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

The math lenders actually do

Forget vibes — affordability is a division problem. $100,000 a year is $8,333 per month gross. Lenders qualify you on your debts-vs-income ratio: your total monthly debt payments — future housing payment included — divided by gross income. Depending on the loan program, credit profile, and the loan review, approvals commonly land in the 40–45% debts-vs-income range (that share of your gross monthly income going to all debt payments combined). That means:

• Total monthly debts allowed: roughly $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

If you're debt-free, your ceiling stretches toward the full $3,750. If you're carrying a $650 truck payment, it compresses hard. This is why two people with identical salaries qualify for very different homes — and why paying down a car loan is sometimes worth more than a bigger down payment.

What that buys at today's rates (illustrative)

Using a purely illustrative 6.5% rate on a 30-year FHA loan with 3.5% down, roughly 1.15% property taxes, insurance, and FHA mortgage insurance — but before HOA dues — the all-in monthly payment lands approximately here:

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

Read that against the budget above and the honest picture emerges: a debt-free solo buyer stretching to the top of the guidelines can reach the $500,000+ neighborhood; a buyer with typical debts and a mid-range condo HOA lands closer to $430,000–$480,000. Hence the realistic band of roughly $450k–$520k depending on taxes, HOA, MI, and your other debts.

One rule of thumb worth memorizing: at an illustrative 6.5% rate, every ~$65/month of HOA dues offsets roughly $10,000 of purchase price. A $325/month HOA quietly eats about $50,000 of buying power — which is why the "cheap" condo with sky-high dues can be more expensive than the pricier one next door.

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

This budget doesn't buy a detached home near the coast — medians there run around $1.0M. It buys condos and townhomes, which in San Diego commonly trade between $550,000 and $750,000 countywide but dip meaningfully 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 occasionally hit the top of the band — usually smaller units or higher-HOA buildings, so run the HOA math first.

Is that the fantasy? No. Is it a real foothold in one of America's most expensive markets — with a fixed payment while your rent-paying peers absorb increases forever? Yes.

The cash side: where CalHFA changes everything

Here's the part that stops most $100k earners — and the part that's most fixable. On a $500,000 condo, FHA's minimum down payment is 3.5%: $17,500. CalHFA's MyHome program provides up to that same 3.5% as a deferred loan with no monthly payment, repaid only when you sell, refinance, or pay off the home. Down payment: covered.

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

To qualify for the CalHFA stack you'll need to be a first-time buyer (no home ownership in the last 3 years), live in the home, complete a homebuyer education course, and come in under the income limit — which 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're using less than 40% of the ceiling. Even adding a partner earning $100,000 keeps a household comfortably eligible. 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), requires first-generation buyer status, and ran as a limited voucher round in 2026 (portal closed March 16, vouchers issued from May 20, roughly $300M in funding) with a wind-down 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

Everything above assumes you're buying solo. Add a partner earning $60,000 and household income becomes $160,000 — gross monthly of $13,333 and an allowable debt load around $5,300–$5,700 at the same illustrative guidelines. That supports roughly $650,000–$750,000 depending on debts and HOA — which unlocks townhomes and even entry detached homes in Escondido, Vista, El Cajon, and Chula Vista, while still sitting far under the $259,000 income limit. Two modest incomes buy dramatically more than the sum of their parts suggests, because the fixed costs (taxes, insurance, HOA) don't double.

The trade-offs, stated plainly

• Condo, not detached. On $100k solo, insisting on a detached house means either leaving the county or waiting indefinitely. The condo is the move; the detached house is the second purchase, years from now, funded by this one's equity.
• HOA dues are part of your payment. Underwriting 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. It's a cost of entering years earlier — usually a good trade, but a trade.
• The payment will feel heavy at first. $3,000+ against $8,333 gross is a commitment. The difference from rent: it's fixed, it builds equity, and in ten years it will look like a bargain — San Diego rent will not.

Your action plan

1. Know your debt picture before Zillow does. List every monthly debt payment. Under ~$500? You're in strong shape. Higher? Ask which debt to eliminate first — it may beat saving more cash.
2. Get pre-approved through a CalHFA-approved lender. Big banks mostly don't offer these programs and won't mention them. The pre-approval defines your real number.
3. Knock out homebuyer education early. A few hours online, required for CalHFA — do it before you're in escrow, not during.
4. Define the search box. Price ceiling, HOA ceiling (remember: ~$65/month ≈ $10k of price), and 2–3 target areas from the list above.
5. Write offers that use the stack. Seller credits toward closing costs are a negotiating line item, not a favor. Your agent and lender should coordinate on every offer.
6. Keep your cushion. The goal isn't to close with $0 — it's to close while your emergency fund never enters the transaction.
