Renting a 3-bedroom in San Jose costs about $4,100 per month, while the median price to buy a home of the same size reaches $1.55 million.

This number can be overwhelming. Should you buy, or should you continue renting? It's a tough decision.

First, let's calculate the Price-to-Rent Ratio. Dividing the median home price of $1.55 million by the annual rent of $49,200 gives us 31.5. Generally, a ratio below 15 indicates buying is favorable, while above 21 suggests renting is better. A ratio of 31.5 is particularly high, even within Silicon Valley. San Jose has seen home prices outpace rent increases due to the concentration of tech companies in the area, which likely explains this result.

Let's also look at the monthly payment. If you make a 20% down payment of $310,000 and borrow the remaining $1.24 million at a fixed rate of 6.75% for 30 years, your principal and interest payment would be around $8,043 per month. Adding property taxes of $1,421 and insurance of about $150 brings the total to approximately $9,613 per month. Compared to the rent of $4,100, this results in a monthly difference of $5,513, which can weigh heavily on your mind.

You should also consider the opportunity cost of investing the $310,000 down payment elsewhere. Even with a modest annual return of 6%, you could earn over $18,000 a year. Choosing to rent while investing instead of tying up your money in a home is a viable option. Of course, there is a possibility that home prices in San Jose will rise in the long term, but some industry perspectives suggest that the potential for significant increases is not as strong as it once was due to already high prices.

Comparing with nearby areas might provide some relief. San Francisco has a lower Price-to-Rent Ratio of 24.5 than San Jose, and if you look a bit further south to Morgan Hill or Gilroy, the rent burden relative to home prices is much more manageable. Within Silicon Valley, increasing your commuting distance can broaden your options.

• If your stay is short, maintaining a rental is a safer choice.
• If long-term settlement and school districts for children are priorities, consider buying.
• Check if you have the capacity to invest your down payment.
• Broaden your commuting radius and compare with nearby cities.

Of course, the answer can vary depending on your situation. If your children are already settled in the San Jose school district and you plan to stay in the area for over ten years, even if the monthly burden is high, buying could be a way to build equity in the long run. Conversely, if you might move to another state in a few years, maintaining your rental while growing your savings could be more comfortable and financially secure. Remember that you would need to manage a monthly difference of over $5,000 for 30 years, so be sure to calculate carefully before making a decision.

Many Korean families find it difficult to leave San Jose due to their children's education. For those individuals, I recommend maintaining your rental instead of rushing to buy, while steadily building your down payment funds, and waiting for mortgage rates to drop to the low 6% range. There's no need to rush your decision; it's perfectly fine to take your time.
