ATTOM分析：12月24日买房溢价全年最低、仅高出市值3.2%，7月是最佳买房月份
房地产数据公司 ATTOM 11月12日在加州 Irvine 发布年度最佳买房日分析：该公司统计过去10年超过4800万笔独栋住宅与公寓成交后发现，在12月24日完成过户的买家支付的溢价为全年最低，中位成交价仅比自动估值模型（AVM）估出的市值高3.2%；全年溢价最高的是5月27日，达14.5%。
其余低溢价日子集中在7月：7月10日溢价3.5%，7月9日4.1%，7月3日与7月2日均为4.3%，7月17日4.6%。全年溢价最低的10天里，有9天落在7月。
按月份看，7月是全年最佳买房月份，溢价6.3%；其次是11月的7.4%、10月的7.8%，9月与12月均为8.2%。
分州看，夏威夷州与密歇根州是仅有的两个在最佳月份出现折价的州：夏威夷州1月成交价比市值低1.8%，密歇根州11月低1.7%。康涅狄格州1月与明尼苏达州12月的溢价均为0.0%，伊利诺伊州11月仅0.1%，接近按市值成交。
这项分析覆盖2016至2025年间每个至少有1万笔独栋住宅与公寓成交的日历日，共362天，1月1日、7月4日、11月11日与12月25日不在统计内。溢价的算法是把在某一天过户的房屋，其中位成交价与同一批房屋成交时的 AVM 中位估值相比，高出的百分比即溢价，负值即折价；分析以过户日而非签约日为准。
ATTOM Analysis: Buyers Closing on December 24 Pay the Year's Lowest Premium at 3.2%; July Is the Best Month to Buy
Property data company ATTOM on November 12 released its annual best-days-to-buy analysis from Irvine, California: after examining more than 48 million single-family home and condominium sales over the past 10 years, it found that buyers who close on December 24 pay the lowest premium of the year, with the median sales price just 3.2 percent above the automated valuation model (AVM) value. The highest premium falls on May 27, at 14.5 percent.
The other low-premium days cluster in July: July 10 at 3.5 percent, July 9 at 4.1 percent, July 3 and July 2 at 4.3 percent each, and July 17 at 4.6 percent. Nine of the ten lowest-premium days of the year fall in July.
By month, July is the best month to buy, with a 6.3 percent premium, followed by November at 7.4 percent and October at 7.8 percent, with September and December both at 8.2 percent.
By state, Hawaii and Michigan are the only two states where buyers saw a discount below market value in their best month: 1.8 percent below in Hawaii in January and 1.7 percent below in Michigan in November. Buyers in Connecticut in January and Minnesota in December paid 0.0 percent premiums, and Illinois buyers in November paid just 0.1 percent, close to market value.
The analysis covered every calendar day from 2016 through 2025 with at least 10,000 single-family home and condominium sales, 362 days in total, excluding January 1, July 4, November 11 and December 25. The premium is calculated by comparing the median sales price of homes closing on a given day with the median AVM value of those same homes at the time of sale; a negative figure is a discount. The analysis is based on the closing day, not the day a contract is signed.
