I recently heard a story about a family who, just two months after moving in, had their water heater break down, requiring $2,200 in repairs. They had nearly exhausted their emergency fund to cover the down payment, so they had to quickly incur credit card debt. It's more common than you might think for first-time homebuyers to pour their emergency funds into the down payment.

As of June 2026, the median sale price in San Fernando is $740,597, which is an 8.9% increase from the previous year (Redfin, June 2026). The average market exposure time is 58 days, but the competition index for ZIP code 91340 is rated at 80 out of 100, classifying it as a very competitive market. Popular listings are selling for 2% above the asking price within 21 days.

In such a market, the belief that you need to maximize your down payment to get your offer accepted can lead to situations where buyers invest all their emergency funds. However, right after moving in, unexpected expenses tend to pile up. When moving costs, minor repairs, and appliance replacements coincide, there will inevitably come a moment when it's hard to manage without an emergency fund that covers several months' worth of living expenses.

When budgeting, it's a common mistake to only calculate the mortgage principal and interest while overlooking property taxes, homeowners insurance, and maintenance costs (according to the CFPB Homebuying Guide). In California, the base tax rate is 1% under Prop 13, but when local bonds are added, the effective tax rate often rises to between 1.1% and 1.3%. For a home priced around $740,000, this means annual property taxes could range from $8,100 to $9,600, which must be included in the monthly budget.

It's also common to underestimate closing costs. Based on the guideline that they typically range from 2% to 5% of the sale price (Bankrate), a home priced around $740,000 would require at least $14,800 to nearly $37,000. If you don't calculate the down payment, emergency fund, and closing costs separately, you could find yourself short on funds right before closing.

There are also cases where buyers neglect to manage their credit scores or debt-to-income ratios right before signing the contract. There have been instances where, feeling relieved that their offer was accepted, buyers went ahead and purchased furniture or a car, only to find that the loan terms changed at the last minute (according to the CFPB). It's safer to postpone large expenditures and maintain your credit status until after closing.

Skipping the inspection is another mistake that isn't uncommon in areas with a competition index of 80, like ZIP code 91340. Seeing popular listings sell within 21 days can create anxiety that if you add any conditions, you might lose out, leading some to forgo the inspection condition. However, recent market trends indicate that in areas with older homes, skipping this step often results in repair costs later on.

There are also cases where buyers rush emotionally when it comes to neighborhoods with good school districts. Areas preferred by Korean families tend to sell out quickly when listings become available, which can create a sense of urgency. However, it's better to consider commuting distance, long-term living plans, and future resale potential before making a decision.

Families moving from other states often set their budgets based on property taxes or living costs from their previous locations, only to realize the actual burden in California later on. Since areas favored by Korean families tend to have higher sale prices, it seems practical to first calculate the total ownership costs, including property taxes and insurance premiums.

Ultimately, not exhausting your emergency fund on the down payment, reflecting property taxes and insurance premiums in your budget, and preparing for closing costs separately can be realistic ways to avoid financial strain after moving in.
