What buyers should focus on instead
A lot of buyers in San Diego start with the same assumption: that owning a home is simply out of reach. They picture a 20% down payment on a $700,000 or $800,000 home, add up the numbers, and convince themselves it's just not possible right now.
It's understandable. Headlines about San Diego home prices are hard to ignore, and social media has a way of making homeownership look like something only people with serious wealth can pull off.
But here's what those headlines tend to leave out.
People buy homes in San Diego every day with far less cash upfront than most renters assume. Some are using low-down-payment conventional loans. Some are using FHA financing. Veterans and active military buyers are purchasing homes with no down payment at all. None of that means buying is easy, and it definitely doesn't mean every buyer is ready. But it does mean the conversation is usually more nuanced than "I need hundreds of thousands of dollars saved before I can even start thinking about this."
A lot of first-time buyers in San Diego assume they're behind financially when in reality they're simply comparing themselves to unrealistic expectations. Most people who own homes today didn't start with a massive savings account. They started with a plan.
This guide is meant to help you understand what buying a home in San Diego actually costs, what matters most, and how to think about it realistically.
Can You Buy a Home in San Diego Without 20% Down?
Yes. Most buyers in San Diego do not put 20% down. That's not a workaround or a compromise. It's simply how the majority of buyers purchase homes.
FHA loans, low-down-payment conventional loans, and VA loans all exist specifically because most buyers don't have 20% sitting in savings. Waiting until you do isn't always financially smart, and for many buyers it isn't necessary.
How Much Money Do You Actually Need?
The short answer: it depends on your loan type, the purchase price, and your overall financial picture.
Here's a general range of what buyers typically need to get started:
FHA loan: Minimum 3.5% down (with a credit score of 580 or higher)
Conventional loan: Typically 3% to 5% down for first-time buyers
VA loan: No down payment required for qualifying veterans and active military
On a $650,000 home, that translates roughly to:
3.5% down: About $22,750
5% down: About $32,500
10% down: About $65,000
But the down payment is only one piece of the picture. Buyers also need to plan for closing costs, reserves, and the ongoing monthly payment. We'll cover all of that below.
In Simple Terms
Many San Diego buyers purchase homes with:
Less than 20% down
FHA financing at 3.5% down
Conventional loans with 3 to 5% down
VA financing with no down payment for eligible buyers
But the bigger question is not just: "Can I qualify?"
It's: "Can I comfortably sustain ownership long term?"
Why So Many Buyers Think They Need 20% Down
The 20% figure comes up constantly, and it creates a lot of unnecessary discouragement. It's worth understanding where it comes from.
Where the 20% Myth Comes From
Putting 20% down does have real advantages. It eliminates private mortgage insurance (PMI), typically results in a lower monthly payment, and shows lenders you have significant skin in the game. For older generations, it was closer to the standard.
But the lending landscape has changed significantly. Low-down-payment options exist specifically because most buyers don't have 20% sitting in savings, and waiting until they do isn't always the smartest financial move.
The 20% rule also gets passed along secondhand through parents, relatives, and well-meaning friends who bought homes in different market conditions. It's not bad advice exactly, it's just not the only path.
Most buyers do not put 20% down.
Why Many Buyers Intentionally Use Lower Down Payments
Preserving cash after closing is often a smarter priority than maximizing your down payment. Here's why some buyers choose to put less down:
Keeps emergency savings intact so you're not starting homeownership broke
Allows buyers to enter the market sooner rather than spending years saving
Leaves room for repairs, moving costs, and early maintenance needs
Creates flexibility for a future move-up purchase
That said, putting less down does come with real tradeoffs. Your monthly payment will be higher, you'll pay more in interest over time, and you may carry PMI for several years. None of that is automatically a bad deal, but it's worth understanding before you commit.
A Real-World Example
A buyer renting in Clairemont originally assumed they needed nearly $150,000 saved before buying was even possible. After speaking with a lender, they found that a conventional low-down-payment option allowed them to purchase a smaller condo in La Mesa while still keeping reserves intact. The monthly payment was higher than their rent, but not by as much as they expected. Two years later, they had equity and options they wouldn't have had if they'd kept waiting.
That's not a guarantee of how every purchase works out. But it is a pattern worth considering when the assumption is that buying is simply out of reach.
What Buyers Actually Need to Budget For
Down payment gets most of the attention, but it's not the only number that matters. Here's a realistic breakdown of what buyers should plan for.
Down Payment
FHA: 3.5% minimum (with qualifying credit)
Conventional: 3% to 5% or more for first-time buyers
VA: 0% for eligible veterans and active military
Closing Costs
Typically 2% to 3% of the purchase price in San Diego. On a $650,000 home, that's roughly $13,000 to $20,000 in addition to your down payment. Generally includes:
Lender fees (origination, underwriting)
Escrow and title fees
Home inspection and appraisal
Prepaid property taxes and homeowners insurance
Some buyers negotiate seller credits to help offset these costs, though that depends on market conditions at the time.
Monthly Payment
Your full monthly housing cost includes more than principal and interest:
Principal and interest: Determined by your loan amount and rate
Property taxes: Roughly 1.1% to 1.25% of purchase price annually in California
Homeowners insurance: Varies by property and coverage
HOA fees: Required for condos and many planned communities
PMI: Required on most loans with less than 20% down
The monthly payment matters more than the purchase price alone.
Emergency Reserves
Buyers should still have savings left after closing for:
Repairs and maintenance surprises
Moving costs
Appliance replacements
Unexpected expenses in the first year
Having a few months of mortgage payments set aside after you close isn't just smart, it's what keeps a tough month from turning into a crisis.
What Buyers Often Forget
Many first-time buyers focus almost entirely on:
The down payment
Qualifying for the loan
Interest rates
But long-term success usually depends more on:
Sustainable monthly payments
Emergency savings after closing
Stable income and manageable debt
Realistic expectations about ownership costs
Buying something manageable, not just something impressive
What PMI Actually Means
Private mortgage insurance gets a bad reputation, but it's worth understanding what it actually is before writing it off.
PMI protects the lender if you default on the loan. When you put less than 20% down, lenders require it to offset the additional risk. It typically costs between 0.5% and 1.5% of the loan amount annually, adding roughly $250 to $750 per month on a $600,000 loan depending on your credit and down payment.
When does it go away? On conventional loans, you can request removal once you reach 20% equity, and it cancels automatically at 22% under federal law.
For many buyers, paying PMI for a period of time is a reasonable trade-off compared to waiting years to save a larger down payment while prices continue moving. It's a cost worth understanding, not automatically a dealbreaker.
Why Monthly Payment Matters More Than Purchase Price
Most buyers focus on purchase price first. But what you can afford to pay each month is usually the more important number.
Two buyers can purchase homes at the same price and end up with very different monthly payments depending on their interest rate, loan type, down payment, HOA, and insurance situation. Before you fall in love with a price range, get clear on a monthly payment that actually fits your life.
That means accounting for:
Your take-home income, not just your gross salary
Your existing debts and obligations
What you currently spend on rent and how much adjustment you can absorb
Your savings goals outside of housing
The lifestyle tradeoffs you're actually willing to make
Payment Shock Is Real in San Diego
Moving from renting to owning in San Diego often comes with a significant increase in monthly housing costs, especially for buyers who've been renting in stabilized situations for a long time. Beyond the mortgage itself, ownership adds maintenance, higher utilities in some cases, HOA fees, and the ongoing responsibility of the property.
None of that is a reason not to buy. But going in with realistic expectations makes a real difference in how the first year of ownership feels.
What First-Time Buyers Often Get Wrong
Working with buyers in San Diego County, the same patterns show up repeatedly. Here are the mistakes worth knowing about before you start your search:
Focusing only on the down payment while ignoring whether the monthly payment is sustainable
Draining all savings to close, then having nothing left for repairs or emergencies
Buying based on emotion rather than long-term financial fit
Assuming renting is automatically the safer choice
Comparing themselves to older homeowners who bought in different market conditions
Waiting for perfect conditions that rarely arrive
Ignoring East County and other accessible entry points in favor of coastal areas they can't yet afford
Overlooking the long-term equity and stability benefits of ownership, even in a modest first home
That last one comes up a lot. Buyers sometimes pass on realistic opportunities because they've set expectations based on an ideal that isn't within reach yet. The result is they stay in the rental market longer than necessary while the window slowly narrows.
Your First Home Does Not Need to Be Perfect
This is probably the thing I find myself saying most often to first-time buyers.
Most of the homeowners you know who are in a comfortable position today didn't start there. They started with something smaller, less ideal, or not in their preferred location. They built equity over time and used it to move up.
Your first home does not need to be perfect. It needs to be manageable.
In San Diego County, there are communities that offer more realistic entry points for first-time buyers, including parts of East County like:
Alpine: More rural, larger lots, older homes, and lower price points relative to coastal communities
Santee and Lakeside: Good mix of affordability and accessibility for families
El Cajon and La Mesa: Diverse inventory with more options at lower price points depending on the market
There are real tradeoffs to East County, including commute time, wildfire insurance considerations in some areas, and older properties that may have septic or well water systems requiring more buyer education. But for buyers willing to look beyond the coast, ownership often becomes more realistic sooner.
The goal isn't buying the perfect home. The goal is buying the right home for where you are financially right now, and building from there.
What Buyers Should Focus On Instead
Instead of fixating on whether you have "enough" saved, start asking better questions:
Can I comfortably afford this monthly payment without straining my budget?
Will I still have reserves after closing for repairs and emergencies?
Is this purchase improving my long-term financial position?
Am I buying something functional that I can realistically sustain?
Does this purchase create future flexibility, or does it lock me in uncomfortably?
Am I buying strategically, or emotionally chasing something I'm not ready for?
The goal is not simply buying a home. The goal is buying responsibly.
When Buying May Not Make Sense Yet
This is a section I include because I think it's important to say honestly.
Not every buyer is ready, and there's no shame in that. Pushing into a purchase before you're financially prepared usually creates more problems than it solves.
It may make sense to wait if:
Your income is unstable or you're in a transitional employment situation
You don't have emergency savings separate from your down payment
You're carrying significant high-interest debt that would strain your budget further
You're buying primarily out of social pressure rather than financial readiness
You're planning to move again within two to three years
Qualifying would require stretching uncomfortably past what you can sustain
Buying before you're financially ready can create more stress than stability. There's real value in waiting until the timing is actually right for your situation.
Real Estate Ownership Usually Builds Slowly
Most homeowners didn't build long-term wealth through perfect timing or a massive upfront investment. They built it gradually, through years of principal paydown, modest appreciation over time, and the simple stability of not having a landlord raise their rent or sell the property out from under them.
Ownership creates options over time.
The buyer who purchases a modest home in Santee or El Cajon today and holds it for seven to ten years typically has something real to work with when they're ready to move up. The renter who kept waiting for the perfect moment or the perfect home often finds the gap has only gotten wider.
That's not a guarantee. Real estate involves risk, and no one can promise appreciation. But it is a pattern worth recognizing when you're trying to think clearly about whether now is the right time.
Frequently Asked Questions
Do you really need 20% down to buy a home in San Diego?
No. Most buyers do not put 20% down. FHA loans require as little as 3.5%, conventional loans are available with 3% to 5% down for qualified buyers, and VA loans require no down payment for eligible veterans and military members. 20% eliminates PMI and lowers your monthly payment, but it is not a requirement to purchase.
How much are closing costs in San Diego?
Closing costs typically run between 2% and 3% of the purchase price, though they can vary. On a $650,000 home, that is roughly $13,000 to $20,000 in addition to your down payment. Some buyers negotiate seller credits to help offset these costs.
What credit score do you need to buy a home?
FHA loans are available with credit scores as low as 580 with 3.5% down. Conventional loans typically require a minimum score in the 620 to 640 range, though better scores unlock better rates. Your credit profile affects both your loan options and your interest rate.
Is PMI bad?
PMI adds to your monthly payment and does not directly benefit you as the buyer. But for many buyers, paying PMI for a few years while building equity is more financially sound than waiting years to save a 20% down payment. It's a cost worth understanding, not automatically a dealbreaker.
Is buying with 5% down risky?
It depends on your overall financial situation. Buying with a smaller down payment means a higher monthly payment, less equity cushion early on, and PMI. If you have stable income, manageable debt, and reserves after closing, 5% down is a reasonable and common path. The risk increases when buyers stretch their budget too aggressively or have no savings left after closing.
Should first-time buyers use FHA loans?
FHA loans can be a good fit for buyers with lower down payments or credit profiles that don't qualify for conventional financing. They do require mortgage insurance for the life of the loan in most cases, which makes them more expensive long-term. A good lender will walk you through the comparison based on your specific numbers.
What monthly payment is realistic in San Diego?
It varies based on purchase price, down payment, interest rate, property taxes, HOA fees, and insurance. Buyers purchasing in the $550,000 to $700,000 range with moderate down payments are often looking at total monthly housing costs somewhere between $4,000 and $5,500 or more. Getting pre-approved with a lender gives you a real number based on your situation.
Is East County more affordable for first-time buyers?
Generally, yes. Communities like Alpine, Santee, Lakeside, El Cajon, and La Mesa tend to have lower price points than coastal San Diego. There are tradeoffs including longer commutes and in some areas additional considerations like wildfire insurance or properties with well water or septic systems. For buyers open to those tradeoffs, East County can offer a more realistic entry into ownership.
