picture rather than rigid W-2 requirements.

Frequently Asked Questions About Buying a Home in California

What credit score do I need to buy a home in California?

The minimum depends on the loan type. Conventional loans typically require 620 or higher, with the best rates available at 740+. FHA loans allow scores as low as 580 with 3.5% down. VA loans have no official minimum, but most lenders prefer 620+. At Choice One Mortgage, we offer a free credit review and our Fresh Start program to help you improve your scores before applying.

How much do I need for a down payment on a California home?

Down payment requirements range from 0% (VA loans) to 20% (to avoid PMI on conventional loans). FHA requires 3.5%, and some conventional programs allow as little as 3% for first-time buyers. On a $600,000 home, a 3.5% down payment is $21,000. California also offers down payment assistance through CalHFA for qualifying buyers.

Should I use a mortgage broker or a bank?

A mortgage broker shops your loan across dozens of competing wholesale lenders, which typically results in lower rates and more program options than any single bank can offer. Banks can only offer their own products at their own prices. At Choice One Mortgage, we have access to wholesale pricing from 30+ lenders — this competition works directly in your favor.

What are the current conforming loan limits in California for 2026?

The standard 2026 conforming loan limit is $766,550 for most counties. However, many California counties are designated high-cost areas with higher limits: Los Angeles County is $1,209,750 and Ventura County is $1,017,750 (Riverside County is $766,550). Loans above these limits require jumbo financing.

Can I buy a home in California if I am self-employed?

Yes. While self-employed borrowers face additional documentation requirements with conventional loans (typically two years of tax returns), our non-QM bank statement loan programs qualify you based on 12 to 24 months of bank deposits instead of tax returns. This is especially valuable for business owners whose tax write-offs reduce their reported income below what they actually earn. Call us at (310) 614-5920 to discuss your options.
