A family was looking to settle in Lexington. After deciding on this area for their child's school, the next question was whether to rent or buy. While searching for homes, they were momentarily speechless upon seeing the price tags.

According to Zillow, as of June 30, 2026, the average home value in Lexington is $1,626,351, which is a 2.3% increase from a year ago. In contrast, Zumper reported that the median rent for all bedroom types in March 2026 was $3,025, down 15% from the previous year. RentCafe estimated the average rent during the same period at $3,544, which is slightly different, but the trend is similar. Home prices are rising while rents are stabilizing.

The way to compare these two numbers is through the price-to-rent ratio, which is the ratio of home prices to rental costs. The calculation is simple: divide the home price by one year's worth of rent. Plugging in the Lexington numbers, dividing $1,626,351 by $3,025 for 12 months, which totals $36,300, gives a ratio of 44.8.

This ratio indicates that typically, a ratio below 15 favors buying, while a ratio above 20 is often seen as more financially advantageous for renting. The figure of 44.8 significantly exceeds that threshold, suggesting that Lexington is definitely a rental-friendly area.

Calculating with a mortgage leads to the same conclusion. With a 20% down payment, the loan amount would be around $1.3 million. Applying the average fixed interest rate of 6.65% as of August 20, 2026, from Freddie Mac, the monthly principal and interest would be about $8,300, nearly three times the rent of $3,025. Adding property taxes and insurance would widen the gap even further.

However, this does not mean that buying is always a loss. This calculation considers the opportunity cost of investing the down payment elsewhere instead of putting it into a home. If you plan to stay long-term and have no intention of leaving the area due to school district reasons, the situation may be different. Lexington is a neighborhood that consistently attracts families due to its school district reputation. However, school district boundaries change frequently, so it's advisable to check the assigned school for a specific address before purchasing.

If your stay is short or you might move to another area in the future, the current numbers suggest that renting is significantly less burdensome. Calculating the difference in monthly payments over several years can also help gauge the weight of the down payment tied up in a home.

For families who have recently moved from Korea, the property tax structure in a neighborhood like Lexington may be unfamiliar. Massachusetts has different tax rates and exemption systems by state and county, so this should be checked individually.

It's also worth considering how to prepare for a down payment. In high-priced neighborhoods like Lexington, you would need over $300,000 just to cover the 20% down payment. A strategy could be to save this amount over several years by using the difference from renting. If you save over $5,000 a month, you could theoretically accumulate the down payment in five years.

Overall, Lexington ranks among the higher-priced areas in the Boston Metro. Compared to nearby cities, it is rare to find such a significant gap between rent and home prices. If the reason for choosing this neighborhood is the school district, living in a rental while saving more funds could be a more realistic option.

Don't forget about closing costs. In Massachusetts, it's common for these to add an additional 2-3% of the home price. For a home priced around $1.6 million, closing costs could range from $30,000 to $50,000, so it's important to prepare for this separately from the down payment.

When compared to the national average, the gap in Lexington is particularly large. Even among top cities nationwide, many tend to stay in the mid to high 20s or low 30s, while Lexington reaches into the mid-40s. This indicates that renting is definitely more advantageous than buying in this area.

The family mentioned at the beginning ultimately chose to rent for the time being, enjoying the school district while separately growing their savings. While there is no definitive answer, reviewing the numbers first can clarify the reasons behind their choice.
