Can you buy a house in San Diego on a $100k salary?

The math lenders actually do

Affordability is a division problem. $100,000 a year is $8,333 per month gross. Lenders qualify you on your debts-vs-income ratio. That is your total monthly debt payments, future house payment included, divided by gross income. Depending on the loan program, credit profile, and the loan review, approvals commonly land in the 40-45% range. That means:

• Total monthly debts allowed: about $3,330-$3,750
• Minus a typical car payment, student loans, and credit card minimums ($300-$600 for many buyers)
• Leaves a housing budget of about $3,000-$3,300 per month, covering principal, interest, property taxes, insurance, mortgage insurance, and any HOA dues

Debt-free? Your ceiling stretches toward the full $3,750. Carrying a $650 truck payment? It compresses hard. This is why two people with the same salary qualify for very different homes. It is also why paying off a car loan can beat a bigger down payment.

What that buys at today's rates (illustrative)

A $450,000 condo runs about $3,400 a month all-in. A $520,000 one runs about $3,900. The math uses a purely illustrative 6.5% rate on a 30-year FHA loan with 3.5% down, plus about 1.15% property taxes, insurance, and FHA mortgage insurance. It does not include HOA dues. The steps in between:

Illustrative estimates only. Actual rates, taxes, insurance, and MI vary by borrower and property. This is not a quote, offer, or approval.

Set that table against the budget above and the honest picture emerges. A debt-free solo buyer stretching to the top of the guidelines can reach $500,000 or more. A buyer with typical debts and a mid-range condo HOA lands closer to $430,000-$480,000. That is the realistic band: about $450k-$520k, depending on taxes, HOA, MI, and your other debts.

One rule of thumb is worth memorizing. At an illustrative 6.5% rate, every $65 or so per month of HOA dues offsets about $10,000 of purchase price. A $325 monthly HOA quietly eats about $50,000 of buying power. That is why the "cheap" condo with sky-high dues can cost more than the pricier one next door.

Where $450k-$520k actually buys in San Diego County

This budget buys condos and townhomes, mostly in East County, South Bay, and inland North County. It does not buy a detached home near the coast, where medians run around $1.0M. Countywide, condos commonly trade between $550,000 and $750,000, but they dip well below that in the right submarkets:

• El Cajon: one of the county's deepest pools of sub-$500k condos. Two-bedroom units are genuinely findable here.
• National City: South Bay value with quick freeway access to downtown. Condos and townhomes regularly fit this budget.
• Escondido: parts of the city offer condos and older townhomes in range, with more space per dollar than coastal North County.
• Vista: select complexes fall within reach, especially east of the 78 corridor.
• Stretch targets: entry condos in Chula Vista and Oceanside sometimes hit the top of the band. They are usually smaller units or higher-HOA buildings, so run the HOA math first.

Is that the fantasy home? No. Is it a real foothold in one of America's priciest markets? Yes. And your payment stays fixed while your renting peers absorb increases forever.

The cash side: where CalHFA changes everything

On a $500,000 condo, FHA's minimum down payment is 3.5%: $17,500. CalHFA's MyHome program covers up to that same 3.5% as a deferred loan with no monthly payment. You repay it only when you sell, refinance, or pay off the home. This cash hurdle stops most $100k earners. It is also the most fixable part. Down payment: covered.

Closing costs run about 2-3%: $10,000-$15,000 on $500,000. The ZIP program (a 0% interest, deferred closing-cost loan of about 2-3% of the main mortgage, which pairs with MyHome) plus a negotiated seller credit can absorb most of that. Many qualifying buyers end up at a few thousand dollars out of pocket: earnest deposit, inspection, appraisal, cushion. That beats $30,000 or more. For the full breakdown, see how much down payment you really need in California.

To qualify for the CalHFA stack, you must be a first-time buyer (no home ownership in the last 3 years). You must live in the home and complete a homebuyer education course. And your income must sit under the limit. That brings us to the good news.

The income limit is not your problem

CalHFA's 2026 income limit for San Diego County is $259,000 ($210,000 in Riverside County). At $100,000, you use less than 40% of the ceiling. Even adding a partner earning $100,000 keeps a household comfortably under it. The limit exists to exclude high earners. It almost never excludes the people asking this article's question. Check current income limits for every county we serve.

One caveat. Dream For All, the shared-appreciation program offering up to 20%, uses lower, program-specific limits: $207,000 in San Diego, $164,000 in Riverside. It requires first-generation buyer status. It ran as a limited voucher round in 2026 (portal closed March 16, vouchers issued from May 20, about $300M in funding). A wind-down is expected at the end of 2026. Treat it as a bonus if the stars align. MyHome is the dependable plan.

The dual-income cheat code

Two incomes buy far more than double. Everything above assumes you buy solo. Add a partner earning $60,000 and household income becomes $160,000. That is $13,333 gross per month, with an allowable debt load around $5,300-$5,700 at the same illustrative guidelines. It supports about $650,000-$750,000, depending on debts and HOA. Townhomes open up. So do entry detached homes in Escondido, Vista, El Cajon, and Chula Vista. And you still sit far under the $259,000 income limit. Why the jump? The fixed costs (taxes, insurance, HOA) do not double.

The trade-offs, stated plainly

You buy a condo, you pay HOA dues, and you carry mortgage insurance. The payment feels heavy at first. Each trade is real, and each is usually worth it.

• Condo, not detached. On $100k solo, holding out for a detached house means leaving the county or waiting for years. The condo is the move. The detached house can be the second purchase, years from now, funded by this one's equity.
• HOA dues are part of your payment. The loan review counts them, and so should you. Get the HOA's dues history, not just the current number.
• Mortgage insurance is real. At minimum down, FHA MI runs for the life of the loan. CalHFA's conventional flavor uses removable PMI but asks a bit more of your credit. This cost buys you entry years earlier. Usually a good trade, but a trade.
• The payment will feel heavy at first. $3,000-plus against $8,333 gross is a commitment. Unlike rent, it is fixed and it builds equity. In ten years it will look like a bargain. San Diego rent will not.

Your action plan

Six steps take you from reading to keys. Start with your debts, not with Zillow.

1. Know your debt picture before Zillow does. List every monthly debt payment. Under $500 or so? You are in strong shape. Higher? Ask which debt to knock out first. That can beat saving more cash.
2. Get pre-approved through a CalHFA-approved lender. Big banks mostly skip these programs and will not mention them. The pre-approval defines your real number.
3. Knock out homebuyer education early. It is a few hours online, required for CalHFA. Do it before escrow, not during.
4. Define the search box. Set a price ceiling and an HOA ceiling (remember: about $65 a month offsets about $10k of price). Pick 2-3 target areas from the list above.
5. Write offers that use the stack. Seller credits toward closing costs are a normal ask. Your agent and lender should coordinate on every offer.
6. Keep your cushion. The goal is to close while your emergency fund never enters the deal.
