Maintenance is not optional
Budget about 1 percent of the home's value per year — on a $900K house that is $9,000 annually. It arrives lumpy: nothing for two years, then a $14,000 roof. Coastal homes run higher because salt air eats everything.
Rent vs. Buy in San Diego: The Real Math
The full monthly cost of owning here, the break-even year, and the situations where renting is obviously the smarter move.
Last updated
Quick answer
San Diego is one of the widest rent-versus-own gaps in the country: a home near the $900K median costs roughly $5,800 to $6,500 a month all-in with a typical down payment, while renting a comparable house runs closer to $4,000 to $4,800. That spread means buying is not automatically the winning move — the math turns on how long you stay. Transaction costs are the reason: about 2 to 3 percent to buy and 6 to 8 percent to sell, which is $70,000 to $90,000 of round-trip friction on a median home that appreciation has to erase before you break even. At historically typical appreciation, that puts the break-even somewhere around year five to seven for most San Diego buyers, and longer if you bought at a market peak. What tilts it toward buying: staying seven-plus years, a VA loan with no down payment and no mortgage insurance, an ADU or a rentable room, a low fixed rate, and the fact that your housing cost stops rising while San Diego rents historically have not. What tilts it toward renting: a job or relationship that might move you, a thin emergency fund, a high-HOA condo, or needing every dollar of the down payment for something with better returns.
Renting versus owning a ~$900K San Diego home, monthly, 2026
| Line item | Rent | Buy (20% down) |
|---|---|---|
| Base monthly housing | $4,400 | $4,600 principal & interest |
| Property tax | $0 | ~$940 (about 1.25% annually) |
| Insurance | $25 renters | $180 homeowners |
| HOA or association dues | $0 | $0–$500 depending on property |
| Maintenance and repairs | $0 | ~$600 (1% of value per year) |
| Total monthly | ~$4,425 | ~$6,320 before dues |
| Upfront cost | ~$8,800 deposit and first | ~$180,000 down plus $20K closing |
| Cost to exit | Notice period | 6–8% of sale price |
| Typical break-even | n/a | Year 5–7 |
The costs people leave out of the buy column
Property tax is not just 1 percent
The base rate plus voter-approved bonds and district assessments generally lands around 1.15 to 1.30 percent in San Diego County, and Mello-Roos areas add thousands more on top.
Insurance is rising fast
California's homeowner insurance market has hardened badly. Inland and canyon-adjacent properties are seeing multiples of old rates, and some buyers are landing on the FAIR Plan. Quote it before you remove contingencies.
Closing costs on both ends
Roughly 2 to 3 percent to buy and 6 to 8 percent to sell. That round trip is the single biggest reason short holds lose money even in an appreciating market.
The opportunity cost of the down payment
$180,000 sitting in a house is $180,000 not compounding elsewhere. Any honest comparison has to credit the renter with investing the difference — most online calculators quietly do not.
HOA dues never stop
On a condo, $450 a month is $162,000 over thirty years and it rises with inflation. It belongs in the comparison.
What actually tips the scale
How long you will stay
The dominant variable, and it is not close. Under five years, renting usually wins in San Diego. Past seven, owning usually does. Be honest about your job and your relationships rather than optimistic.
A VA loan changes everything
Zero down and no mortgage insurance removes both the opportunity cost of the down payment and a monthly expense. In a military town this is the most common reason the math flips early.
Rental income on the property
An ADU, a converted garage, or a rented room can cover a large slice of the payment. San Diego's ADU rules are among the most permissive in the state, which is why alley-access lots trade at a premium.
Rent trajectory, not today's rent
Compare a fixed mortgage against rent that has historically risen here over time. Ten years out, the fixed payment is the whole argument for buying — but only if you are still in it.
Your emergency fund
Buying with nothing left over is how people end up putting a water heater on a credit card. Keep three to six months of expenses after closing or you are not actually ready.
The tax deduction is smaller than you think
The standard deduction and the SALT cap mean many San Diego buyers get far less mortgage-interest benefit than the folk wisdom suggests. Run your actual numbers with a CPA instead of assuming.
If you decide to keep renting
Know your tenant protections
Rent caps, just-cause rules, and deposit law — most San Diego renters do not know what applies to their unit.

How to verify anything on this page
- • Prices and rents move. Treat every dollar figure here as a mid-2026 San Diego County snapshot for orientation, then check current listings, a lender quote, and a real HOA statement before you make a decision.
- • Agent licenses are public. Look up any agent or broker by name or license number in the California Department of Real Estate license lookup, which shows status, expiration, and any disciplinary history.
- • Tenant protections stack. State law (the California Tenant Protection Act), the City of San Diego's own ordinance, and county rules can all apply to the same unit. Which ones cover you depends on the building's age, type, and location, so confirm your specific address rather than assuming.
- • Free legal help exists. Legal Aid Society of San Diego and the San Diego Tenants Union take renter questions at no cost, and the city's Housing Instability Prevention Program handles some emergency cases.
- • Down payment assistance programs open and close with funding. The San Diego Housing Commission, the County of San Diego, and CalHFA all run separate programs with separate waitlists — check each one directly rather than relying on a lender's summary.
- • Nothing here is legal, tax, or financial advice. It is a starting map so you know what to ask a professional.
Frequently asked
Is it cheaper to rent or buy in San Diego right now?
Month to month, renting is clearly cheaper in 2026 — roughly $4,400 versus about $6,300 all-in for a comparable median home. Buying wins over a long enough hold, because part of the payment builds equity and the payment stops rising, but on a pure monthly basis the gap here is one of the widest in the country.
How long do I need to stay for buying to make sense?
For most San Diego buyers, five to seven years is the realistic break-even once you account for 2 to 3 percent to buy and 6 to 8 percent to sell. Buying near a market peak or with a high HOA pushes it longer; a VA loan with no down payment or a property with rental income pulls it shorter.
What is the real monthly cost of a $900,000 home?
With 20 percent down at 2026 rates: roughly $4,600 principal and interest, about $940 in property tax, around $180 in insurance, and about $600 a month set aside for maintenance — call it $6,300 before any HOA dues. Less down means a bigger payment plus mortgage insurance.
Does the mortgage interest deduction make buying worth it?
Less than most people expect. With the current standard deduction and the cap on state and local tax deductions, a lot of San Diego buyers see only a modest benefit, and some see none at all. Treat any tax savings as a bonus in your math rather than a load-bearing assumption, and confirm with a CPA.
Should I wait for prices or rates to drop?
Nobody can time it, and the two tend to move against each other — when rates fall, San Diego buyers flood back in and prices firm up. The defensible framing is not 'is this the bottom' but 'can I comfortably hold this payment for seven years.' If yes, timing matters much less than you think.
Is buying a condo better than renting?
Only sometimes. Condos have the smallest price gap over renting but carry HOA dues that never build equity, are more sensitive to association health, and historically appreciate more slowly than detached homes in San Diego. If it is your entry point into a neighborhood you will stay in for years, it can work; as a short-term stopgap, it usually does not.
