According to the PMMS released by Freddie Mac, the average interest rate for a 30-year fixed mortgage remains around 6.6% as of July 2026. At first glance, this number doesn't seem to have changed much, but in areas like Hartsdale, which has a significant Korean community, the story is a bit different. More important than the fluctuations in interest rates is the unique inventory shortage in this area.

Data from Zillow indicates that the typical home value in Hartsdale, the ZHVI, is $677,751, which has increased by 1.2% over the past year. In contrast, the median sale price for Westchester County, which includes Hartsdale, was $999,000 as of February 2026, reflecting a 16.2% increase from the previous year. Even within the same county, the rate of increase varies by neighborhood, meaning that relying solely on the county average to assess the actual competitive buying conditions in Hartsdale could lead to significant discrepancies.

According to Redfin, homes in Hartsdale receive an average of two offers and go under contract in about 34 days. The overall average selling period for Westchester County was also shorter, at 50 days as of February 2026, down from 67 days a year earlier. The Hudson Gateway Association of Realtors reports that the county's inventory has decreased to just 1.4 months' worth. This suggests that it is realistic to view the market as one where multiple buyers are competing, favoring sellers.

The reason for such low inventory is the nationwide lock-in effect. Homeowners who secured loans at 3-4% during the ultra-low interest rates of 2020-2021 are reluctant to sell and switch to the current rates around 6%. This trend has been noted in market analyses by the National Association of Realtors (NAR) and Fannie Mae, and it feels even more pronounced in neighborhoods like Hartsdale, where inventory was already scarce.

The Greenburgh school district, which includes Hartsdale, has consistently attracted interest from Korean families commuting to New York City. While you can refer to ratings from sites like GreatSchools or Niche, keep in mind that school district boundaries can change over time, so it's advisable to verify which school a specific address is assigned to when reviewing listings.

Families moving from New Jersey, Connecticut, or even farther states into the New York commuting zone should pay particular attention to property tax burdens. The property tax rate in Westchester County often feels higher than in their previous states, and as sale prices rise, taxes can also increase after reassessment. Instead of budgeting based solely on home prices, it's more accurate to compare total ownership costs, including annual property taxes and homeowners insurance.

For investors looking for rental income, the cap rate and the 1% rule—checking if the monthly rent is more than 1% of the purchase price—can serve as initial screening tools. However, in areas like Hartsdale, where there is significant potential for price appreciation, cap rates tend to be lower, indicating a stronger focus on long-term value growth rather than cash flow. It's advisable to avoid excessive leverage or overly optimistic vacancy period estimates.

From my long-term observation of this local market, Hartsdale has been a neighborhood where prices are not easily swayed due to the scarcity of available homes, regardless of interest rate movements. If you are considering a purchase now, it's important to evaluate not just interest rate news but also inventory, school districts, and property taxes.
