A recent client I consulted with mentioned that the monthly rent for a house purchased in San Fernando was $3,200, and they were considering this amount as their profit. This was a case of confusing total rent with net profit, and I had to clarify that the actual profit is what remains after deducting property taxes, insurance, and maintenance costs.

According to Zillow rental manager data, the median rent for all bedroom and property types in San Fernando is around $3,200. The same data indicates that the typical home value in San Fernando is $676,787. Redfin reports that the average home price over the past month is $732,000, which is an 18.1 percent increase from the previous year. As a small city within Los Angeles County, it tends to move in line with the overall market trends in the Valley.

Looking at property taxes, according to propertytaxrates.org, the effective tax rate for Los Angeles County is 0.69 percent, with a median tax bill of $5,438. However, this is an average for the entire county, and when the Prop 13 base rate of 1 percent is combined with local bonds and special assessments, the actual burden for new buyers often rises to between 1.1 and 1.3 percent. If a family is moving from another state, estimating expenses based on the property tax rate from their previous residence may lead to inaccuracies, so it's safer to verify with the county tax office data.

For a practical example, if we apply a slightly higher tax rate of 1.2 percent to a home purchased for $680,000, the annual property tax would be around $8,160. This is higher than the county's median tax bill of $5,438 because the purchase price in San Fernando Valley is generally above the county average.

Calculating the total yield, if we apply a monthly rent of $3,200 to a purchase price of $680,000, the annual total rent would be $38,400, resulting in a total yield of about 5.6 percent. This figure is relatively high compared to the purchase price in San Fernando Valley. However, it is important to note that this total yield does not account for any expenses.

Returning to the earlier confusion of the investor, if we apply the 50 percent rule and assume that property taxes, insurance, maintenance costs, and vacancy losses amount to half of the total rent, the net operating income would drop to around $19,200 per year. Dividing this amount by the purchase price gives a cap rate of about 2.8 percent, which is only half of the initially calculated 5.6 percent. This gap between total yield and cap rate illustrates the error that occurs when confusing net profit with total revenue.

It's also worth noting that rental prices varied between $2,450 and $3,200 across different research institutions. Depending on which data is used, the total yield can fluctuate between 4.3 percent and 5.6 percent, so it's most accurate to check recent contract examples near the property before finalizing any agreements. According to the 1 percent rule, 1 percent of the purchase price of $680,000 is $6,800, and while the actual rent falls short of this, it is relatively small compared to other California cities.

If financing is involved, cash-on-cash return must also be considered. This method calculates the pre-tax cash flow against the actual cash invested, including down payment and closing costs, and depending on the interest rate and loan ratio, it can be higher or lower than the cap rate. This is because the monthly mortgage principal and interest payments are deducted from the cash flow.

From the perspective of total returns, including appreciation and repayment of the loan principal, the recent 18 percent increase in San Fernando home prices can enhance investment appeal. However, it cannot be assumed that this upward trend will continue, and if the area is of interest to Korean families, it is advisable to verify school district ratings and boundaries, such as those from GreatSchools, before making a purchase.
