Understanding Purchase and Refinance Mortgages
Whether you’re buying your first home, upgrading to a bigger property, or looking to optimize the loan you already have, conventional purchase and refinance mortgages offer flexible pathways for California borrowers. Conventional loans are not backed by government agencies like FHA or VA; instead, they adhere to guidelines set by Fannie Mae and Freddie Mac. This makes them suitable for borrowers with solid credit, verifiable income, and moderate to high down payments.
This guide covers everything you need to know about conventional purchase loans and refinancing options in California, including down payment requirements, credit thresholds, loan types, and reasons to refinance. We also highlight the unique benefits of working with Official Mortgage, where you’ll enjoy no broker fees, no origination fees, and no lender junk fees across all programs.
Conventional Purchase Loans
A conventional purchase loan is used to finance the purchase of a primary residence, second home, or investment property. These loans offer competitive interest rates, fixed or adjustable terms, and a range of down payment options depending on your credit profile and loan size.
Key features:
- Down Payment Requirements: First-time homebuyers may qualify for as little as 3% down under Fannie Mae’s HomeReady or Freddie Mac’s Home Possible programs. Standard conventional loans typically require 5‑10% down. Putting 20% down eliminates mortgage insurance altogether.
- Mortgage Insurance (MI): If your loan-to-value (LTV) ratio exceeds 80%, you’ll pay private mortgage insurance. MI can be canceled once you reach 20% equity or automatically terminates at 78% of the original property value.
- Credit Score: Conventional loans usually require a minimum 620 FICO. Higher scores (740+) lead to better pricing and potentially lower MI rates.
- Loan Limits: For 2026, the baseline conforming loan limit is projected to exceed $766,550, with higher limits in high-cost California counties. Borrowers exceeding these limits may need a high-balance or jumbo loan.
- Occupancy Types: You can use conventional financing for primary homes, second homes, and 1‑4 unit investment properties, though down payment and reserve requirements vary.
- Interest Rates: Conventional loans offer both fixed-rate and adjustable-rate (ARM) options. Fixed-rate loans lock in a rate for the entire term (usually 15 or 30 years). ARMs provide lower initial rates with periodic adjustments, ideal if you plan to move or refinance within a few years.
Refinance Options
Refinancing allows you to replace your existing mortgage with a new loan. Reasons to refinance include securing a lower rate, shortening your term, switching from an adjustable to a fixed rate, removing mortgage insurance, or tapping into home equity. Official Mortgage offers rate-and-term and cash-out refinancing with no broker or origination fees.
Rate-and-Term Refinance
This type of refinance changes either the interest rate, the term length, or both without advancing additional cash to the borrower. Common reasons include:
- Lowering Your Interest Rate: If market rates drop, refinancing can reduce your monthly payment and total interest cost. Even a 0.5% rate reduction may justify refinancing depending on closing costs and timeline.
- Shortening Your Loan Term: Switching from a 30-year to a 15-year mortgage increases your monthly payment but can save tens of thousands of dollars in interest and build equity faster.
- Switching Loan Types: You might refinance out of an ARM into a fixed rate to ensure long-term stability or vice versa to reduce payments in the short term.
- Removing Mortgage Insurance: If you’ve built 20% equity or more, refinancing from an MI-bearing loan to a conventional loan without MI can reduce costs.
Cash-Out Refinance
A cash-out refinance allows you to extract equity from your home by replacing your existing mortgage with a larger loan and taking the difference in cash. Typical uses include:
- Home Renovations: Fund kitchen, bath, or energy-efficient upgrades that may increase your property value.
- Debt Consolidation: Pay off high-interest credit cards or personal loans and consolidate into a lower-rate mortgage.
- Investing: Use equity to purchase another property or invest in business ventures.
- Emergency Fund: Build a cash reserve for unexpected expenses or financial flexibility.
Cash-out refinances typically require:
- LTV Limits: Primary residences may allow up to 80% LTV. For second homes and investment properties, cash-out limits are lower (usually 70–75%).
- Credit Score: Minimum 660 FICO is typical, though higher scores yield better pricing.
- Seasoning: Some lenders require you to have owned the property for at least six months before refinancing.
Preparing for a Conventional Mortgage
Whether purchasing or refinancing, preparation increases your approval odds and ensures better pricing:
- Check Your Credit: Obtain your credit report and score. Dispute any inaccuracies, pay down revolving debt, and avoid large purchases before closing.
- Calculate Your Debt-to-Income (DTI) Ratio: Lenders compare your monthly debts (including the new mortgage) against your gross monthly income. Most conventional loans cap DTI at 45%, though some high-balance programs allow 50% for well-qualified borrowers.
- Save for Down Payment & Reserves: Beyond the down payment, lenders may require 2–6 months of reserves (principal, interest, taxes, insurance). Set aside funds for closing costs and prepaid items as well.
- Gather Documentation: Collect recent pay stubs, W-2s, tax returns, and bank statements. Self-employed borrowers may need profit-and-loss statements or year-to-date financials.
- Get Pre-Approved: A pre-approval letter from Official Mortgage estimates your borrowing capacity and shows sellers you’re serious. Our pre-approval is a soft credit pull and doesn’t impact your score.
No Broker Fees. No Origination Fees. No Junk Fees.
Unlike many mortgage brokers and lenders, Official Mortgage does not charge broker fees, origination fees, or junk fees. We operate on lender-paid compensation, which means more of your money goes toward principal and interest, not closing costs. This pricing model applies whether you’re purchasing a new home or refinancing your existing loan.

Frequently Asked Questions (FAQ)
What’s the minimum down payment for a conventional purchase?
First-time buyers may qualify for 3% down through special programs. Most conventional loans require 5% down, though putting 20% down eliminates mortgage insurance.
When should I refinance my mortgage?
Refinancing makes sense if you can reduce your rate, shorten your term, remove MI, or tap equity. Evaluate your break-even period (closing costs vs. monthly savings) and plan to stay in the home long enough to recoup costs.
Can I use a conventional loan for an investment property?
Yes. You can finance 1‑4 unit investment properties with conventional loans. Down payment and reserve requirements are higher than for primary residences.
What credit score do I need to refinance?
Most conventional refinance programs require a 620+ FICO, but higher scores secure better rates. Cash-out refinances typically require 660+.
Are there penalties for paying off my mortgage early?
Most conventional loans do not have prepayment penalties. You can make extra payments or pay off the loan ahead of schedule without penalty. Always review your closing documents to confirm.
