October Is Ripe for Homebuyers According to Analysis from ATTOM on Historical Home Sales

October 10 2021

Buyers willing to close in October avoid prices well above market value; Analysis narrows in on best days to buy nationwide and best months to buy at the state level

IRVINE, Calif. - Oct. 7, 2021 -- ATTOM, curator of the nation's premier property database, today released its annual analysis of the best time of the year to buy a home, which shows that the month of October, as well as the winter months, offer homebuyers the best deals – fetching lower premiums than other months of the year.

According to the analysis, buyers who close in October will get the best deal compared to the spring buying season. While the premium is still above market value, homebuyers are only dealing with a 2.9% premium, as opposed to the month of May, when homebuyers are experiencing an 11.5% premium. This analysis of more than 33 million single family home and condo sales over the past eight years is evidence of the continuation of a hot sellers' market (see full methodology below).

The analysis also looked at the best days to buy at the national level (December) and best months to buy at the state level.

Best Days to Buy

Nationally, days that fall in December offer the lowest premium for homebuyers. With December 5th seeing a 1.6% premium, December 26th a 2% premium, January 6th a 2.2% premium, November 9th a 2.3% premium and December 31st a 2.4% premium. A far cry from the month of May, where May 23rd and 27th offer a 17.4% premium, May 20th a 16.6% premium, May 16th a 15.6% premium and May 19th a 15.4% premium.

Best Months to Buy by State

According to the study, the states realizing the biggest discounts below full market value were Delaware (-7.9% in February); Tennessee (-7% in January); New Jersey (-4.9% in February); Maryland (-4.8% in November); and Ohio (-4.8% in January).


For this analysis ATTOM looked at any calendar day in the last eight years (2013 to 2020) with at least 10,000 single family home and condo sales. There were 362 days (including leap year data) that matched this measure, with the four exceptions being Jan. 1, July 4, Nov. 11 and Dec. 25. To calculate the premium or discount paid on a given day, ATTOM compared the median sales price for homes with a purchase closing on that day with the median automated valuation model (AVM) for those same homes at the time of sale.
