Buying your first home in San Diego is exciting, terrifying, and sometimes more confusing than it needs to be. You have been Googling at midnight, doing rough mortgage math, and wondering if buying here is actually possible. Here are some of your most commonly asked questions about the home buying process answered.
1. How much house can I afford in San Diego?
It all depends on your income, your debt, your down payment, and current mortgage rates.
Lenders typically look at two debt-to-income ratios when evaluating affordability:
- Front-end ratio: Your monthly housing payment (principal, interest, property taxes, homeowners insurance, and HOA dues if applicable) compared to your gross monthly income. Most lenders want this at 28% or less.
- Back-end ratio: Your total monthly debt obligations, including housing, car payments, student loans, and credit cards, compared to your gross monthly income. Most conventional lenders prefer this at 36% or below, though they may approve higher ratios depending on your credit score, down payment size, cash reserves, or loan type. FHA loans, for example, can allow back-end ratios up to 43% and higher in some cases depending on the lender and compensating factors.
For example, if your household earns $150,000 per year, your gross monthly income is about $12,500. At 28%, your housing budget would be roughly $3,500 per month. At 36%, your total monthly debt ceiling would be around $4,500. If you have a $500 car payment and $300 in student loans, those reduce what is left for housing.

Get pre-approved before you start seriously shopping. When the right home hits the market, you need to be ready to submit an offer quickly, and waiting to start the financing process after you have found a home puts you at a disadvantage. Your real estate agent can connect you with trusted lenders who can walk you through your options and help you compare loan programs.

2. Is now a good time to buy in San Diego?
First-time homebuyers ask this all the time! It depends on your personal situation more than it depends on the market.
That said, here is where San Diego stands right now, as of June 2026. The market has cooled from the frenzy of 2021 and 2022. Homes are sitting on the market for around 23 days (median) in city of San Diego and 33 days in San Diego county. If you’re in the market for a condo, prices have softened slightly over the past year, giving condo buyers a bit more negotiating room than single-family buyers have.
The case for buying now: every month you wait is a month you are not building equity or benefiting from appreciation. San Diego home prices have appreciated in the vast majority of years historically, and waiting for the perfect moment often means buying at a higher price later with a larger down payment required. It is also worth knowing that when rates drop, more buyers tend to come off the sidelines at the same time, which increases competition and can push prices up. If rates drop, you can always refinance a rate. You cannot refinance a purchase price.
The case for waiting: if your credit needs work, your down payment is not ready, or your job situation is uncertain, waiting six to twelve months to get your financial house in order first is completely reasonable. If buying would stretch you so thin that one unexpected expense, a job loss, a medical bill, a major repair, could put you in financial distress, waiting is the right call. Homeownership under financial stress is worse than renting comfortably.
The worst reason to wait is trying to time the market perfectly. If you want help thinking it through, I put together a cost-of-waiting analysis that shows what the math actually looks like.

3. Should I buy or rent in San Diego?
Buying makes more financial sense if you plan to stay for at least five years or so. The upfront costs of buying, closing costs, moving costs, and immediate repairs, take time to recoup. Owning also gives you something renting does not: the freedom to make the space actually yours, paint the walls, renovate the kitchen, put down roots.
Renting has real advantages too. You are not responsible for repairs and maintenance, your cash stays more liquid, and you have flexibility to move without the complexity of selling. It also makes sense if you are not financially ready to buy, since going into homeownership stretched too thin creates stress.
If you are on the fence, running your actual numbers with a lender is the most useful first step. Most lenders will sit down with you for free and show you the real numbers side by side.
4. What credit score do I need to buy a house?
The minimums by loan type:
- FHA loan: Typically 580+ (with 3.5% down)
- Conventional loan: 620 is a common minimum, meaningfully better rates above 740+
- VA loan: no official minimum, but most lenders want 580-620 depending on their guidelines
If your score is below these ranges, it’s still worth talking to a lender. They can review your credit report, identify what is impacting your score, and outline specific steps to improve it. They can also show how different credit tiers would affect your estimated rate and monthly payment.
One important thing to know before you start shopping is that your financial profile matters all the way through closing. Lenders will re-check your credit and finances before final approval, so changes during this period can impact your loan.
As a general rule, avoid taking on new debt (like financing a car or opening new credit cards), avoid large unexplained deposits or transfers, avoid major purchases on credit, and avoid changing jobs if possible during the loan process. If anything is unclear, always check with your lender before acting.
5. How much are closing costs in San Diego?
Closing costs are the fees and expenses you pay to finalize the purchase of a home. They are separate from your down payment and cover things like the cost of processing your loan, insuring the title, paying the escrow company, and setting up your property tax and insurance accounts. Think of them as the cost of doing the deal itself, separate from the actual price of the home.
They are one of the most common surprises in the homebuying process, not because they are hidden, but because most people are focused on saving for the down payment and do not realize there is a separate set of costs due at closing on top of it.
In California, buyers typically pay around 2% to 3% of the purchase price in closing costs for a conventional loan. On a $950,000 home that is roughly $19,000 to $28,500. In some cases closing costs can be more than that depending on multiple factors, including your loan type, lender fees, and whether you choose to pay discount points to lower your interest rate. Once you are under contract on a specific property, your lender is required to provide a loan estimate within three business days that breaks down your expected costs in detail.
Closing costs generally include:
- Loan origination fees charged by your lender
- Title insurance and escrow fees
- Prepaid homeowner’s insurance
- Prepaid property taxes
- Appraisal fee
- Recording fees
