注意看这段公式 是如何计算的：
The typical U.S. home appreciated 7.6 percent over the past year, from a median value of $195,400 in February 2017 to $210,200 at the end of February 2018. That $14,800 bump in value translates to a gain in home equity of $7.09 for every hour the typical U.S. homeowner was at the office last year (assuming a standard 40-hour work week),[1] a shade less than the federal minimum wage of $7.25 per hour.
365（days）/ 7 = how many weeks we have within 2017 , == about 52.8 weeks
then (assume 40 hours per week), then use 14800 /52.8 == about 7.09 dollar per hour .
Homes 'Earn' Minimum Wage or More in Almost Half the Nation's Largest Cities
ByZillow Research on Apr. 9, 2018
Home values in San Jose, Calif., San Francisco and Seattle have been appreciating more than 3.5 times faster per working hour than the cities’ minimum wage workers earn.
In San Jose, the typical homeowner is gaining $99.81 of equity in their home every hour they’re at the office. The city’s hourly minimum wage is $13.50.
The typical U.S. homeowner is gaining $7.09 of equity in their home every working hour, $0.16 less than federal minimum wage.
The rapid pace of home value appreciation over the past year may present homeowners in several large U.S. markets with an interesting dilemma: Why work a 9-5 slog, when you can sit back and collect substantial hourly home equity “earnings” instead?
