Preparing to Buy
Why Preparation Matters More in San Diego
Preparing to buy a home in San Diego is not the same as preparing to buy in most markets. Homes in the most competitive neighborhoods sell in under 20 days. Inventory is tight across the county, with many ZIP codes sitting below 2.0 months of supply. When a well-priced property hits the market in North Park, Hillcrest, or Clairemont, multiple offers can land within days.
In that environment, buyers who show up without a pre-approval letter, a clear budget, and organized finances lose out to buyers who are ready to move. If you have already worked through the decision to buy, the work you do in this phase is what separates serious contenders from people who tour homes for months without ever closing.
Get Pre-Approved Before You Do Anything Else
Pre-approval is the single most important step in preparing to buy a home in San Diego. A pre-approval letter tells sellers and listing agents that a lender has reviewed your income, credit, and assets and is prepared to fund your loan up to a specific amount. Without one, most sellers will not seriously consider your offer.
Pre-approval is different from pre-qualification. Pre-qualification is a rough estimate based on what you tell a lender. Pre-approval involves pulling your credit, verifying your income, and underwriting your financial profile. It carries real weight in a competitive offer situation.
A few San Diego-specific numbers to keep in mind when you talk to a lender:
- Conforming loan limit (2026): $1,149,825 for San Diego County. This is the maximum loan amount Fannie Mae and Freddie Mac will back without requiring a jumbo loan. Most single-family purchases in San Diego fall within this limit.
- FHA loan limit (2026): $1,149,825 for San Diego County. FHA loans require just 3.5% down, making them a strong option for first-time buyers. On a $500,000 condo, that is roughly $17,500 down.
- VA loans: No down payment and no private mortgage insurance for eligible veterans and active-duty service members. With Naval Base San Diego, MCAS Miramar, and Camp Pendleton nearby, a significant share of San Diego buyers qualify. If you have VA eligibility, here are 10 VA loan benefits every San Diego veteran should know.

Know What You Can Afford
The county-wide median single-family home in San Diego is $1,050,000. But the range is enormous. Condos in City Heights start around $460,000. A condo in Bankers Hill or University Heights sits in the mid-$500Ks. Single-family homes in Kensington run over $1 million. A house in La Mesa and a condo in Mission Valley are two completely different financial commitments.
Before you start browsing listings, sit down with your lender and get clear on three numbers:
- Your maximum purchase price. What the lender will approve you for.
- Your comfortable monthly payment. What you can actually afford after accounting for HOA dues, property taxes (roughly 1.1% to 1.25% of purchase price annually in San Diego), insurance, and maintenance. This number is often lower than what the lender approves.
- Your cash on hand. Down payment plus closing costs (typically 2% to 3% of purchase price) plus reserves. Lenders generally want to see two to three months of mortgage payments in reserve after closing.
Knowing these numbers before you tour a single property keeps your search focused and prevents the frustration of falling in love with a home you cannot close on. For a neighborhood-by-neighborhood look at where current prices fall, see our breakdown of the best neighborhoods to buy in San Diego.
Build Your Document File
Lenders will ask for a stack of paperwork during underwriting. Having it organized before you apply speeds up the pre-approval process and avoids delays once you are under contract. Gather the following:
- Income verification: Two years of federal tax returns, W-2s or 1099s, and your most recent 30 days of pay stubs. Self-employed buyers should also have profit-and-loss statements ready.
- Asset statements: Two months of bank statements for all checking, savings, and investment accounts. This includes 401(k), IRA, brokerage, and any other liquid accounts.
- Debt documentation: Current statements for auto loans, student loans, credit cards, and any other recurring debts. Your lender uses these to calculate your debt-to-income ratio.
- Rental history: If you are currently renting, 12 months of cancelled rent checks or bank statements showing payments can strengthen your file.
- Gift letter (if applicable): If family members are contributing to your down payment, the lender will need a signed gift letter confirming the funds are a gift, not a loan.
Protect Your Credit Score
Your credit score directly affects your interest rate, and in a high-cost market like San Diego, even a small rate difference translates to significant money. The difference between a 6.5% and a 7.0% rate on an $800,000 loan is roughly $270 per month, or over $97,000 over the life of the loan.
From the moment you start thinking about buying until the day you close escrow, follow these rules:
- Do not open new credit accounts. No new credit cards, no financing a car, no store credit lines. Each application triggers a hard inquiry that can lower your score.
- Do not make large purchases on credit. A furniture splurge or a new car payment changes your debt-to-income ratio, which can affect your loan approval.
- Do not close existing credit accounts. Closing old accounts shortens your credit history and reduces your total available credit, both of which can drop your score.
- Do pay all bills on time. A single late payment during the mortgage process can derail your approval.
- Do check your credit reports. Pull free reports from all three bureaus (Equifax, Experian, TransUnion) at annualcreditreport.com and dispute any errors before applying.
Down Payment: What It Actually Looks Like in San Diego
Down payment requirements vary by loan type, but here is what the numbers look like at San Diego price points:
| Purchase Price | 3.5% Down (FHA) | 5% Down | 10% Down | 20% Down |
|---|---|---|---|---|
| $500,000 (condo) | $17,500 | $25,000 | $50,000 | $100,000 |
| $750,000 (SFH, entry) | $26,250 | $37,500 | $75,000 | $150,000 |
| $1,050,000 (county median) | $36,750 | $52,500 | $105,000 | $210,000 |

The 20% down payment is not a requirement; it simply eliminates private mortgage insurance (PMI). Many San Diego buyers, especially first-timers, put down 3.5% to 10% and use the remaining cash for closing costs and reserves. If you need to sell a current property to fund your down payment, the timing of that sale adds another layer of planning; talk to your agent early about coordinating the two transactions. The key is talking to a lender early so there are no surprises when it is time to make an offer.
