San Diego County: How to Buy a Starter Home Under $1 Million (October 2026)

By Dr. Hamid Rowshan, Choice of America

How to buy a San Diego County starter home under $1 million as entry-level prices dip 1.1%: ZIPs to watch, payment math at 7.24%, FHA and offer strategy.

San Diego's entry-level homes are getting a little cheaper while the rest of the market holds firm. Axios San Diego reported on October 13 that, according to the First American Data & Analytics Home Price Index, prices for "starter homes" (homes selling for less than $1 million) fell 1.1% from a year earlier, while homes between $1 million and $1.496 million, and homes above $1.496 million, each rose about 0.5%. First American put the median starter-home price at $775,000. San Diego Association of Realtors president Karen Van Ness told Axios that rates near 7.3% are "the kicker," and First American chief economist Mark Fleming said weaker demand for cheaper homes is what has tipped this part of the market toward buyers.

Two other pieces of news point the same way. The California Association of Realtors reported on October 19 (via City News Service and KPBS) that San Diego County single-family sales in September were down 12.2% from a year ago and down 6% from August. And Freddie Mac's weekly survey put the average 30-year fixed rate at 7.24% for the week of October 29, down from 7.32% the week before and 7.40% on October 15.

Fewer buyers, softer entry-level prices and rates easing a little: for a first-time buyer with steady income, that is the most room to negotiate San Diego has offered in years. Here is how to use it, step by step.

About one listing in five had a price cut in September, and pending sales were nearly 10% below a year ago. That is the opening for a well-prepared buyer.

Where the under-$1 million homes are

Realtor.com also publishes the same figures by ZIP code. Of the 81 San Diego County ZIP codes with at least 15 active listings in September 2026, 49 had a median listing price under $1 million. Here are ten ZIPs with a median between about $660,000 and $770,000 (Realtor.com flags a few ZIP figures as less reliable month to month; those are marked with an asterisk):

Notice that Santee, Paradise Hills and Eastlake all had price cuts on more than 22% of listings. Those are the ZIPs where a patient offer below asking is most likely to be taken seriously.

The payment math at 7.24%

Principal and interest (P&I) on a 30-year fixed loan:

PriceDown paymentLoanMonthly P&I at 7.24%
$888,450 (county median listing)20% ($177,690)$710,760$4,844
$775,000 (First American starter median)20% ($155,000)$620,000$4,225
$699,450 (Santee 92071 median)20% ($139,890)$559,560$3,813
$663,223 (92154 median)20% ($132,645)$530,578$3,616

Formula: P&I = L × r ÷ (1 − (1 + r)^−360), where L is the loan amount and r is the annual rate divided by 12.

Buying at the $775,000 starter median instead of the $888,450 county median saves about $619 a month in P&I with 20% down. Property tax (California's base is 1% of the purchase price plus local bonds and assessments), homeowners insurance, any HOA or Mello-Roos, and utilities come on top.

With 3.5% down (FHA). San Diego County's 2026 FHA one-unit loan limit is $1,104,000, so every home in the table above fits. FHA adds an upfront premium of 1.75% of the base loan (usually financed) and an annual premium. On a $775,000 home, 3.5% down is $27,125; the loan with the upfront premium is about $760,963, P&I is about $5,186, and the annual premium (0.75% for a base loan above $726,200) adds about $467, for roughly $5,653 a month before tax and insurance. On the $663,223 home in 92154, 3.5% down is $23,213, and P&I plus the 0.55% annual premium comes to about $4,731.

How to buy a starter home in San Diego County: step by step

Step 1: Set your price from the payment, not the other way around. Pick the total monthly housing cost you can live with (P&I, tax, insurance, HOA and mortgage insurance), then work backward with the formula above. Many lenders want total housing cost at or below about 28% to 36% of gross monthly income, and total debts at or below roughly 43% to 50%, depending on the loan. As a rough guide, $4,225 of P&I alone is 36% of a gross income of about $140,800 a year, before tax and insurance.

Step 2: Get fully underwritten before you shop. In a market with 12% fewer sales, sellers worry about deals falling apart. A pre-approval where the lender has already checked your income, assets and credit makes your offer look like a sure thing, which is worth real money in negotiation.

Step 3: Choose the loan that fits your cash. Compare 20% down conventional, 5% to 10% down conventional with private mortgage insurance, FHA at 3.5% down, and VA at zero down if you are eligible. Ask each lender for a Loan Estimate on the same day, so you compare rate, points and fees side by side.

Step 4: Search by ZIP and by price cuts. Use the ZIP table as a starting map, then set listing alerts for homes priced up to about 10% above your target in ZIPs with high price-cut shares (Santee, Paradise Hills, Eastlake). Homes that have sat past the county's 46-day median are the ones whose sellers are most open to offers.

Step 5: Look at the whole monthly cost of each home. Two homes at the same price can differ by hundreds of dollars a month. Ask for the HOA budget and dues history (Van Ness told Axios some HOA dues have risen 60% to 70% since 2021), check for Mello-Roos in newer areas such as Otay Ranch and Eastlake, and get an insurance quote before you write the offer.

Step 6: Write the offer around the payment. With one in five listings already cut, ask for one of these: a lower price, seller-paid closing costs, or a seller-paid rate buydown. Run all three through the formula. A lower price lowers your tax and your down payment for the life of the loan. A buydown lowers the payment for one to three years. Choose the one that fits your plan.

Step 7: Protect yourself with contingencies. Keep your inspection, appraisal and loan contingencies, even in a slower market. Get a general inspection, a sewer-line scope for older homes in La Mesa, El Cajon and Spring Valley, and a termite report. Ask for repairs or a credit based on what the inspection finds.

Step 8: Lock your rate at the right time. Rates fell three weeks in a row through October 29. Ask your lender about a lock with a float-down option, so you keep a lower rate if rates keep easing before you close.

Step 9: Plan the first year of ownership. Keep a reserve of at least two to three months of the full payment after closing, and budget about 1% of the home's value a year for repairs. If rates fall later, a refinance can lower the payment, but never buy a home you can only afford if rates drop.

Mistakes to avoid

  • Shopping by list price instead of by total monthly cost.
  • Waiving the inspection or appraisal contingency to win a home in a market where sellers are already cutting prices.
  • Skipping the HOA documents on a condo or townhome.
  • Using all your savings for the down payment and leaving no reserves.
  • Assuming the ZIP median is the price of the home you want; medians include condos and townhomes.

Quick checklist

  1. Monthly budget set and run through the formula.
  2. Fully underwritten pre-approval in hand.
  3. Loan Estimates from at least two lenders.
  4. Target ZIPs and listing alerts set.
  5. HOA, Mello-Roos and insurance checked for each home.
  6. Offer strategy chosen: price cut, closing credit or buydown.
  7. Inspection, appraisal and loan contingencies kept.
  8. Rate lock plan agreed with your lender.
  9. Cash reserve left after closing.

What this means day to day

For a San Diego renter, a $663,000 to $775,000 home in Otay Mesa, Santee, Chula Vista or El Cajon is still a big stretch at 7.24%. But it is a stretch you can now negotiate. Sellers in these ZIPs are cutting prices, sales are down from a year ago, and rates are edging lower. The buyers who do best are the ones who know their number, have their loan ready and make clear, well-backed offers.
