How a conventional loan works
A conventional mortgage is not insured by the federal government in the way an FHA loan is. Many conventional loans follow standards set by Fannie Mae or Freddie Mac, though requirements depend on the loan product and lender. Some conventional programs allow eligible borrowers to make a smaller down payment; eligibility can depend on the property, occupancy, income, credit profile, and program rules.
The down payment is only one part of the cash-to-close plan. Budget for closing costs, prepaid expenses, and any reserves you want to keep. A smaller down payment means borrowing more than a larger one would, and may mean private mortgage insurance. Compare the full monthly cost—including principal and interest, taxes, insurance, and any association dues—rather than choosing by minimum down payment alone. Conventional and FHA financing have different qualification criteria and mortgage insurance structures. The right comparison uses the same purchase price and your financial details, and all options remain subject to credit approval and program guidelines.

Costa Mesa's home value sets the local context
Zillow Research reported a home value of $1,424,322 in Costa Mesa in July 2026. That market-wide reference is not a price prediction for a particular property or a personal affordability estimate; use the home you are considering and your full budget to determine what fits.
The conforming limit matters when sizing your loan
For a one-unit property in Orange County, FHFA's 2026 conforming loan limit is $1,249,125 (FHFA Conforming Loan Limits, 2026). This is a loan-amount limit, not a home-price ceiling: your down payment affects how much you borrow relative to the purchase price. If the loan you need is near that threshold, compare the amount financed and applicable loan requirements before settling on a target price.
Plan around taxes and the full monthly payment
The Census ACS 5-Year, 2023 reports a median property tax of $6,096 for Orange County, California. Treat that as context, not the tax bill for a specific Costa Mesa home: property-specific assessments can differ. Include the actual property's taxes, insurance, any mortgage insurance, and association dues in your estimate so a purchase price that looks workable on principal and interest alone does not conceal a higher monthly commitment. I review each new document or underwriting condition with you, explain what it means in plain language, and make time for questions so you understand what is still needed and why.
Use market activity as context, not a deadline
Zillow Research reported 167 homes for sale in Costa Mesa in July 2026 (Zillow Research, July 2026). That inventory snapshot can help frame the choices available, but it does not say how much competition a particular listing will draw. In the same July 2026 snapshot, Zillow Research reported 23 days to pending in Costa Mesa (Zillow Research, July 2026). Use that pace as background while preparing your documents and reviewing an offer, not as a reason to skip checking the property's condition, budget, or contract terms.
What exactly is a conventional loan?
A conventional loan is a mortgage that is not federally insured like an FHA loan; many follow Fannie Mae or Freddie Mac standards, with lender and program requirements varying. In Costa Mesa, compare the loan amount you would need with Orange County's $1,249,125 one-unit conforming limit for 2026 (FHFA Conforming Loan Limits, 2026). The limit concerns the amount borrowed, not the home's purchase price, and your down payment affects the difference.
What is the minimum down payment required for a conventional mortgage?
There is no single minimum that applies to every conventional borrower: some programs allow a smaller down payment for eligible buyers, while requirements depend on the loan, property, and borrower. In Costa Mesa, use the local home-value figure as context rather than treating it as your target price: Zillow Research reported $1,424,322 in July 2026 (Zillow Research, July 2026). Calculate the cash needed for the specific purchase, closing costs, and reserves, then compare that with the resulting loan balance and any mortgage insurance.
What are the key differences between FHA and conventional loans for home buying?
FHA and conventional loans use different qualification criteria and mortgage insurance structures and costs; FHA financing may allow an eligible borrower a smaller down payment, while conventional eligibility depends on its own program requirements. In Costa Mesa, the scale of the purchase matters too: Zillow Research reported a home value of $1,424,322 in July 2026 (Zillow Research, July 2026), while Orange County's 2026 one-unit conforming loan limit is $1,249,125 (FHFA Conforming Loan Limits, 2026). Compare estimated cash to close and ongoing housing costs for both options at the same purchase price; the figures do not determine which loan you qualify for.
