How Much Money Do You Need to Buy a House in San Diego?

Buying a home in San Diego takes a down payment plus closing costs, and the down payment is the part you can pin down today. San Diego County’s median attached home, meaning a condo or townhome, sold for $659,000 in July 2026 according to the San Diego Association of REALTORS monthly report, so 5% down on that median comes to $32,950. The median detached home sold for $1,150,000 in that same report, where 5% down is $57,500 and 20% down is $230,000.

That spread is the most useful thing a San Diego buyer can understand early. The number you need isn’t one number. It moves with the property type, the loan program, and how much of your savings you’re willing to put in versus keep in the bank. We’ll walk through each piece with real figures, and we’ll be straight about the parts nobody can quote you accurately in a blog post.

How much cash do you actually need to buy in San Diego?

San Diego buyers need a down payment, closing costs, and a small cushion left over after the deal closes. The down payment is the only one of those three we can calculate for you precisely, because it’s just a percentage of the purchase price. Closing costs vary by lender, by loan, and by what you and the seller negotiate, so anyone quoting you a firm percentage in an article is guessing.

Here’s the honest framing. Start with the down payment, because it’s the biggest and most knowable piece. Then get a Loan Estimate from a lender, which is a standardized federal form they have to send you within three business days of your application, and which lists your actual closing costs line by line. That form is the real answer. Everything before it is planning.

A lot of people stop themselves before they ever get to that form. They hear “million dollar median” and assume the door is closed. It usually isn’t, and the next few sections show why.

What San Diego homes cost right now

San Diego County’s housing market splits cleanly into two price worlds. Detached houses had a median sale price of $1,150,000 in July 2026, up 4.6% from a year earlier, while attached homes had a median of $659,000, up 1.4%, both according to the San Diego Association of REALTORS monthly report. That’s a gap of nearly half a million dollars between the two property types in the same county in the same month.

The pace differs too. Detached homes took an average of 33 days to go under contract in July 2026 and attached homes took 43, per the same SDAR report. Detached inventory sat at 2.5 months of supply while attached inventory sat at 4.1 months. More condo supply and slower condo sales generally mean a buyer has more room to think, and more room to negotiate, on that side of the market.

Zoom into the city and the picture gets more competitive. Redfin gives San Diego a Compete Score of 76 out of 100, rating it very competitive, with homes selling for about 1% below list price and going pending in around 27 days as of its most recent three-month window ending June 2026. San Diego’s median sale price per square foot was $686 in June 2026, per Redfin.

The down payment, by price point

The down payment on a San Diego home ranges from nothing to hundreds of thousands of dollars depending on the loan and the property. Below are the down payment amounts at the two county medians, calculated directly from the July 2026 SDAR figures. These are arithmetic, not market statistics, so treat them as a planning starting point.

Down payment	On the $659,000 attached median	On the $1,150,000 detached median
0% (VA)	$0	$0
3%	$19,770	$34,500
3.5% (FHA)	$23,065	$40,250
5%	$32,950	$57,500
10%	$65,900	$115,000
20%	$131,800	$230,000

Down payment amounts calculated from median sale prices in the San Diego Association of REALTORS monthly report, July 2026. Loan program eligibility and minimums vary by borrower and lender.

VA loans allow qualified service members and veterans to buy with no down payment, which in San Diego is a meaningful advantage given how many military families are here. FHA loans allow a minimum of 3.5% down for borrowers who meet the credit requirements. Several conventional programs go as low as 3% down for qualifying buyers. None of that is exotic or hard to access, and it’s the single most common thing people are surprised to learn.

The tradeoff is real, though, and we’d rather say it than skip it. Putting less down means borrowing more, which means a larger monthly payment. On a conventional loan with less than 20% down you’ll also typically pay private mortgage insurance until you build enough equity, which adds to that payment. Less cash up front costs more over time. That’s a legitimate choice, not a mistake, but it should be a choice you make with the numbers in front of you.

Closing costs and the other money that moves

Closing costs in San Diego are real but genuinely variable, so we’re going to tell you what they consist of rather than publish a percentage we can’t stand behind. Your lender’s Loan Estimate is the document that gives you your actual number, and you can get one before you’re anywhere near an offer.

The line items that show up on a San Diego purchase generally include:

• Lender fees. Origination, underwriting, and any discount points you choose to buy.
• Appraisal. The lender orders it to confirm the home is worth what you’re paying.
• Escrow and title. The neutral third party handling the money and the title insurance protecting the ownership record.
• Recording and transfer charges. County fees to record the new deed.
• Prepaids and impounds. Property taxes and homeowners insurance paid ahead, plus interest from your closing date to the end of that month.
• HOA transfer and document fees. Only on condos, townhomes, and homes in an association.

Two other pieces of money move before closing. Your earnest money deposit goes in shortly after your offer is accepted, and the amount is negotiated as part of the offer rather than fixed by rule. That deposit isn’t an extra cost, it credits toward your down payment at closing. You’ll also pay for your own inspections out of pocket during the contingency period, and in San Diego we often recommend more than the basic one, especially on the older homes in the central neighborhoods.

Seller credits are worth asking about too. In a market where detached homes are averaging 33 days to contract and attached homes 43, per SDAR’s July 2026 report, there’s often room to negotiate a credit toward your closing costs. That’s a conversation we have on nearly every deal.

What the monthly payment looks like

The monthly principal and interest payment on a San Diego home at the county medians runs from roughly $3,400 to just over $7,100, depending on property type and down payment. Those figures are standard amortization calculated at the Freddie Mac average 30-year fixed rate of 6.66% for the week ending August 27, 2026, over a 30-year term.

Scenario	Loan amount	Monthly principal & interest
Attached median, 5% down	$626,050	about $4,023
Attached median, 10% down	$593,100	about $3,812
Attached median, 20% down	$527,200	about $3,388
Detached median, 5% down	$1,092,500	about $7,021
Detached median, 10% down	$1,035,000	about $6,651
Detached median, 20% down	$920,000	about $5,912

Principal and interest only, calculated at 6.66% over 30 years using median sale prices from the San Diego Association of REALTORS monthly report, July 2026, and the Freddie Mac Primary Mortgage Market Survey rate for the week ending August 27, 2026. Your rate will differ. These figures exclude taxes, insurance, mortgage insurance, and HOA dues.

Rates move weekly and your personal rate depends on your credit, your down payment, and the loan type, so treat the table as a shape rather than a quote. The Freddie Mac 15-year fixed averaged 5.98% that same week, which is the lever some buyers pull when they can carry a higher payment and want to cut total interest.

Property taxes, insurance, and HOA dues

California’s Proposition 13 sets the base property tax rate at 1% of assessed value, and your assessed value resets to your purchase price when you buy. On a $1,150,000 home that base works out to $11,500 a year, or about $958 a month. On a $659,000 home it’s $6,590 a year, or about $549 a month.

Budget above that base, though. Voter-approved bonds and local assessments get added on top of the 1%, and the total varies by where the property sits. Some newer developments also carry Mello-Roos assessments, which are separate again. Your preliminary title report and the county tax bill for the specific address are where you get the real figure, and we pull those for our buyers before they remove contingencies.

Homeowners insurance and HOA dues round out the monthly picture. Insurance pricing in California has been genuinely unpredictable, so get a quote on the specific property early rather than assuming a number. HOA dues apply to most condos and townhomes and to some detached homes, they’re disclosed during your contingency period, and they can meaningfully change what a given property costs you every month. A lower purchase price with high dues sometimes lands above a higher purchase price with none.

What makes the number smaller

Several levers lower the cash a San Diego buyer needs, and most buyers can use more than one. None of them require a special situation.

• Change the property type. The single biggest lever in San Diego. Moving from the detached median to the attached median cuts the 5% down payment from $57,500 to $32,950, based on the July 2026 SDAR medians.
• Use a low down payment program. VA, FHA, and low down payment conventional loans all exist here and all get used here.
• Negotiate a seller credit. Attached homes averaged 43 days to contract in July 2026 per SDAR, and slower properties are where credits get agreed to.
• Look at down payment assistance. California and San Diego both run assistance programs. Eligibility and funding change, so confirm what’s currently open with a lender who works with them.
• Widen the neighborhood search. Prices vary a lot block to block. Redfin put North Park’s median at $859,701 in June 2026 and Normal Heights at $969,663, two neighborhoods that share a border.

Sources: San Diego Association of REALTORS monthly report, July 2026. Redfin, June 2026. Neighborhood medians move month to month because these are small areas with relatively few monthly sales, so read them as a range rather than a fixed price.

One caution on that last point. Neighborhood medians in central San Diego bounce, sometimes hard, because only a handful of homes sell in each one every month. North Park’s June 2026 median was down 13.6% year over year while Normal Heights was up 9.0%, both per Redfin, and that says more about which specific homes happened to close than about either neighborhood’s direction. Use them to orient yourself, not to price a house.

Where should you start if you’re a few months out?

Start with a lender conversation, before you start looking at homes. A pre-approval tells you the actual price range you qualify for, which is more useful than any median in this article, and getting one costs you nothing. It also produces the Loan Estimate that answers the closing cost question for your specific situation.

Then work backward. Take the price you’re approved for, run the down payment at a few different percentages, add a realistic monthly payment with taxes and insurance, and see which version of that you’d actually be comfortable living with. Plenty of buyers qualify for more than they want to spend, and the gap between those two numbers is where a lot of peace of mind lives.

If you already own something, the equity in it changes the whole calculation. You can get a valuation on your current home to see what you’d have to work with, and if you’re weighing a move we can walk you through what selling looks like in this market.

Frequently asked questions

How much is a down payment on a house in San Diego?

A 20% down payment on San Diego County’s median detached home is $230,000 and a 5% down payment is $57,500, based on the $1,150,000 median in the San Diego Association of REALTORS July 2026 report. On the county’s median attached home of $659,000, 20% down is $131,800 and 5% down is $32,950. VA loans allow qualified buyers to purchase with no down payment at all.

Can you buy a home in San Diego with less than 20% down?

Yes. FHA loans allow a minimum of 3.5% down for qualifying borrowers, several conventional programs go as low as 3%, and VA loans allow zero down for eligible service members and veterans. The tradeoff is a larger loan, a higher monthly payment, and typically mortgage insurance on a conventional loan until you build enough equity.

How much are closing costs when buying in San Diego?

Closing costs vary too much by lender, loan type, and property for any article to quote a reliable figure. The accurate source is the Loan Estimate, a standardized federal form your lender must provide within three business days of your application, which lists every fee. Typical San Diego line items include lender fees, the appraisal, escrow and title, county recording charges, prepaid taxes and insurance, and HOA transfer fees on condos and townhomes.

What is the difference between a condo budget and a house budget in San Diego?

San Diego County’s median attached home sold for $659,000 in July 2026 while the median detached home sold for $1,150,000, per the San Diego Association of REALTORS monthly report, a difference of $491,000. Attached homes also had more supply, at 4.1 months versus 2.5 months for detached, and took longer to go under contract, at 43 days versus 33. Condos and townhomes carry HOA dues that detached homes usually don’t, so compare the full monthly cost rather than the purchase price alone.

What are property taxes on a San Diego home?

California’s Proposition 13 sets the base property tax rate at 1% of assessed value, and your assessed value resets to your purchase price when you buy. Voter-approved bonds and local assessments are added on top of that 1%, and some newer developments carry separate Mello-Roos assessments, so the total depends on the specific address. The county tax bill for that property is the reliable figure.

How competitive is the San Diego market for buyers right now?

Redfin rates San Diego a 76 out of 100 on its Compete Score, described as very competitive, with homes selling for about 1% below list price and going pending in around 27 days over the three months ending June 2026. San Diego County had 2.5 months of supply for detached homes and 4.1 months for attached homes in July 2026, per the San Diego Association of REALTORS. Detached homes received 98.6% of original list price on average and attached homes 97.5%, in that same report.
