A San Diego buyer can be approved for an FHA loan and still be better served by a conventional loan. The reverse can also be true. The useful comparison is the cost and flexibility of the two loans for your actual purchase, using the same property, budget and closing date.
I would make that comparison before writing an offer. Once you are in escrow, a change in financing can affect the appraisal, the paperwork and the closing schedule. A little work at the beginning gives you a clearer price range and a better understanding of the cash you need to keep after closing.
Here is how I would evaluate FHA versus conventional financing for a San Diego home purchase.
Start with two quotes for the same purchase
Ask a licensed lender to evaluate both options using the same purchase price, property type, occupancy, loan term and approximate closing date. If one proposal uses substantially more down payment, request another comparison using the cash you actually intend to spend.
According to the Consumer Financial Protection Bureau’s FHA overview, FHA financing can allow a down payment as low as 3.5% and may be competitive for borrowers with smaller down payments or lower credit scores. Borrowers with stronger credit should also look closely at conventional financing.
Conventional does not automatically mean 20% down. Certain eligible buyers can use a HomeReady mortgage with as little as 3% down, subject to the program’s requirements. Other conventional options have their own eligibility and down-payment rules. Ask which program the lender is actually quoting.
The question I would put to the lender is specific: “For this property and this amount of available cash, what makes one option better for me, and where can I see that difference in the numbers?”
Separate the down payment from the amount needed to close
A down payment is only one part of the initial expense. Closing costs, prepaid items, the opening escrow deposit and any financed charges also need to be accounted for. Then there is the money you want available after the keys are delivered.
For a hypothetical $700,000 purchase, a 3.5% down payment is $24,500. That calculation tells you the down payment. It does not tell you the final wire amount, the approved loan balance after any financed premium, or whether the purchase leaves you with adequate reserves.
If a buyer qualifies for a 3%-down conventional program on the same $700,000 purchase, its down payment would be $21,000—a $3,500 difference. That is worth knowing, but it does not settle the comparison. Mortgage insurance, upfront charges, any program income limits and the property’s eligibility can change which option is the better fit.
Ask the lender to show the base loan amount, any upfront mortgage-insurance premium, whether that premium is financed, estimated closing costs and estimated cash to close as separate figures. Financing a charge reduces the amount paid immediately but adds it to the amount borrowed.
For San Diego buyers, the reserve question deserves attention. Moving costs, an insurance deductible, a first-year tax adjustment or a repair can arrive shortly after closing. Using the largest possible down payment may produce a lower payment while leaving the household less prepared for those expenses.
Compare the full monthly payment, including mortgage insurance
Put the two proposals next to each other and identify principal and interest, mortgage insurance, property taxes, homeowners insurance and any association dues. Also identify expenses that will be paid separately from the lender’s monthly bill.
A proposal showing a lower interest rate can still have a higher total monthly cost. Equally, a proposal with a slightly higher principal-and-interest payment may have a different mortgage-insurance cost or a lower upfront expense. Look at the complete proposal before deciding which number matters most.
Use a quote for the actual home’s insurance whenever possible. A placeholder can make both loan estimates look manageable while understating the cost of the property. My guide to obtaining insurance answers before removing contingencies explains what to confirm while purchase deadlines are still open.
Keep the ownership budget separate from the lender’s qualification calculation. A lender may approve a payment that leaves less room than you want for childcare, retirement contributions, irregular income or a future repair. Those are reasons to choose a different price range or financing structure, even when approval is available.
Understand when the mortgage insurance can end
The duration of mortgage insurance can change the longer-term comparison. Under HUD’s rules for FHA case numbers assigned on or after June 3, 2013, annual mortgage insurance generally lasts 11 years when the original loan-to-value ratio is 90% or less, and for the loan term when the original ratio exceeds 90%.
Conventional borrower-paid private mortgage insurance follows different rules. For covered loans, the CFPB explains the right to request cancellation at 80% of the home’s original value, subject to requirements such as current payments and an acceptable payment history. Automatic termination generally relates to the scheduled 78% balance when the borrower is current. Investor rules may also provide other cancellation options.
Ask for the applicable rules in writing. Do not make the purchase depend on a refinance happening in a particular year. A future refinance requires acceptable qualifications, property value and loan terms at that time, along with another set of costs.
For planning, compare the loans over the period you reasonably expect to keep the mortgage. Include upfront loan charges, interest, mortgage insurance and the remaining principal balance. A calculation that counts every principal payment as a lost expense can distort the comparison because those payments also reduce the debt.
For a simpler first check, suppose one otherwise comparable proposal costs $3,600 more upfront and reduces the full monthly payment by $100. It takes 36 months of that payment difference to recover the additional cash outlay. That is a cash-flow break-even illustration, not a complete loan-cost calculation: principal balances, mortgage-insurance changes and the time you actually keep the loan still belong in the final comparison.
Confirm that the property works for the loan
The loan decision and the property decision belong together. Tell the lender whether you are considering a condominium, a detached house, a home needing repairs or a property with another unit. Ask about program eligibility before relying on an approval issued for a different type of property.
With a condo, the association and project review can be important to financing. A borrower’s approval does not complete the building review. See the San Diego condo mortgage and project-approval guide for the documents to address early.
With a house needing work, ask which conditions could require repair before funding and whether a renovation-loan option would be more appropriate. An appraisal also serves a different purpose from your independent home inspection; arrange the inspection and review the findings on their own merits.
Finally, have the lender confirm the current county limit, unit count and program requirements for the proposed loan amount. San Diego’s price range makes those details relevant, and a general online example cannot answer them for a specific purchase.
Bring financing into the purchase strategy
If a seller is willing to contribute toward closing costs, ask how much of that credit can actually be used under the proposed loan and what expense it would cover. A negotiated amount has value only to the extent the transaction permits you to use it.
For that comparison, consider the differences between a seller credit, a price reduction and a mortgage buydown. The best structure depends on your immediate cash needs, monthly budget and expected ownership period.
Before submitting an offer, I would want five items resolved: the available programs, the cash to close, the complete monthly cost, the property-specific requirements and the time the lender needs to close. Those answers give the real estate and lending sides a shared plan.

Frequently asked questions
Is an FHA loan always easier or cheaper for a San Diego buyer?
No. FHA may be a useful option depending on credit, down payment and the property, but the comparison should include the complete payment, upfront costs and mortgage-insurance duration. Ask a lender to evaluate both FHA and conventional financing for the same purchase.
Do I need 20% down for a conventional loan?
No. Eligible buyers may qualify for conventional programs with smaller down payments, including certain programs allowing 3% down. Eligibility, mortgage insurance and the complete cost must be reviewed for the specific borrower and property.
Does FHA mortgage insurance disappear when the home gains equity?
For FHA case numbers assigned on or after June 3, 2013, the annual premium generally follows an 11-year or full-loan-term schedule based on the original loan-to-value ratio. Appreciation alone does not apply the conventional private-mortgage-insurance cancellation rules to an FHA loan.
