A family that had been renting in San Jose for a long time decided to crunch some numbers one day. They wondered if their current rent could cover a mortgage payment. In the past, such calculations felt reckless due to the significant difference between home prices and rent, but the situation has changed a bit now. Those who have been observing for a long time are the first to notice these changes.

According to Redfin, the median home price in San Jose was $1,469,200 as of June, down 0.76% from a year ago. Zillow's average home value also decreased to $1,413,804, a drop of 1.8%. After years of continuous increases, San Jose home prices seem to have entered a period of stabilization over the past year.

In contrast, rent has moved differently. According to Zumper, the rent for a one-bedroom apartment is $2,700, which is a 10% increase from a year ago. With home prices decreasing and rents rising, the gap between rent and mortgage payments has narrowed compared to the past. This is why the family decided to do the math.

There are a few factors to check in such situations. The first is the price-to-rent ratio, which compares the home price to the rent. Dividing the average home value of $1,413,804 by the annual rent of $32,400 for a one-bedroom gives a ratio of around 43. A ratio above 20 is generally considered favorable for renting, so based on this number, renting still seems to be the better option.

The second factor is the actual mortgage payment. Just because rent is similar to the principal and interest of a mortgage doesn't mean buying is immediately advantageous. When property taxes, homeowners insurance, and maintenance fees are added, the total payment often becomes significantly higher than rent. In areas like San Jose, where home prices are high, this difference can be particularly pronounced. It's essential to avoid the illusion that a mortgage seems manageable just by looking at rent; it's necessary to recalculate based on total payments.

The third factor is the down payment. In San Jose, a 20% down payment would require around $283,000, which is a substantial amount. One strategy is to rent while monitoring the market until this money is saved. The fourth factor is the length of stay. If you plan to stay in the area for 5 to 10 years or more, what seems like a burdensome purchase price now could lead to stable homeownership in the long run. Conversely, if your stay is short or you might move in the future, there's no rush. If any of these four factors are uncertain, the conclusions drawn from the other three can easily waver, no matter how well they are calculated.

In the past, it was common for rent to be only half the level of mortgage payments, but now that gap has noticeably narrowed. However, it's premature to conclude that buying is immediately advantageous. A proper comparison requires looking at total costs, including property taxes and insurance. The longer you observe the market, the easier it is to fall for such illusions. Instead of hastily concluding that the numbers look close, it's safer to review each item carefully.

If a family prioritizes school districts, there are significant differences in assigned school ratings across neighborhoods in San Jose. Be sure to check the assigned school for the specific address before purchasing.

San Jose is a region that reacts sensitively to employment conditions in the Silicon Valley tech industry. When hiring increases, rental demand responds first, while the sales market often moves later based on interest rates and inventory conditions. California property taxes are assessed based on the purchase price and have a legally limited annual increase, so the longer you hold onto a property, the more stable your tax structure becomes.
