I recently heard a story about someone who was outbid by another buyer just a day after making their first offer. In San Diego County, it's not uncommon for multiple teams to submit offers on a single property simultaneously, leading to situations where eager buyers sometimes forgo inspection contingencies and sign contracts. This rush is where first-time homebuyers often stumble.

The median sale price in San Diego County was around $952,000 for the three months leading up to June 2026, reflecting a 3.9% increase from the previous year (Redfin, as of June 2026). The average market exposure time has decreased to 27 days, down from 29 days last year, and more than a third of listings sold for above the asking price. These numbers indicate that it's still a seller's market.

One of the first mistakes in such a market is viewing properties without mortgage pre-approval. In competitive areas, offers without a pre-approval letter are often not taken seriously by sellers. If you start looking for a lender only after finding a home you like, it may already be too late.

Having pre-approval doesn't mean you need to rush. In fact, skipping the inspection in the next step is a more common mistake. In a market where homes sell in 27 days, some buyers forgo inspection contingencies for fear of losing their offer, but purchasing an older home with issues like a problematic roof or plumbing can lead to much higher repair costs after moving in.

Undervaluing closing costs is also a frequent mistake. They are typically known to be around 2-5% of the sale price (according to Bankrate's closing cost guide), meaning that for a home priced at $950,000, you could need anywhere from $19,000 to nearly $47,000. If you only account for the down payment and neglect to calculate closing costs, you might find yourself short on funds at the end of the contract.

Competition tends to be more intense in school districts preferred by Korean families. In neighborhoods with good schools, listings can disappear quickly, which can create a sense of urgency. However, it's better to consider long-term living plans, commute distances, and future resale potential before making a decision. I've seen many cases where emotional decisions lead to regret years later.

Property tax burdens are another often-overlooked aspect. In California, Proposition 13 sets the base tax rate at 1% of the assessed value, but when local bonds or special assessments are added, the effective tax rate for new buyers can often rise to between 1.1% and 1.3% (according to the California property tax guide). For families moving from other states, it's wise to check property tax rates in advance to avoid surprises when the tax bill arrives after budgeting based solely on the sale price.

Another common scenario is proceeding with the first lender met without comparing loan terms. The CFPB recommends obtaining quotes from at least three lenders. For homes priced around $950,000, a difference of just 0.25% in interest rates can lead to tens of thousands of dollars in total interest over a 30-year repayment period. In competitive markets, buyers often rush through pre-approval but skip comparing terms, even though the final rates and fees can vary significantly between lenders.

Using all your reserves for the down payment is also risky. Focusing solely on securing funds for closing can leave you without the necessary cash for repairs or living expenses right after moving in. This is especially true if you stretch your down payment to win in a bidding war; it's safer to keep aside at least a few months' worth of living expenses separate from the down payment.

In summary, checking the seven key areas of pre-approval, inspection, closing costs, lender comparison, reserves, property tax, and emotional decision-making seems to be the most practical way to reduce urgency. School district boundaries change frequently, so be sure to verify the assigned school for the address before purchasing, and keep in mind that tax and mortgage conditions can vary by county and lender.
